What Is The 4-Day Military Diet?

Everybody is up for the quick fix when it comes to dieting. That is why a lot of diet methods are promising to help people lose weight in just a span of days, like the 4-day military diet – another diet method that everyone is raving about. Let us find out if it could really give you the weight you want.


The military diet is characterized as an extremely low-calorie diet designed to help followers lose 10 pounds per week. The 3-day diet outlines specific foods to be consumed for breakfast, lunch, and dinner. Followers maintain a regular, healthy diet for the following 4 days each week (15).

The Military Diet plan features a step-by-step food and fluid guide that provides between roughly 860 to 1150 calories each day. It is all based on how many calories the body needs to gain one pound of fat – 3500 calories a day (19).

4-Day Military Diet: Is It Safe?

There are no studies that show the health benefits of the 4-day military diet. However, there are research and studies that show significant health benefits of a low-calorie diet.

One study published in Cell Metabolism Journal this month concluded that cutting calorie intake by 15% for over two years can reduce oxidative stress, which may slow aging and protect against diseases such as cancer, diabetes, and Alzheimer’s.

A different, more extreme calorie-restricted diet study published in Science Translational Medicine showed that so-called fasting-mimicking diets practiced for five days a month for three months can also help the body with aging. In this study, the fasting-like diet reduced body weight and fat, lowered blood pressure, and decreased the hormone IGF-1, which has been implicated in aging and disease.

Although low-calorie diets have health benefits, the 4 day military falls under the category of rapid weight loss diet. And just like any other rapid weight loss diet, it also has its health risks.

  • Gallstones

Those who lose weight rapidly, such as the promised 10 lbs per week in the military diet, are at risk of developing gallstones. When you starve for a long period or lose weight quickly, your liver releases extra cholesterol into the bile. Fast weight loss can also prevent the gallbladder from emptying properly. Weight-loss surgery may lead to fast weight loss and a higher risk of gallstones (5).

Your chances of developing gallstones may depend on the type of weight-loss treatment you choose. Diets or surgeries that cause fast weight loss may be more likely to lead to gallstone problems than diets or surgeries that lead to slower weight loss. If you have silent gallstones, you may also be more likely to develop gallstone symptoms.

  • Muscle Loss

One well-established risk of rapid weight loss is muscle atrophy. Studies comparing the effects of rapid weight loss with slow and sustained weight loss show that those experiencing rapid loss are more likely to have muscle wasting. Over time, loss of muscle mass has been associated with higher levels of morbidity and mortality. The negative consequences of muscle atrophy can be exacerbated in those with type 2 diabetes.

According to a study, glycogen is stored in the liver, muscles, and fat cells in a hydrated form (three to four parts water) associated with potassium. The total body potassium changes early in very low-calorie diets primarily reflect changes in glycogen storage. When you first start restricting calories, your body turns to its stored glycogen and burns it for energy. Although a very low-calorie diet may help you lose weight fast, a lot of the pounds you shed may come from glycogen and water.

  • Lack Of Nutrients

Due to the lack of variety in the foods allowed on the military diet, the diet may not provide adequate nutrition. To be healthy, you need a balance of foods from different food groups. It is difficult to get good nutrition and feel satisfied on a very low-calorie diet. Furthermore, consuming as few as 800 calories daily may not give you the energy you need for daily living and regular physical activity, especially if you eat the same foods every day (17).

  • Slower Metabolism

When you don’t eat enough, your body goes into survival mode and starts breaking down muscles to release the glucose stored inside, which can be used for energy. Because you’re not taking in enough calories, your body slows down your metabolism in an effort to conserve energy. You might feel sluggish and cold, and even have gastrointestinal abnormalities, such as constipation (2

Other Risks:

  • hair loss
  • skin thinning
  • hypothermia
  • cholelithiasis
  • electrolyte derangement

Military Diet Results: Is It Effective For Weight Loss?

The military diet is characterized as an extremely low-calorie diet designed to help followers lose 10 pounds per week. However, there have been no studies on the military diet yet. But the average person is very likely to lose a few pounds due to the week-long calorie restriction.

A weight loss of one to two pounds a week is the typical recommendation. Although that may seem like a slow pace for weight loss, it’s more likely to help you maintain your weight loss for the long term (11).

It is also essential to know the recommended daily calorie requirements for men and women. In order to know how many calories you are going to cut in your diet to lose weight.

Daily recommended calorie consumption for males:

Age 19-20

  • Sedentary: 2600
  • Moderately active: 2800
  • Active: 3000

Age 21-30

  • Sedentary: 2400
  • Moderately active: 2600-2800
  • Active: 3000

Age 31-50

  • Sedentary: 2200-2400
  • Moderately active: 2400-2600
  • Active: 2800-3000

Age 51+

  • Sedentary: 2000-2200
  • Moderately active: 2200-2400
  • Active: 2400-2800

Daily recommended calorie consumption for females:

Age 19 to 30 years

  • Sedentary: 1800-2000
  • Moderately active: 2000-2200
  • Active: 2400

Age 31-50 years

  • Sedentary: 1800
  • Moderately active: 2000
  • Active: 2200

Age 51+ years

  • Sedentary: 1600
  • Moderately active: 1800
  • Active: 2000-2200

If you want to lose weight, you would have to consume less than the amounts listed above. Remember that one pound (0.45 kilogram) of fat equals 3500 calories. So, to lose one pound a week, you need to reduce by 500 from what you normally eat each day (500 calories x 7 days = 3500 calories) (21).

The Bottom Line: Can A 4-Day Military Diet Help You Lose Weight?

Yes, the 4 day military diet can help you lose weight but not as much and not as quick as it promises. If you want to lose weight, you would have to consume less than your recommended calorie intake per day. The less you consume, the faster you lose. However, it is important to follow a healthy, well-balanced diet that provides enough energy and essential nutrients, and to engage in physical activity.

Before trying the military diet, you should first ask the supervision of a trained expert, either your dietitian or nutritionist.
