Ok- so I just started primal 2 weeks ago. I have hypothyroidism (i'm on meds) and I'm (usually) very active. I took more of a cold-turkey approach and switched to primal all at once and lowered by carbs to about 150g (from probably 250ish, i'm a runner). I expected to go through a carb-flu type thing, which I did- I had some blood sugar crashes that gradually got better, but my hypothyroid symptoms got worse. I feel freezing all of the time and my body temp is not breaking 98. Also, my muscles are very fatigued and not recovering well. I'm confused because I'm not even that low-carb! I really want to be primal but I don't want to just further ruin my thyroid.
Has anyone ever experienced this? Maybe I should add carbs back in and then decrease them more gradually?
Yes add carbs back in. Primal does not mean low carb, especially for a hypothyroid runner!
How far and how hard do you run? For athletes Mark has recommended up to an extra 100g of carbs for each hour trained at moderate-high intensity. Depends on various factors though... "hypoothyroid" is also just too broad a diagnosis to make any specific recs.
But are you the athlete he's actually talking about in this article or are you a recreational runner?

Yeah, this is probably the case! I have about 25 lbs to lose, so that's why I thought lowering carbs would help. How do you suggest losing weight without affecting the thyroid too much?

Thank you- I'm just a recreational runner. I do about 3 moderate shorter runs (3ish miles) during the week and one long run (6-10 miles) on the weekend. I don't run very fast, ha! I'm considering cutting back on training though to see if that makes me feel better.

A brisk walk through interesting terrain burns more fuel than boring exercise. An activated brain consumes a lot of fuel.
I am a college distance runner, and eat close to 300 carbs a day if not more, all primal foods (most of the time). I tried lowish carb a few years ago when finding primal, but it was not for me. As for your weight loss, I'm not a big fan of calories but perhaps eating a bit less for a few weeks might help you the fat. Lifting and doing sprints here and there might help before you cut out calories though. Also going for a walk on top of your running might help as well.
The light amount of running you are doing might just be stirring your appetite. I run up to 70-80 miles a week at my highest training volume and I get really hungry doing it.

max is definitely right, reducing the stress of said exercise should priority numero uno
