Studying How Low Activity and Added Sugars Affect Insulin and Metabolism in Active Young Adults Aged 18 to 30

What this Trial Is About

This research aims to understand changes in insulin resistance and the bodys ability to use fat and carbohydrates when healthy young men and women shift to an obesogenic lifestyle. The study focuses on whether adding excess carbohydrates while becoming less active affects insulin resistance, glucose control, and the bodys fat-burning ability. It also evaluates if increased physical activity can reduce these effects in recreationally active young adults aged 18 to 30. Participants will be randomly assigned to one of four groups for 10 days a low physical activity group consuming added sugar-sweetened beverages, a low physical activity group without added sugars, a high physical activity group with added sugars, or a control group maintaining normal activity and exercise. The study uses behavioral interventions to test how changes in activity levels and carbohydrate intake impact metabolic health. During the study, participants will undergo assessments to measure insulin resistance, 24-hour glucose regulation, and fat oxidation. Researchers will monitor physical activity using step counts and track dietary intake. The primary outcomes will be evaluated after the 10-day intervention to determine how these lifestyle changes influence metabolic function. The study includes healthy recreationally active adults and involves no blinding.
