How many calories are in Protein Powder?
Protein powders vary from brand to brand depending on additional additives, so the exact number of calories can be hard to work out. In general though, protein provides 4 calories per gram. So for a 30gram serve of reasonably pure protein powder, you can expect the calorie count to be approximately 120 calories. Of course you should stay clear of products with added sugar or fat content as this can increase the calorie count dramatically.
