Haven't bothered reading whatever the poster after you is referring to, but Macca is no where near 175 in that picture. It seems he is only 5'11" and most places have him at 150lbs, which is probably closer to true weight. I am 6'1"+ and weigh ~165 and look like Arnie compared to Macca. BTW, it probably depends on the athletes...some are lucky and can eat anything and not put on weight (I am not a pro but fall into that category and have ~5% body fat and don't train too much (a lot less than 10 hours/week)....the more I work out the heavier I get!!).
Edit: and I eat absolute crap...no vegetables unless someone cooks for me or I am eating out, 2-3 cans of coke at work and a 2 litre bottle in the evening (although this maybe Mountain Dew instead). My customary Rocky Road bar in the morning from work cafe plus 2 cookies. The afternoon is something from the vending machine (lately it's been Doritos). In the evening a bag of Haribo (or Pringles if feel like something more savoury), a Skor bar (addictive little bastards....they need to crush those bars up and put them in a big bag, reckon they would sell like hot cakes) and something else (often a chunky Kit Kat at mo). This is around the normal meals of breakfast (this varies a lot from Dunkin stuff (#1 (2 donuts and coffee) or one of their sandwiches) to waffles or eggs), lunch (normally a turkey or chicken sandwich with honey mustard, swiss cheese and tomatoes), and dinner (order in a lot as Manhattan has everything at the press of a few buttons (Delivery.com)...sushi is a favorite as is Thai, Chinese and Indian). So basically, rubbish.
