The Claim
In elderly men aged 60–80 years, two weeks of lower limb immobilization results in significant reductions in quadriceps muscle mass and strength, and these deficits are fully restored within two weeks of retraining when combined with daily whey protein supplementation (2 × 20 g/day), indicating that short-term rehabilitation with protein support can rapidly reverse disuse-induced muscle loss.
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 older guys between 60 and 80 don’t use their legs for two weeks, they lose leg muscle and strength—but just two weeks of exercise plus drinking protein twice a day can bring it all back.

What the research says
1 studyThe study found that older men lost leg muscle after two weeks of not using it, but got it all back after two weeks of exercise and drinking protein shakes, just like the claim says.
