The Claim
In healthy older men, 8 weeks of resistance training combined with protein intake of either 0.8 or 1.6 g/kg/day does not result in a significant change in body fat percentage.
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.
In healthy older men, doing resistance training and eating either 0.8 or 1.6 grams of protein per kilogram of body weight per day for 8 weeks does not change body fat percentage.
See the scientific wording
In healthy older men, resistance training combined with either 0.8 or 1.6 g/kg/d protein does not significantly alter body fat percentage, suggesting that fat loss in this population is not primarily driven by protein intake or resistance training over an 8-week period.
When older men lift weights, their muscles grow bigger because the protein they eat tells their muscle cells to build more protein and stop breaking it down. This makes their muscles heavier, but it does not change how much fat they have, because the body does not burn fat to fuel this process or because of the extra protein.
What the research says
1 studyIn older men who did weight training for 8 weeks, eating either the normal amount of protein or twice as much didn’t make them lose any body fat — so the training and protein didn’t cause fat loss in this time.
