I dont think F1 guys are too concerned on low carb diets as they expend so much energy, but really focus on clean eating with a good mix of carbs, protien and essential fats. I spoke in depth to a PR guy from Red Bull at Suzuka last year and I asked alot of questions about Mark Webber’s training, diet etc as it is of interest to me and he deals with Webber daily and had some great info.
Webber cycles alot, uses a row machine for low impact and high intensity (he is getting on a bit LOL), does his outdoor sports, like in the Mark Webber Challenge in Tasmainia more so in the off season of course, and runs ALOT. For example when in Spa he said Mark will sometime run to the circuit from the hotel (6km or so from memory- not far for him but a warm up really). Obvioulsy pre-season the build to the peak and during the season maintenance.
Carbs will help not only energy levels but concertration as well so I cant see too many drivers being too concerned over a pasta or two. I have heard some stay clear of red meat but not sure if for training or health reasons (thats ok, I will eat their share!!)
For anyone out there who watches the UFC the fighters have switched from a high protein, bodybuilding like diet, to more a medium protein with lots of fruit and veg diet. Dont quote me here but I think more feed the body with carbs after a workout to replace gylcogen levels rather than protein to repair and build muscle. Both important of course but an endurance athlete (F1 driver and fighter) need carbs more than protein for this reason.
I wished we had more info on this stuff. Is Button still on a low carb diet approach ??
