i am about 6 weeks post surgury and i lost about 55lbs, i walk every day and exercise everyday but i hit a platue. my cal. intake is about 1000-1200 a day. i went to gnc today and was looking for protien bars and the employee there was telling me about l-carnitine and told me that would be a great thing for me to take becouse i was on a low cal. diet. i ama 6ft tall man that is currently about 240lbs..has anybody got any info whether or not this is good for people who had this surgury.
