I recently started the paleodiet earlier in the week, on Monday, and the first couple days went great: ate lots of fruit, concentrated on protein (not a problem as I'm a former bodybuilder/powerlifter) and ate more vegetables than I normally do. On tuesday, no less than 36 hours into eating this way, my actual resting blood pressure had gone from a consistent 136/85 to 125/75, plus my thinking was so clear it was kind of unreal to me (I also have adhd which I take meds for 2-3 days a week, depending on my schedule with school). On Monday and Tuesday I i felt great, although a little hungry before bed on Tuesday. Wednesday morning (after sleeping only 5 hours) I got up had a banana only then an hour later I had the most intense low-blood sugar fit I've ever had in my entire life! I nearly blacked out a couple different times. I decided I needed some carbs, and spent the morning putting a fair amount of neo-carbs down until I felt better. By mid afternoon, I was feeling stable again.

As far as what I ate those previous two days, you'd have thought that was fruit and protein were going out of fashion the way I was eating it, I was actually concerned with overdoing it.

So what gives? Why did I have the low-blood sugar fit on the 3rd day? Thoughts? Theories? Questions?

Ok, but what forms of fat are best? Is it just eating fattier cuts of meat or am I adding more oils like olive or macadamia?

Too many sugary carbs is probably the reason for your hypoglycemic episode.  Believe it or not, fruits, especially bananas, are very sugary.  It caused a blood glucose spike (sugar high) followed by the release of insulin, which cleared a lot of the glucose out of your bloodstream, and overshot its mark, causing your "sugar crash", low blood sugar. 

I heartily agree with  goodsamaritan and LoneWolf.  Cut down on the amount of fruits.  Replace the fruits with more fats, protein, and vegetables.  Fruits have been selectively bred for centuries to be bigger, juicier, and more sugary than their paleolithic predecessors.   Best to keep the fruits down to an occasional treat, not an everyday part of the diet. 

You'll hear the mantra repeated often on this forum - Protein and Fats.  Protein and Fats.  And add some veggies for variety, and occasional fruits, if you want.  I've found that after eating mostly meats & fats for a few days, a piece of fruit like an apple tastes way too sweet- like I have a mouthful of sugar.   

The key concept is high fat low carb diet.

I feel for you krypto, I used to suffer from episodes like hypoglycemia when I eat too much carbs, my hands shake from the crash after shooting up with carbs I have to shoot up with carbs again.  I used to think it was normal during my SAD days and even up to my raw vegan and raw fruitarian days.

I only learned about this when I transitioned to a high fat low carb diet by start of 2009.

Try to make that transition, you will find it such a relief.

Thanks for the great tips everyone, they have given me a lot to consider. I am going to keep the fruit on in the mean time but will make sure to add more fat.

I did the original zone diet back in 98 and had great results by keeping the fat and protien mixed with carbs. If anyone remembers Gene Daoust, he put out a book called 40/30/30 Fat Burning Nutrition and had a fat-flush program which is now just basically what you would call the paleo/zone type combination. Anyone have success with that?

This EXACT same thing happened to my brother when he was staying with me. Haha. He usually eats more carbs than I do and I only keep meat in my apartment. So, after two days (just like you) he awoke the third morning absolutely ravenous and hypoglycemic. He ate some eggs and went back to bed. A few hours later he couldn't move and was shaking and felt like he was getting really sick. We got him some frozen berries and he was back to normal within 10 minutes. So... the eggs cooked in lard did NOT work to fix the hypoglycemia.

Your body takes TIME to adjust to creating glucose from protein if you cut the carbs real quick. You can't just eat more meat and expect it to go away becasue you will not make much glucose from it yet. I say, keep some fruit around and if you feel sick have a little bit (like a few berries. Do NOT eat a whole banana or even a whole apple) and once you are a fat burner instead of a sugar burner, you won't ever need the fruit because your blood sugar will be pretty solid

marika,
Yes it totally depends. I transitioned to a carnivorous diet after binging on carbs and had no hypoglycemia whatsoever. I wish I could say the same for my brother.
