Milk shake meal replacement, it is enough for you to have two meals and milk shake besides three meals a day, regardless of any time period, but I suggest you replace meals in the morning and evening. It's convenient to drink milkshake in the morning, so you don't have to make breakfast. In addition, drinking milkshakes in the morning is easily absorbed by the intestines. Eat whatever you want in Chinese food, just eat seven points full, and then drink milkshake at night. This arrangement is the most reasonable. If you want to lose weight, you'd better not eat dinner at night!
