See the balance pointer go up in the cold season not always the blame is only the hot chocolate

The chill is not very exciting for a walk by the sea, but do not escape the winter sun. The lack of light and heat on the skin helps you gain weight at this time of year, according to a study by the University of Alberta, Canada. Saw? It is not always the fault of hot chocolate .

“There is still no consensus, but it is known that the lack of vitamin D , which is activated by sunlight, is linked to the increase in body fat, ” says Maria Edna de Melo, president of the Department of Obesity of the Brazilian Society of Endocrinology and Metabology (Sbem).

Not only that, because on cold days the period of luminosity is shorter, the circadian cycle, which controls ghrelin and leptin ( hormones responsible for the sensation of hunger and satiety , respectively), is altered – hence that extra hunger typical of winter. Then nothing to waste the time of the gym to stay five more minutes under the covers.
