Yes, but protein powders come in a multitude of formulas.
To remain MetPro compliant select one that is almost straight protein and low in carbs and fat. Up to 3 grams of carbohydrates per 15 grams of protein (or 6/30 for 2 servings) is common and can be tracked as a typical protein source for a meal or snack. Formulas higher in carbs will make tracking complicated and therefore not recommended, particularly if fat loss is your selected goal.
Remember, protein powders aren’t as filling as other protein sources. If appetite control is an issue, avoid relying on them too much.
