Influence of exercise and calorie restriction on obese rats was studied using MR imaging and spectroscopy. The rats were fed with high fat diet D12079B. Animals were grouped (n=7/group) as control, calorie restriction (mild and severe) and exercise (mild and severe). All experiments were performed on a 7T MRI/MRS scanner. Rats were scanned at pre- and post-intervention stages. Calorie restriction and exercise group showed significant reduction in SAT, VAT and liver fat and was correlated to the blood analysis.
