The Claim
Home-based resistance training during dietary weight loss in adults with overweight or obesity does not significantly preserve fat-free mass or muscle thickness, as measured by bioelectrical impedance and ultrasound, despite improvements in muscle function.
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 adults with overweight or obesity who are losing weight through diet, doing resistance training at home does not prevent loss of fat-free mass or muscle thickness, even though muscle function improves.
See the scientific wording
Home-based resistance training during dietary weight loss in adults with overweight or obesity does not significantly preserve fat-free mass or muscle thickness, as measured by bioelectrical impedance and ultrasound, despite improvements in muscle function.
When someone does resistance exercises at home while losing weight, their nervous system gets better at turning on muscle fibers more efficiently. This makes them stronger and able to do more repetitions, but their muscles don't get bigger because the body isn't building new muscle tissue.
What the research says
1 studyWhen people with extra weight lose weight by eating less, adding home workouts makes them stronger but doesn’t stop them from losing muscle—just like how a car can run better after a tune-up without getting heavier.
