So who does it and how many do you allow yourself per day?

I track my eating on a regular basis. Fat is generally limited to 25% or so, but not necessarily each day. Over time though, I tend to hit 25% Fat, 25% Protein and abut 50% Carbs. I work hard to make sure that most of the fat is other than saturated and that the carbs are complex and include fiber. I don't obsess over it. I just track it.

I've been tracking (most days) wha I eat on Training Peaks, and it almost always comes out to be a 60-20-20 ratio, so for example today I ate about 4100 calories with about 89g of fat. I prefer to keep it down to around 60g, but even eating relatively lean foods it adds up fast. About 8g was from avocado, and about 30g was from various protein/energy bars, and most was low on the saturated fat. That's the biggest thing I watch out for is the saturated fat, of course after trans fat. I won't eat anything that has more than 0g trans fat, and avoid most things that have hydrogenated oils listed.

I don't bother to track what I eat on long ride days; Sunday I rode 140 miles and according to my heart rate monitor burned approximately 6000 calories. I know I ate a lot of carbs, a fair amount of protein, and relatively very little fat.

I don't track what I eat, just how many calories. Fat is very dense calorie-wise, so I tend to avoid it, but I have no ratios.

I just do 1500 good calories per day. Eat whatever but not Mcdonalds. I had a buddy doing 1500 a day but he ate once a day at mcdonalds. Thats not was I meant lol. Eat some good calories every day, keep it around 1500, I lost 40 pounds with it.
