I am eating a VLC paleo diet currently, but I am still experiencing strange fluctuations in hunger.
The best way I can describe it is that I'll get hungry all of a sudden but then if I wait it out for ten or fifteen minutes, it goes away completely. It's not the kind of hunger that slowly builds up until I feel the need to eat. It is very uneven and is making me question whether I can trust my body's hunger signals.
Could it be that this a sign that something is off with my insulin or leptin? I was overweight for most of my life and am trying to lose the last 10/20 lbs. I'm just looking to understand what is going on in my body physiologically when this happens. If anyone has any ideas, I'd love to hear them!

i have come to accept that this is a fact of my life. i can't explain it; especially when it happens 10 minutes after a 500 calorie meal. but like yourself; if i ignore it it goes away.

For background, my regular diet is rather low in carbohydrate (the only carbs I take in other than that found in non-starchy veggies and nuts is from the occasional sweet potato, squash, white rice, or other starch that I throw in every few days).
To your question, I have experienced "flash hunger" and am especially aware of it on days that I am fasting.
I've begun to incorporate a weekly fast of 24-36 hrs and, for 90% of the time, I actually don't feel any hunger whatsoever, but there are particular moments when my body seems to be yelling "FEED ME!" As you said, however, these pass and I go back to feeling fine.
One thing that I have noticed is that food advertisements, or, especially, if my wife is sitting on the couch eating right next to me (to the point where I can smell food), seem to stimulate the feeling.
It very likely has to do with blood glucose and related hormonal systems (insulin, leptin, etc.) My own personal theory is that something stimulates the release of insulin (image of food, smell of food, etc.) which causes blood sugar to drop and thus the hunger response. If, no exogenous source of glucose is present, the body eventually switches to some endogenous form of glucose production/fatty acid liberation and the feeling of hunger dissipates.
