For men new to weightlifting, eating protein and carbs right after a workout or waiting six hours doesn't change protein retention in the body.

Scientific Claim

Untrained young men (n=10, age 23±1 years) showed no significant difference in nitrogen balance between immediate (1.3 ±0.1 g/24h) and 6-hour delayed (1.2 ±0.2 g/24h) protein and carbohydrate intake after resistance exercise.

Original Statement

“that in the untrained men was not significantly different between the two periods.”

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

RCT design allows definitive statements about the lack of effect in this specific population. The claim accurately reflects the non-significant result without implying causation where none exists.

Similar Assertions

Experienced weightlifters retain less protein in their bodies after workouts compared to beginners, regardless of when they eat protein and carbs.

96%

For men who regularly lift weights, eating protein and carbs right after working out leads to better protein retention in the body compared to waiting six hours.

93%

For experienced lifters, eating protein and carbs right after a workout leads to better protein retention per pound of body weight than waiting six hours, but this isn't the case for beginners.

90%

Experienced weightlifters lose over half their protein retention per body weight when delaying protein and carb intake after a workout, but beginners aren't affected much by the timing.

Eating a big protein meal (100g) after working out keeps your blood amino acid levels high for the whole 12 hours, while a smaller meal (25g) only keeps them high for the first 5 hours.
