Hello sir, Good morning, I read your history... Coming to directly on your problem of weight gain... For that first of all you have modify your lifestyle first...I guess you have sedentary life style...so first of all be active... First start with mild to moderate exercise n after some time you should modify your diet plan also this will help you in weight reduction... Note that instant weight rrduction is harmful to body...n ideally weight rrduction is slow process so you have to keep pateint... So I suggest you consult gym professional or dietician for that... In addition please take care of your body n be regular for hiv medication... Best of luck... Thank you... Regards, Dr.Ravi Kotecha
