Maybe they weren't being totally serious? Either way, get on a healthy diet and start exercising. You'll thank yourself later in life when you're lean and healthy.

That's such a parental thing to say. My mom encouraged me to take diet pills when I was 12 and at a HEALTHY weight. I don't know why parents can be so judgmental about weight, my grandma is too. If I had kids, I would think they were beautiful no matter what, regardless of weight. And dear god, if they told me they were under a lot of stress I would help them immediately...I'm sorry your parents suck.
