Twins on a diet: can genes predict weight loss success?
NCT ID NCT07362550
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study in Lahore, Pakistan, is recruiting 60 healthy twins to see how genetics and environment influence the effects of a balanced diet. Over 12 weeks, both identical and fraternal twins will follow a WHO-aligned diet. Researchers will measure changes in body fat, blood sugar, and cholesterol to understand why some people respond better to diet changes than others.
