![]() Meal replacements help lower blood fat levels because they usually provide all the healthy essential fats you need without additional or unhealthy fats, such as saturated or trans fats.Ī study in obese women shows that partial meal replacement significantly lowers blood fats compared to a standard very-low-calorie diet.įurther studies show that partial liquid meal replacement can significantly increase levels of HDL (“good”) cholesterol after eight weeks and lower total cholesterol levels after twelve weeks. Lower Cholesterol Levelsįollowing a meal replacement diet could also help lower triglyceride levels. ![]() However, as liquid diets don’t help you to change your long-term eating habits, it’s unlikely the changes in blood sugar balance remain after going back to solid foods. Another study found that 12 weeks of a diabetes-specific meal replacement supplement significantly improved Hb1Ac – a marker of long-term blood sugar balance – compared to traditional diabetes therapy (i.e., medication and counseling). Studies have found that six weeks of meal replacements can balance blood sugar and improve insulin resistance significantly more effectively than via a traditional low-calorie diet. Liquid diets automatically remove choice from the equation, so people tend to consume less sugar via meal replacements than when they choose their meals and snacks – even if they’re following a low-calorie diet. Meal replacement therapy can improve blood sugar balance more effectively than standard dietary advice in those with type 2 diabetes. A further study found that only one meal replacement per day leads to the same amount of weight loss as two meal replacements per day. In this study, the participants sustained weight loss for a further eight weeks after going back to solid food.īut you may not have to eat a full liquid diet to see weight loss benefits.Ī study in obese women found that partial meal replacement (replacing two meals per day) led to an average of 1 kg extra weight loss after two months compared to a low-calorie diet. Studies show that a high-protein meal replacement liquid diet can lead to 10 kg weight loss after 16 weeks. Liquid meal replacements usually contain all the nutrients you need and leave out the unhealthy stuff – sugar, saturated fat, unnecessary calories – so it’s no surprise that people lose more weight following a liquid diet compared to a standard low-calorie diet. The main benefit of electively choosing a liquid diet is weight loss. They are usually prescribed for patients before certain medical procedures, such as a colonoscopy, to clear the view of the inside of the colon. Clear Liquid DietĬlear liquid diets consist of water, broth, and some juices (without pulp). So, you’ll usually follow a liquid diet consisting of pureed foods for two to three weeks after something like gastric bypass surgery, gallbladder removal, and colorectal surgery. For instance, liquid diets before bowel surgery can minimize the spillage of bacteria during the procedure.Īfter any abdominal surgery, the bowels naturally stop moving for a time and a liquid diet prevents a functional obstruction ( ileus ) that can occur before normal peristalsis resumes. Sometimes, liquid diets are prescribed for a medical reason, such as before or after some types of surgery. In fact, the loss of toxins usually results from not ingesting them in the first place as part of the diet. Moreover, there’s very little clinical evidence that detox diets work for toxin elimination. Juice diets provide very few calories and can work for short-term weight loss, but usually lead to weight gain once resuming normal eating. Some people follow a short-term liquid diet – such as a juice cleanse or detox tea regime – for weight loss and detoxification. Your doctor may also prescribe meal replacement therapy for weight loss. There are many commercially-available meal replacement shakes and weight loss programs. Usually, you’ll replace one meal per day with all meals with shakes. You usually buy them as powders and add milk or water to make a shake. Liquid meal replacement diets provide all your daily nutrient needs in the form of a shake. There are different types of liquid diets for weight loss. Liquid diets can either be a full liquid diet or a partial liquid diet. Some people may be prescribed a meal replacement liquid diet for medical reasons if they can’t easily digest solid food, such as those with severe Crohn’s disease, after surgery, or due to intestinal obstruction. Others may follow a liquid “detox” diet such as a juice cleanse for other health reasons. Most people follow a liquid diet weight loss program as a personal choice to lose weight. This can be smoothies, shakes, juices, or meal replacements. A liquid diet is when you replace solid foods with liquidized foods.
