Why Use Protein Powder?
Protein powder supplements are popular supplements for strength-training athletes, bodybuilders and other active individuals, but they can be useful for anyone. The supplements are high in protein and tend to be low in carbohydrates and fat, which can make them appropriate for a range of dietary needs. While protein supplements may promote health benefits, check the labels closely, as nutrition facts vary among brands. Consult a doctor before using any supplement.
Protein powder can be a convenient alternative to other high-protein foods such as meat and fish, as those take longer to prepare. Another benefit protein powder provides compared to such foods is that may be a better way to control your appetite. A study from the October 2010 edition of "The British Journal of Nutrition" found that consuming whey protein provided more satiety than turkey, eggs and fish, and resulted in reduced calorie intake later in the day.
Although consuming protein shakes after workouts is popular, drinking your protein powder before you exercise may help you lose weight. A study published in the May 2010 issue of "Medicine and Science in Sports and Exercise" found that drinking whey protein before a workout resulted in an increased rate of calorie burning for the entire day following the workout.
Improved Future Performance
One way in which protein powder can be helpful is that it promotes recovery from your workouts. Resistance training puts stress on your body, and you may feel weaker in future workouts if you do not provide your body with the proper nutrients for recovery. Research from the May 2011 issue of the "Journal of Strength and Conditioning Research" suggests that consuming a shake made of protein and carbohydrates after workouts can help you maintain a high-level of performance in future training sessions.
Increased Muscle Size
Whether you're a professional bodybuilder or just an active individual trying to look and feel healthy, increasing your muscle size can be beneficial. While resistance training provides a stimulus for muscle growth, protein is required to increase size. Research from the June 2010 issue of "Nutrition & Metabolism" suggests that whey protein powder is more effective than other types of protein for increasing muscle size when combined with weight training.
