I've had problems gaining and maintaining weight since I had UC and my colon was removed in my early 20's. I'm now 48 yrs old and still cannot budge over 125lbs. My so-called "ideal weight" should be around 135-140lbs. For those who say "just eat more", that doesn't work. For years I was accused by doctors of having anorexia because I had gotten down to 86 lbs at one point. It is so frustrating when people suggest just eat, eat, eat....it's not always easy to force feed yourself, just like I'm sure it isn't easy for those who are overweight to just stop eating. I know people mean well, but still!
I agree with the other post about eating peanut butter. I try to eat a lot of protein and carbs, and I also drink GNC mass gainer in order to add a little extra calories to my regular daily intake. I can't make the calorie shakes with the recommended amount of powder because it tastes too much like Ensure (which I learned real fast to detest after forcing myself to drink when I was sick), BUT, I figure that any extra calories are better than none. Mix with milk instead of water if you decide to try it. Good luck gaining! Don't forget that the large intestine weights about 4 or 5 lbs. I try to remind myself of that when I get discouraged about never seeing the 130's again.
