Exercise every day or even three to four times a week, perhaps for more than an hour; try to eat properly, yet nothing to do, the scale does not drop by a pound, on the contrary, sometimes after a few promising leaps down, the next day you are an extra pound or two. What does it mean? Has the scale gone crazy? Are you on the wrong diet? Here’s everything I know from my experience about diets and sports and why dieting and exercising doesn’t necessarily lead to weight loss. As you will notice, I have divided this article into two for clarity: 1) Why I don’t lose weight despite my diet; 2) Because I don’t lose weight despite sport (you can find it in this other article).

WHY I DON’T LOSE WEIGHT DESPITE THE DIET
1) The ideal diet is the one that always allows you to burn more than you eat: every diet must be based on this very simple but fundamental calculation, so even if around you will find many diets that recommend you to being able to eat to your fill, the diet is explicitly or not a form of calorie or food restriction. If the diet you have chosen has a calorie restriction, is low calorie or with a maximum calorie limit; if the diet is on food restriction, you don’t have a calorie ceiling, but you can’t eat certain categories of foods, which in any case means that you automatically eat less. In both cases the body can resist weight loss:in the first case, if you have done so many diets, you have already accustomed your body to making the little you give it enough, which is why you do not lose weight. To lose weight, you should aim to speed up your metabolism. In the second case, depriving yourself of certain categories of foods does not necessarily mean that you have to lose weight. You will find many cases of people who by depriving themselves of carbohydrates have not lost a pound.
2) The fact that the diet you have chosen has made many people lose weight does not mean that it will necessarily make you lose weight too.The problem with many current diets is that they look like the work of a group of marketers rather than being developed by a dietician. They tell you that if you buy the book and do the x diet you will lose weight like ninety percent of those who have done it, making you feel like the only fool who has not made it. Instead, there are many people who have not lost weight with that diet, but certainly no one will come to tell you. 
3) Don’t panic:with each modification of the diet, the amount of water you retain changes, the intestinal microbiota or flora changes, and the metabolism also changes little by little. However, every body is different, and the reaction to a change in diet is always unexpected. You can have a variation of up to three or four kilos more or less due to the fact that you lose or retain a lot of water, and since this water is retained at the cellular level, you have to wait a few days or even a week or two to understand if you are or not on the right track. You are on the right track if the diet starts to give you benefits in terms of less bloating, for example, energy, sometimes even mood: the weight will drop over time. You are well on your way if the diet matches the criteria that many dieticians or people of science would approve of.
