When I first started using the pump I put on 12 pounds within a month. I have since lost 14 and am struggling to put it back on. I am 5' 7 1/2" tall and only weigh 118. I have always been slim but the weight gain that I initially experienced felt wonderful. How do I keep it on? I am on a high calorie low carb diet, doing yoga and nothing is helping. It has been a struggle to get my A1C down as well.
