No, it's not a dumb questions, but you can't argue the laws of thermodynamics.

Can you lose weight on NROL4W? Yes, if you put yourself in a caloric deficit.

Is NROL4W a weight loss program? No, not really, at the calorie levels outlined in the book.

As others have said, it all boils down to how one's body reacts to intense training. If you eat at a deficit and can't handle the workouts, then you are going to eat more or overeat. OR, if the workouts wipe you out so much that you just stop moving more in general in your everyday life, then you are losing that calorie burn, as well. It's a pretty individual thing, and only you can know what you and your body are capable of doing.

But, it truly does boil down to calories in/calories out when it all comes out in the wash.
