Participants adhered to healthy diets for 18 to 24 months, including the Mediterranean diet, green Mediterranean diet, low-fat, and low-carbohydrate diets. The study found that across all clinical trials, 36% of participants achieved clinically significant weight loss, but many others experienced health benefits without losing weight. Nearly one-third of participants did not lose any weight at all, with 28% resistant to weight loss, yet they still reaped many health benefits, including a lower risk of diseases such as type 2 diabetes, hypertension, and cardiovascular conditions.
