Description as written by the study sponsor.
In patients initiating Semaglutide for weight management, the objective is to compare the effect of the Mediterranean diet and the high protein/low carbohydrate (HP/LC) diet CV parameters, namely arterial stiffness, measured by carotid-femoral pulse wave velocity (cfPWV), and visceral adipose tissue, in addition to other metabolic indicators.
Treatments tested
- Dietary Intervention Med Diet Other
The diet will consist of a calorie-restricted Med diet, with 500 Kcal/d energy restriction. The intervention consists of individual and reinforcement sessions on Med diet. During these sessions, the RA will go over the benefits of Med diet, what composition it should have, and how to make appropriate choices for meal planning, in addition to providing food lists, by season. The individual sessions with subjects will also allow to individualize the diet plan.
- Dietary Intervention HP/LC Diet Other
This is a non-ketogenic diet consisting of ad libitum intake of proteins, fat, and vegetables, with restriction of daily carbohydrates to \<130 g/d. The intervention consists of individual and reinforcement educational sessions on HP/LC, same as with Med diet (above). The individual sessions with subjects will also allow to individualize the diet plan.
