Study of Twice Daily Whey Protein Intake to Improve Blood Sugar Control in Adults Aged 50 to 70 with Prediabetes or Type 2 Diabetes

What this Trial Is About

Researchers are evaluating how twice daily consumption of whey protein affects blood glucose and insulin levels in people with prediabetes and diabetes. The study aims to understand how whey protein taken in the morning and before dinner influences appetite, carbohydrate intake, and glucose control over a week. This research focuses on adults aged 50 to 70 with specific blood sugar levels to explore differences between prediabetic and diabetic participants. Participants will take part in a randomized, triple-blind crossover study involving one week of whey protein isolate supplementation and one week of a placebo supplement. They will consume the whey protein within one hour of waking and 30 minutes before dinner to test its effects on appetite suppression and glucose metabolism. This design allows each participant to experience both the protein and placebo periods. During the study, participants will be asked to maintain detailed food journals and wear continuous glucose monitors for two separate 7-day periods. Researchers will measure whole body protein turnover, oral glucose tolerance, blood glucose levels, appetite, and dietary intake. The study includes careful monitoring of insulin response and carbohydrate intake to assess changes over the treatment periods.
