The Claim
In trained individuals consuming approximately 2.4 grams of protein per kilogram of body weight per day, the addition of 54 grams of casein protein supplementation either in the morning before 12:00 PM or in the evening within 90 minutes of sleep for 8 weeks does not significantly affect body composition, including fat mass, fat-free mass, or percent body fat, when training volume is held constant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If fit people already eat a lot of protein, taking extra casein protein in the morning or before bed doesn’t change their body fat or muscle over 8 weeks—if their workouts stay the same.
See the scientific wording
In trained men and women consuming approximately 2.4 grams of protein per kilogram of body weight per day, supplementing with 54 grams of casein protein either in the morning before 12:00 PM or in the evening within 90 minutes of sleep for 8 weeks has no significant effect on body composition, including fat mass, fat-free mass, or percent body fat, when training volume is unchanged.
What the research says
1 studyStudy: Casein Protein Supplementation in Trained Men and Women: Morning versus Evening
The study looked at whether taking 54 grams of casein protein in the morning or at night changes body fat or muscle in people who exercise regularly. It found no difference, which supports the claim.
