how do i safely gain weight previously loss as result of illness . approx 14lbs lost. I am now 123lbs. would like to be back at 130 or so, so that my clothes fit and i feel better about my size. i had uterine embolization and of course the tumors have decreased in size but i lost several pounds due to not eating after and lack of appetite for a week or more. i am now eating alot and snacking in between meals and drinking ensure/boost drinks. note: safely..not junk food. thanks in advance.
