The military diet requires people to follow a low calorie diet for 3 days and then return to regular eating for 4 days. Across the first 3 days, daily calorie intake is restricted to 1,400, 1,200, and 1,100 calories. The diet is high in protein and low in fat, carbohydrates, and calories.

On the Military diet, you’re meant to follow a structured diet that provides 1,100 to 1,400 calories — men can have 100 more calories than women — per day for three days of the week. The foods you can eat include proteins, fat, dairy, eggs, grains, fruit, vegetables, vanilla ice cream, water and coffee.

The Military Diet consists of a three-day eating plan of three meals a day with no snacks, followed by four days of slightly less restricted eating for three meals and two snacks.

For three days, you follow the strict portion of the diet, where you eat a minimal number of foods in specific amounts, adding up to about 1,000 calories per day. Once the three days are over, you can switch to a slightly more varied diet, as long as you keep it low-cal, around 1500 calories. Repeat this cycle until you reach your desired weight.
