The Claim

In young healthy men, a 50% increase in energy intake during positive energy balance significantly increases resting metabolic rate, independent of changes in physical activity.

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.

Cause and effect

In plain English

When young healthy men consume 50% more calories than they burn, their resting metabolic rate rises, even if their physical activity levels stay the same.

See the scientific wording

In young healthy men, a 50% increase in energy intake during positive energy balance significantly increases resting metabolic rate, independent of changes in physical activity, suggesting energy intake modulates basal metabolic demands.

What the research says

1 study

  1. Study: Effects of increased energy intake and/or physical activity on energy expenditure in young healthy men.

    When young men ate 50% more food but stayed inactive, their bodies burned more calories at rest—meaning eating more makes your body work harder just to stay alive, even without exercise.
