It's largely because people don't understand that the body will do everything possible to not lose fat due to insulin mismanagement. The only way to legitimately say "weight loss happens in the kitchen" if the discussion is over what, and how often... any discussion that is about CICO throws something like 20 years of science under the bus. HIIT helps override early metabolic syndrome symptoms, but so does eating a diet devoid of refined sugars, refined grains, and seed oils; combining this with a high fat diet (to purposefully keep insulin levels low) multiplies the effect of both HIIT and diets that follow the Paleo way of thinking; then, on top of those, One Meal A Day (OMAD) further multiplies the effect. If you eat your TDEE in calories every day (ergo, neither excess nor deficit of calories), you will lose weight with HIIT, but also lose weight with Paleo, more weight adding Keto to Paleo, and then even more weight with Ketoized Paleo OMAD, and all four together would still be a weight loss powerhouse even with eating TDEE.
