How much weight to lose in a week to maintain the lost weight afterwards? A new study confirms the idea that it is better to lose little weight, especially in the first weeks of the diet, in order not to see the results disappear at the end of the diet, and therefore risk regaining the weight from the maintenance phase.
To be exact, the experts of the  Drexel University of Philadelphia argue that to be able to not regain the weight lost with the interests (that is, gaining even a few more kilos compared to the initial weight before the diet) it would be necessary to lose weight in a week at most half a kilo. at a time. To establish this, the scientists followed a group of 200 people who had been on a diet for three years in a row.discovering that two thirds of these people have regained the weight they lost, even with a few extra pounds, after the diet. The third of the group who saved himself, maintaining the results of the diet with maintenance, was the one who lost a little weight at a time, or about half a kilo per week.
The possible reasons why losing little weight consistently is better than losing a lot of it all at once, for example with some drastic and fast diet, can be explained as a consequence of both hormonal variations and the psychological effects that occur during the diet.

On the one hand, in fact, the body has more time to adapt to changes in weight loss , while often those who lose a lot of weight very quickly witness a problematic slowdown in metabolism, an increase in hunger due to the decrease in leptin and others. hormones regulated by the hypothalamus and intestines. On the other hand, fast diets are often drastic, and therefore very stressful. Stress makes the peaceful continuation of the diet problematic, and is often responsible for phenomena such as binges, nervous hunger, change of diet, etc.
In short, the best diet is the one that provides for a slight calorie deficit, which can be obtained by eating 80% of the time in a healthier way and in moderation., and providing a small daily sgarro of about 100 or 150 calories even if not really healthy, like two biscuits or half a bag of chips (ie 25 grams). At the same time, this small deficit allows those who follow the diet to be able to move more, have enough energy to fight a sedentary lifestyle, thus ensuring greater weight loss in the long term ( source ).
