Top 6 Biggest Disadvantages of Extreme Diets


Extreme diets offer restrictive and dangerous eating plans. Even if they make you lose weight quickly, they cause side effects that can reduce your quality of life.

Extreme diets have gained popularity around the world, seen as a “quick” way to lose weight in a matter of days. These are restrictive eating plans that suddenly decrease the total daily calories, bypassing the nutritional needs of our body.

The results given are almost “miraculous” and that is why many people make the decision to adopt them. The downside is that these are diets that force our body to exceed its limits, causing it to have a series of adverse reactions.

In addition, the majority of these plans produce the famous “yoyo effect”, and it is for this reason that many fail by wanting to lose weight quickly and in an unsafe manner.

What are the risks of extreme diets? Even though many prefer to ignore it, this variety of dietary programs shows disadvantages that endanger our health in many aspects. Discover them!

The disadvantages of extreme diets that we all need to know

The majority of people interested in an extreme diet have put on weight due to excess food. Eager to regain their previous figure, they opt for these plans that promise results in a few days or a few weeks.

This does not mean that all diets are bad. However, if you want to lose weight, it is better to choose the options that offer a balanced diet full of nutrients.

When these criteria are not met, weight loss can be linked to poor nutrition or illness. Therefore, even if they make you lose weight, these are diets that are not recommended by any nutrition expert. Here are some of their disadvantages:

1. They can produce hypoglycemia

People who go on a diet that has to endure hunger are likely to suffer from an episode of hypoglycemia. Whether it is because they do not eat, or because they take food substitutes.

In addition, the cells do not get the fuel required to work in optimal conditions, which causes states of fatigue and weakness.

2. They increase cholesterol levels

When extreme diets are based on the consumption of meats and proteins,  the risk of suffering from problems due to high cholesterol in the blood is increased. This is also why many patients end up having problems with pain in the joints.

Even if the body has the capacity to digest proteins, an excessive amount can overload its functions. One of the consequences is an increase in lipids in the blood, which increases the risk of serious cardiovascular disease.

3. They cause digestive problems

While some extreme diets lead to the development of constipation and problems in the colon, others produce episodes of diarrhea and dehydration. The diet can be deficient in dietary fiber, a key nutrient for digestion.

In addition, when it contains too much fiber and water, as is the case with the diet based on fruits and vegetables, it can cause abdominal cramps and watery, loose stools.

4. They produce the yoyo effect

The body responds to any type of restrictive diet and, therefore, it is normal to lose weight. But once regular eating habits are restored, the body, in response to the change, causes the famous yoyo effect.

As a result, the feeling of anxiety about food increases, as does the tendency to accumulate fat in various parts of the body. It is for this reason that many quickly regain their lost weight.

5. They affect your immune system

A sudden change in diet and restriction of essential nutritional foods can significantly affect immune health. Often, those who go on extreme diets are more prone to suffer from infections and illnesses.

When the body is not physically prepared, it exhausts its natural antibiotics to replace the minerals it does not receive. So weaken our defenses and antigens can attack tissues without difficulty.

6. They produce metabolic disorders

Extreme diets that offer to completely eliminate a group of nutrients can lead to metabolic disorders. By limiting for example carbohydrates and fats, the activity of the metabolism will suffer from the change.

As a result, many functions of the vital organs are impaired and symptoms and ailments occur which can affect the quality of life when they are not controlled in time. Some of them include:

  • Type 2 diabetes
  • Loss of muscle mass
  • Hyper or hypothyroidism
  • dyslipidemia
  • Liver conditions

Want to lose weight without exposing your health? Instead of adopting extreme diets, choose a complete diet plan that fits your needs. Even if the results take a little longer to arrive, they are safer and permanent.
