Consuming enough protein is particularly Optimmization for Digestive health promotion MPS, or Ophimization process by which amino acids are incorporated into Performancs muscle proteins to build and repair muscle tissue.

Eating enough protein can help preserve the muscle mass you already have while combining protein with resistance training can optimize MPS and help you build additional muscle mass.

Having a healthy amount of muscle is not only key for boosting performance, but also for curbing risk of sarcopenia age-related muscle losswhich is associated with poor mobility and early death.

Muscle is also more metabolically active than fatmeaning you burn more calories—even at rest—when you have more muscle mass. Distributing protein intake throughout the day, as well as consuming a balanced snack that contains protein, carbs, and healthy fats after strenuous workoutscan also help optimize MPS and muscle gains.

But protein can do a lot more than build muscle. For one, including adequate protein and fat in meals helps stabilize post-meal blood sugar levels. Additionally, amino acids are an important component of enzymes, proteins that catalyze every chemical reaction in the body. Plus, plant proteins are associated with enhanced longevity.

Just aim to limit your protein intake from highly processed meats such as bacon, pepperoni, sausage, deli meats, and hot dogs, which are more strongly linked to cardiovascular disease and various cancers.

While carbs and protein often get all the hype when it comes to eating for optimal fitness, fat is just as crucial for overall health and well-being. Like protein, one of the most immediately noticeable benefits of including fat in your meals is that it promotes stable blood sugar and helps keep you full, Cording says.

Fats also aid in the absorption of fat-soluble compounds in our food, from the vitamins A, D, E, and K to carotenoid antioxidants and sterols plant compounds with cholesterol-lowering properties. Once dietary fats are broken down into fatty acids and absorbed via the lymphatic system and bloodstream, fatty acids can serve as a structural component of cells, building blocks of signaling molecules, and a concentrated source of energy a gram of fat provides 9 calories, while a gram of carb or protein provides 4.

Fatty acids from dietary fat or stored body fat are also used to produce steroid hormonesincluding testosterone, estrogen, and progesterone. A meta-analysis of studies found that low-fat diets may be associated with decreased testosterone production in men compared to higher-fat diets.

Healthy testosterone levels not only positively impact sexual function, but also support optimal muscle growth, bone strength, and more. But not all sources of fat are equally beneficial. Your best bet: Focus on sources of unsaturated fats, including monounsaturated fats MUFAs and polyunsaturated fats PUFAs like omega-3s and omega-6s.

Try to also minimize intake of saturated fat SFAwhich contributes to elevated LDL cholesterolarterial plaque buildup, and inflammation. Replacing SFAs with unsaturated fats is associated with a reduced risk of death from a variety of diseases, including cardiovascular disease and cancer.

To get a solid balance of macronutrients in your diet, aim for meals and snacks to contain a mix of minimally processed carb-rich, protein-rich, and fat-rich food sources. Focus on unrefined, minimally processed carb-containing foods, which naturally contain fiber and a variety of beneficial phytochemicals.

Here are a few examples to add to your grocery list:. Whole grains like oatmeal, brown rice, quinoa, wheat berries, barley, and farro. Whole-grain varieties of bread, sandwich wraps, English muffins, pastas, and pretzels.

Non-starchy vegetables like leafy greens, broccoli, asparagus, green beans, cabbage, Brussels sprouts, zucchini, cucumber, tomato, bell pepper, celery, and eggplant.

Starchy vegetables like potatoes, sweet potatoes, parsnips, squashes, beets, corn, turnips, and carrots. Fruits like bananas, mango, apples, berries, and melons. Beans, peas, and lentils. Focus on high-quality animal products while trying to limit processed meats and protein-rich plant foods.

Remember: Eating a variety of plant foods will help ensure you get all nine essential amino acids. Here are a few protein food sources to keep in mind:. Nuts almonds, pistachios, and peanuts.

Nut butters almond butter and peanut butter. Focus on nutrient-dense foods rich in unsaturated fats, including PUFAs omega-3s and omega-6s and MUFAs, and minimize intake of saturated fats. Here are some fat sources to consider adding to your plate:.

Extra virgin olive oil. Nuts and nut butters. There is, however, something called the Acceptable Macronutrient Distribution Ranges AMDR set forth by the National Academy of Sciences, which suggests that adults consume 10—35 percent of our calories from protein, 20—35 percent from fat, and 45—65 percent from carbohydrates.

Protein needs are also commonly determined based on body weight, with a recommended dietary allowance RDA of 0. When it comes to protein specifically, some research suggests that people engaging in low, moderate, and intense physical activity should get more than the RDA guideline—1.

Following the same example above, that would work out to be 68, 89, or grams of protein per day for a pound person. Interestingly, for people who menstruate, the optimal macro ratios can change throughout your cycle.

Getting more of these nutrients at this time could help support satiety if you struggle with cravings or feeling extra hungry right before your period. Probably not. While some people meticulously track macros for various reasons—from bodybuilders looking to lower body fat and build muscle to people with diabetes trying to stabilize blood sugar levels to distance runners looking to boost recovery—counting macros may not be so beneficial for the average person.

And for some, particularly those with a history of eating disorders, it could lead to a disconnection from hunger and fullness cues, an unhealthy preoccupation with food, and a lack of dietary flexibility.

Instead, most nutrition experts recommend eating a generally balanced diet and then increasing or decreasing your intake of protein- carb- and fat-containing foods based on how you feel and your personal health goals.

If you do want to track macros for a specific health goal, consider working with a registered dietitian at least initially who can get you started on an appropriate plan for your needs.

sweet potatoesand use a little fat in your cooking. You can shift those ratios to help tweak how you feel and, of course, not every meal has to look like that. Consider options like an apple with string cheese, whole wheat toast with peanut butter and banana, or trail mix with nuts, seeds, and dried fruit.

Getting a balance of macronutrients is essential for your well-being and supporting a healthy fitness routine. Carb-containing foods provide energy for workouts, help preserve your muscle mass, and can be a great source of micronutrients; protein-rich foods support tissue growth and repair, boost muscle gains, promote stable blood sugar, and support immune function; and sources of healthy dietary fats create healthy cells, promote stable blood sugar, enhance absorption of nutrients, support hormones, and even curb inflammation.

Getting adequate amounts of each macro and boosting your intake of micronutrients in the process is best accomplished by including a balance of minimally processed carb- protein- and fat-containing foods at each meal and snack, and adjusting based on how you feel.

Explore Protein-Rich Macro Guide with Scitron	Carbohydrates also are important for recovery and help to build muscle. There are simple and complex carbohydrates. Simple carbohydrates are found in sugary foods such as sweets and candy. Complex carbohydrates are found in whole grain foods, vegetables such as potatoes, legumes and beans and fruits that contain many vitamins and minerals. The second macronutrient is protein. Proteins helps to build tissues in your body, like skin and muscle. Fats are the third macronutrient. You may think that fat is something that needs to be eliminated or reduced from your diet. You are correct in thinking that it needs to be reduced. Knowing what to reduce is the key question. Fat is important to your health and performance and is the primary fuel we burn when at rest and during low-moderate intensity activity or exercise. The fat that needs to be reduced in your diet is fat that is solid at room temperature. This type of fat is called saturated fat. Butter, lard, whole or full-fat dairy products and coconut oil are all examples of saturated fats that should be eaten in moderation. Unsaturated fats, or fats that are liquid at room temperature derive from a plant source and are healthier fat options; examples include canola or olive oil, fish oil, seeds and nuts. Eating these macronutrients throughout the day is important for sports performance or as part of a balanced, active lifestyle. Michigan State University Extension offers community based nutrition and physical activity programming across the state. In addition, Spartan Performance , a MSU Sports and Cardiovascular Nutrition program is also available as individual and team development. Regardless of the activity you chose, be sure to fuel your body appropriately to ensure you maintain optimal health. This article was published by Michigan State University Extension. Three MACroNutrients. Did you find this article useful? Please tell us why? I'll use my macro intake as an example. First, you need to know how many calories you eat or want to eat each day. I eat roughly 2, calories per day. Next, determine your ideal ratio. If you don't like math, don't fret. The internet is home to a range of macronutrient calculators that will do the math for you. IIFYM stands for "If It Fits Your Macros" -- a phrase and popular hashtag used by the macro-tracking community to refer to their flexible dieting approach. This calculator is one of the most comprehensive available. It collects lifestyle and health information that many calculators don't, such as how active you are at work, what kind of cravings you have and whether you have any medical conditions. The IIFYM calculator takes into account your daily routine and other important factors. Healthy Eater's macro calculator calculates your macronutrient ratio based on your age, gender, height, weight and activity level. I like this macro calculator because you can see your ratio in terms of all day, three meals, four meals or five meals. This macro calculator uses your lean body mass LBM , basal metabolic rate BMR and total daily energy expenditure TDEE to calculate an accurate ratio. The Legion Athletics macro calculator is another very detailed calculator. It takes into account your weight, your body fat percentage, and your activity level. From there, this calculator determines your lean body mass, basal metabolic rate and total daily energy expenditure. The upside to this calculator is that you get a more accurate ratio because it considers more factors. The downside is that you need to know your body composition before using it. You choose whether you want to gain, lose or maintain your current weight, and you can use the sliders at the bottom to adjust your ratio if the automatic recommendation isn't ideal for you. It sounds scary, but again, the web comes to the rescue with a slew of digital macro-tracking programs. The free version of MyFitnessPal doesn't allow you to enter gram amounts for macros, only percentages. If you're comfortable with percentages only, then MFP is a great free option because of its barcode scanning feature and massive database of foods and drinks. The MyFitnessPal dashboard breaks down your macronutrient intake with a helpful pie chart. With a premium subscription, you can track by gram amounts and percentages, and you can see macro breakdowns for each meal and snack. A premium subscription also gets you extra features like food analyses quality of what you're eating , food timestamps when you eat what and weekly reports. MyMacros Plus is another great app with a large food database and barcode scanning feature. You can also track your body weight and enter custom foods for homemade recipes so you don't have to log the individual ingredients. My favorite thing about MyMacros Plus is that it's usable without the internet, so you can track macros even when you're offline. Tip: Food databases are helpful, but they often include multiple entries with different information for the same item, which can get confusing. It might be easier to manually log the macronutrients in your meals instead of relying on the food database. The Cronometer tracker tracks vitamins and minerals in addition to macros. It also allows you to track important biometrics, such as blood pressure, cholesterol, sleep, mood, pulse and more — but you first need this information on hand to use the features. If you do have access to that information, Cronometer provides insight into long-term trends and a clear snapshot of your overall health. While Cronometer is impressive, it can be a bit overwhelming if you only want to track macros, and not the rest of the metrics it offers. Know that you don't need to track macros to be healthy, lose weight, build muscle or reach any other health goal. The only time you actually need to track macros is if your doctor told you so. In fact, logging your every bite can be frustrating and time-consuming, but it's worth noting that you'll get pretty good at eyeballing portions if you make tracking a habit. Tracking macros can definitely be useful for some things, such as preparing for a bodybuilding show or optimizing athletic performance. It can also be helpful if you want to implement "flexible dieting," or the practice of eating any foods you want, as long as they fit into your macronutrient ratio. Counting your macros may also be the key to finally eating less processed foods , as processed and packaged foods tend to be high in fats and carbs and not often high in protein , and adding in more superfoods. Many people who want to create a calorie deficit to lose weight prefer tracking macronutrients instead of counting calories, as it takes the emphasis off of weight loss and shifts the focus to nutrition. This is helpful for creating long-term healthy habits. Additionally, many people enjoy tracking macros because it helps them understand what types of foods work best for their bodies. Give it a try to see if it works for your lifestyle, but don't feel like you ever need to track your macros. Meal Delivery. Dieting Program Guides. Vitamin and Supplement Guides.

What is the importance of macronutrient balance for athletes? Gowtham Srinivas September 20, Achieve Your Peak Performance: Unleash the Power of Macronutrient Balance!

Understanding Macronutrients Macronutrients are the three main components of our diet that provide energy to the body.

They are broken down into glucose, which is used by the muscles and other tissues during exercise. Carbohydrates also help replenish glycogen stores, which are essential for endurance and high-intensity activities.

Athletes should aim to consume complex carbohydrates such as whole grains, fruits, and vegetables to sustain energy levels and support optimal performance. Proteins: Proteins are the building blocks of muscles and are essential for muscle repair, growth, and recovery.

Athletes require an adequate intake of protein to support muscle development and repair, especially after intense workouts. Good sources of protein include lean meats, poultry, fish, eggs, dairy products, legumes, and plant-based proteins like tofu and quinoa.

Woodland caribou Rangifer tarandus caribou also occur in the more northerly Kakwa region of west-central Alberta. Ungulate consumption peaks in June and remains relatively high in July. Green vegetation becomes common in grizzly bear diets in June with consumption peaking in July.

Commonly consumed native forbs include horsetails Equisetum spp. and cow parsnip Heracleum lanatum [24]. Forbs associated with anthropogenic disturbance e. Sweetvetch root consumption is generally low during July; however, bears in the mountains continue to consume roots throughout the active season likely due to environmental gradients allowing for prolonged availability of nutritious roots and limited availability of animal-based foods [24] , [39].

Fruit is prominent in the diet of grizzly bears in west-central Alberta from as early as late July, with consumption peaking in September [24].

Fruit most commonly consumed by bears in the study area include russet buffaloberry Shepherdia canadensis and those of the blueberry-huckleberry complex Vaccinium spp.

The consumption of green vegetation declines during the fruit season, while ungulate consumption continues for bears in the foothills, but is lower among bears in the mountains [24]. Insects, primarily ants, are consumed mostly in July and August.

In late fall, approximately mid-September to mid-October, a decline in the variety of available food resources has bears consuming a diet similar to the pre-green-up period: alpine sweetvetch roots once again becomes a primary food resource, and to a lesser extent ungulates [24].

Unlike the pregreen-up period, however, fruit is also often consumed by bears in the late-fall period [24]. Macronutrient estimates for several food items were obtained from previous bear studies, the USDA National Nutrient Database [41] , and other sources Supporting Information S1.

Chosen food items were considered generally sufficiently abundant for bears to effectively mix their diet based upon previous diet studies in the study area [24] , [40]. We used available carbohydrate estimates for foods only when total dietary fibre TDF was reported in order to more closely approximate the digestion of bears [42] and to better compare with the study of Erlenbach et al.

Fibre estimates, however, were not often reported as TDF, and we were therefore limited by a lack of suitable available carbohydrate estimates for foods, especially vegetation.

Since complete or suitable macronutrient estimates for some vegetation were unknown to us, we included vegetation proxies and combined some estimates from different sources to estimate available carbohydrate Supporting Information S1. For example, we used celery Apium graveolens var.

dulce as a proxy for cow parsnip because they are similar in nutrient content [43]. Limited data analysis for some grizzly bear plant foods are presented in supplementary material Supporting Information S1 and were used to inform macronutrient estimates. We used the USDA National Nutrient Database [41] to estimate macronutrient values for some wild ungulate tissues not reported in grizzly bear literature including brain, kidney, liver, tongue, eyeball, and bone marrow by using estimates from both wild and domestic animals Supporting Information S1.

We note that methods of diet composition may be different among studies, nutritional composition of food available to bears may differ from published data, and that food composition varies with respect to season and environment [21] , [39] , [44].

For the first estimate, we assumed an ungulate carcass was composed of five edible components We then averaged macronutrient estimates, including available carbohydrate, for each ungulate component per season, weighted them according to the proportion of edible carcass, and summed the components to estimate the macronutrient content of a non-selectively consumed ungulate Supporting Information S1.

Estimates for bone marrow and adipose tissue were not averaged as we used only single estimates for each component. A second estimate of non-selective ungulate consumption for moose minus hide and injesta was derived from Hundertmark et al.

Carbohydrate was not reported in Hundertmark et al. A third model of non-selective ungulate consumption was derived from McCullough and Ullrey [47] for white-tailed deer. We used data presented in Table 1 and Table 2 of McCullough and Ullrey [47] to estimate the macronutrient composition of male and female deer of three different age classes fawn, yearling and adult minus hide hair and skin , hooves, and antlers where present.

Estimates from McCullough and Ullrey [47] were derived from fall and winter animals following a high food resource year and as such were in excellent body condition high body fat.

We considered carbohydrates to be negligible for this estimate. We used right-angled mixture triangles RMTs to examine the relationships between seasonal food availability to grizzly bears, macronutrient availability and macronutrient requirements [34] see also [48]. RMTs represent 3-component e.

protein, fat and carbohydrate compositions of mixtures as Cartesian points in a multi-dimensional nutrient space. We used Erlenbach et al. Grizzly bears also showed a strong regulatory preference for the protein intake target despite different diets, with lipid and carbohydrate being interchangeable components of non-protein energy intake [32].

Within RMTs fat and available carbohydrates were represented on the two primary x and y axes, and crude protein on the third, implicit, axis the z axis. The implicit component varies inversely as distance from the origin increases [34].

Macronutrients were expressed as a percentage of total metabolizable energy kcal per food item Supporting Information S1 using Atwater factors [49]. In order to examine temporal patterns in macronutrient availability, we created RMTs for four periods of the grizzly bear active season.

These seasons were: 1 pre-green-up approximately late April to late May ; 2 forb and graminoid season approximately June through July ; 3 fruit season approximately early August to mid-September ; and 4 late fall approximately mid-September to mid-October.

We used non-selective ungulate consumption estimates when creating nutrient space polygons in order to better approximate the nutrient space available to grizzly bears. The estimates from McCullough and Ullrey [47] were used for all seasons, but may overestimate the fat content of ungulates during pregreen-up, graminoid and forb, and berry seasons.

Selective consumption of fatty ungulate components e. bone, marrow and brain were considered unlikely to contribute substantially to a balanced diet due to their size [45] and relative availability; however, we plotted macronutrient estimates of individual organs in order to illustrate the variety in nutrient composition among body parts.

Small mammals were omitted from the nutrient space because they are generally a minor diet item and limited in size, although they may be a more prominent food in the diet of some bears [24] , unpublished data. Overlap between the nutrient space polygon and intake target line would indicate that bears could optimize protein to non-protein energy intake by mixing their diet among seasonally available food.

In order for an ungulate carcass to be composed of an optimal ratio of protein to non-protein energy, it would need to have a percent mass ratio of crude protein to lipid of 0.

Conversely, an optimal ungulate carcass would need to contain approximately 2. These ratios are the same for both percent dry matter and percent fresh wet matter estimates.

Alpine sweetvetch root was close to optimally balanced in protein to non-protein energy due to its relatively high carbohydrate content. Small mammals would contribute mainly protein to the diet.

Protein is represented by the third z -axis which varies inversely with distance from the origin. Seasons are defined based on major changes in grizzly bear diet, and include: a pregreen-up; b graminoid and forb season; c berry season; and d late fall. The grey-shaded polygon indicates the estimated nutrient space available to grizzly bears consuming seasonal foods.

Overlap between the nutrient space polygon and the intake target line indicates that an optimal diet may be achieved during a season. The food items plotted do not include variation and are meant to give a general perspective.

During the graminoid and forb season, the addition of vegetation and ants to the diet allows bears to come closer to optimal protein intake by consuming a wider variety of carbohydrates and lipids Fig.

The ratio of protein to non-protein energy in available foods is higher than optimal during this season. Several individual fruits were close to optimally balanced in protein to non-protein energy. During late fall, grizzly bears can still potentially optimize their protein to non-protein energy intake by consuming fruit with alpine sweetvetch and whole ungulates Fig.

In the absence of fruit, grizzly bears face a diet that is similar in macronutrient composition to the pregreen-up period. Our analysis suggests that grizzly bears in west-central Alberta optimize macronutrient intake during seasons in which fruit is available. Fruit is commonly known as an important resource for bears, and is actively sought after, forming the bulk of bear diets during late-summer and early-fall when available [24] , [50].

The ability of bears to optimize their macronutrient intake by consuming fruit helps explain why it is such a highly desirable food item. The timing of fruit availability is also critical: berry season coincides with the hyperphagic period in which bears attempt to accumulate sufficient fat reserves to support hibernation and female reproduction costs [51] — [53].

Beyond simply supplying energy to hyperphagic bears, fruit enables grizzly bears to optimize mass gain per unit energy intake. The availability of fruit, therefore, has direct implications on the reproductive success and fitness of grizzly bears in the study area.

Diet studies within the study area [24] , [40] report that bears in the foothills have a much more carnivorous diet than bears in the mountains where ungulates and other animals are less abundant [24]. Our analysis shows that it is unlikely for grizzly bears to be able to optimize their diet by feeding non-selectively on ungulates, given that a balanced ungulate carcass would need to contain over two times the lipid as protein.

For example, assuming an average crude protein content of Such a high fat content is unlikely given that the average moose carcass in the same study contained 8. Additionally, the majority of ungulate consumption in the study area occurs during spring [24] , a time when prey tend to be lean [44] , [54].

However, despite not being perfectly balanced, ungulates provide more digestible protein and energy than plant-based grizzly bear foods [45]. Vegetation is complementary with ungulate consumption, in that it dilutes the level of protein in the diet and brings the diet closer to the protein intake target.

This seems to be reflected in the diet of bears within the study area, which maintain the consumption of graminoids, forbs, and horsetails during periods of high ungulate intake [24]. Grizzly bears tend to gain lean mass in the spring [28] which seems consistent with a high protein diet.

Since fat-rich resources are relatively scarce in west-central Alberta, we would expect fatty ungulate tissues to be highly sought after. Selective feeding behaviour has been observed in Alaskan grizzly bears that fed on lipid-rich brain tissues and roe of spawning salmon [55] ; however, as previously mentioned both wild and captive bears tend to consume ungulates in their entirety with the exception of hide and large bones [28].

It may be possible that bears in the study area selectively eat high fat ungulate tissues in order to increase their lipid intake, but presumably there are strong ecological constraints on availability to prevent bears from acquiring enough carcases to optimize their diet this way.

This would be especially relevant for scavenged carcasses, as lipid rich tissue is often the first to be consumed and spoils more readily [45]. Certain individual foods were closely balanced in protein to non-protein energy, and these foods are also prominent in the grizzly bear diet.

For example, celery proxy for cow parsnip , horsetail, and dandelion were closely balanced in macronutrients. The near optimal macronutrient balance of sweetvetch root may help explain why it makes up much of the bear diet during pregreen-up and late fall [24].

Yet, despite favorable macronutrient balance, plant foods other than fruit are often low in nutrient concentration. Grizzly bears may respond to high levels of non-nutritional fibre and low macronutrient concentrations in roots, graminoids, and forbs by consuming these foods in greater quantities a phenomenon observed in other animals [8].

Ultimately, however, grizzly bears are constrained by intake rates and stomach capacity when consuming energy- and macronutrient-dilute herbaceous foods [56]. Interestingly, for vegetation which we could estimate phenological changes in macronutrients, a decline in protein content from graminoid and forb season to berry season made these plants more closely balanced in macronutrients; however, nutrient concentration in these plants is generally lower and fibre content higher [21] , [23].

The macronutrient balance of ants makes them a potentially important food item for grizzly bears. Our results suggest that lipid content of ants makes them a particularly valuable food resource, because they allow bears to expand their nutrient space in the absence of high-fat ungulates and consume a diet that is close to the balance offered by preferred high-lipid diets.

As well, ants have previously been suggested to provide necessary amino acids to bears on largely vegetarian diets [57]. Ants, however, are generally not heavily consumed by grizzly bears in the study area and only for a limited time [24].

Therefore, the dietary impact of ants on the study area population is likely limited. Most food available to bears in the study area were high in protein relative to lipid or carbohydrate, and it is not unreasonable to suggest that a paucity of lipid-rich resources in part limits the study area population in terms of body size and population density relative to bears in ecosystems that provide more fatty foods e.

Yet, in the face of a suboptimal diet, generalist omnivores such as the grizzly bear may have a high capacity for capitalizing on excess nutrients in nutritionally imbalanced foods, even if it means deviating further from optimal nutrient intake [8]. One explanation for this is that a generalist species that has over-ingested a particular macronutrient has a relatively higher probability of encountering a complimentary food that enables it to correct the nutrient imbalance, thereby rendering the initial excess nutrient useable while also balancing the nutrient deficiency in the complimentary food [58].

This ability to capitalize on excess nutrients may be especially true of animals that readily store excess energy as fat [58] , which likely includes grizzly bears. Given that grizzly bears tend to consume large amounts of seasonal food resources, they may be able to effectively mix their diet across longer time periods, which has been previously suggested [27] , but has yet to be demonstrated.

While an optimal ratio of protein to non-protein energy could be consumed by grizzly bears in west-central Alberta, the absolute amount of food consumed would need to be adequate to support maintenance and growth.

The possibility for growth is obviously not always available to bears given inter-annual variation in both ungulate densities and berry production. Other factors may limit the availability of food resources to individual grizzly bears, including sexual segregation of habitats [30].

Yet despite the challenges, years of high resource availability should be those in which bears experience the greatest growth, not solely because of increased energy availability, but also due to the increased potential for optimizing macronutrient intake through a mixed diet.

So, how does counting macros for weight loss work? Serious athletes have long paid attention to their macronutrients—also known as macros —as a way to optimize their performance. But more recently, macro-focused diets also known as flexible dieting have become popular among fitness enthusiasts and people who want to keep their weight in check.

The macro diet, not to be confused with the macrobiotic diet, is all about counting the percentage of macronutrients—those being carbohydrates, fats, and proteins—in the diet and hitting a specific percentage target of the three, says Melissa Prest, D.

Meet the Experts: Georgie Fear, R. So what is the macro diet all about and is it something worth trying? Here are the answers to all of your questions—including exactly how to get started.

The idea behind the macro diet is pretty simple: Instead of staying under a calorie threshold, you focus on getting a certain number typically grams of macronutrients—protein, carbohydrates, and fat—instead. Depending on your goals, you can adjust the amounts of protein, carbohydrates, and fats you consume to slim down, build muscle, or maintain your weight.

Macronutrients are the three types of nutrients that provide you with most of your energy: carbohydrates , protein , and fat. Micro nutrients, on the other hand, are the types of nutrients that your body uses in smaller amounts, like vitamins, minerals, antioxidants, and phytochemicals.

For instance, chicken is a protein even though it also has some fat, and sweet potatoes are considered a carb even though they have a bit of protein. Not all macronutrients are created equal.

For example, here are healthy choices in every macronutrient category:. Carbohydrates: Healthy carbs are typically high in fiber , including whole grains, legumes, leafy greens, potatoes, and fruit.

Proteins: Good picks for healthy, lean proteins: chicken, turkey grass-fed beef, fatty fish like salmon and mackerel , eggs, and plant-based options like beans and chickpeas.

Fats: Satiating, healthy fats include olive oil, avocado, nuts, and seeds. There are several benefits in counting macros versus counting calories. First, it may help you make more nutritious choices by forcing you to consider the quality of your food. And if weight loss is your goal, counting macros has one major benefit: People following a macro diet tend to eat a little more protein than the average eater.

So, a macros diet could help you feel more full between meals. Perhaps the biggest benefit of a macro diet is having the flexibility to choose foods you truly enjoy, as long as it fits your macro plan.

Finding a good balance of nutrient-dense foods is important, but choosing an IIFYM plan allows you the freedom for an occasional indulgence, which, for many people, makes it easier to stick to in the long-run. In some cases, counting macros is easier than counting daily calories, but not always.

As with any diet plan that focuses on counting, it can be rather time-consuming and difficult to sustain for the long term, says Keri Gans, M.

The macro diet also tends to turn meal and snack time into a puzzle. That can be tough since very few foods are made up of just one macro.

Protein plays a fundamental role in muscle repair, immune function, and overall body maintenance within the context of a macro diet.

Macronutrient Balance and Performance Optimization -

Starches, on the other hand, take the body longer to digest, having a slower release of energy. Starches are considered a complex carbohydrate and are found in foods, such as beans, rice, bread, and oats. Starches are digested slower and tend to produce more sustained energy.

As another complex carbohydrate, fiber promotes a healthy digestive tract and keeps you feeling full for longer. A diet high in soluble fiber is linked to lower cholesterol and blood sugar levels , while regular insoluble fiber intake helps with digestion and may help prevent diverticular disease.

The body needs all three types of carbohydrates to work at its best. Carbohydrates are broken down into glucose, which then is used by the body. Extra glucose is stored as glycogen in the liver and the muscles.

Glycogen from the liver can be converted to glucose to help the body maintain stable glucose levels, while glycogen from the muscles is used to perform mechanical movements. We recommend including carbohydrates mainly complex sources as a part of a balanced diet.

A registered dietitian can help you determine how to optimize the nutrient density of carbohydrate foods in your diet and understand how to time your carbohydrate intake for improved athletic performance.

When you work with a registered dietitian who is a performance nutritionist or health and wellness coach you learn that fats play a crucial role in nutrient absorption and satiety. Fats are necessary for the body to transport and absorb certain antioxidants and vitamins, including vitamins A, D, E, and K.

Fats are also found in our cell membranes and are needed for blood clotting, healthy skin, and proper nervous system function. Fats slow down digestion and help you feel full longer which makes them a key nutrient in macronutrient balance. Your diet and nutrition coach will encourage you to prioritize unsaturated fats in your diet.

Unsaturated fats are beneficial because they can improve cholesterol levels and are considered anti-inflammatory. Prominent sources of unsaturated fats include plant-based oils, fatty fish, nuts, seeds, and avocados. In contrast, saturated fats are found in animal products, such as meat and dairy, and in plant foods, such as coconut oil and palm oil.

Your macro coach would likely recommend that you replace saturated fats with unsaturated fats as a part of your overall macronutrient balance to reduce the risk of heart disease.

Protein is found in every cell in your body — it is found in bones, muscles, hair, tendons, skin, and tissues. Proteins are important for muscle repair after exercise, and they play a central role in satiety and hormone secretion. Animal proteins provide vitamin B12, iron, zinc, and vitamin D, while plant-based proteins provide B vitamins, potassium, and magnesium.

Proteins are made up of basic building blocks, called amino acids. The body can create some amino acids naturally while others must come from food. Most major plant-based proteins, except soy, are incomplete. Tracking protein and understanding how much you need at each meal and in each snack is often a primary focus in macro coaching.

As you plan any meal or snack, your sports nutrition coach will recommend specific macronutrient target amounts that optimize energy, satiety, and recovery.

For example, your coach might recommend a pre-workout fuel of ~30 grams of carbohydrates to help you get the most out of your workout. Another example would be your coach setting meal-based targets for protein intake, such as 20 grams for breakfast, 30 grams for lunch, and 40 grams for dinner.

Each person is different and has diverse nutritional needs; however, getting a personalized plan can make a significant difference. If you are training for an athletic goal, for example, your diet must support your increased energy needs and, naturally, you would require a different diet than someone leading a more sedentary life.
