When you're dieting, you may find your weight-loss plan restricts carbohydrates and fat. However, that does leave you with room for protein in your diet. There is a wide variety of protein-based diet supplements available, as protein is purported to have benefits for weight loss. According to a study published in the March 2008 issue of the journal "Nutrition & Metabolism," protein-based supplements may induce significant improvements in fat loss when used during a reduced-calorie diet. You should consult a doctor before beginning a weight loss plan or using any supplements.
ABB Pure Pro Shot
The ABB Pure Pro Shot is a low-calorie, pre-made protein shake that contains very little carbohydrates and fat. Each ABB Pure Pro Shot shake contains 30 g of protein, 1 g of carbohydrates and .5 g of fat. The main ingredient in the ABB Pure Pro Shot is whey protein isolate, which is a protein source derived from dairy. When used as part of a reduced-calorie diet, according to research from the October 2006 issue of the "International Journal of Sport Nutrition and Exercise Metabolism," whey protein isolate in conjunction with exercise produces greater losses in fat than exercise alone.
Nutrabolics Isobolic
Nutrabolics Isobolic is a low-carbohydrate, low-fat protein powder supplement. One serving of Isobolic contains 110 calories, 1.5 g of fat, 2 g of carbohydrates and 22 g of protein. Unlike many protein supplements that contain just one source of protein, Isobolic contains whey, egg and casein protein, which each has a different rate of digestion. This can keep amino acids moving through your body for an extended period of time.
In addition to these protein sources, Isobolic also contains essential fatty acids and conjugated linoleic acid, which may have weight-loss benefits. Research published in the August 2004 issue of the "International Journal of Obesity and Related Metabolic Disorders" says some studies indicate conjugated linoleic acid can improve weight loss, although results in other studies are mixed.
VPX Protein Rush
VPX Protein Rush is a ready-to-drink protein supplement intended for use as a meal replacement. Each VPX Protein Rush shake contains 240 calories, 5 g of fat, 9 g of carbohydrates and 40 g of protein. These low-carbohydrate shakes also contain 4 g of fiber, which may help you feel full and encourage you to reduce your calorie consumption. Like Isobolic, VPX Protein Rush contains a blend of different protein sources, including whey protein isolate and whey protein hydrolysate. In addition to weight loss, whey protein hydrolysate may improve exercise performance -- a study from the January 2010 issue of the "Journal of Science and Medicine in Sport" found whey protein hydrolysate may enhance recovery from exercise.
