Are all healthy diets equal or does food processing make a difference?

A randomized crossover trial in the UK found that both ultra-processed (UPF) and minimally processed food (MPF) diets, when aligned with national guidelines, led to weight loss in adults with overweight or obesity. However, the MPF diet produced significantly greater reductions in weight, fat mass, and food cravings, highlighting the added benefits of limiting food processing.
