When You Eat and Weight Loss in Mediterranean Adults

Researchers believe that *when* you eat may be just as important as *what* you eat for weight loss. This trial is examining whether eating your main meal (lunch) earlier in the day—rather than late—helps people lose weight more successfully and improves metabolic health. The study also looks at whether certain genetic variations affect how meal timing influences your body's ability to manage blood sugar and lose weight.

Obesity and related metabolic problems are major health challenges, but standard weight loss advice often focuses only on food choices and amounts. Recent evidence suggests that meal timing—particularly eating late in the evening—may actually interfere with weight loss and blood sugar control. This trial aims to understand these timing effects so doctors can develop more personalized, effective weight loss plans.
