Before you answer the question, “Why is it bad to take protein shakes before bed?”, it is important to understand that not all protein sources are created equal. Protein shakes and other food sources contain different amounts of whey protein and casein protein. Casein protein is one of milk’s two types and makes up 80 percent of the protein content. Casein is a slow-digesting protein that may interfere with sleep quality.
While protein shakes are often associated with late-night consumption, they have been shown to have a positive effect on muscle recovery. They may support better muscle growth as well. A study conducted over 12 weeks found that people who consumed protein shakes in the late afternoon and evening had better recovery and growth of muscle tissue. While this may seem counterintuitive, it is still worth considering. It may be helpful to drink a protein shake before going to bed if you are following a weight loss program.
Research suggests that taking protein before bed can boost muscle growth by increasing muscle protein synthesis and releasing natural hormones like HGH. Studies have also shown that protein before bed does not cause weight gain and helps you burn more fat. A study conducted at Florida State University found that eating protein before bed did not impair fat metabolism, and it was even beneficial for people who wanted to increase muscle mass before bed.
