A patient once described to me his diet which included healthy meals, such as "good foods like steak." He experienced initial success with the Atkins Diet in rapidly losing fifteen pounds, and then, unfortunately gained back all of the weight within months.
The Atkins Diet was popular early in this decade as an easy way to rapidly drop weight. True, the diet will allow you to lose a large amount of weight at first, most of it in water. But, in the long-term, it isn't successful. How many people do you know who have lost weight, kept it off for several years, and attribute their success to the Atkins Diet? I don't know a single one.
Ingesting a diet high in saturated animal fat and protein is not good for the body. Diets high in saturated and animal fat have been shown time and time again to increase the risk of heart disease and cancer.
The European Prospective Investigation into Cancer and Nutrition, a multi-national study of thousands of people, demostrated that high-protein, low-carb diets increase mortality risk.
A low-fat, vegetarian diet, with lots of fruits, vegetables, and whole grains, with lean protein, really is the best option for health and permanent weight loss.
