Effect of a Carbohydrate-rich Diet in Healthy Subjects

The present research protocol will analyze whether a short‐term modification (one week) of dietary habits would have an impact on the postprandial metabolism of dietary fatty acids and on their uptake by non‐adipose tissues, in healthy subjects. Each subject will participate in two protocols randomly determined and separated by a period of one month: a 7‐day isocaloric diet (Protocol A) and a 7‐day carbohydrate‐rich diet containing +50% of the subject's energy needs. (Protocol B). At the end of each diet, the subject will go through a postprandial metabolic study of 8 hours where different parameters will be measured thanks to PET imaging and perfusions of stables isotopes.
