Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this intervention study was to evaluate in type 2 diabetic patients the effects on postprandial lipemia and other metabolic parameters (in both everyday life conditions and after a standard test meal) of two diets, one moderately rich in CHO, rich in fibre and with a low glycemic index (Mediterranean diet), and the other low in CHO and rich in MUFA (Low-CHO diet).Since adipose tissue, mainly through its lipolytic activities, is considered as having a pivotal role in the regulation of postprandial lipid metabolism, a further aim of our study was to clarify the role of adipose tissue in modulating the postprandial lipid response induced by the two dietary approaches by evaluating the activities of lipoprotein lipase (LPL) and hormone-sensitive lipase (HSL).

Mediterranean diet and Low-Carbohydrates diet

Intervention Type OTHER

The Mediterranean diet: relatively rich in Carbohydrate(52% of the total daily energy intake), rich in dietary fibre (28g/1000 kcal both of soluble and unsoluble types) and with a low glycemic index (51%) versus Low-carbohydrates diet : diet rich in MUFA (23%), relatively low in CHO (45%), low in dietary fibre (8g/1000 kcal) and with a relatively high glycemic index (87%)for 4 weeks
