Turmeric is a bright yellow spice that is loved for its flavor, color, and medicinal properties. Curcumin enhances fat loss, decreases belly fat, and enhances your weight loss efforts. Curcumin blocks the synthesis of fat. Turmeric provides anti-inflammatory properties that reduce systemic inflammation.

It can also suppress fat tissue growth and regulate glucose levels by lowering insulin resistance. Finally, turmeric increases bile production, which is used by the body to emulsify fat.

Ginger is a plant from Southeast Asia and has been used in Traditional Chinese Medicine for centuries. The main compound in ginger is gingerol and provides many of the medicinal properties found in this potent, yet delicious herb.

Ginger provides powerful anti-inflammatory effects and helps reduce oxidative stress in the body. Ginger supplements can help significantly reduce body weight and waist to hip ratio.

Ginger also helps reduce BMI and insulin levels. Research has shown that ginger increases metabolism while reducing systemic inflammation. Oregano is a potent, fragrant herb used in Italian cooking. This delicious herb has powerful compounds and antioxidants that can help you lose weight and feel great.

Oregano contains terpenoids, terpenes, and phenols, including carvacrol, thymol, and rosmarinic acid. Carvacrol may boost your weight loss efforts.

It works by affecting specific proteins and genes in the body that are responsible for controlling fat synthesis. Oregano also helps to reduce systemic inflammation and reduce pain , so you can exercise more. Fenugreek has been used in alternative medicine for many years and is also an herb used in a plethora of Indian dishes.

This household spice gives a sweet, nutty flavor to your dishes. One tablespoon of fenugreek seeds provides iron, magnesium , and manganese to support health.

Fenugreek may also help with metabolic conditions like diabetes. One study found that taking 50 milligrams of fenugreek powder with meals can improve glucose levels, improves insulin function, and reduces bad cholesterol levels.

Fenugreek helps control appetite thanks to its fiber content. Reduced hunger and food intake can aid in weight loss. Ginseng is another herb commonly used in alternative medicine. This root plant has been studied extensively. Research has proven time and time again that ginseng can help boost metabolism and aid in weight loss.

When ginseng is combined with daily exercise and a healthy diet , you will lose more body fat and weight than those who depend on exercise and diet alone. Ginseng affects the metabolism of fat and cholesterol through its effects on adiponectin, leptin, and insulin.

The active compounds in ginseng ginsenosides stimulate fat loss at a molecular level, which helps decrease hunger and maintain insulin levels.

Finally, ginseng increases your energy levels and reduces fatigue. It is important to know that herbs can provide many medicinal benefits as well as enhance the flavors of foods. Diet and Nutrition.

Succinyl-CoA is converted to succinate, which is converted to fumarate, and then to malate. Malate is converted to oxaloacetate. Then, the oxaloacetate can react with another acetyl-CoA molecule and begin the TCA cycle again.

In the TCA cycle, electrons are transferred to NADH and FADH 2 and transported to the electron transport chain ETC. The ETC is represented by a yellow rectangle along the inner mitochondrial membrane.

The ETC results in the synthesis of ATP from ADP and inorganic phosphate P i. Fatty acids are transported from the cytoplasm to the mitochondrial matrix, where they are converted to acyl-CoA.

Acyl-CoA is then converted to acetyl-CoA in beta-oxidation reactions that release electrons that are carried by NADH and FADH 2. These electrons are transported to the electron transport chain ETC where ATP is synthesized. Amino acids are transported from the cytoplasm to the mitochondrial matrix.

Then, the amino acids are broken down in transamination and deamination reactions. The products of these reactions include: pyruvate, acetyl-CoA, oxaloacetate, fumarate, alpha-ketoglutarate, and succinyl-CoA, which enter at specific points during the TCA cycle.

This pathway is known as β-oxidation because the β-carbon atom is oxidized prior to when the bond between carbons β and α is cleaved Figure 6. The four steps of β-oxidation are continuously repeated until the acyl-CoA is entirely oxidized to acetyl-CoA, which then enters the TCA cycle.

In the s, a series of experiments verified that the carbon atoms of fatty acids were the same ones that appeared in the acids of TCA cycle. Holmes, F. Lavoisier and the Chemistry of Life. Madison: University of Wisconsin Press, Krebs, H.

Figure 4. The Fatty Acid Oxidation Pathway Intersects the TCA Cycle. The transformation of the chemical energy of fuel molecules into useful energy is strictly regulated, and several factors control the use of glucose, fatty acids, and amino acids by the different cells.

For instance, not all cells have the enzyme machinery and the proper cellular compartments to use all three fuel molecules. Red blood cells are devoid of mitochondria and are therefore unable to oxidize neither fatty acids nor amino acids, relying only on glucose for ATP synthesis. In addition, even in cells that can use all nutrients, the type of food substrate that is oxidized changes according to the physiological situation of the cell, such as the fed and fasting states.

Different signals dictate how cells can adapt to each situation, such as hormones, which may exert powerful effects by switching key enzyme activities in a matter of seconds, or how they may modulate gene expression profile, changing the whole cell metabolic profile. We must therefore understand all metabolic pathways as integrated events controlling energy regulation and conversion.

Your body uses energy all the time, even when you are resting. You need it to breathe, balance hormones , circulate blood, repair cells, grow new cells, and more. Therefore, finding natural ways to boost your metabolism is critical, not just for maintaining optimal weight.

Moreover, there are three different types of metabolisms. Knowing your metabolic type is the first step toward naturally boosting your metabolism.

There are three different metabolic types: ectomorphs, mesomorphs, and endomorphs. Understanding which type of metabolism you have is essential. Your metabolic type determines the most effective natural ways to boost your metabolism for optimal weight.

This metabolic type typically has a long, lean body with little fat and muscle. Ectomorphs struggle to put on weight because they have a naturally boosted metabolism, which allows them to burn calories much faster. If you fall into this category, you can probably eat anything and not gain a pound.

A diet with a high-calorie intake filled with healthy fats is ideal. Olive oil, avocado oils, wild-caught fish, fruits, and vegetables are a natural way to boost metabolism.

Mesomorph bodies are athletic, solid, and have well-defined characteristics. If you identify with this body type, you will want to watch your calorie intake.

That said, this body type has a much easier time losing weight than the other two types. These natural ways to boost metabolism can help Mesomorph types quickly shed pounds. Mesomorph body types require a balanced diet of carbohydrates, protein, and fat as natural ways to boost metabolism.

This type also benefits from a protein supplement to curb sugar cravings and promote a healthy metabolism. A large frame and a higher body fat percentage typically characterize this metabolic type. If you gain weight and muscle quickly and struggle to take it off, consider yourself this body type.

This body type has the slowest metabolism of the three metabolic types because it stores nutrients and energy efficiently. They have faster rates of fatigue since the body is less inclined to use the stored nutrients and energy. If you identify with this body type, I recommend a diet high in protein, healthy fats, and leafy greens.

In addition to a particular metabolic type, understanding your metabolic rate is also critical for naturally boosting your metabolism. As we mentioned earlier, Your body consistently burns calories, whether breathing, balancing hormones , circulating blood, producing cells, etc.

The number of calories your body uses is your Basal Metabolic Rate BMR. Several primary factors influence your metabolic rate, some of which point to natural ways to boost your metabolism.

The science behind weight loss starts with a calorie deficit. You see, calories do not control your metabolism — hormones do! The pancreas produces insulin to regulate blood glucose levels when they begin to rise.

It produces glucagon in response to low blood glucose levels. This is how your body breaks down carbohydrates and turns them into energy. One important reason is that the thyroid hormones thyroxine T4 and triiodothyronine T3 determine the basal metabolic rate. These hormones also regulate glucose.

The pituitary gland produces the thyroid stimulating hormone TSH that controls the release of T4 and T3 hormones from your thyroid.

However, if your thyroid is underactive, it ultimately slows down your metabolism and prevents you from losing weight.

Remember, your metabolism slows down naturally as you get older. However, measuring your metabolism is a very complex process. That said, there are certain warning signs that your metabolism has slowed down. Hypothyroidism is the most common form of thyroid disease and causes a general slowdown of your metabolic processes.

This is why those who lose significant amounts of weight in a short time end up putting the weight back on. The good news is that you can boost the production of your T3 and T4 hormone levels with exercise. The paradox is that you need to lower your calorie intake to lose weight.

When you reduce calorie intake, your body detects the loss. It responds by conserving calories by signaling your thyroid to slow down the release of T3 and T4 hormones. This slows your basal metabolism, making weight loss more difficult unless you find natural ways to boost your metabolism.

If your metabolism has slowed, reaching your optimal weight can be frustrating. But there are natural ways to boost your metabolism, empowering you to reverse that slow metabolism. These natural ways to boost metabolism will support a healthier metabolic rate!

It starts with two effective metabolism supplements — conjugated linoleic acid CLA and green tea extract. Linoleic acid is the most common omega-6 fatty acid. Trans fats reside in the hardened vegetable fats found in most baked goods such as margarine, butter, or ghee.

Natural trans fats are very different from industrial trans fats. CLA is a naturally occurring trans fat found in beef. However, there is no way to know how much CLA is in the beef you eat. The percentage of CLA varies greatly depending on farming techniques; it can be nearly impossible to get enough from diet alone.

CLA facilitates increased fat metabolism and improved lean muscle tone. Clinical evidence shows linoleic acid helps modulate the metabolism of fat, which helps your body utilize food for energy.

It has also been shown to support healthy levels of triglycerides in the bloodstream. In other words, it blocks your body from building fat stores.

By increasing fat metabolism, CLA helps your body burn more calories throughout the day, even at rest. An increased fat metabolism allows you to utilize energy more efficiently. It might be as simple as not getting enough conjugated linoleic acid. The good news is that you can supplement your diet with this game-changer as a natural way to boost your metabolism.

CLA is my first-ever clinically formulated metabolism supplement for healthy weight management. Green tea is primarily known for its antioxidant content due to its high levels of catechins.

Catechins are a powerful antioxidant found in berries, tea, and coca. Studies show that a cup of green tea significantly increases antioxidant production in your body. EGCG doubles as a free radical scavenger and fat burner.

This Green Tea extract is also among the natural ways to boost metabolism. EGCG is a powerful fat-burning accelerator that revs up your metabolism and boosts your energy levels.

However, green tea contains the toxic ingredient caffeine, so I recommend most people avoid it. What if I told you that you could get optimal amounts of EGCG without the harmful effects of caffeine?

I formulated a blend of botanicals, marine supernutrients that help your body burn fat cells, and EGCG from green tea extract without the caffeine for a metabolism supporter called LEAN.

The EGCG in LEAN influences the control center of your body: Your brain. The EGCG from the green tea extract works with the nutrients from the botanical blend and marine supernutrients to increase your serotonin levels.

Serotonin is the neurotransmitter responsible for controlling appetite. Moreover, LEAN is non-GMO, gluten-free, dairy-free, soy-free, paleo-friendly, and AIP-friendly.

In addition to these nutrients, I always recommend a high-quality protein powder as a natural way to boost metabolism. Protein curbs sugar cravings and promotes a healthy metabolism. What if there was a way to get all the benefits of protein, CLA, and LEAN all in one place?

What if you could achieve an optimal weight with natural ways to boost your metabolism? I also tackled my own stubborn weight gain problem. In addition to the game-changing supplements, this program includes other natural ways to boost your metabolism, like:.

I want you to continue to build on your success after you complete this groundbreaking program. You cannot slow down aging or do anything about genetics. But you can't entirely blame a sluggish metabolism for weight gain, says Dr. Is it possible to speed up a naturally slow metabolism, or rev up one that has become sluggish over time?

That, along with adopting a healthier diet and making sure you get enough exercise, may give people the extra push they need to lose and maintain weight.

Pick up the pace. Add some high-intensity interval training to your regular routine. After a period of interval training, your metabolism can stay revved up for as much as a full day.

For example, when you're walking or jogging on a treadmill or outside, speed up for 30 to 60 seconds, and then slow to your usual pace; repeat the cycle for eight to 12 minutes.

Eat protein and do weight training. Your metabolism increases whenever you eat, digest, and store food, a process called thermic effect of food. Protein has a higher thermic effect compared with fats and carbohydrates because it takes longer for your body to burn protein and absorb it.

It's not clear how much of an effect protein has on metabolism, but studies suggest the best approach is to combine adequate protein intake with weight training, which increases muscle mass — and that also can boost metabolism.

Drink green tea. Studies have found green tea contains a compound called epigallocatechin gallate, which may increase the calories and fat you burn.

A meta-analysis published in Obesity Reviews found that consuming about milligrams of epigallocatechin gallate the amount in about three cups of green tea helped boost metabolism enough to burn an average of extra calories a day.
