Mehmet Oz on sugar as the real weight driver: warns against

Dr. Mehmet Oz warns against sugar, arguing that fat is not the real culprit in obesity. Oz told Fox News Digital in February 2026: “Paradoxically, it’s not eating fat that makes you fat. It’s sugar that makes you fat.”

Oz’s stated reasoning is that sugar — not dietary fat — drives weight gain, which is why he backs the new guidelines’ protein-forward, healthy-fat approach and eased-up stance on saturated fats. (This is Oz’s stated position, not medical advice.)
