Warburg-effect diet claims ('sugar feeds cancer')
Because cancer cells burn a lot of glucose, many people conclude that cutting sugar starves tumours. The biology is real; the conclusion is not. Blood glucose is tightly regulated and no trial shows sugar restriction improves cancer outcomes.
Otto Warburg's observation that tumours favour aerobic glycolysis underpins FDG-PET imaging and legitimate metabolic-therapy research (glutaminase, IDH, PI3K inhibitors). It is also the basis of popular claims that sugar-free, ketogenic or 'anti-cancer' diets can treat cancer. The gap: dietary sugar intake changes blood glucose only transiently in non-diabetics; tumours also use glutamine, lactate, fatty acids and ketones; and randomised evidence for dietary glucose restriction as therapy does not exist outside small feasibility trials. What is supported is avoiding hyperglycaemia and obesity, which raise insulin and IGF-1, and treating diabetes well during cancer therapy. This term exists so the site can link honestly to both the science and the myth.
