Well, I just typed this into Google: study lose weight by changing macro nutrients while maintaining the same caloric intake https://academic.oup.com/ajcn/article/79/5/899S/4690223 https://academic.oup.com/ajcn/article/79/5/899S/4690223 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5639963/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5639963/ https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0057300 https://journals.plos.org/plosone/article?id=10.1371/journal... I only very, very briefly skimmed these, and am not claiming they refute your claim. Having said that, I know one person who lost a great deal of weight even while consuming more calories, over the course of a number of years, and given no substantial delta in exercise. To a first, broad approximation, it's true: people who fewer calories will tend to lose weight. But this is an exceptionally complicated topic, and I posit that most any generalizations tend to do more harm than good, if taken too deeply.
