Here is the simplest diet ever! These are three guidelines to lean eating - and if applied, you'll find that eating for a healthy, lean body just falls into place. This comes from Dr. Johnny Bowden, author of The 150 Healthiest Foods on Earth: Embrace fat! No, that's not a joke. If you're eating the right amount of total calories to maintain or lose weight, you won't store those fat calories - you'll burn them. Research shows that diets containing 50% fat are just as effective for weight loss as low-fat diets. Why? Because fat is filling - it makes food taste better - and those two things help you feel satisfied so you eat less. However, I'm not talking about the fat in Twinkies, I'm talking about the fat in meat, dairy, nuts, avocado, and olive oil. Worry more about the total calories you're consuming - not the fat grams. If you're eating whole foods, the fat will be good fat. Prepare your own meals. Think of it this way. As your number of home cooked meals increases, your fast food visits decrease. USDA scientists recently found that people eat up to 500 more calories on days they eat fast food than on days that they don't. Not sure where to start? Try CookingLight.com. You'll find that when you cook for yourself, you'll enjoy the food more, eat more nutritious meals, and you'll be burning calories by cooking and cleaning, instead of just sitting in your car ordering. *Eliminate added sugars. Dr. Bowden says that's the simplest way to clean up any diet. According to a USDA survey, the average person eats about 20 teaspoons of added sugar daily, or 317 empty calories. You could eat four navel oranges for that amount of calories if you really wanted something sweet! Those empty calories typically come from soda, baked goods, breakfast cereal, candy and fruit drinks. So get your sweet tooth fix another, more natural way - from real fruit. Real fruit has fiber, vitamins and antioxidants and nobody ever got fat from eating too many grapes.
