PROTEIN
Yes, protein shakes can make you fat, as too much protein consumption can lead to a surplus in the body. This disrupts the balance in the "fuel mix" and you are less likely to use fat as a fuel because of excess protein. You can grow fat by eating too much protein because excess protein can lead to fat storage. If you are taking protein shakes you must account for the increased protein and decrease other dietary protein intake to avoid making fat.
