NCT05783466

Brief Summary

It is a randomized parallel arm intervention study in adults with severe obesity. The objective is to demonstrate that within a dietary handling for weight loss, the daily ingestion during 3 months of whole dairy products enriched with milk polar lipids or whole dairy products decreases to a greater extent fasting plasma apolipoprotein B concentrations than the daily ingestion of low-fat dairy products (control group). Metabolic parameters will be assessed before and after the 3-month intervention, both at fasting and in postprandial period after the consumption of standardized meals.
