Welcome to the joys of intermittent fasting.

Eating only when hungry is such a novel idea in our modern snack food world, your friends might think you are nuts, but you are now in touch with your real hunger, congrats.

I used to be hungry every 2-3 hrs on carb diet. I'd wake up ravenous. Now I eat lamb and beef mostly, with some greens a few days a week. For a while I ate macadamia and avocado, but I just feel the best on animal fuel. I wake up ready and able to eat, but I could skip breakfast if I want. What I do instead is go ahead an have a big breakfast to last me throughout the day, workouts included, and then have a big dinner, 3 days per week when I'm not working. On work days I eat a lunch at 3pm to get me through the mental stress at work. Running on fat feels like diesel fuel!

What you're describing is what happened to me--and it's why I find intermittent fasting so easy.

I'm a night person. I go to bed at ~5:00 AM and wake up at noon. I'm not hungry at all upon waking; if anything, the thought of food is repulsive. So I have my coffee, and that's it.

My IF eating window is between 6:00 PM and midnight, which for a day person on a normal schedule would be between lunchtime and early evening. So basically I eat a huge lunch, then maybe a snack later on, and that's it. It's a lot less food than I used to eat, but since it's much higher quality food it's enough to satisfy and sustain me.

I used to eat big, late dinners, then go to bed with a full stomach not long after--and I'd wake up ravenously hungry. But if I go to bed on an empty stomach, I have no hunger at all in the mornings. Odd, that.

Even if I do wake up hungry, it subsides quickly.

I'm a bit more conditioned towards breakfast - family tradition had always been to have a very big breakfast on weekends, and so for the first 3 days of the week after I wake up expecting to smash bacon and eggs first thing (as that's exactly what I did on Saturday and Sunday).

In a perfect world, I'd eat a big meal between noon and 4pm, and call it a day. Every time that I've done that, my hunger seems mitigated mostly throughout the day and I get a huge IF window.

I'm usually hungry in the mornings, but then probably not until about 8pm at night after that.

Both my husband and I have noticed a huge difference in our hunger levels since eating Paleo, to the point that we were quite worried about it.

Last weekend for example, we went wild camping in the mountains, walking 10 miles each day. Apart from a few handfuls of nuts and raisins and some jerky, we didn't eat anything until we got home on the Sunday night. Even when we stopped for the night after 4 hours tough walking, we just weren't hungry and could have kept going of the light had been better. Usually we would have had to stop loads of times to re-fuel, but this time, the mountains felt easy :)

When I started I use to always be hungry, even after eating. I use to have wild sugar swings and nearly always fainting and seeing black spots (I soon discovered it was salt issues not sugar, but always popping candy).

I never use to eat breakfast, I'd wait for lunch....but now I force myself to do breakfast and eat a late lunch/dinner.....I'm never hungry, I've actually gone 3 days (not on purpose but stuck flying international with delays/cancellations etc.) without eating more than water, banana, few nuts, and I was not at all hungry and content....its possible to do if you are in balance.

I find If I use honey at any meal I'm hungry sooner, so I guess its the sugar factor for me, not the carbs that makes me crave/hungry.

I make sure I start cooking my lunch/dinner before I'm hungry, make myself eat it, otherwise I could go looking for food and not have the patience to wait for it to be ready.
