I was never really that fat (just size 35-36 then); more on a bit of a chubby one. But I have been more confident now having come 4 sizes down. Possibly even 5 since I can get into size 30 jeans even. So that's a big thing. Of course maintaining it is the other half of the battle.
Size 35-36 is fat if your height is only 5ft. Hehe
For the topic, looks aside, I believe one is more at risk of getting sick when he/she is overweight. Plus you would also look better if your weight is just proportionate to your height. I didn't mean to offend those who are overweight though. Anyway, it's really more of a health issue to me.
