The Claim
In healthy young men, a 12-week combined endurance and strength training program increases total daily energy expenditure by approximately 1.13 MJ/day, as measured by doubly labeled water, with a significant portion of this increase attributable to elevated resting energy expenditure from gains in fat-free mass.
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 young men, a 12-week program of combined endurance and strength training raises total daily energy expenditure by about 1.13 megajoules per day, primarily due to increased resting energy expenditure from added fat-free mass.

Lifting heavy weights causes muscle fibers to grow larger, and this extra muscle tissue burns more calories even when the body is at rest, which raises the total amount of energy used each day.
What the research says
1 studyAfter 12 weeks of working out with both cardio and weights, healthy young men burned about 1.13 megajoules more energy each day — and part of that boost came from having more muscle, which burns more calories even at rest. The study measured this accurately using a trusted method.
