I see a lot of great advice on this board (I'm a semi-regular lurker, and very rare contributor), and have a few questions that I'm hoping some of you can help answer for me. I'm a fairly competitive runner, but I struggle, and always have, with my weight. A large part of this for me is my diet--while I eat really healthy and normal portion sizes during the week, I do eat things I should avoid on weekends (like chips and salsa, nachos, pizza, beer). Realistically, I have 12 pounds to lose to be where I really want to be. I have just started using the myfitnesspal app that I've seen recommended on here, so I hope that will help me really see what I'm putting in my body.
My fitness level is pretty good. To give an idea, I'm currently doing weekend long runs at about 7:30/mi pace (at 11 miles right now), and an interval workout on the track at 10k race pace (6:46/mi). The other days, I do easy runs around 5-6 miles (2 days), and I try to get in a short half-marathon race pace tempo run. Then, if possible, 1 day of cross training. Realistically, I get in 5 days of running and 1 cross training day (spinning or stair climber) on a good week, and 4 days of running and 1 cross training day on a not so good week. I don't do weights regularly, but do pushups and situps (I used to do a lot of weights--never saw a significant difference since I'm naturally pretty muscular).
So, what gives? If I'm tracking my calorie intake (myfitnesspal has me at 1200 per day), how much extra should I be eating to balance out the running? My body has always been very "efficient" in that I don't seem to lose much weight when training, but I hope that intervals/speed work will be a kick to my metabolism (I don't think I lost a single pound when training for the Boston Marathon last year-but I wasn't doing any speedwork either).
Any other tips to help me lose these 12 pounds? I know much of it will come down to what I eat--so I'm cutting out the beer, limiting (but not eliminating--that's not realistic) the weekened junk food, and not nibbling at work when there's candy/treats out. Thanks for bearing with the long post--and I greatly appreciate any advice and tips!
