Conditions

  • Obesity and Overweight
  • Dietary Intervention

Interventions

BEHAVIORAL

Individualized dietary intervention

The participants will take a individualized dietary intervention guided by refined obesity phenotyping and based on digital management tools. Dietitians will use the decision tree algorithm of the digital management tool to first set the macronutrient ratios and dietary pattern recommendations based on ①metabolic health status and ②body composition characteristics, then set the eating rhythm recommendations based on ③emotional characteristics and ④individual behavioral characteristics，and then set the food recommendations based on ⑤dietary preferences.

BEHAVIORAL

Traditional energy-restricted balanced diet

The participants will take a traditional energy-restricted balanced diet based on the resting energy expenditure measured at baseline for each participant. A daily caloric deficit of 500 kcal was set for each individual. Dietitians provided dietary guidance plans and recommended sample menus in accordance with the traditional general dietary recommendations from the "Dietary Reference Intakes for Chinese Residents." The overall dietary principles emphasized a diet rich in whole grains, low in fat, with ample vegetables and fruits, and avoiding added sugars.
