A new study published in Nature Medicine reveals that individuals lost more weight and unhealthy fat on a minimally processed diet compared to a nutritionally similar ultra-processed diet over six months. Participants in the UCL-led trial swapped diets after eight weeks. While both diets resulted in weight loss, the minimally processed diet led to a greater reduction (2% vs 1%) and more fat loss. Researchers suggest ultra-processed foods' appealing textures and flavors may contribute to increased cravings, hindering weight loss. The study emphasizes the need for societal changes to improve access to healthy, affordable diets.
