Probably, and there are a few reasons why, Keatley says. For starters, people usually reduce their daily caloric intake to about 1,500 calories a day because healthy fats and lean proteins make you feel fuller sooner—and for a longer period of time. And then there’s the fact that it takes more energy to process and burn fat and protein than carbs, so you're burning slightly more calories than you did before. Over time, this can lead to weight loss.
While there are studies that show the health and medical benefits of weight loss, a study in 2005 of around 3000 Finns over an 18-year period showed that weight loss from dieting can result in increased mortality, while those who maintained their weight fared the best. Similar conclusion is drawn by other studies, and although other studies suggest that intentional weight loss has a small benefit for individuals classified as unhealthy, it is associated with slightly increased mortality for healthy individuals and the slightly overweight but not obese. This may reflect the loss of subcutaneous fat and beneficial mass from organs and muscle in addition to visceral fat when there is a sudden and dramatic weight loss.
The 3 Day Military Diet will deliver some impressive weight loss results if you stick with it as outlined during the 3 days on. Many users report military diet results between 3 and 10 pounds lost per cycle. For the best results, you will also need to make sure you don't go over the 1500 calorie limit during the other 4 days off. During those off-days, keep away from alcohol, sugary drinks, and other foods that would otherwise limit weight loss.
The Military 3-Day Diet plan is one of the most regimented diets that I’ve ever reviewed for Cooking Light. It’s free to sign up, and participants can download the plan directly from militarydiet.com. The plan is a weekly cycle that includes a three-day meal plan, followed by 4 days off. You can repeat this cycle as many times as you need until your weight loss goal is met.
The idea is that the fasting induces mild stress to the cells in your body, helping them become better at coping with such stress and possibly helping your body grow stronger. The verdict is still out regarding the diet’s long-term effectiveness with weight loss, according to a review of preliminary animal research published in January 2017 in Behavioral Sciences. (17)
"Protein is great for fat loss. It helps build and preserve lean muscle tissue and can increase the amount of calories you burn. It’s also a great source of energy that helps you feel fuller for longer, so you’re less tempted to snack. Good sources include chicken breast, tuna, eggs, milk and chickpeas. And if you’re finding it difficult to avoid snacks that are high in carbohydrates, try substituting them for protein shakes or bars. Remember also to opt for the lean sources of protein because some sources can be high in saturated fat."
The military diet is similar to other three-day diet plans (think: the Mayo Clinic and Cleveland Clinic three-day diet plans) as it claims to promote weight loss in a short period of time by restricting calories. The diet also bears a striking resemblance to the retro Drinking Man's Diet (or the Air Force Diet) of the '60s, according to Adrienne Rose Johnson Bitar, Ph.D., postdoctoral associate at Cornell University who specializes in the history and culture of American food, pop culture, and health. Much like the military diet, the Drinking Man's Diet incorporated martinis and steak in the diet but kept carbohydrate and calorie counts fairly low, she explains. "Both of these diets were low-calorie or low-carb plans that promised impressive short-term results, but included unhealthy or indulgent foods," says Bitar. (Another unhealthy diet trend that includes lots of red meat: The Vertical Diet. Safe to say, you can skip that diet plan, too.)
Around this time, Bernarr Macfadden, an American exponent of physical culture, popularised the use of fasting to restore health. His disciple, the osteopathic physician Dr. Hugh William Conklin of Battle Creek, Michigan, began to treat his epilepsy patients by recommending fasting. Conklin conjectured that epileptic seizures were caused when a toxin, secreted from the Peyer's patches in the intestines, was discharged into the bloodstream. He recommended a fast lasting 18 to 25 days to allow this toxin to dissipate. Conklin probably treated hundreds of epilepsy patients with his "water diet" and boasted of a 90% cure rate in children, falling to 50% in adults. Later analysis of Conklin's case records showed 20% of his patients achieved freedom from seizures and 50% had some improvement.
We reached out to two experts to see what they thought — and if the diet works. "It’s a low calorie diet that includes typical American foods," said Janis Jibrin, MS, RD, an adjunct professor of Nutrition at American University. "It’s nutritionally deficient, but not as crazy as some (i.e. juice fasts)." When it comes to the meal plan, she's not a fan. "It’s too low in many nutrients," she explains. Day 2 alone is "so low in fiber, iron, calcium and other nutrients, yet it manages to hit the daily sodium max. (Actually, most health authorities recommend 2,300 mg as a max, so this diet exceeds it.) Sure, the other four days offer more calories and nutrients, but even so, you’re still skimping."
