Conditions
Interventions
whey protein powder
The intervention period lasted for 12 weeks. During this time, Participants received dietary guidance from researchers. The whey protein group underwent a 30% energy reduction diet with a macronutrient distribution of 45%-50% carbohydrates, 30% fat, and 20%-25% protein. Participants consumed 13 grams of whey protein powder twice daily, with breakfast and afternoon snacks, partially replacing staple foods.
calorie-restricted balanced diet
The intervention period lasted for 12 weeks. During this time, Participants received dietary guidance from researchers. The calorie-restricted balanced diet group underwent a 30% energy reduction diet with a macronutrient distribution of 55% carbohydrates, 30% fat, and 15% protein.
health education
The intervention period lasted for 12 weeks. During this time, Participants received dietary guidance from researchers. The health education control diet group followed an unrestricted energy healthy diet plan with a macronutrient distribution of 50% -65%carbohydrates, 20%-30% fat, and 10%-15% protein.
