The Claim

Increasing physical activity by 50% in young healthy men significantly raises total energy expenditure, independent of changes in energy intake, demonstrating that physical activity is a primary driver of energy expenditure in this population.

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

In plain English

When young healthy men increase their physical activity by 50%, their total energy expenditure rises significantly, even if their food intake does not change, indicating that physical activity has a major influence on how much energy the body uses.

What the research says

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

    Scientists made young men move 50% more without letting them eat more, and their total energy use went up — proving that moving more burns more calories, even if you don’t change what you eat.
