The low calorie, low-carbohydrate, high-protein diets do help people lose weight, mostly because a person consumes fewer calories. There are some initial changes that cause a loss of pounds, such as emptying the colon and eliminating water from the body, but these temporary changes are not loss of body fat.
When carbohydrates are eliminated or drastically reduced, a person’s appetite is diminished. That is because the body switches over to using protein and fat, and there is a chemical change in the body, called ketosis.
The hardest part of dieting for many people is controlling their appetites. But if you can consume just the same number of calories, regardless of the diet composition, you will lose the same amount of weight.
All low calorie diets are potentially dangerous. Semi-starvation is not the right approach to weight loss. Yes, the very low carbohydrate diets can lead to fatty deposits in the liver. The emphasis on proteins, particularly fat meats and other foods high in saturated fats, and even eggs, may significantly increase the total cholesterol levels.
The proper diet for weight loss is not a low calorie diet, but rather a balanced diet that includes all of the four basic food groups. It should provide 1,200 calories a day for adults. Anything less can lead to problems and needs to be managed by a physician. The low calorie diets being promoted today usually produce only temporary results. All you need to do is look at Oprah Winfrey’s story of rapid weight loss and not too long afterward, a rapid weight gain, back to where she started. That is the usual story. If you want to lose weight, you need to be on a program you can follow for life.
Don’t forget the value of exercise. A proper limited-calorie diet (rather than a very low calorie diet) along with a good exercise program is essential. And it really doesn’t matter if you have three or six meals a day. Calories do count and the total calorie intake is the important factor.
