Volumetrics (VM) is a dietary philosophy championed by Barbara Rolls, professor of nutrition at Penn State, that a key to weight management lies in controlling the energy (caloric) density of foods consumed.
Per Rolls, one should choose Category 1 (high-volume, low-calorie) foods–e.g., broccoli, carrots, celery, tomatoes, etc., which fill one up and thus trigger satiety more quickly, over Category 4 (low-volume, high-calorie) foods–e.g., crackers, crisps (chips), chocolate candy, cookies, nuts, butter, and oil.
Pros It is heart healthy, diabetes friendly, based on sound dietary principles, and has the blessings of the CDC–Centers for Disease Control and Prevention.
It makes sense…people eat less when they feel full.
