Direct answer: Onion receives a GREEN result in this DietVox Weight Loss comparison. The scope is plain raw, steamed, boiled or otherwise simply prepared Onion, not every possible product or recipe. A single food does not determine weight change; portions and the whole eating pattern matter. NHS healthy-eating guidance for weight loss frames the wider advice.
What the rating means here
The boundary of this result matters: Fried, creamed, pickled, dressed, sauced and blended preparations change the complete dish. Include oils, dressings and sauces in the serving being assessed.
