Nearly 80% of the population in France is deficient in vitamin D. However, “supplementation in people with a deficit makes it possible to restore certain metabolic mechanisms in working order without which it is very difficult to lose weight”, indicates Dr Didier Chos. It is therefore not surprising that when a deficiency persists, it is difficult to lose weight,” he says.
And “we also know that this deficiency is more pronounced in overweight or obese people,” he adds.
A syndrome generally observed in sedentary people
Thus, there are vitamin D receptors all around the adipocyte cells, specialized in the storage of lipids, and therefore fat. “It also probably plays a modulating role in insulin resistance,” continues Didier Chos.
This syndrome is observed particularly in sedentary, overweight subjects. However, “supplementation makes it possible to restore the metabolic mechanisms without which it is very difficult to lose weight”.
However, “this is not to say that vitamin D supplementation is the solution to make everyone lose a few pounds,” he warns.
