The Claim

In normal-weight adults who have undergone diet-induced weight loss of 3% to 6%, absolute carbohydrate oxidation rates are lower at rest and during walking exercise compared to pre-weight-loss baselines, indicating a shift in fuel utilization during energy-deficient states.

How it works
1 study reviewed
In plain English

When normal-weight adults lose 3% to 6% of their body weight through dieting, their bodies burn less carbohydrate for energy while resting and walking, showing a change in how fuel is used during calorie deficit.

See the scientific wording

After diet-induced weight loss of 3% to 6% in normal-weight adults, absolute carbohydrate oxidation rates decrease at rest and during walking exercise, indicating a shift in fuel utilization during energy-deficient states.

Why this might work

When the body loses weight from eating less, it has less sugar available for energy, so it switches to burning more fat instead. This change makes movement more efficient and uses less total energy. At the same time, fat tissue shrinks and releases less of a hormone that tells the brain the body has enough energy. The brain responds by lowering energy use during activity to conserve resources.

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

    When normal-weight people lose a small amount of weight by eating less, their bodies start using less sugar (carbs) for energy, both when they're resting and when they walk. The study measured this and found it really happens.
