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 running and other activity.
I very much doubt that. My own off the cuff estimate is ~500 calories a day for that activity.
> There's no way you'd gain weight at 220 lbs effectively consuming 1000 calories a day. I've lost weight eating more than that at 180 lbs body weight.
More like 1500 by my account, possibly more depending on the intensity of his exercise. And if you assume lack of substantial muscle-weight in that, it matches pretty well with my own experience from before I started lifting weights - I had diets where I had to drop to around 1200/day before it made a noticeable difference.
Once I started adding muscle, I could get away with more, but not a lot more.
I don't doubt your numbers, but to me they'r why we shouldn't listen to estimates, but measure, as activity level (all day long, not just during exercise) and body composition makes the error margin on estimates of metabolic rate crazily high.
