Natural Diets for Weight Loss - 3 Diets for Weight Loss?

Natural diets for weight loss are important for those who want to reduce weight safely. The U.S. Department of Agriculture's (USDA) Food Guide Pyramid gives you roughly 30 percent of your calories from fat, 15 percent from protein, and 55 percent from carbohydrate. Some other diets recommend different amount of macronutrients. But such diets are not optimal for fitness. Here's why:



Natural Diets for Weight Loss

1. Super lowfat diets. Cardiologist Dean Ornish, M.D., says a 10 percent fat diet protects his patients from artery damage and helps heal already-clogged arteries. However, Dr. Ornish and others who promote very lowfat diets require you to accept a total package, which includes regular exercise, stress reduction, meditation, and yoga. The combination of all those factors, not just the very lowfat diet by itself, probably unclogs blocked arteries. Also, for some individuals, a lowfat, high-carbohydrate diet tends to increase levels of circulating fats called triglycerides, while lowering healthy (HDL) cholesterol.

2. The zone or "40-30-30" diet. Promoters claim that following a 40 percent carbohydrate, 30 percent fat, and 30 percent protein diet speeds fat burning by better regulating and lowering the levels of insulin, the hormone that helps process carbohydrates. The science behind this reasoning is still unproven. Many of those who report success do in fact lose body fat, but mainly from calorie counting and cutting back on total calorie intake.



3. High protein diets. Several popular diet books advocate cutting back or eliminating carbohydrates. This means eating no bread, pasta, potatoes, fruits, and vegetables, as well as very few dairy products. Instead, you eat more protein from tuna, meats, and eggs. Following this carbohydrate-free eating plan will result in weight loss. As your body reacts to a very low-carbohydrate diet, it begins a metabolic state called ketosis. Rather than burning the standard mix of carbohydrate and fats for energy, your body now burns fats and fatlike compounds called ketones for fuel. To fuel your brain, however body, your body breaks down protein, not fat. It cannibalizes muscle, breaking into amino acid building blocks and then converting these to sugar. Less muscle equals slower metabolism, which is why people tend to gain weight as soon as they stray from the diet. This type of diet is nutritionally unbalanced. You miss out on key vitamins and minerals, such as calcium, folic acid, and vitamin C, along with fiber.

In conclusion, natural diets for weight loss plays important part for people who wants to stay healthy.
