Nutritionist Kellyann Petrucci’s Grapefruit Diet, presented by Dr Oz Show, is a detoxifying regimen that revisits the lightning regimen known as the grapefruit diet in a more balanced and healthy way. This regime would in fact allow you to lose up to 1/2 kilo a day, taking advantage of the action of this citrus fruit that contains nootkatone , a chemical compound that has in fact been the focus of various studies in recent years, which would naturally stimulate the metabolism by activating the ‘AMPK, an enzyme that regulates the body’s energy homeostasis. In fact, compared to many “fad diets” the grapefruit diet is probably a very effective diet for stimulating metabolism ( source of a study ).
For this reason, even if personally I do not like single-issue diets and lightning regimes, this diet seems to me of particular interest.
