How Much Weight Can You Lose on a Liquid Diet In 3 Days? Magic Detox or Insane?


How much weight can you lose on a liquid diet in 3 days? MAGIC DETOX OR INSANE? Today’s title speaks for itself.

We’ve all heard of liquid diets before. They sound great because they promise to help us lose weight quickly without counting calories or exercising.

But how much weight can we really lose on a liquid diet? And do these diets work?

In this article, I will answer these questions and tell you exactly how much you can expect to lose on a liquid diet. Then I’ll explain why most liquid diets fail and why the ones that succeed are insane.


How Much Weight Can You Lose on a Liquid Diet In 3 Days?

In the last couple of weeks, I’ve spent many hours reading and studying liquid diet reviews and articles to research this topic in great depth. First, it’s not something I recommend doing for longer than three days at a time. After that, four maintenance days must follow.

Based on that, I do not recommend this 3-day diet for people who are only slightly overweight. However, it is more effective for people who are overweight than 20 pounds: it can be an excellent initial solution to lose the initial 8-10 pounds and then proceed with other special dietary regimes.

Many articles out there don’t give you a clear answer to the question above, so I will cut right to the chase.

If you are at least 20 pounds overweight, you should be able to lose 7-10 pounds in 3 days following a fluid diet. This will be slightly less if you only need a couple of pounds/kg to lose. 

If you are, for example, 2-4 pounds overweight, you might reach your goal of losing that in the 3-day liquid diet.

I’ve tried a 3-day liquid diet this week and can confirm these numbers. I weighed 187.3 pounds (my normal weight) and lost only 2 pounds in 3 days.

There’s not more to it. These are the numbers I can give you. Let’s now dive a little deeper into the subject and see how a liquid diet works and if there are better options to lose weight healthily.

What are the Main Liquid Diet Plans?

1. Detox Liquid Diet (Cleaning Liquid Diet)

Detox diets have become increasingly popular over the last decade. These diets involve consuming certain types of liquids, such as fruit juice or herbal tea, for a short period. People often use these diets to cleanse their bodies of toxins, improve digestion, boost energy levels, lose weight, or reset their systems.

A detox diet helps our bodies eliminate harmful substances like drugs and alcohol, heavy metals, pesticides, preservatives, artificial colors, chemicals, etc. This process is called detoxification. Some people even believe that detoxifying diets could potentially cure health problems.

There are many different kinds of detox diets out there. For example, one might consume only green juices while another may only eat raw foods. And still, others may follow a specific protocol.

2. Meal Replacement Liquid Diet

Liquid meal replacements are popular among dieters because they allow people to eat less food while still feeling satisfied. Liquid meals come in many forms, including shakes, drinks, bars, soups, and even pills.

As I mentioned, one liquid meal replacement product is the shake, which contains carbohydrates and proteins.

Shakes are typically consumed in place of a regular meal. A typical shake contains around 300-400 calories, depending on how much protein and carbohydrates it contains.

Some liquid meal replacements are high in protein and low in fat. Protein helps build muscle mass and maintain lean body mass. Fat slows down digestion and keeps blood sugar levels stable.

High-fat liquids tend to make people feel fuller longer. In addition, some studies suggest that liquid meal replacements might be as satisfying as solid meal replacements.

3. Medical Liquid Diet

Doctors prescribe a liquid diet to prepare patients for surgery in the near term or help them recover from injuries. This diet is not designed for weight loss. It requires special attention and supervision from a doctor. It may also help ease digestive problems.

A medically prescribed liquid diet requires the patient to consume liquids only. They can only drink water, broth, juices, popsicles, syrups, and tea.

In short, if you are comfortable, you can follow a liquid medical diet for a couple of days or so. However, following a meal replacement diet is best if you want to lose weight.

Solid foods and liquids will help ensure you get the full nutritional benefit. You might not need to go through the medically prescribed water or juice diet if you’re trying to lose weight.

Scientific Proven Benefits Of A Liquid Diet For Weight Loss

The liquid diet is one of the most popular today because it is easy to follow and does not require much preparation. It is also beneficial for people looking for ways to lose weight fast without cutting down on calories. However, there are some drawbacks to this type of diet.

For instance, you cannot eat solid foods like bread, pasta, rice, and potatoes while following a liquid diet. This makes it difficult for people who want to consume certain nutrients such as carbohydrates and proteins. In addition, the lack of food causes the body to go into starvation mode, which triggers hunger pangs.

However, a couple of proven benefits are also associated with the liquid diet.

– Weight Loss

Most people go on a liquid diet because they want to lose weight. When you drastically reduce your caloric intake, you’ll create a calorie deficit in your body. As a result, you’ll burn more calories than you consume. This is the basis for weight loss and can be done easily.

– Elimination Of Toxins

When we eat solid food, our bodies work to eliminate toxins and put forth an effort to dissolve them. A liquid diet emphasizes cleansing the detoxifying organs of our bodies, which will result in a cleansing of the system after we’ve been eating solid foods for some time.

Drinking lots of water flushes out the kidneys and bladder, eliminates toxins from the colon and digestive tract, and aids digestion.

– Better Organ Function

During a liquid diet, vegetable and fruit juices are essential for providing the body with plenty of nutrients, vitamins, and minerals. This will help improve the function of all your organ systems, which is good for our overall health.


How Effective Is A Liquid Diet?

Weight loss happens when you burn more calories than you consume. If you eat less and exercise more, you will naturally drop pounds.

But what about liquid diets?

They eliminate excess calories and fat from the diet, leading to weight loss.

Many liquid diet plans start with only 400 to 800 calories per day. This is a drastic reduction compared to regular eating habits.

And since you’re eliminating foods like bread, pasta, rice, potatoes, and even some vegetables, it can lead to nutrient deficiencies. In addition, most liquid diet plans don’t include enough fiber to keep you full.

Replacing meals with high-protein drinks does help you shed extra pounds. However, there are many downsides to this type of diet, including hunger pangs, muscle cramps, low energy levels, and bloating.

It doesn’t suit everyone. It would be best if you were motivated and disciplined to succeed at sticking with it. With any diet, the more obese you are, the more pounds you can expect to lose

Will The Shredded Pounds Stay Off?

Liquid diets are trendy diets that we see pop up now and again. While they seem like a great idea, there are several reasons why they don’t seem to work long-term.

The idea behind liquid diets is straightforward: cut out solid foods entirely and replace them with liquids like water, juice, smoothies, and protein shakes. While there are plenty of benefits to liquid diets — including convenience, ease of use, and lower cost — experts say they don’t work well as a long-term solution for weight loss.

One downside of liquid diets is the slight chance that you’ll be unable to maintain the weight loss for long periods. If you’re trying to lose weight, cutting back on calories will force your body into starvation mode, which will cause you to burn fewer calories.

95% of people who lose weight by following a liquid diet can expect their weight to return. When this occurs, your body conserves as many calories as possible to have enough energy for survival. If you stop following the 3-day diet, you’ll gain all the weight you’ve lost.

You must eat liquid and solid foods to keep weight off for good. Studies show that the best results come from combining meal replacements with regular exercise and lifestyle modifications.

These results don’t just apply to liquid diets; they apply to any diet. You can lose weight in several ways, but if you don’t make a long-term commitment to changing your eating habits and lifestyle, you can expect to regain any lost weight.

What Is The Downside Of A 3-Day Liquid Diet?

A liquid diet isn’t necessarily great for everybody. It could be even downright dangerous when you exaggerate it. You might think restricting calorie intake to fewer than 500 per day is good for weight loss, but it’s very unhealthy.


Because without sufficient food, you won’t get enough nutrients. And those are necessary to keep your body functioning correctly.

If you’re going to start a liquid diet, talk with your doctor first. Choose a plan that allows you to eat one or two regular daily meals and helps you develop healthy lifestyle habits.

Ensuring that the shakes you prepare contain enough nutrients to meet your daily requirements is essential. Follow the instructions for your liquid diet plan, aiming to lose weight slowly over four weeks, for example.

If you want to start a 3-day liquid diet, you are likely destined to trigger a “yo-yo” effect which will have no long-term success.

If you do a 3-day liquid diet to lose weight, be smart. Realize that it’s not a long-term strategy for maintaining a healthy lifestyle; it’s a short-term approach to losing weight quickly.

See it as a jump start for your healthy diet journey. My approach would be to start with a 3-day liquid diet and then start a regular, healthy, maintainable diet.


FAQ’S Corner

How Much Weight Can I Lose in a Week on a Liquid Diet?

Although I advise against liquid dieting for longer than 3-4 days, you must be able to lose over 10 pounds in a week. I can’t give you an exact number because it also depends heavily on your metabolic rate and body type.

Can I Lose 30 Pounds in a 2-Week Liquid Diet? 

WHAT? Yes! Somebody asked me this exact question. Let’s roll with it.

The answer is no. You might be able to lose a lot of weight in the first week. Say 10-12 pounds, as I explained earlier. Remember that most weight loss is water weight and excess body fat. After the first week, the rapid weight loss process will slow down, and you’ll be able to lose maybe 4-6 more pounds.

I strongly advise against trying it out since this is unhealthy and dangerous.

How Much Protein Powder Should I Add to a Full-Liquid Diet?

Protein powders can be used by most people who follow a liquid diet to meet their protein requirements. A typical daily protein intake for someone following a complete liquid diet is 40-50 grams.

How Long Can Someone Safely Be on a Liquid-Only Diet?

How long someone should stay on a liquid diet depends on the person, but most people only need it for 1-5 days. A physician or dietitian must supervise the diet if you wish to continue longer-term.

Is Doing a Liquid Diet Healthy?

No. A long-term liquid diet should only be used if prescribed by a professional for a specific medical reason. This isn’t the best option if you’re looking for a diet plan because it doesn’t provide enough fiber, vitamins, and minerals.

That said, a liquid diet has a lot of health benefits if you don’t overdo it. Two- three days is the sweet spot here.

Can I Eat Ice Cream

You can eat ice cream, frozen yogurt, or ice pops made from ingredients that melt at room temperature if they don’t contain nuts, candy, and other hard pieces.



Liquid diets aren’t meant to replace solid foods entirely. Instead, they’re designed to help you kickstart your metabolism and shed pounds quickly. However, because these diets are usually deficient in calories, they won’t provide the nutrients you need to maintain a healthy lifestyle.

That said, if you want to lose weight fast without worrying about what you’re going to eat, a liquid diet might be right for you. But remember that it’s not a magic bullet; you must exercise regularly and watch what you eat.

So if you’re serious about shedding pounds, you shouldn’t rely solely on liquid diets. Create a healthy fitness and eating routine if you want to lose weight healthily and prevent future weight gain
