Frequently Asked Questions
How much weight can you lose on a 7-day liquid diet?
Most people lose 3 to 10 pounds during a 7-day liquid diet. However, the majority of that loss is water and glycogen, not body fat. Realistic fat loss over one week is only 1 to 2 pounds, since losing a pound of fat requires a cumulative deficit of about 3,500 calories.
Is a liquid diet safe for weight loss?
Short-term liquid diets of a few days are generally safe for healthy adults, but diets under 800 calories per day should only be followed under medical supervision. Risks include nutrient deficiencies, muscle loss, fatigue, and gallstone formation from rapid weight loss.
Do you gain the weight back after a liquid diet?
Yes, most people regain the weight quickly. A meta-analysis in Obesity found that very low calorie diets produced 16 percent initial weight loss but only 6 percent long-term loss, comparable to standard diets. The water weight lost in the first week returns almost immediately once normal eating resumes.
What is the difference between a clear and a full liquid diet?
A clear liquid diet includes only transparent fluids like broth, clear juice, and gelatin. A full liquid diet adds opaque liquids such as milk, smoothies, cream soups, and protein shakes. Full liquid diets provide more calories and nutrients and are more sustainable beyond a day or two.
