I have used this coffee before, and I have insomnia, which affects my work and rest. I'm useless anyway. Actually, it doesn't take two or three days to lose weight. I still have to put my diet on the agenda, not to mention dieting, which needs to last for a month, two months or even longer. It's not a meal replacement either, because I get tired of eating it soon, and even feel like vomiting when I see it. I pay attention to eating and drinking now, and I have lost 8 pounds in a month. I read Zhou Xinlei's method, and she kept a diary. It doesn't mean that I should try to eat low-sugar and low-salt food at all times. In the afternoon, you can eat some sweet fruit or yogurt and only drink skim or low-fat milk. Try to eat whole wheat bread, pasta and brown rice for breakfast. Try to prepare fresh vegetables or salads, such as a cup of sugar-free hot water+no more than 60-100g milk+whole wheat bread (both wheat and rye are acceptable) and half-boiled eggs! Friendly reminder, the weight of an egg is almost 50g!
