how to know how much fat we have?

Answer 1

Just take a good long look in the mirror and if you don't like what you see, then you are fat. I took a look at myself the other day and almost died because I didn't realize how much weight I had put on. It's back to the gym tomorrow because I look like a fat slob.

Answer 2

I think if you pinch your stomach with your fingers and count the inches, then you'll know how much fat you have.
