Should we ditch the idea of three meals a day?

That would make sense to me if we didn't live in a world of food engineered to be addictive (talking about prepared food here)

I think now more than ever it's important to be strict about food rules (meal times, what kind of meals, etc.)

There is also a lot of culture involved in this. In my home country meal times and meal culture is sacred. You always eat at the same time and you sit down away from your desk to eat (alone or with people). Here in the US people like to eat at their desk or while in a meeting. I also have tons of meetings scheduled during normal lunch times, while back in the EU that would have only happened if there was some kind of emergency.

Overall I think the EU relationship with food is healthier
