But in short, why do these doctors keep telling us that crash diets that allow us to lose weight quickly and improve our weight for at least two weeks are bad for us?
Won’t it all be a mega-conspiracy of doctors, pharmaceutical companies and associations?
Isn’t it that they make money by keeping us obese?
What then, if I can lose weight quickly, like a kilo a day, who are they to tell me it’s not done?
What do these doctors know about my health? Why are they bad?

Well, if at least one of these questions jumped into your mind reading about people who lost weight quickly and the photos on social media are a fairy tale, then go ahead and do your drastic diets.

However, if you suspect that losing weight quickly hurts, that without changing your life you will regain the lost weight and that among the many nonsense that you hear, what you find in the glossy magazine could be yet another, then I will help you in the exercise of doubt with this item.

According to a German study that evaluated the consequences of drastic diets, discussed at the European Congress on Obesity, losing weight quickly leads to a loss of water and muscle mass and a minimal loss of fat mass. This regardless of the regime chosen.

Even if the weight goes down, the pounds aren’t all the same, the researchers explained.
So at the end of the diet, between calorie restriction and loss of lean mass, I will have a slower metabolism than I started it. Resulting in weight gain

Why does the body get rid of lean mass first and not fat?

On a crash diet, the body gets the glycogen and other substances it needs from lean mass, after depleting the liver glycogen resources.
When dieticians talk about apparent weight loss they say just that.
Muscles weigh more than fat, if muscles and water go away the scales go down, fat mostly remains.

What the German study on rapid weight loss says.

By dividing two samples of people and subjecting one sample to a fast weight loss diet and a second a balanced but non-restrictive low-calorie diet, the researchers found that the first group lost weight in less time, but more muscle mass.
With the terrible consequence that he will regain weight, but as extra fat, and in the long run he will be fatter than when he started the diet.

The second group experienced slower weight loss but with more fat loss and less lean.

These are facts. There are also other studies that explain the same thing and more.
According to, for example , the theory of the weight settling point , the body “resists” rapid weight loss, trying to return to the conditions of the initial weight. How? With greater hunger, for example. Or more laziness, so we feel tired and burn less energy. The body gradually adapts to changes in weight. The slower these are, the fewer the problems.

This is why losing weight quickly hurts, or more than a kilo a week: because it is a deception that is bad for your health.
