Anecdote: I've been running 40-50 miles a week, tried various diets, but I still was chunky. Last two months I run 5-10 miles a week, eat sugars and crap but I record everything and eat around 1200-1500 calories a day. I've lost a crapload of weight.
Yeah, I'm also a 6'3'' and I was 220 in March so I'm probably grossly undereating but after a week of hunger and headrushes you get used to burning fat (I also drink coffee) for energy and feel great while losing weight.
Well done! At 6'6", I've lost 25 lbs in 3 months (from 252 to 227) strictly from keeping my calories between 1200 and 1700 per day. This includes a high intake of alcohol and otherwise I eat the same crap I always have - just far less of it. Although, now that I'm beginning to plateau, I guess I'll have to start going outside to play a little more often to get rid of the next 20 lbs.
So if you want to have an enormous, 1500 calorie meal at a casual dining restaurant, go for it, just keep it light for the rest of the day.
