Surgery is a quick way to lose weight, and after that, you don't change the eating, working lifestyle, it's also gain quickly

I think the most important is changing lifestyle first, move more, eat less junk food. I haven't enough time for exercise, so I put water far from me, when I am thirsty, I have to move my obese body to go there. Instead of sitting and eating snack while watching TV, I stand or go around.
It's funny about my new lifestyle, my sister laughed at me on first days, but now, she just smiles and says "keep on!, bro".
I usually say that my reason to lose weight is to be able to look straight down and see my toes instead of bending over to see them!
Lots lucks to you!
