The Claim
Mixed training (combined strength and endurance) preserves 1.20 kg more fat-free mass than calorie restriction alone in overweight or obese adults, and this effect is the largest observed among exercise modalities in this analysis.
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 overweight or obese adults, combining strength and endurance exercise preserves 1.20 kilograms more fat-free mass than calorie restriction alone, and this difference is the largest among all exercise types studied.
See the scientific wording
Mixed training (combined strength and endurance) preserves 1.20 kg more fat-free mass than calorie restriction alone in overweight or obese adults, which is the largest effect observed among exercise modalities in this analysis.
When a person does both weightlifting and cardio while eating fewer calories, the physical stress from lifting weights turns on signals that tell muscles to build more protein, and the cardio keeps the energy factories in muscle cells working well. Together, this stops the body from breaking down muscle even when it doesn't have enough energy, preserving more muscle mass than either type of exercise alone.
What the research says
1 studyWhen people who are overweight diet, they often lose muscle too—but adding both weightlifting and cardio helps them keep about 1.2 kg more muscle than just dieting alone, more than either type of exercise by itself.
