Overweight and fat are national obsessions in the US, where 2/3 of Americans are obese, but it starts to become also in other countries.
Thought wrongly that when it grows is due to a too low metabolism, yo-yo diets, insufficient meals and poor distribution of calories, excess carbohydrates or too great assimilation: 'everything is benefiting me '...
In fact, none of this is true. According to scientist Claude Bouchard of the Pennington Biomedical Research Center in Louisiana, there are 5 real reasons which may justify weight:
1) a lack of muscle mass which slows down metabolism
2) a bad physical condition that limits the ability to spend calories
3) low levels of testosterone which prevents ' manufacture ' muscle
4) insensitive to leptin (, which disrupts appetite and metabolism
5) an inability to burn fat, resulting in a greater propensity to store them.
