High-Fat, Low-Carbohydrate Diets - Millions of Americans have joined the low-carb craze and started high-fat, low-carb diets such as the Atkins Diet, and the Zone Diet. They are made up of about 60% fat, 10% carbohydrate, and 30% protein. These diets say you can eat high amounts of fat and protein while getting very low amounts of carbohydrates in the form of vegetables. The main premise of the low-carb diet is that a diet low in carbohydrates leads to a reduction in bodyÕs production of insulin. The end result is that fat and protein stores will be used for energy. So you stuff yourself full of unlimited amounts of meat, cheese, and butter, and only eat a small portion of carbohydrates.
People who start the diet usually lose a great amount of weight, but itÕs not permanent weight loss. Instead of burning fat, the lose water and precious muscle tissue. Furthermore, these diets are low in several nutrients and contain excess amounts of cholesterol and saturated fats, substances that increase the risk of heart disease. Plus, regardless of what they claim, the enormous amounts of protein put a strain on your kidneys.
Low and Very Low-Fat Diets - Finally, you have your low-fat and very low-fat diets. Diets in this category include the Dr. Dean OrnishÕs Diet and the Pritkin Plan, among others. They are made up of about 13% fat, 70% carbohydrates, and 16% protein. These diets are mostly vegetarian diets and donÕt recommend eating a lot of meat. Like the low-carb diets, you can eat unlimited amounts of certain foods. Because you canÕt eat a lot of meat, these diets are deficient in zinc, vitamin B12, and essential fatty acids. Also, it is so restrictive that people find a hard time staying on it for life and end up gaining their weight back.
