High metabolism. This conceals the signs of obesity that are usually caused by your unhealthy diet. You should probably watch out for less obvious signs, like cholesterol, sugar levels and blood pressure.

I have a very high metabolism, and I'm short as well. I don't eat healthy, but I work out. But I also do drugs.

I'm underweight.. In my family, I eat the most.

Weird, right?
