A liquid diet involves consuming clear liquids. Bone broth, water, or juices without pulp are the foods that doctors allow. Going on an unsupervised liquid diet for weight loss is not recommended. However, if your doctor permits, you can use this diet for no more than one day to flush out toxins and kickstart your metabolism. Do not follow it for more than a day as it can be unsafe.

What Is A Liquid Diet?

Liquid diets (also called clear liquid diets) are low-calorie foods that are liquid at room temperature (1). You can either replace one or two meals of your day with liquid foods or go on a total liquid diet. In a liquid diet, you will be consuming calories in liquid form. Fun Fact Liquid-based diets have a long history. It is said that William the Conqueror, the first Norman king of England, went on a liquid diet around 1087 AD to lose weight.

You can juice fruits and veggies, make smoothies, or have soup. This diet is most often used for weight loss, but how good is it?

How Do Liquid Diets Help In Weight Loss?

Liquid diets are the go-to diets for many dieters. This is because they help save time, improve metabolic rate, detoxify the body, and support the digestive system, resulting in weight loss and better overall health. Listed below are the ways liquid diets could aid weight loss.

1. Low In Calories

Liquid diets are low in calories as they consist of watery-clear fluids. Studies in The American Journal of Clinical Nutrition showed that very-low-calorie diets, including a liquid diet consisting of no more than 500 calories a day, could be effective in reducing weight. This type of diet could work better compared to a low-calorie diet or a restricted normal food diet (2). When you consume fewer calories, your body will start using up the stored glycogen or fat as the source of fuel. This, in turn, could lead to weight loss. A study published in The International Journal of Obesity showed that a low-calorie diet or very low-calorie diet resulted in muscle glycogen depletion for a short period. Body fat also decreased, resulting in weight loss (3).

2. Detoxify Your Body

Liquid diets are an excellent way to detoxify your body.

The juices/broths/smoothies are rich in vitamins, minerals, and dietary fiber. Rat studies have shown that fruit or vegetable juices are rich in antioxidants and can prevent oxidative damage (4). The dietary fiber helps cleanse the digestive tract and improves gastrointestinal health (5). Both these actions could have a beneficial impact on weight loss.

3. Nutritious

Liquid food in the juice or smoothie form offers rich nutrition. Remember to drink the juice/smoothie immediately if you are using a centrifugal blender. Replacing your dinner meal with low-calorie liquid foods improves body composition parameters and may also aid weight loss. In a study, the group of subjects who took a liquid meal replacement seemed to have better weight parameters (6). Maintaining a balanced calorie intake along with a liquid diet throughout the day can help provide the required nutrients to the body.

4. Easy On The Digestive System

Juices/smoothies/broths are easy on your digestive system. They aid proper digestion, absorption, and excretion. Moreover, the little dietary fiber and water in the liquid diet (by including pulp in juices or smoothies) can keep you full for a long duration. As per one study, a liquid meal replacement was found to have more fiber than a solid meal replacement (7).

5. Convenient

You don’t have to wait for the pan to heat up or scroll through recipes online. You may simply toss all the ingredients into a blender, and your breakfast/lunch/dinner is ready. This is a major advantage, more so if we tend to skip a meal or order unhealthy food as cooking could be a time-consuming process. Starving or eating unhealthy could only lead to weight gain in the long run. These are the many advantages of a liquid diet. The diet is available in different types, and in the following section, we will explore those.

Types Of Liquid Diets For Weight Loss

For beginners, following a liquid diet can be tough. Also, if you are not comfortable going on a complete liquid diet, you have an alternative. Here, we have discussed the different types of liquid diets. Remember to talk to your doctor/dietitian before trying any of these.

1. Detox/Cleansing Liquid Diet

Detox or cleansing liquid diets have gained popularity in the recent past. They may help to detoxify your body, and you may see some results when you go on a detox liquid diet once a week for a month. In this diet, you will only drink vegetable/fruit juices with herbs for a day. It will not only be a new experience but also can feel refreshing. A few examples of detox/cleansing liquid diets are water fasting and the Master Cleanse. However, research on detox diets is very limited. We suggest you speak to your doctor about the safety of such diets (8).

2. Meal Replacement Liquid Diet

Meal replacement liquid foods or shakes are low in calories and could be effective in weight loss. Certain liquid meal replacement products are high in protein and fiber and low in fat. These could be more effective in regulating appetite and curbing hunger pangs. Some research suggests that liquid meal replacement diets could be as satiating as solid meal replacement diets (7). The shakes or juices that you take in the place of a full breakfast or lunch are usually low in calories. They can also contain all the macronutrients (protein, carbs, and fat) and most micronutrients (vitamins and minerals) These products are specifically designed to replace solid foods (which may have a higher total calorie count per serving).

3. Medical Liquid Diet

This diet is not for weight loss. You need special attention and supervision by a doctor. This liquid diet is prescribed by a doctor to prep a patient for surgery in the near future or help them recover from an injury. This diet could also be prescribed to ease digestion issues. Medically prescribed liquid diets require the patients to be on a clear liquid diet. They can only drink water, broth, apple juice, popsicle, syrup, and teas. Takeaway Point: If you are comfortable, you can go on a detox diet for a day. But for weight loss, it is recommended to go on a meal replacement diet. This will ensure that you get the benefits of solid food as well as liquid juices/broths. If weight loss is your goal, you may want to skip the medically prescribed liquid diet. StyleCraze Trivia Beyoncé revealed that she lost 20 lbs for her role in ‘Dream Girls’ in 2006 by following a strict liquid diet known as the Master Cleanse.

Infographic: Flavored Water Recipes For Liquid Diet A liquid diet helps one lose weight, revs up metabolism, and flushes out toxins effectively. However, one may feel it monotonous to drink only water to curb the thirst. Hence, flavored water can be a good choice. The following infographic lists a few recipes for flavored water. Check them out! A liquid diet involves replacing all or some meals in a day with clear fluids like broths, juices, and soups. A liquid diet for weight loss can work by drastically cutting down the number of calories consumed in a day and detoxifying the digestive system.

Avoid this diet if you are pregnant, lactating, underage, or above 60 years of age (unless prescribed by your doctor).
