The Claim
In overweight or obese adults, the addition of structured exercise to calorie restriction reduces fat-free mass loss by an average of 0.87 kg compared to calorie restriction alone.
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.
When overweight or obese adults cut calories and add structured exercise, they lose 0.87 kilograms less lean tissue than when they cut calories alone.
See the scientific wording
Adding any form of structured exercise to calorie restriction in overweight or obese adults reduces fat-free mass loss by an average of 0.87 kg compared to calorie restriction alone, preserving lean tissue critical for metabolic health and physical function.
When a person does strength exercises while eating fewer calories, the pulling force on muscles turns on a molecular signal that tells the body to build more muscle proteins. This stops the muscle from breaking down even though the body has less energy available.
What the research says
1 studyWhen people who are overweight eat less to lose weight, adding exercise helps them keep about 0.87 kg more of muscle and lean tissue than if they only eat less—this study proves it with solid data.
