I'm thin, always have been, but too can gain weight when it's cycling season. Most of it is muscle, but yeah I've been known to take in way more calories than I burned on a ride
This season I'm trying to be better about it, but we'll see.
Anyway, I'm 5'10 and a size 6 or 8 depending on where I'm at on the weight spectrum that I seem to go up and down. When you're this tall, it's easy to look that lanky thin that can be scary. I get downright boney sometimes, but I've never been "under weight" according to BMI standards, etc. And because I have crohn's I'm always keeping an eye on my weight which can slide off like crazy if I have a bad month or 2. You should hear some of the comments I've gotten, especially before I was more open about my illness. Now people know or I tell them why I've lost weight. But a lot of people assume you have some sort of eating disorder or the like. I agree that at the heart of the "you need to lose weight" or "you're too skinny" comments is this insecurity many people have about what's the ideal. But the definition of the ideal doesn't take into account other healthy habits like eating right and exercising. It's all about appearances.
