The Claim
In trained individuals, the consumption of an additional 54 grams of casein protein per day, either in the morning or evening, does not result in increased fat mass over an 8-week period, even in the absence of changes in exercise volume, indicating that excess protein calories may not be efficiently stored as fat in this population.
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 you're someone who works out regularly, adding 54 grams of casein protein to your daily diet—whether in the morning or at night—won’t make you gain fat over 8 weeks, even if you don’t change your exercise routine.
See the scientific wording
In trained men and women, consuming an additional 54 grams of casein protein daily—either in the morning or evening—does not lead to increases in fat mass over 8 weeks, even without changes in exercise volume, suggesting that excess protein calories are not readily stored as fat in this population.
What the research says
1 studyStudy: Casein Protein Supplementation in Trained Men and Women: Morning versus Evening
The study gave people 54 grams of casein protein every day for 8 weeks and found they didn’t gain fat, even though they didn’t exercise more. This supports the idea that extra protein doesn’t turn into fat in trained people.
