What this trial studies
This study evaluates the effectiveness of a low-calorie, low-protein diet supplemented with essential amino acids (EAA) in patients with high-grade obesity. Participants aged 45 to 65 will be randomly assigned to either an EAA supplement group or a placebo group while following the diet. The primary outcomes measured after two weeks will include weight loss and maintenance of muscle mass. The study aims to determine if the EAA supplementation enhances the weight loss effects compared to a standard diet.
Why it matters
Potential benefit: If successful, this approach could improve weight loss outcomes and muscle preservation in obese patients.
How similar studies have gone: Previous studies have shown positive effects of amino acid supplementation in weight loss, suggesting potential success for this approach.
