1, 1, and 3-day heavy liquid break are clear conclusions: 1, 3-day heavy liquid break is a common method to lose weight, but 3-day heavy liquid break is more challenging than 1 day heavy liquid break, which can lose weight more effectively, but it will also bring greater physical burden and side effects.

2. The main difference between these two methods lies in the length of time. 1 day liquid fasting refers to a diet in which only liquid food is consumed all day and solid food is completely avoided, while three days of liquid fasting can make the body consume very little calories and nutrients for three consecutive days, mainly taking liquid diet.

3. Weaning for 3 days is more challenging, which requires full psychological preparation and physical adaptation. However, compared with 1 day weaning, 3-day weaning can lose weight more effectively, remove excessive toxins and wastes from the body, and make the body enter the state of "hunger therapy", thus achieving a rapid, efficient and healthy slimming effect.
