impressed: My brother used to be really overweight and one day he just didn't want to be anymore. He started dieting hard and even though he isn't done, he looks so much better and I'm really proud of him.

My brother used to be so much more overweight than he is now, since he has been putting a lot of effort into losing weight recently.
