To those who count calories to keep a certian wieght, how did you start and where do I look for the most accurate info? Ive calculated my BMR to be 1900 calories (without cycling) but this is where I have found some discrepencies. On some websites it lists biking at 16-19 miles an hour burning anywhere from 500-1000 calories per hour. What have you guys found to be the most accurate?

I need to lose some wieght (prolly 10-15 pounds). I am 6'2 and about 180, maybe a little less depending on the day. I am NOT fat by anymeans but have some stomach to lose (beer) and I feel being that much lighter will make me faster on the bike, plus I could get my 6pack back!

ANY other help is much appreciated. If you guys have a website you like or a routine that works let me know. A big concern of mine is not eating enough, I get really bad headaches and feel like crap if I go a work shift without eating because of forgetting my debit card. Should I plan on eating the majority of my calories before riding for the day and eating small after???? Thanks in advance.
