No specific diet (keto, fasting, vegan, etc.) is superior to others for long-term weight loss; the best diet is simply the one you can stick to over time.

The idea that adherence is the determining factor for success is widely supported by current scientific literature. A major meta-analysis published in the JAMA (Johnston et al.) compared various popular diets and concluded that differences in weight loss between them are minimal, emphasizing that the caloric deficit is the primary driver, regardless of the chosen method. Observational studies and randomized controlled trials (RCTs) consistently confirm that an individual's ability to maintain their dietary habits is a better predictor of success than the macronutrient composition of the diet. What may be considered a simplification is the idea that all diets are strictly equivalent for metabolic health, as the nutritional quality of foods remains crucial independently of weight loss. In short, Layne Norton highlights a pragmatic truth: behavioral sustainability outweighs perfect nutritional theory. The approach is scientifically robust because it recognizes the limitations of human adherence in the face of restrictive protocols.
