New here, trying to gain weight

I know, this is pretty unusual, and I've been heavy most of my life. I'd managed to lose 30 lbs the old fashioned way and was down to 180 lbs. A cancerous polyp was then found in my stomach, and the surgeons removed the lower 80% of my stomach and surrounding lymph nodes. Biopsy of the tissue found that there was no cancer other than the polyp removed during the initial endoscopy. I was very lucky there, and didn't have to go through chemo or radiation.

However, multiple complications and two years later, I've finally figured out what I can and can't eat. Bariatric surgery dietary suggestions don't work for everyone. I can eat tons of cheese, but can't drink milk or use cream or eat ice cream. I can't handle more than about 5 grams of sugars (regardless of the source) per serving of food. I also don't get hungry, but I have finally recovered my apetite. Mostly, I eat because I should. I'm back to cooking, but living alone, it's been a challenge cooking small amounts, since I don't have alot of freezer space.

Oh, and I'm up to a whopping 108 lbs. I have next to no muscle mass. The arms I used to hide because they were fat, I now hide because they're scrawny. After feeling crummy and being parked in my recliner all of this time, I'm working on building up my stamina and strength.

Anyway, here I am! I'm loving the app on my Droid. Scanning in items makes it so easy to track what I'm eating.
