Some popular beliefs attached to weight loss have been shown to either have less effect on weight loss as commonly believed or are actively unhealthy. According to Harvard Health, the idea of metabolism being the "key to weight" is "part truth and part myth" as while metabolism does affect weight loss, external forces such as diet and exercise have an equal effect. They also commented that the idea of changing one's rate of metabolism is under debate. Diet plans in fitness magazines are also often believed to be effective, but may actually be harmful by limiting the daily intake of important calories and nutrients which can be detrimental depending on the person and are even capable of driving individuals away from weight loss.
Low-calorie diets usually produce an energy deficit of 500–1,000 calories per day, which can result in a 0.5 to 1 kilogram (1.1 to 2.2 pounds) weight loss per week. One of the most commonly used low-calorie diets is Weight Watchers. The National Institutes of Health reviewed 34 randomized controlled trials to determine the effectiveness of low-calorie diets. They found that these diets lowered total body mass by 8% in the short term, over 3–12 months. Women doing low-calorie diets should have at least 1,000 calories per day and men should have approximately 1,200 calories per day. These caloric intake values vary depending on additional factors, such as age and weight.
In terms of weight loss, you may be interested in trying the ketogenic diet because you’ve heard that it can make a big impact right away. And that’s true. “Ketogenic diets will cause you to lose weight within the first week,” says Mattinson. She explains that your body will first use up all of its glycogen stores (the storage form of carbohydrate). With depleted glycogen, you’ll drop water weight. While it can be motivating to see the number on the scale go down (often dramatically), do keep in mind that most of this is water loss initially.
You’ll also notice that men seem to lose more weight than women. This is actually based on body composition. Sorry ladies, but men just naturally have a leg up on losing weight! Why? Because most men have more muscle tissue, so they are simply able to burn more calories than women. Muscle tissue burns more calories than fat, even when the body is at rest. If you’re a woman, you can gain the benefits of additional muscle that will help you burn more calories by focusing on strength training. That will help the body weight you do have burn more calories, essentially boosting your metabolism.
There's not a lot of reliable information available about how the military diet plan was started — or, for that matter, who started it. MilitaryDiet.co and TheMilitaryDiet.com, the two main resource sites for the diet regimen, are both run by fans and proponents of the diet without any cited health professional credentials. According to them, though, the military diet plan is an intermittent fasting diet that combines three days of a strict, low-calorie meal plan with four days of eating whatever you want (as long as it still falls below the calorie intake).
Want to lose that belly fat? In your dreams! Seriously, though: a good night’s sleep is one of the best ways to get rid of that extra fat around your waist for good. Among the 60,000 women participating in the Nurses’ Health Study, those who snoozed for fewer than five hours a night were at the greatest risk of becoming obese and gaining 30 or more pounds over the course of the 16-year study period when compared to those who slept for seven or more hours.
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
Who actually created this diet? I can’t find any data on its development, much less any studies on its effectiveness or healthfulness. All of this supports my initial gut instinct that this diet has zero backing in science and health. Also, this diet appears to masquerade under several different names, the Cardiac Diet being one. Search both Cardiac and Military diets, and you’ll find the exact same three-day menu and protocol, although the Cardiac Diet is suggested to be a diet that physicians prescribe to obese patients for quick weight loss.
I used to be 100 pounds heavier than I am now. My eating habits were out of control and pretty much the epitome of mindless. I am A.D.D., I have two kids under four, and I work full time, so eating without constant distractions just doesn't happen. But over the years I’ve learned what it takes for me to lose my weight... and most importantly, keep it off.
