Yes, the number depends heavily on many factors. I'm not too tall (5'11) and fairly slim, and if I hit 2,000 regularly I'd be getting fat even working out 3 times a week (1-1.5 hours). Maybe in the summer, when I go biking almost every day on top of that. It's cutting it really close for me, and a mystery meal for lunch once or twice a week can push me way over. Your average woman eating 2,000 is gonna blow up quickly, even if she's running a dog walking business.
