The Claim

Structured aerobic exercise in sedentary, overweight middle-aged men does not reduce nonprescribed physical activity energy expenditure and may even increase it.

Source: Nonprescribed physical activity energy expenditure is maintained with structured exercise and implicates a compensatory increase in energy intake.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect

In plain English

In sedentary, overweight middle-aged men, structured aerobic exercise does not reduce other daily physical activity and may increase it.

See the scientific wording

Structured aerobic exercise in sedentary, overweight middle-aged men does not reduce nonprescribed physical activity energy expenditure and may even increase it, contradicting the hypothesis that exercise triggers compensatory behavioral inactivity.

Why this might work

When a person exercises regularly, their body burns fat, which lowers a hormone called leptin. Lower leptin tells the brain that energy is running low, so the brain keeps the person moving throughout the day instead of slowing down. This keeps daily movement levels high or even increases them, even though the person is burning more calories from exercise.

  1. Study: Nonprescribed physical activity energy expenditure is maintained with structured exercise and implicates a compensatory increase in energy intake.

    When overweight middle-aged men started a regular exercise routine, they didn’t become lazier the rest of the day — they kept moving about the same, or even a bit more. Their bodies didn’t slow down to ‘save energy’ after working out.
