Some weight-loss centers provide strict recipes, for example, allowing only chicken poached in clear water, or raw tomatoes with boiled eggs, and so on. If these foods are not too troublesome to make, they're too unappealing to eat, and there's just no way to stick to the regimen for long.
有些瘦身中心提供嚴苛的食譜，譬如每餐只能吃清水煮的雞絲，或是生番茄加白水煮蛋等等，不是太麻煩，就是太難吃，根本不可能長期遵守。
