Carnivore An elimination diet taken to its endpoint. Its strongest case is as a diagnostic tool for people with severe autoimmune or gut symptoms who have run out of variables to remove — not as a permanent way of eating for everyone. These pages cover what the reported results actually consist of and the real questions about long-term nutrient sufficiency. Keto A ketogenic diet is a metabolic intervention, not a weight-loss trend. Restricting carbohydrate far enough to shift the body onto fat and ketones changes insulin, appetite signalling and, in some conditions, seizure threshold and cognitive symptoms. These pages cover how it is done properly, what happens in the first weeks, and where the evidence is strong versus merely promising. Mediterranean The most consistently supported dietary pattern in the epidemiological literature, and the most frequently misrepresented. What the studied populations ate bears little resemblance to the pasta-and-olive-oil version sold in its name. These pages cover the pattern as it was actually observed and which components carry the effect. Whole Foods Not a diet but the precondition for any of them working. Almost every eating pattern with evidence behind it removes the same things: refined flour, industrial seed oils, and sugar in liquid form. These pages cover what changes when food is simply food again, and why that alone accounts for much of what gets attributed to specific diets.
