Robert Lustig on the 'A Calorie Is a Calorie' Model: warns against

Dr. Robert Lustig warns against the “a calorie is a calorie” model of nutrition. He calls the calorie and cholesterol hypotheses “dead,” arguing that the real culprit in chronic disease is insulin resistance and that different foods have different metabolic effects regardless of calorie count.

His stated reasoning is that what matters is a food’s hormonal and metabolic impact — particularly on insulin and the liver — rather than its energy content alone. This is Lustig’s stated position; the calorie model remains the mainstream framework, and Lustig’s rejection of it is contested.
