This term may sound familiar to some people. But, this is one way you can try if you want to lose weight. As we know, diet failure is usually caused because you still consume foods that can cause fat. You can reduce solid food by replacing it with liquid. Here, we will discuss all about the clear liquid diet and how it can help you lose weight 

Definition of Clear Liquid Diet 

Clear Liquid Diet is a type of diet that can help a person lose weight by changing heavy food into plain gelatin, broth, and water. The goal is that our digestive system can digest without leaving the pulp in our intestinal tract. A clear liquid diet is also usually done before someone gets surgery. A patient is now allowed to eat foods and replace them with water only. A clear liquid diet is also temporary because you will not get enough nutrients and calories. When you take a clear liquid diet, you are only allowed to consume several food and drinks such as sports drinks, strained tomatoes, coffee and tea without cream and milk, gelatin, carbonated drinks, honey, sugar, water, and fruit juices. 

Types of Liquid Diets 

Basically, the liquid diet is divided into several types. The purpose of the liquid diet is to replace your main food with liquid. When you take a liquid diet, it does not mean you have to only drink mineral water. You can still consume some kinds of food that are converted into drinks. This is the best way to reduce the fat you consume because water does not contain fat. In addition, a liquid diet also provides a detoxification effect so that the body can get rid of toxins. 

  • Food Substitute 

A liquid diet can be the best way to lose weight and it can replace your food. In this liquid diet, you can consume liquid foods like shakes that can replace solid foods. In addition, you can also find several shake products that you are ready to consume for the liquid diet program. The purpose of this type of liquid diet is so that you still feel full and get essential nutrients for the body without having to make the body fat because most shakes have low calories. You can consume shakes at night or just morning. As a food substitute, the liquid diet with shake type still provides nutritional needs such as protein, minerals, and vitamins. 

  • Body Detoxification 

The liquid diet also has a function to detoxify the body. We know that our body contains many poisons that can cause cancer and gain weight. For body detox, you can choose the type of liquid diet by consuming drinks and juice. This type of liquid diet is not the same as the shake diet because you might only use natural ingredients such as vegetables and fruits so that it might not contain all the nutrients your body needs. You can make a cup of juice from your favorite fruits. You might not get enough carbohydrates or protein, but you can get lots of vitamins. 

  • Clear Liquid Diet 

This is one type of liquid diet that only relies on clear liquid and is usually taken when someone wants to carry out medical procedures such as surgery and others. As the name implies, the clear liquid diet only allows you to consume several types of liquid or drinks such as clear water, tea, apple juice, sports drinks, and other special drinks. 

Liquid Diet According Experts 

Nutrition expert Emilia E. Achmadi MS. RD explains that this liquid diet was originally made for people who are seriously ill. The condition of the person cannot digest food in his stomach so that food is given in the liquid form. 

But lately, this liquid diet is misinterpreted by those who lose weight. “This is one trend that I think is wrong. Something that becomes a trend does not mean that everything is good,” Emilia said. 

The liquid diet itself on the MD website is interpreted as a way to lose weight by limiting food intake in solid form and changing it to liquid. This liquid diet method is different, there are only consuming fruit and vegetable juices or shakes to replace solid foods that are usually eaten. Fruit and vegetable juices or shakes can be consumed three to four times a day. 

Another method of liquid diet is to replace solid food in the morning and afternoon with drinks, can fruit and vegetable juices or shakes. Those who use this second method can still eat solid food at dinner, but the food consumed must be healthy. This method usually also allows the culprit to eat healthy between meals. 

Is this liquid diet effective in losing weight? Many dieters admit that their weight loss is easy to lose. This weight loss occurs because when undergoing liquid diet calories can be reduced quickly. If he usually gets 2,500 calories daily, with a liquid diet, it can be 1,500. So it’s fast (losing weight) because the deficit is really fast. 

Rapid weight loss due to calorie reduction, according to Emilia, is not true. According to him, these dieters become mistaken. When they lose weight, they feel that they are losing fat too. When in fact the loss is not fat but only fluid or muscle mass. 

A liquid diet is done in the short or long term is not recommended. That’s because basically the human body has been designed for the process of chewing. While liquid dieters do not need to chew because their food is in liquid form. 

Chewing activity is still important because at that time saliva is produced. At the time of producing saliva, the carbohydrate digestion process has occurred in the body. 

A diet expert who is also the author of the book “Skinny Chicks Don’t Eat Salads” says that a liquid diet only provides short-term benefits. The target of fast weight loss is achieved, but the side effects will be felt after the diet is stopped. As long as you only consume liquid food, your metabolism decreases. As a result, when you return to eating solid food, your weight will quickly return to normal. 

A similar opinion was also expressed by Anne Fletcher, the author of the book “Thin for Life” who is also a weight consultant. In addition to affecting metabolism, liquid diets also have a psychological effect thereby reducing the chances of success. 

Although it can meet nutritional needs, food in liquid form will not present the sensation of a full stomach so it tends to always be hungry. If the satisfaction that should be obtained when eating is taken, someone will be difficult to survive. 


A liquid diet is a diet program inspired by the bestseller book “Lose 21 Pounds in 21 Days”. Because it was introduced by Roni DeLuz, a naturopathic doctor from Martha’s Vineyard Inn, this diet is also often referred to as Martha’s Vineyard Diet Detox. 

This diet program is carried out for 21 days with a target weight loss of 21 pounds or about 9.5 kg. During the program, participants did not eat solid food at all but only juice and vegetable broth.
