The 500-calorie diet plan has been devised to help lose weight. Doctors usually recommend this very low-calorie diet (VLCD) for individuals with obesity (BMI – over 30), whose health is at risk owing to the excess fat.

However, lactating and pregnant women are a big no for taking up this diet. This article explains what this diet is all about, its benefits, and its potential risks. Read on!

What Is The 500 Calorie Diet Plan?

The 500 calorie diet is an extreme form of a very low-calorie diet, i.e., it is extremely low in calories. It replaces the normal food routine with liquid supplements, meal replacement shakes, and bars for a specific period (1).

Having dietary supplements or meal replacements has become widespread in the US. According to the National Health and Nutrition Examination Survey, 2017– March 2020, over one-third of adolescents and nearly three out of five adults consume dietary supplements.

This restricted calorie consumption may help your body use the stored fuel source, i.e., fat. This, in turn, helps you shed pounds.

This is a type of 5:2 intermittent fasting plan that involves severe energy restriction for two non-consecutive days of a week and consuming 2000 calories on the other five days. This type of modified diet can fulfill 20-25% of energy needs on fasting days (2).

Studies showed that hypocalorici  XA very low-calorie diet with extremely low daily food energy consumption. Also known as semistarvation. intermittent fasting could help overweight and obese individuals lose weight. However, these studies are inconclusive, and more research is needed to confirm these findings (3).

What are the benefits of the 500-calorie diet? Find out in the next section.


The main benefit of the 500-calorie meals is that they may aid in rapid weight loss. Following a VLCD may help revamp your metabolism. It accelerates fat oxidation, helping you shed weight (4). It is great for those who need to lose weight to prevent any health risks.

But what if you are on this diet even if you don’t need to? Or what if you are on a 500-calorie diet for three weeks or more without being supervised by a doctor? Here’s what may happen.

Health Risks

1. Nutritional Deficiencies

Following a 500-calorie diet plan for long leads to nutritional deficiencies. A study published in the Nutrition Journal showed that a very low-calorie diet formula could lead to micronutrient deficiencies (5).

There was a significant reduction in the serum concentration of vitamin D, vitamin C, and zinc among obese people on a low-calorie diet for over 12 weeks (5).

Low-calorie diets can cause nausea, fatigue, diarrhea, intolerance to colds, menstrual irregularities, and hair loss. Lack of fiber in the diet can also cause constipation. This decreases the efficiency of the immune system and makes your body vulnerable to various ailments.

Jesse Feder, Registered Dietitian, says, “ A person can only survive short term on 500 calories a day. This is extremely low and can lead to serious health issues over time.”

2. Muscle Loss

Do you want to lose weight? Then, lose fat, not muscle. If you are on a VLCD for a prolonged period, you will start losing muscle mass instead of fat mass and might end up not liking your body transformation.

A very low-calorie, low-carbohydrate, low-protein diet can cause skeletal muscle loss (6). This can give you a “slim-fat” look and make your skin loose and droopy.

3. Metabolic Changes

Following a very low-calorie diet for a long period slows down metabolism. This ultimately leads to weight gain when you return to the original eating pattern.

A study published in Nutrition & Metabolism showed that a sudden reduction in body weight due to a low-calorie diet plan reduced the resting metabolic rate (RMR), but it was not as expected (7).

4. Decrease In Bone Mass

Weight loss due to following a calorie-restricted diet for a long time decreases bone mineral density and weakens bone strength (8).

A study showed that low-calorie diet-induced weight loss is accompanied by a loss of bone mass (9). Another study on 48 adults showed that calorie restriction (CR) reduced bone mineral density and bone mass (10).

5. Development Of Gallstones

Following a very low-calorie diet (500 calories) can increase the risk of developing gallstones.

A study published in the International Journal of Obesity showed that following VLCD for over one year resulted in cholelithiasis (the formation of stones in the gallbladder). Many of the adults had to undergo cholecystectomy (removal of the gallbladder) (11).

6. Deficiency Of Healthy Fat

A low-calorie diet is devoid of healthy fats to restrict unnecessary calorie intake. Consuming healthy fats in portion control provides satiety and helps you stay healthy (12).

Following a very low-calorie diet with restricted healthy fat intake reduces the absorption of fat-soluble vitamins, leading to deficiency (13).

You may be wondering who can follow this diet and who should avoid it. Find the answers below.

According to Jesse Feder, Registered Dietitian, “The amount of time a person can live on 500 calories a day depends on several factors, such as height, current weight, metabolism, and current health conditions. Overall, however, one can not live long on 500 calories a day. A popular 500-calorie diet plan is a version of intermittent fasting. It is called the 5:2 plan and means you eat a normal healthy diet 5 days a week and then only 500 calories on two non-consecutive days of the week.”

Who Should Avoid A Very Low-Calorie Diet?

Generally, doctors do not allow people with medical conditions to follow a VLCD. It is advisable not to follow any calorie-restricted diet under the following clinical conditions:
