Hi everyone! I'm looking for some advice on how to gain weight. I'm an 18 year old guy and currently weigh about 118lbs and am 5' 9". I recently had 3 C-diff infections since November and went down to about 112lbs, so I've gained some weight, but still have a ways to go. I've been drinking Ensure Plus and started working out to build muscle. I also asked the doctor about whey protein and she said it's safe to take as long as I don't overdo it. Anyone have any tips or suggestions on how I can gain weight? I start college in the fall and would like to gain 15 - 20 lbs by the end of the summer. Thank you in advance for any advice!
