Last winter I'd ballooned out to around 113kg (I was pretty strong, I ground out a 205kg squat, but I was way too heavy ...)

Then I read Taube's Good Calories Bad Calories and Joe Friel's paleo food book.  I'd been eating like an enduro but training sprint, and the animals are different. Enduros need junk carbs because they're (if they're training enough!) burning them off and are chronically glycogen depleted.  Sprinters aren't (quality, not quantity, we have to train fresh), and therefore don't need anything like as much junk carbs as enduros.  The food you eat as a sprinter must be different or you get fat, very fat ... As I found out through personal experience!

So, out goes pasta, potatoes, grains (bread) and rice.  In goes more eggs, meat and green veggies.  I'm aiming for ~2g/kg of protein, so for me that's around 210 or so grams of protein a day (4 chicken forequarters, a load of bacon and eggs, lots of steak, chops etc).

It's worked.  I'm now ~100kg and still reasonably strong.  Due to an ongoing shoulder injury I can't squat but I can deadlift and front squat and my numbers for that aren't down too much and I'm down about 50 watts on the ergo but 13kg lighter.  This should translate into better acceleration, and I'll get that 50 watts back once my shoulder's working properly.
