Comparison of two hypocaloric diets in obese children
Use of a protein-sparing modified fast (PSMF) diet among obese children appears to be a safe and rapid means of losing weight. Ten obese children followed a low-calorie PSMF diet (50% protein, 40% fat, and 10% carbohydrate). Nine obese children followed a diet of slightly higher caloric intake that was 20% protein, 30% fat and 50% carbohydrate. After 10 weeks all children were placed on the same maintenance diet (20% protein, 30% fat, and 50% carbohydrate). At 10 weeks, patients on the PSMF had lost an average of 11.2 kilograms (kg) while children on the other diet had lost an average of 5.1 kg. At six months, children on the PSMF diet had lost more weight than children on the other diet. Seven of 10 children on the PMSF diet completed the 14.5 month program compared with four of nine children on the other diet. Although most children had regained the weight at 14.5 months, children on the PSMF diet had lost more weight compared to their height.

The Atkins diet
The Atkins diet may not be effective in promoting long-term weight loss. Dr. Atkins created the high-protein, low-carbohydrate diet in the early 1970s. The diet can cause short-term weight loss because it creates a condition called ketosis. Ketosis in turn causes the body to excrete water. Water loss can cause weight loss, but the weight will return when the patient replaces the water. The diet does not suppress appetite, according to one study. The claim that it burns fat has also not been proven.

High protein, low carb diets: Are they right for you?
The apparent dramatic weight loss from high protein, low carbohydrate diets is often temporary. The limited food choice and extremely low calorie intake mean it is unhealthy as a long term diet.
