I’m anemic too. Was 8.9 My doc had put me Sundown Iron Complex. While Keto, I was taking roughly 4 pills / day. After switching to mostly carnivore for about 6 mos, I am down to 1 pill about 4-5 times a week. It takes time. But, as my doc has told me over and over, you will absorb more iron -faster- from eating hamburger patty than eating spinach (or some other iron-containing veg.)
I had to eliminate the nuts, and veggies for the most part. The only veg I can really enjoy- very rarely- are broccoli, cauliflower and a little cabbage.
Making sure you are taking in enough fat from the beef is crucial to feeling full longer, and becoming fat adapted. I incorporate intermittent and extended fasting as part of my own routine, and do just fine. Yes, I do have to take one iron complex each day when I fast, but, that is not a game changer. I lose weight, and feel fantastic.
I eat mostly grass fed beef, then eggs, chicken & turkey. On occasion, some salmon or tuna. I do throw in a bit of dairy here and there. Just cheese, sour cream or HwC. Not a lot.
Again, it takes time. But the iron complex works so much better than anything I’ve ever tried. It changed my life. HTH
