Let's suppose you're coming from a lower meal frequency to a higher meal frequency. The reason is, you want to bulk and gain weight.
So you decide to have something like 4-5 meals a day instead of your usual 2-3. Suppose you set it at:
8AM - breakfast
1PM - lunch
6PM - after noon meal
9PM - dinner
[Just an example of a 4 meal, your preference may vary.]
Suppose you're also on high carb paleo, if that makes any impact to your answer here.
If you wanted to go back to your usual 2-3 meals a day, after staying on a 4-5 meals a day for a couple of months, how hard would it be to overcome ghrelin and your body habituation pattern, and how would you do it?
P.S.: What do you think about... gluten-free oats? Are cooked any better than eating it raw? Or the fact that it's still a cereal is no-go in your book?
