The Claim

In resistance-trained female collegiate athletes, the consumption of 24 grams of protein immediately before and after resistance training sessions, combined with a supervised 4-day per week undulating periodized resistance training program over eight weeks, causes significant increases in lean body mass (approximately 1.4–1.5 kg) and significant reductions in body fat percentage (1.0–2.0%) as measured by dual-energy X-ray absorptiometry (DXA).

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.

Cause and effect
1 study reviewed
In plain English

If female college athletes who already lift weights drink a protein shake with 24 grams of protein right before and after their workouts for eight weeks — while following a specific 4-day workout plan — they’ll likely gain about 1.4 to 1.5 kg of muscle and lose 1 to 2% body fat.

See the scientific wording

In resistance-trained female collegiate athletes, consuming 24 grams of protein immediately before and after resistance training sessions for eight weeks, in combination with a supervised 4-day per week undulating periodized training program, causes significant increases in lean body mass by approximately 1.4–1.5 kg and significant reductions in body fat percentage by 1.0–2.0% as measured by DXA.

  1. Study: The effect of resistance training combined with timed ingestion of protein on muscle fiber size and muscle strength.

    The study gave female college athletes 24 grams of protein before and after workouts for 8 weeks and found they gained about 1.4–1.5 kg of muscle and lost 1–2% body fat, just like the claim says.
