Thank you for your question.I would not recommend taking any type of thermogenic or weight loss stimulant. Many are not even FDA approved and only consist of high doses of caffeine and can cause blood thinning. I would recommend following a balanced healthy lifestyle through diet and exercise, it is much safer and healthier for your body but make sure to be cleared by your surgeon before you start back into any sort of exercise routine.
Best of luck in your recovery!
