For starters, let me give you my stats here:
Female, 19, 120lbs currently (always maintained 100-105), 5ft 1, premed/runner, no pre-existing autoimmune or hormonal conditions
Past diet history: gone from carby vegan of 3 years to zero carb keto overnight (been at it for 3-4 months)
After starting zero carb I started to see problems emerging in the 2nd month. I lost a bunch of hair (Telogen effluvium happens with a diet change so…), my skin got quite dry, my eyes got incredibly dry, eyebrows started to thin out at the sides, major fatigue, depression, cold all the time, very low body temp throughout the day, crazy weight gain… So I realized pretty quickly this sounded a lot like a thyroid issue.
Skip ahead: I got blood work done and everything was completely normal (ft4 and TSH) except for ft3… My ft3 was stunningly low. Now don’t get me wrong, avoiding carbs as we do in keto will lower ft3 because your blood sugar isn’t going crazy. However, my metabolism was botched. Not only was I not losing weight but I was gaining only eating my normal 1100-1300 calories daily (I’m a short girl so I dont need much).
Current position: I’m still researching and seeing a good functional doc to interpret more future blood test. I’m trying to fix the problem with my diet by upping carbs to 50 grams daily and so far my temp and mood has returned to normalcy but I hate the way it makes my brain feel (not as sharp). That being said I know Cytomel is an obvious fix to the low fT3 issue but it won’t cure the root cause, and being that’s it is catabolic in too high of a dosage will only worsen the metabolism if handled improperly.
So my question to you guys: how many carbs should I intake daily to raise my ft3 levels back to normal?
