Description for medicine or protocol of treatment in detail: |
This is a prospective stratified randomized study. Participants will be randomly assigned to one of three groups: (1) High-quality Low-Carbohydrate Diet group (hLCD); (2) 8-hour Time-Restricted Eating group (8-h TRE); (3) High-quality LCD + 8-hour Time-Restricted Eating group (hLCD+8-h TRE). Each group will include 55 participants. The intervention period will last 12 weeks, followed by a 12-month follow-up period after the intervention ends. The detailed study protocols for each group are as follows: (1) High-quality Low-Carbohydrate Diet group (hLCD): Meals are consumed within three conventional meal times, with the last meal finished by 19:00. Macronutrient distribution: 27% carbohydrates, 30% protein, 43% fat. - Breakfast: Whole grain powder (1 stick, 16g) + reference recipes. - Lunch: Reference recipes. - Dinner: Composite dietary fiber powder (1.5 sticks, 18g) + meal replacement powder (1 stick, 30g) + fish balls (1 pack, 60g) + reference recipes. (2) 8-hour Time-Restricted Eating group (8-h TRE): ≥85% of total daily energy intake is consumed between 07:30 and 15:30; the remaining energy must be consumed between 15:30 and 17:00 on the same day. Macronutrient distribution: 55% carbohydrates, 20% protein, 25% fat. - Breakfast: Reference recipes. - Morning snack: Composite dietary fiber powder (1.5 sticks, 18g). - Lunch: Reference recipes. - Dinner: Meal replacement powder (1 stick, 30g) + fish balls (1 pack, 60g) + reference recipes. (3) High-quality LCD + 8-hour Time-Restricted Eating group (hLCD+8-h TRE): ≥85% of total daily energy intake is consumed between 07:30 and 15:30; the remaining energy must be consumed between 15:30 and 17:00 on the same day. Macronutrient distribution: 27% carbohydrates, 30% protein, 43% fat. - Breakfast: Whole grain powder (1 stick, 16g) + reference recipes. - Morning snack: Composite dietary fiber powder (1.5 sticks, 18g). - Lunch: Reference recipes. - Dinner: Meal replacement powder (1 stick, 30g) + fish balls (1.5 packs for men, 90g; 1 pack for women, 60g) + reference recipes. |
