You sound like you have a great attitude and a firm Christian faith to fall back on. I grew up on way too much white sugar, it is my downfall. My college aged kids are both healthy, but they have to pay attention to their weight. My daughter is normal size, but has to work at it, and is on synthroid for her thyroid since high school. My son is overweight, but he and his girlfriend have been attending weight watchers for last few months, and with this being his last and easiest semester of undergrad, he has signed up for a bowling league, plus 2 aerobics classes, so that should help a lot.
