MRI and MRS allow for the investigation of changes in fat metabolism by exercise/dietary intervention in liver, muscle and abdominal fat (subcutaneous (SAT) and visceral (VAT)). In this study, we investigated the changes in fat distribution pre- and post-weight loss intervention in overweight Chinese men. The 16-week weight loss program consisted of three 90-min exercise sessions per week and a diet comprising of a caloric deficit of upto 1000 kcal. The results showed significant gain in fat depots post-weight loss except for IMCL. Further, the increase in SAT, VAT and %body-fat revealed significant correlations with the increase in insulin sensitivity.
