Untold millions have been spent in weight-loss crazes and fat-burning drugs, but it appears a diet high in protein might have the same metabolic effect, according to a study by The Veterinary and Agricultural University in Copenhagen, Denmark.

Researchers gave a group of 12 subjects three different meals: Two replaced about 20% of the carbohydrates in subjects’ diets with either pork or soy protein, and the third lowered the protein content in favor of more carbs.

Researchers then measured subjects’ 24-hour energy expenditures, and found that the pork and soy results showed about a 3% greater thermogenic effect than the carbohydrate diet, with pork producing a slightly greater effect than soy.

More encouraging still for carnivores is the mounting evidence that protein-rich meals lead to a greater feeling of fullness, and therefore fewer calories are consumed.
