It was a major epiphany for me when I first went lowcarb and found for the first time in my life that I was not hungry all the time anymore. It truly was an eye opener that my desire to eat or not eat was mostly biological. Seems obvious now, but for all my life, everyone always said people are fat because they have lack of self control or low self esteem or whatever. And I'm not saying those are never part of it, but I never realized how biological it truly is until I experienced for the first time how trim people must always feel, ie satiated with normal amounts of food intake for long periods of time.

As for the case of eating very low amounts of calories, I am going to go on my instinct and suggest maybe a light snack in the morning just to keep things in balance. But personally I would not worry too much about it yet as long as you are not getting too skinny and as long as your energy level is still good, you don't feel rundown etc.

I would also add that you should probably be eating very high density nutritious food if you are not eating much. And you may want to consider nutritional supplements for any nutrients you are not getting. Go to fitday.com and see if you are lacking anything on current intake of food. You may already have plenty of calories stored on your body, but that may not be true of vitamins and minerals. YOu are probably still a big person but now intaking a small amount of food. Your body can replace the missing calories using stored fat but it may not be able to do the same with vitamins and minerals. If you are eating very little, it would be easy to be deficient in some nutrients. You may not need to eat more but you probably should make sure you are eating smart with very nutritious food and maybe even some supplements if you are deficient. THe more you weigh, the greater your need for nutrition. Normally, I'd say shy away from supps but I think it's hard to eat enough nutrientss when your body is still big and your food intake is small. However, if you are very crafty in your food selection, you could probably do it that way as well.

Almost everyone starting paleo experiences the no hunger "syndrome". Make your body into a fat burning machine by eating around 75% fat, 20%, 5% carbs and you will do just fine. Trust your instincts. If anything says wheat products, sugar products, corn products avoid. Small cheats can sabatoge your weight loss process. Determination and willpower.

But be sure you drink enough water. New paleo people tend to be satiated from the food they eat, that they do not get the thirsty pangs.
Some sites say to multiply your weight by .5 and that is the amount of water to drink on a daily basis. Best to break that up into amount per hour. I tend to add 25% to my number. It flushes out any toxins I am ingesting or come in contact with and it is terrific for BMs.

Id only be concerned with your body sending the wrong signals, if you were also suffering from extremely low energy, thats when id be concerned about inadequate nutrition.

When your activity levels go up, youll find your hunger will follow.

Id really fix your sleep if you can, I cant stress enough how important it is for EVERYTHING. Id be FAR more concerned with poor sleep than being hungry.

If you can, play around with shifting your meals a little earlier, so you can go to bed without being in the middle of digesting your meals.

Make sure youre turning off electronics/lights at least an hour before you want to crash.

Im going to break from my rule and recommend a supplement too. Melatonin is great for getting back on a sleeping schedule. get a 3mg timed release one. timed release is important if you dont want to wake up in the middle of the night. Take it an hour before planned bedtime, when youre turning off all those lights/electronics. in 1 week, switch to every other day, after 2 weeks just stop taking it. You'll fall asleep faster, more lucid dreaming, the whole 9. It definitely helped me for a short term fix to put my clock back in line.

I don't have reliable hunger signals, due to past disordered eating, but I love to count, so I just track my numbers and make sure I'm where I know I need to be to maintain my weight.

I've don't think there is anything wrong with only eating once per day if you are eating enough. I found if I under ate it actually slowed my weight loss down. So you may want to count for just a day or two to see where you are at.

It took me 6 years to lose 111lbs. I think taking it slowly and learning about nutrition as I went is what will help me to keep the weight off. My body and mind adjusted along with my weight.

I personally don't agree with the exclusion of starches, but if you feel fine and are consuming green leafies to supplement the fat and meat, it should be sufficiently healthy. You are carrying around plenty of calories that your body will toss into the furnace as you go, so I would wager that your hunger would gradually increase as your adiposity decreases.

When I first went paleo I definitely had diminished hunger signals. I was concerned at first, too, but most things I saw online about it (on the paleo blogs) framed it in a positive way. I think if you feel fine and you have weight to lose, then you're doing fine. Eat when you're hungry or when you think you need to.

I'll leave it to someone else to share links and opinions from varied sources, but I just wanted to state my personal case. When I went paleo, I dropped about 20 pounds in two months, almost all of it fat. I was pretty much not-hungry the entire time. Now that I'm still strict but 20 pounds lighter, I AM pretty hungry on a predictable schedule, more like I was pre-paleo (but without the nasty headaches and inability to function -- real hunger, not carby hunger). Also, things may fluctuate based on hormone levels, mood, etc. You never know. As long as your gut isn't telling you to eat Oreos, I'd trust it! :)

I went largely Paleo last year and didn't even know it (grin). What happened to me was that I had terrific nonstop cravings for high added sugar food-like products for about a month. I thought I was hungry all the time. But once I got through that, my hunger faded away, and my appetite regulated, just like others are describing. The key for me was to pay attention to my appetite, make sure I was getting the biggest nutrition and taste bang for my buck, and then I tried not to worry about controlling it or it controlling me.

It is such a welcome relief to have a friendly, non-anxiety producing relationship with food and eating. I don't keep 100% Paleo (I eat a fair amount of nuts and fermented dairy, plus the rare hard cider and dark chocolate), but mostly I eat the freshest whole foods available. Within my limited starving artist budget, if I can't afford local, in-season, I go for variety and high quality.

What I'm interested in learning is how long it takes the body (within a guestimate range) to re-regulate things such as n6:3 ratios, for adipocytes to release stored toxins and reregulate, for organs (skin included) to recover and to what extent this happens when on a Paleo diet, and what kinds of compensatory mechanisms we have to tolerate variations in diet (the multicultural aspects of eating are fascinating). There's so much to learn and so much still to discover.

Glad you are on your way. Enjoy the journey.

Sometimes your body speaks but your brain does not want to translate. I assume that eating those oreos occurred somewhat outside of your control. It was that way for me, anyway.

You have to trust yourself and allow your body to tell you what it means. In this case, you might be flying high and proud of not having to eat much anymore. (I fell into the same trap when I started paleo). It was totally psychological for me, and I finally have some sense of control over my food habits.

The truth will set you free... :D
