Sticking to a very low calorie diet long-term can also lead to nutritional deficiencies. Your body needs certain nutrients for optimal function. This can lead to numerous other issues. For example, research has linked deficiencies in iron, copper, and zinc with hair loss.

Deficiencies can also lead to poorer gut health. Gut health is important for the brain while also helping to protect against chronic disease. So, the effects of too quick weight loss are many and can change depending on what your diet looks like and how long you stick to this type of plan.

This requires employing sustainable weight loss strategies consistent with a healthy lifestyle. Here are a few to consider:.

Eat enough calories to meet your nutritional needs. If you or your client are not sure what these needs are, working with a nutritionist can help. Certain people have different nutritional requirements.

They can change when pregnant or breastfeeding, for instance. They also change based on the stage of life, with some varying quite drastically based on whether the person is a teen, adult, or older adult. Consume foods from each food group.

One common theme among quick weight loss diets is that many omit entire categories of food. This is how deficiencies can start to form. Your diet should include carbs, protein, and fat. The key is to choose healthy versions of each. For instance, sources of healthy fat include avocado, olive oil, nuts, and seeds.

Whole grains and fruit are healthy carbs while lean meats, fish, and eggs are each a source of healthy protein. Choose natural over processed foods.

Some diet plans consist primarily of pre-packaged or processed foods. This means that they contain other substances that might not be good for your health—even if they are within the dietary guidelines.

Natural food sources are best. Develop healthy eating habits. Do you tend to eat while standing at the cupboard or refrigerator? Are you usually the first one done with your meal? Making small changes to eating habits such as these can help with weight loss. Avoid fad or crash diets.

Remember that these diet types are intended to be short-term. While that means maintaining a balance, opting for moderation in your food choices, and exercising, it also means quitting diet culture and possibly resetting your relationship with yourself.

Before you start any weight loss journey, dig deep to find your real motivation behind your desires. If the reason is temporary, such as fitting into an old dress for an upcoming event, would getting a new outfit fit your budget instead?

If you notice a sudden drop in weight in just three days, watch out for signs of dehydration such as headaches, fatigue, low energy, and irritability as you are most likely just losing your water weight. When talking about healthy weight loss, the main goal is to get rid of the nasty stored fat tissue instead of muscle mass that gives us a toned look. This can be achieved through slow and conventional weight loss methods combined with regular exercise as it allows the body to build muscle mass while burning more calories and fat. However, sudden and highly restrictive diets can trigger the body to break down muscle proteins for energy rather than using fat stores. This is one reason why you instantly lose so much weight during the first few days of a crash diet. Many studies have shown that you lose three times more lean body mass when you undergo rapid weight loss than you would if you took a slower and more sustainable strategy. When you deprive yourself of your ideal calorie intake, your body attempts to conserve energy by decreasing the rate of calories being burned while walking, eating, sleeping, and exercising. While you can drop off a lot of weight during the first few days of an extreme diet, your body will eventually struggle to burn calories and you will reach a weight loss plateau even when you strictly follow the diet. This will set you up for weight cycling where you lose weight and gain it again quickly once you go back to your prior eating and lifestyle activities. This might be a bit obvious, but when you go on 1,calorie per day diets, the hormone that regulates hunger and satiety called leptin gets really unstable. At normal levels, it signals your brain that you are full when you have enough fat in your body. However, in a lower-calorie diet, the body tends to have unbalanced leptin levels, which causes you to feel hungrier than usual and more likely to overeat during your next meal. Many quick-fix and extreme diets are usually based on eliminating entire food groups or carbohydrates, which can be quite problematic from a nutritional standpoint. In order for your body to function properly, you need to consume certain amounts of protein, fats, and carbs, as well as a wide range of essential nutrients like vitamins and minerals. While you might be able to lose fat quickly, it can also lead to an increased risk of developing serious health conditions. While there are lots of ways to approach your weight loss problems, taking on an extreme weight loss diet as a quick fix is not an ideal solution to achieve a sustainable weight. In fact, it can even set you up for weight regain soon after and it can be dangerous for your physical and mental health in the long run. With proper diet, regular exercise, and the right amount of focus and discipline, losing weight in a short amount of time is within reach without putting your health at risk. However, the real and bigger challenge for most people is keeping the weight off over the long term. At Beltline Health, we work with thousands of people who struggle with their weight by providing surgical and non-surgical weight loss solutions to help them take control of their life.
