It's not so much the meat, it could be the high amount of protein in your system with the absence of sugar and starch.
I developed hypoglycemia (low blood sugar) after eating ANYTHING a week after a went very low carb. I wasn't even a diabetic and very healthy. I never suffered such an episode, and they continued until I upped carbs to 100-150g and added starch and fruit.
What else are you eating? Beware of low carb. I know you're lean and young, so am I. I had no reason to restrict carbohydrates so severely. Carbohydrate restriction for healthy and developing individuals can be dangerous. Eat more CARBS.
I'm just assuming your carbohydrate intake is low. Don't just eat meat, eat vegetables or some potatoes with it. Eat some fruits after a meal, don't resort to dark chocolate and sugar. It could be iron but it doesn't sound like you had this issue before. Don't jeopardise your health and forget the idea that fat can efficiently replace carbohydrates as a reliable, healthy and stable fuel source. Don't get sucked into the low carbohydrate dogma.
If you want help you can always message me. Read the book. I can tell you some scary experiences about when I went low carb as a healthy, young and lean male and I did it right but it never worked out. x1 your lean body mass weight in lbs to determine an appropriate protein intake. For example, I'm 130 lbs and consume about 100-120g protein a day.
You are young. Stop over thinking it. Going by your previous posts, you don't even gain weight on a typical diet and your health is fine. Why are you doing Primal? Don't compromise your health.
