Summary

This study looks at how a personalized, calorie-restricted diet affects metabolism in overweight or obese Chinese adults. Researchers will measure how the body uses energy before and after a 12-week diet plan. The goal is to understand why people respond differently to the same diet and to predict who will lose the most weight.
