How Can I Safely Get on a Liquid Diet?
First, talk to your doctor about whether a liquid diet is appropriate for you. Pregnant or nursing women, and people who take insulin for diabetes, shouldn't go on a liquid diet.
If your doctor gives you the OK to go on a liquid diet, you should also see a registered dietitian, who can go over the diet with you and make sure you're getting enough calories and nutrition. Your dietitian might recommend that you take a vitamin or nutritional supplement while you're on the liquid diet.
Before you choose a liquid diet plan, know what you're drinking. If you're considering one of the commercial diets, look at the daily values on the nutrition facts label. Be sure you're getting 100% of all the recommended vitamins and minerals.
You may also want to pick a diet that is not too low in calories and that lets you lose the weight gradually. Liquid diets that include a solid meal or two per day, or that teach you healthier eating habits, will be more likely to help you keep the weight off in the long run.
