The Claim

In premenopausal overweight and obese women on a 500 kcal/day calorie deficit, consuming 800 mg/day of calcium as calcium carbonate results in moderate weight loss of 3.89 kg, but this weight loss is less than that achieved with low-fat cow's milk consumption, indicating that calcium supplementation alone does not fully account for the fat loss benefits associated with dairy intake.

In plain English

In overweight and obese premenopausal women on a 500 kcal/day calorie deficit, taking 800 mg/day of calcium carbonate leads to 3.89 kg of weight loss, but less than the weight loss seen with low-fat cow's milk, meaning calcium alone does not explain all the fat loss benefits from dairy.

See the scientific wording

Why this might work

Milk contains proteins that break down into small molecules during digestion. These molecules signal fat cells to burn more fat and store less fat, which leads to greater weight loss than calcium alone can produce.

    When overweight women cut calories and either took calcium pills or drank low-fat milk, those who drank milk lost more weight than those who took pills—so milk must have something extra that helps you lose fat beyond just calcium.
