High Protein, Low Carbohydrate Diets
This information came from the WebMD site - a trustworthy site, and I wanted to make sure it was credible. I've been reading for years about the success stories of those who lose weight on high protein diets - and I have no doubt that they're true. But I have also heard that there are many problems with high protein diets (so I'll warn you that I already had a slanted point of view) . I still think the most important thing about dieting is to eat the things you can continue eating for a life time.
"High-protein, low-carbohydrate diets have been widely promoted in recent years as an effective approach to losing weight. These diets generally recommend dieters receive 30% to 50% of their total calories from protein. By comparison, the American Heart Association, the National Cholesterol Education Program, and the American Cancer Society all recommend a diet in which a smaller percentage of calories are derived from protein (nutrients essential to the building, maintenance, and repair of tissues in the body).
..... Most experts are concerned that high-protein, low carb diets can cause a host of problems, particularly for the large segment of the population that is at risk for heart disease. What's more, the plan doesn't permit a high intake of fruits and vegetables, recommended by most nutrition experts because of the numerous documented health benefits from these foods.
The experts say to achieve permanent weight loss you must change your lifestyle. This means following a lower calorie diet that includes grains, legumes, fruits and vegetables combined with participating in regular physical activity."
High protein diets can cause a number of health problems, including:
* Kidney failure. Consuming too much protein puts a strain on the kidneys, which can make a person susceptible to kidney disease.
* High cholesterol. It is well known that high protein diets (consisting of red meat, whole dairy products, and other high fat foods) are linked to high cholesterol. Studies have linked high cholesterol levels to an increased risk of developing heart disease, stroke and cancer.
* Osteoporosis and kidney stones. High protein diets have also been shown to cause people to excrete more calcium than normal through their urine. Over a prolonged period of time, this can increase a person's risk of osteoporosis and kidney stones.
* Cancer. One of the reasons high protein diets increase the risks of certain health problems is because of the avoidance of carbohydrate-containing foods and the vitamins, minerals, fiber and anti-oxidants they contain. It is therefore important to obtain your protein from a diet rich in whole grains, fruits and vegetables. Not only are your needs for protein being met, but you are also helping to reduce your risk of developing cancer.
* Unhealthy metabolic state (ketosis). Low carb diets can cause your body to go into a dangerous metabolic state called ketosis since your body burns fat instead of glucose for energy. During ketosis, the body forms substances known as ketones, which can cause organs to fail and result in gout, kidney stones, or kidney failure. Ketones can also dull a person's appetite, cause nausea and bad breath. Ketosis can be prevented by eating at least 100 grams of carbohydrates a day. http://women.webmd.com/guide/high-protein-low-carbohydrate-diets
