That probably stacks up there in the bro science hall of fame for being wrong while sounding plausible. What's next, recommending an all meat diet because we were carnivores 10,000 years ago?
Look it up if you don't believe me.
Sleeping burns 40-80 calories per hour, walking 200-350.
You're not gonna burn off any calories by walking.

We must have different definitions of "roughly", that's an order of magnitude difference!
> You're not gonna burn off any calories by walking.
That's a very different claim (but still not true).
To be clear: walking is great exercise. No, you're not going to walk off a 10,000 calorie/day diet with it; you need to not eat that much. Nor are you going to look like you spend 3 hrs/day doing crossfit just by walking. But 10,000 steps per day is miles better than 500.
You burn roughly as many calories walking as you do sleeping.
