Gnc Products That Make You Gain Weight

GNC is a company that produces and sells sports nutrition supplements such as protein supplements and weight-loss pills. Although many products made by GNC are purported to aid in weight loss, some may also help you gain weight if you consume more calories than you burn each day. Despite the potential benefits, you should consult a doctor before using any supplements.

Pro Performance Mass XXX

GNC's Pro Performance Mass XXX is a high-calorie, protein-rich supplement that can help you gain weight. Each serving of this supplement contains 750 calories, which is more than 37 percent of the daily suggested intake of 2,000. This supplement can help you gain weight because it supplies more calories than you'd burn in a workout. MayoClinic.com notes that an hour of weightlifting burns 219 calories, while an hour of jogging burns 584.

Pro Performance Lean Muscle Meal

Lean Muscle Meal is a product intended to be a high-protein snack or meal replacement. However, it may not be as beneficial for weight gain as other supplements, as it contains 260 calories, with 40 g of protein. The protein comes from whey, which research from the June 2010 issue of "Nutrition & Metabolism" explains can increase muscle protein synthesis, which drives muscle growth, more than other types of protein.

Pro Performance Oatmeal Protein Bar Deluxe

GNC's Pro Performance Oatmeal Protein Bar Deluxe is a high-calorie nutrition bar that is rich in protein and complex carbohydrates. Each bar contains 390 calories, with 12 g of fat, 49 g of carbohydrates and 30 g of protein. The bar is rich in fiber, with 5 g, which could be detrimental for weight gain, as the nutrient helps promote increased satiety.

Pro Performance Hyperbolic Mass Gainer Bar

GNC's Hyperbolic Mass Gainer bar can be an effective supplement for weight gain, as it is high in calories. Each bar provides 530 calories, with 51 g of carbohydrates and 45 g of protein. The bar is also high in fat, with 19 g per bar, which can help you gain weight. Research published in the June 1997 issue of "International Journal of Obesity and Related Metabolic Disorders" indicates that fat is less filling than other nutrients, so it can aid in weight gain.
