#1228 Higher Protein Diet

Our studies, suggested that those people on a higher protein diet lost the same amount of weight as those on a higher carbohydrate diet, since the two diets offered an ___ amount of kilojoules and the same amount of fat. However, body composition (that is, the ratio of fat to muscle) ___ greater improvement among those people on the higher protein diet. When the participants in our studies were allowed to eat until they were no longer hungry, those on the higher protein diet lost more weight than those on the higher carbohydrate diet, even after more than a year. The reduction in hunger and the beneficial effect on muscle supplied by the higher protein diet is mostly related to its protein content. The diet is healthy because its protein comes from lean red meat, fish, chicken and low-fat dairy products, all of which ___ good nutrition. A high-protein diet in which the protein comes from protein powders and supplements is unlikely to be healthy, unless the supplements are fortified with vitamins and minerals.
