Have Protein at Every Meal and Snack. Adding a source of lean or low-fat protein to each meal and snack will help keep you feeling full longer so you're less likely to overeat. Try low-fat yogurt, small portion of nuts, peanut butter, eggs, beans, or lean meats. Experts also recommend eating small, frequent meals and snacks (every 3-4 hours), to keep your blood sugar levels steady and to avoid overindulging.
Honestly? We don't know. While TheMilitaryDiet.com offers plenty of information, including a section with frequently asked questions, blog, and alternative meal plans for vegetarians, there are no authors, experts, or webpage owners listed. And while the name implies a military connection, the page doesn't actually claim any ties to the armed forces. (MensHealth.com reached out to the website for more information and will update if and when we hear back.)
Diets to promote weight loss can be categorized as: low-fat, low-carbohydrate, low-calorie, very low calorie and more recently flexible dieting. A meta-analysis of six randomized controlled trials found no difference between low-calorie, low-carbohydrate, and low-fat diets, with a 2–4 kilogram weight loss over 12–18 months in all studies. At two years, all calorie-reduced diet types cause equal weight loss irrespective of the macronutrients emphasized. In general, the most effective diet is any which reduces calorie consumption.
A small Feb. 20, 2017, study looked at the impact of a six-week ketogenic diet on physical fitness and body composition in 42 healthy adults. The study, published in the journal Nutrition & Metabolism, found a mildly negative impact on physical performance in terms of endurance capacity, peak power and faster exhaustion. Overall, researchers concluded, “Our findings lead us to assume that a [ketogenic diet] does not impact physical fitness in a clinically relevant manner that would impair activities of daily living and aerobic training.” The “significant” weight loss of about 4.4 pounds, on average, did not affect muscle mass or function.
Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
Wondering what fits into a keto diet — and what doesn’t? “It’s so important to know what foods you’ll be eating before you start, and how to incorporate more fats into your diet,” says Kristen Mancinelli, RD, author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss, who is based in New York City. We asked her for some guidelines.
Directions: Rinse 1 cup of quinoa in cold water. In a medium saucepan, combine quinoa with 1 tablespoon curry powder and 1 teaspoon turmeric. Add 2 cups low-sodium chicken broth and bring to a boil.
