I'm obese.
I see. Why are you overweight?
Because I'm too lazy to exercise.
If you are obese, then you need to start working out and talking with a doctor about a weight loss plan. The doctor will be able to help you get healthy so you can live longer. If you don't start working out and losing the weight, you could die at a very young age.
No need to make such a big deal over it, I'm just too fat.
It's your body and your choice in the end, so as long as you're happy you don't need to lose the weight yet. I'm just trying to say that there are health risks, so wouldn't you want to see a doctor and learn to live longer?
