Study Arms:
- CHH-diet arm (Type: EXPERIMENTAL): During the 4-week intervention period, free meals conformed to CHH-diet will be provided 3 times per daily (breakfast, lunch, dinner). Different center offers different meals of different cuisines but all conformed to CHH-diet. The main nutrientional healthy goal of different cuisines will be achieved through specific nutrient targets, including fat, carbohydrate, protein, dietary fiber, sodium, potassium, magnesium and calcium.
- local usual diet arm (Type: OTHER): During the 4-week intervention period, three meals per day (breakfast, lunch, dinner) will be provided free of charge in line with local dietary characteristics. The energy,protein, carbohydrate, as week as dietary fiber, sodium, calcium, magnesium and potassium will be kept the same as that in the run-in phase.

Based on this trial design, predict the completion outcome and termination type (if applicable).
