If we lived in an ideal world, playing sports would be enough to make us lose weight. After all, physical activity helps burn calories, and thus use our internal energy reserves, fat. But the human metabolisms are not always fair and logical. Numerous studies have shown that most people who start a new exercise routine lose only 30-40% of the weight they thought they could lose.
So far, researchers have not established the real reason why we also poorly compensate for the beneficial effect of sport. So for a new study published by theAmerican Journal of Clinical Nutrition and cited by the New York Times, US researchers asked a large group of inactive people to exercise. The team recruited 171 sedentary, overweight men and women between the ages of 18 and 65. They then recorded data regarding their weight, resting metabolism, hunger level, aerobic fitness, daily food intake and energy expenditure.
The volunteers were then randomly assigned to three groups: a control group, a supervised exercise group to burn about 700 calories per week, and another to lose about 1,760 calories per week. The volunteers could eat however they liked. After six months, they all returned to the lab to update their data.
As expected, people in the control group did not change weight or resting metabolism. Among those from sports groups, only a few have lost the expected pounds. Two-thirds of those in the 700 calorie group and 90% of those in the 1,760 calories group were disappointed because they did not lose the expected weight. They had compensated for their calorie expenditure additional.
Conclusion: people who exercised ate more. The extra calories were small, but enough to reduce weight loss. Only a few athletes who avoided snacking too much and falling for junk food lost weight. Sport, therefore, remains a tool to find the line only if it is accompanied by a balanced diet.

What are the possible causes?
There are several of them. If the needle of the scale does not drop in the first few days, it is undoubtedly because the body is adapting, not only to new eating habits but in addition to a (re) discovery of physical activity.
In addition, there is a possible link between physical activity and brief water retention (an intense effort could damage the structure of the tissues and cause, consequently, this temporary and temporary increase in water retention) and therefore weight gain. A completely normal process that should subside as the days go by.
However, even in the face of a slight discouragement, it is essential to show patience and perseverance: if the weight does not drop, you should look at your mirror more than at your bathroom scale. Sport often changes the silhouette more than the pounds …
