A UK study found that people who cook minimally processed meals at home lose more weight than those consuming ultra-processed meals, even if the latter are healthy. The study involved 55 adults and showed that while both diets met health guidelines, participants on minimally processed diets lost twice as much weight. Experts suggest that while ultra-processed foods aren't entirely detrimental, a focus on minimally processed foods can enhance health outcomes. The study highlights the need for policy changes to address the availability of unhealthy food options.
