Comedian and former journalist Tom Naughton sets out to answer Super Size Me by eating fast food himself, but with a twist: he keeps his carbohydrate intake low, cuts out sugar and refined starch, and tracks his weight and blood work over the following weeks. The numbers move the opposite direction from what Morgan Spurlock's film predicted, and Naughton uses that result to build a case against the low-fat, high-carb advice baked into the USDA food pyramid for decades. He interviews doctors, researchers, and nutrition writers who question the lipid hypothesis linking dietary fat to heart disease, and walks through the studies he says got misread or oversold on their way to becoming public health policy. Animated bits and stand-up-style asides carry the argument between interviews, keeping the tone closer to a rebuttal than a lecture. The film's target is less fast food itself than the chain of scientific claims that turned into government guidelines, and it asks viewers to look at where those guidelines actually came from.
