In my case it's learned. I used to really look forward to breakfast, the thought distracted me. Then I got a medication I need to take first thing in the morning, and 30-60 minutes before my first meal. Since I kinda like being alive, I learned. I think it boils down to motivation: if you do this for yourself to find out if it's better for you, or if you already know it's better for you, it will work. If you do this just because some guy on the internet said it works for them, don't bother.
