I think you're slightly underweight sugahorse. I've always been slim - I'm 5'6 inches and weigh 118 lbs. When I was in my late teens I weighed 100lbs. not by choice or trying. I ate a lot - 3 meals plus snacks in between....I just had a fast metabolism.

I even wished I could gain weight then and used to get called Lynn the pin. Occasionally I would feel weak and I still can't miss a meal. If you lost weight and don't know why, I suggest you get a thorough blood testing done, especially your thyroid and iron levels. Make sure you eat 3 healthy meals plus good snacks in between meals. Now I'm very happy with my weight and don't have to try so hard to keep the weight on - think my metabolism is slowing down. From your picture it's looks like you have a similar bone and body structure as me. It's all in how you feel - if you're eating healthy but slightly underweight then you're fine.
