> You need 2400 calories a day to maintain weight No, his sources estimates 2400 calories a day. You're right to question if he's consumed more, but taking his claims at face value, they match my own experience and many, many anecdotes I've seen over the year to indicate that advice of maintenance levels around that range are way too high for most people. > and were (off the cuff) burning close to 1000 a day from run…
I don't disagree with you, and I agree the numbers are slightly off (more like 2200 per day required and 800 per day burned, according to a number of calculators.) But even still, at 220 lbs, your estimate of 1500 calories a day should not cause weight gain.
And did, for that matter until I'd adjusted my intake further down. To notice much in terms of a loss I had to go below about 1600kcal before factoring in the exercise. I believe my maintenance level at the time was ~1800kcal.
If you're largely sedentary outside of your exercise, you can end up burning exceedingly little.
