Its more than just calories. What your body does to those calories matter too. Your body's chemistries matter.
You're absolutely right about exercising helping lose weight. An hour on a bike is 500-600 calories. A lb of fat is ~6000-8000 calories.
as a single example, I lost 35 lbs (16 kg) eating 4000-4500 calories a day (no carbs). I exercised 1 day a week playing ultimate frisbee in a local rec league.
- IncRnd 5y ago> A lb of fat is ~6000-8000 calories. A lb of fat is always 3,500 calories. Edit: Thanks to abfan1127 for pointing out my age. 4,100 it is!

- IncRnd 5y agoGreat point! One lb on Earth is .17 lbs on the Moon, which leads to 5.9 * 4,100 = 24,118 calories per lb of fat on the Moon's surface.

However, body fat is not just pure fat. Body fat consists of fat cells, called adipocytes, which also contain some fluids and proteins in addition to fat. Therefore, the calorie content of body fat is going to be a bit less than the calorie content of pure fat."
