A Randomized Study to Investigate the Effect of a Low-calorie and High-protein Diet Specially Rich in Animal Protein Compared to a Low-calorie and High-protein Diet Specially Rich in Plant Protein on Glucose Metabolism in Subjects With Prediabetes or Type 2 Diabetes and Overweight or Obesity.
A Randomized Study to Investigate the Effect of a Low-calorie and High-protein Diet Specially Rich in Animal Protein Compared to a Low-calorie and High-protein Diet Specially Rich in Plant Protein on Glucose Metabolism in Subjects With Prediabetes or Type 2 Diabetes and Overweight or Obesity.
The aim of the study is to explore the effect of a low-calorie diet rich in protein (with a content of 35% of the total calories of the diet), mostly coming from animal sources (75% of total protein), compared to a hypocaloric diet rich in protein (with a content of 35% of the total calories of the diet), mostly coming from plant sources (75% of total proteins), in subjects with prediabetes or type 2 diabetes and overweight or obesity, on body composition, glucose and lipid metabolisms, after 6 months of intervention.
To achieve the objective, a nutritional intervention study is carried out by randomizing participants to: a) a hypocaloric and high-protein diet (35% of total calories), mostly of them coming from animal sources (75% of total protein); b) a hypocaloric and high-protein diet (35% of total calories), mostly of them coming from plant sources (75% of total protein). The study has a total duration of 6 months and include the assessment of clinical, anthropometric, biochemical and lifestyle parameters, at the beginning of the study and after 3 and 6 months of intervention.
