The Claim

In normal-weight adults, a 3% to 6% diet-induced weight loss is associated with a significant reduction in exercise energy expenditure during walking, without changes in resting energy expenditure, suggesting metabolic adaptation may occur during weight loss in this population.

In plain English

In normal-weight adults, losing 3% to 6% of body weight through diet reduces the number of calories burned during walking, but does not change the number of calories burned at rest.

Why this might work

After losing a small amount of weight by eating less, the body burns less sugar during walking and relies more on fat for energy. This shift makes movement more efficient and uses fewer calories, even though the person walks the same way. The body does not change how many calories it burns at rest.

  1. Study: Energetic adaptations in response to moderate calorie restriction-induced weight loss in normal-weight adults.

    When normal-weight people lose a few percent of their weight by eating less, their bodies become more efficient at walking — meaning they burn fewer calories doing the same walk. Their resting calorie burn doesn’t change, but their body saves energy during movement, which might make it easier to gain weight back.
