from Better Is Better: Fast-5 Fat Loss - Part 2 Of The Bert Herring Interview
Adam: That makes sense. I wanted to ask you about hunger. I think any one that's tried fasting, will probably be a little bit more familiar with the different types of hunger that exist. You tend to experiment with it a little bit when you're fasting. You discussed certain categories in your book; can you just talk about that a little bit?
Bert: Yes, I refer to two types. One that's called somatic hunger. "Somatic" just means "of the body". The other is limbic hunger. Limbic hunger refers to the limbic system of the brain which is where your instinctive behaviors are.
The reason I make that separation is that there's hunger behavior when a person is driven to eat despite whatever they might feel in the rest of the body. The somatic hunger refers to the sensation of discomfort in the belly.
One of the things I became aware of, that's why I did my study on this, is that many people go through the behavior of eating and are driven to eat, and I had seen myself doing this, even if they had a conscious recognition that they were not particularly hungry.
And certainly a conscious recognition that the fat storage was certainly ample on fuel. So they knew they didn't need the food, they weren't necessarily feeling hunger in their belly, but it was still a compulsion to eat. So that's what I call limbic hunger. The somatic hunger is the crampy, uncomfortable feeling in the belly.
Adam: Interesting. It's driven a lot I would imagine by emotions, boredom and social aspects play a big role in driving those hungers. I liked in the book how you said that just shutting it off completely, just throwing the switch, helps you overcome that urge to eat.
Instead of saying, "Well I can just have a little bit of this and a little bit of that", which turns into a lot of something you didn't mean to eat in the first place.
Bert: That's one of the keys of any fasting regimen success, I believe. It's a lot easier to just not eat than to eat a little bit, because of the instinctive response that we have apparently acquired. When our bodies realize that food is available, it is a drive to eat more than what we need of it, so that we have some stored for later.
Adam: Which was probably very useful a couple of hundred thousand years ago.
Bert: Absolutely, because all we had for a refrigerator was what we could store in our bodies
