I've been doing this Paleo thing for a few months and I've found that I'm never hungry, but I get light-headed/headaches very easily. When I noticed this trend, I started counting what I was consuming and noticed I had to try hard just to consume around 800 calories a day. But since I've started the Paleo diet, I've never felt hungry.

What should I do?

how much are you sleeping? a deep ketosis with calorie restriction isn't so much of a problem if you're sleeping 10-12 hours a day. it's approaching winter in the northern hemisphere so that could be normal. if that won't work for you, then yes, you'll need more carbohydrates to pull you out of hibernation mode. – APC Nov 26 2011 at 4:00

800 calories? Are you crazy?! – Adulescens Appetens Nov 26 2011 at 4:17

Double those calories at least, Young. You need them, for real! – January Nov 26 2011 at 23:50
I realize how little 800 calories is, I'm just saying it was hard to eat more because I wasn't hungry. – youngwildhealthy Nov 29 2011 at 2:24

Extreme calorie restriction can be addictive, even if it was completely accidental. The way your body responds when you don't eat enough may just feel really good, and so you start to severely dislike the idea of being full or having food in your belly or using any extra energy to digest, which can result in something that feels like not being hungry. Just like people who consistently overeat have a hard time understanding the difference between being hungry and just wanting something to munch on, people who consistently undereat (even if accidentally, like yourself) can suddenly have a hard time telling the starvation-induced-high from the feeling of not actually needing food.

So, I agree with everyone else about eating more. I don't know enough about to say it should be carbs or something else, but since you've already gotten to this point, I'd definitely say eat more calorie-dense foods that go down easily, because eating when you feel like you don't want to (for whatever reason) can be unpleasant and can reinforce the cycle. So eat nut butter, cheese, etc. Eat all the things that people trying to lose weight can't eat because they're just so delicious and calorie dense that people can ingest 1k calories of the stuff before they know it and it doesn't make them feel full. Same with yams, not just for the carbs, but again because they go down easily and don't tend to leave you feeling stuffed the way, say, a steak will.

Just like people who overeat need to heal their brains and satiety/hunger signals, people who consistently undereat for whatever reason need to do the same (and a few months is certainly enough time for this to happen).

Let us know how it goes!

You are likely in deep ketosis, which will suppress your appetite utterly. When I first went very low-carb and was in deep ketosis, I was accidentally only eating 900 calories because I was not at all hungry (or so I thought). Eventually I passed out on the sidewalk. Not good.

You MUST eat more...800 calories will NOT sustain you! And with only 800 calories, you're almost certainly not eating enough carbs to stay out of ketosis and thus avoid such intense appetite suppression. Your brain isn't getting the signal that you need to eat.

Checking with a doctor is not a bad idea, but in the meantime add some calories to your day even if you're not hungry. You need food but can't feel it. You're hungrier than you realize. Trust me!! And let us know how you do!

Also, several months of only 800 kcals is likely giving you some deficiencies, as Nance brought up. Over time you'll feel that more and more. Mange, mange! :) – January Nov 26 2011 at 3:26
Thanks so much. Do you have any reccomendations of foods that are high in calories? – youngwildhealthy Nov 26 2011 at 3:34
In your case with the appetite suppression, I would combat it straight away with sweet potatoes or yams with plenty of butter. That will lift your ketosis by providing carbs and let you feel natural hunger signals! – January Nov 26 2011 at 3:49
Thank you! !! – youngwildhealthy Nov 26 2011 at 3:52
YVW, youngwildhealthy! keep tracking your calories, too; that was excellent proactive-ness on your part. :) – January Nov 26 2011 at 3:55

I'm not a trained professional, but clearly something's not right.

It might help if you share your age, activity level and any general health history that's relevant? What foods comprise your 800 calories, which is of course extremely low?

Being light-headed can be benign, as in postural hypotension when you stand up (I had this when young and it's nothing to worry about.) Or, it could signal that you are malnourished or deficient in important nutrients.

Lack of appetite is worrisome only because you are eating so little and light-headed. Have you seen a doctor lately?

You are simply not eating enough protein and fat to maintain your blood sugar. Many of us use coconut oil, which has 117 cal per tablespoon. I have 8 to 10 tablespoons a day and I eat at least 60 grams of protein as animal fat a breakfast and the same at dinner. Only carbs I have are sweet potatoes and yams slathered in butter. Your lightheadedness is the result of not eating enough protein to convert to glucose to fuel your brain. I would bet that your blood glucose would be in the low 70s most of the time...not enough to fuel your brain. – Dextery Nov 26 2011 at 3:38

Dr Rosedale, in his last response to Paul Jaminet safe starches thesis still says there are no safe starches if one is looking for optimal health and longevity of life. drrosedale.com/blog/2011/11/22/… – Dextery Nov 26 2011 at 4:24

She's only 17 and still growing and developing; she can use some carbs. Not having carbs is suppressing her appetite too far and WILL create immediate and dangerous effects. She's already dizzy from not eating. She needs to have her appetite stimulated. Carbs will do it. Recommending against carbs in this case is absolutely unsafe. And I speak as a dedicated low-carber -- it's not always reasonable to avoid carbs. – January Nov 26 2011 at 6:11

An active teenager who is anorexic due to ketotic appetite suppression is in danger of all the effects of anorexia, Dex. It's not the lack of carbs per se; carbs are not necessary to sustain life. However, the lack of carbs in this situation is absolutely kicking off an anorexic response. THAT is what is dangerous. Telling someone at 17 to stay off sweet potatoes when they're nearly passing out from hunger is stupid. – January Nov 27 2011 at 1:14

My! A firestorm of opinions. Youngwildhealthy, I hope you've read all of the comments. The bottom line is, find some high energy (think nutrient-dense fats/proteins/carbs) and EAT. Worry about macronutrient ratios and ideal menus when your appetite wakes up and you're back to finding a good balance of overall nutrition. EAT-EAT-EAT! I want to hear good things from you! – Nance Nov 27 2011 at 1:45

Are you the only Paleo in your house? I am that way and it can make it hard to find the proper food when everything around the house is not Paleo. You need more variety in your diet. I have a similar issue. However I also eat eggs. Meat alone will not be enough. It takes awhile to find your sweet spot for eating. I also eat veggies and fruit and vanilla ice cream. I would also eat chocolate ice cream but I can't because of allergies. Potatoes would be a very helpful food. Every meal have at least two macros. Fat, protein and carbs. So if you are eating meat you have a veggie or butter or bacon. If you have eggs also have butter, veggies, bacon (even better have all three.)

Eat when you are not hungry. Your body can handle the extra food. The addage eat when you are hungry does not apply in this case. Do plan on eating at regular meals with larger portions due to more varied food.

It sounds like you're getting a serious dose of satiety hormones (leptin and/or PYY) from the protein (and fat?). Maybe try starting your meals with carbs, like fruit or root vegetables, before eating the meat, which causes the PYY & leptin release that kills your appetite.

That much athletic activity on so few calories is worrisome from numerous angles. You're young and you may be wild, but your practices are not healthy, or more aptly, not healthful. Google Karen Carpenter, for the fun of it. If what you read isn't fun, take that as a good sign.

You run everyday so you need more carbs. You don't need to be in ketosis. Eat up all the whole foods you want whilst keeping those processed carbs out.

If you continue running and eating only 800 calories daily you'll be stripping your muscle mass which you don't want.

Try eating more fat and less protein. The meats you eat all are high in protein and low in fat. You can overdo it with protein depending on your metabolism, and meats take longer than carbs to leave the stomach, thus leaving you fuller longer. Since you're very physically active and not eating nearly enough calories, my guess is the light-headedness is from hypoglycemia. If you eat enough protein and fat without any carbs most people can avoid this because the body starts gluconeogenesis to stabilize your blood sugar level. But you seem to have cut out both fat and most carbs, which will lower both your blood sugar levels and your metabolism. Do you eat fat with your meals? I'd recommend eating more fat and carbs in the form of starches like sweet potatoes or yams. Everyone is different in terms of macronutrient needs, what's important is that you cut out high sugar foods and drinks and other harmful substances like artificial sweeteners and caffeine. The way you can find out what works for you is to try different ratios of carbs and protein and observe if you have more energy or not. If you felt the need to binge eat that could indicate a nutrient deficiency, some degree of metabolic problems, bacterial dysbiosis, or too much stress in your life. But your goal should be to increase your calories and go from there.

Take a potassium supplement with each meal and chelated magnesium twice a day. I had the same problem, my Dr tried to put me on blood pressure medication but the warnings and side effects scared me so I started taking potassium and magnesium and the issues went away. I also stopped counting calories. I just make sure I get protein (2-3 oz), fat (a few nuts or tablespoon fat) and a huge serving of low carb veggies at each meal (and a cup of berries with breakfast). I eat about 4-5 times a day. Read The Protein Power Lifeplan by the Eades. Good luck!
