As the expert assures, being on a diet and losing weight does not always damage your metabolism. Through the body’s adaptations that occur in response to fat loss (actually to prevent loss), energy expenditure will be substantially less for those who have lost weight than for those who have always been lean.

Weight loss and weight retention are accompanied by adaptive changes in metabolism. These changes mean that we will use less energy.
The more we lose weight, the less energy we spend. And the more we rest and lie down, the less energy we have for training. And this variation can be up to 15% of the total metabolism,
says the nutritionist.

So, through the adaptive response of the body, a person who has lost weight will need 5 to 15% fewer calories per day to maintain weight at a level than a person who has always had this weight. This means that those who have never been overweight need, for example, 2000 kilocalories to maintain weight, and those who have already lost weight to the same level need a little less (1700 – 1800 kilocalories). This difference can last up to 7 years after weight loss or more.
