There’s a perception among exercisers that you can suck down as many
protein shakes and chew through as many protein bars as you’d like without actually gaining weight.
However, the truth is that protein can actually hinder weight loss—through a process called gluconeogenesis.
Through gluconeogenesis, when you eat excess protein (even from “lean” sources like chicken, turkey, or protein bars) your liver very easily transforms that protein into sugar. And that sugar can then be converted into fat and deposited right on your waistline! Read more about how much protein you should consume here.
