I think that he's put a bit of weight back on, but I think he looks better than when he was very slim. I also enjoy his programmes, especially QI, and will watch his new show on Sunday with interest - after deciding what I'm going to record, or watch on Iplayer etc as I'd like to watch at least 4 things on Sunday night at 9pm now!
i think he's wonderful, a true british national treasure and eccentric. i find intelligence very attractive, and whilst there's no way i find him attractive in a fanciable way, i would love to meet and spend some time with him. he's definately one of my fantasy dinner party guests. loved his first autobiography but found the second a bit boring.
I think the diet he went on originally was quite a drastic one, a bit like a crash diet, inevitably he is bound to gain the weight back once he eats normally
If by 'normally' you mean how he ate before the diet then yes he will. So many people think once they have reached their target weight they can start to eat 'normally' again which was what made them overweight in the first place.
