A retrospective cohort study of 304 adults (aged 20-74) found that while no-exercise, aerobic training (AR), and resistance training (RT) all led to similar total weight loss on a calorie-restricted diet, the quality of that loss varied drastically. Participants in the RT group were the only ones to experience true body recomposition—simultaneously losing significant fat mass while actually gaining fat-free mass (averaging +0.8 kg in men and +0.9 kg in women). In contrast, those who did no exercise or only aerobic exercise lost substantial muscle mass along with their fat. Notably, RT produced the greatest reduction in abdominal circumference, a key marker for cardiometabolic health.
