The Claim
In overweight postmenopausal women undergoing weight loss, a high-protein diet has no effect on overall physical function as measured by the Short Physical Performance Battery or 400-meter walk time, despite a potential improvement in handgrip strength.
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.
For overweight women after menopause who are losing weight, eating more protein does not improve their ability to walk, stand, or move quickly, even if it may increase hand strength.
See the scientific wording
In overweight postmenopausal women, a high-protein diet during weight loss does not improve overall physical function as measured by the Short Physical Performance Battery or 400-meter walk time, despite a potential benefit in handgrip strength.
When overweight postmenopausal women lose weight on a high-protein diet, their muscles keep making more protein, which keeps their hand strength strong. But their legs and balance don't get better because the body doesn't increase muscle size or nerve signals in the legs, and fat loss doesn't reduce the extra load on the hips and knees enough to improve walking or balance.
What the research says
1 studyIn overweight women over 50 losing weight, eating more protein didn’t help them walk faster or balance better, even though it helped keep their hand strength from getting weaker.
