It was an honor to co-author the International Society of Sports Nutrition position stand evaluating the scientific evidence on dietary strategies for weight loss and body composition (PMID: 42867412). Huge kudos to @thealanaragon for spearheading the effort. Some key takeaways: --Calorie deficit is king: Weight loss is primarily driven by sustained energy restriction, with dietary approaches best tailored to individual preferences and goals. --Intermittent fasting isn't superior: Time-restricted eating and other fasting strategies generally produce similar weight and fat loss compared with continuous calorie restriction. --Carb vs fat ratios are overrated: Both lower-carbohydrate and lower-fat diets can be similarly effective for fat loss. Ketogenic diets may lead to greater reductions in fat-free mass, but this appears to be partly attributable to changes in glycogen/water stores. --Protein matters: Intakes of 1.2–1.6 g/kg/day are appropriate for the gen pop, while 1.6–2.2 g/kg/day may optimize muscle anabolism when combined with resistance training. Higher intakes may benefit lean, resistance-trained individuals dieting in a caloric deficit. --Lift weights to preserve muscle: Resistance training combined with adequate protein intake is essential for minimizing lean mass loss during weight reduction. --Meal frequency is flexible: Eating more frequently does not inherently enhance fat loss, although distributing protein across at least three meals daily may benefit muscle retention and performance. --Aggressive dieting isn't necessarily better: Very-low-calorie diets can accelerate short-term weight loss but offer no clear long-term advantage and may increase the risk of muscle loss and nutrient deficiencies. --Metabolic adaptation is real: Energy expenditure can decline during weight loss, sometimes beyond what is predicted by changes in body composition. However, these adaptations aren’t inevitable and may diminish with weight stabilization. Bottom Line: There is no universally superior diet for fat loss. The best approach is one that creates a sustainable calorie deficit, provides sufficient protein, incorporates resistance training, and aligns with individual preferences to promote long-term adherence. tandfonline.com/doi/full/10.…
