Types of diets.
Today there exist diets to all tastes and wallet – low-carb, high-fat etc. etc. Thousands and thousands of American people have tried Atkins or Zone diets which imply that you take 60% fat, 30% protein and 10% carbohydrate. The percentage of carbohydrate in such diets is the lowest so you can eat only 10% of vegetables a day. This is because low-carb diets lead to the reduction of insulin. The fat and protein you take or have already stored in your body will be used for energy that you need to survive. So these diets imply that you can eat meat, cheese, butter unlimited but be careful about carbohydrates.
But if you look at such diets closer you will see the other side of the coin. Yes, you will definitely lose great amounts of weight but it is not a permanent loss. You do not burn the fat that you do not need, you lose the muscle tissue and water that you need. Besides, these diets eliminate some of the essential products and make your diet high in fats that is why your level of cholesterol increases and so does the risk of heart diseases. These diets also suggest that you take in a lot of protein which might cause problems to your kidneys.
Then come moderate fat diets like weight watchers, Jenny Craig and the USDA Food Guide pyramid. Such diets imply that you take in 60% carbohydrates, 25% fat and 15% protein. These diets also make the dieters eat such products as fruit, whole grains, vegetables and products rich in fatty acids like salmon and olive oil. The dieters should keep the amount of nutrients that they take in from all the categories. Let’s take weight watchers as an example. This diet is based on a specific amount of points that you get for what you eat. These points are counted according to the number of calories, fiber and fat. So, the dieter might chose to eat more carbohydrates and this could lead to serious problems like the deficiency of zinc, iron and calcium. Though such diets if followed correctly are the best among the existing ones.
The last group of diets includes low and very low fat diets like the Dr. Dean Ornish’s Diet and the Pritkin Plan. These diets imly that you should eat 70% carbohydrates, 16% protein and 13% fat. As you can see they are almost vegetarian diets where you cannot eat a lot of meat. So, as you understand there aill be a deficiency of B12 vitamin, zinc and fatty acids.
