Possible Thyroid Suppression on Lo-Carb Diet

[Mehdi]

I posted on my previous thread that since I'm already prone to subclinical hypothyroidism, I was concerned that going with less carbs could've further suppressed my thyroid function and contributed to an increase in BF. Just the opposite of what I'm trying to do. I just did some research which in fact indicates that low-carb and keto diets can down-regulate T3. So, it appears to be a double-edged sword.

Even though this describes women, here's a link with more info on this:

Since I've been on a reduced carb diet within the last 60 days, I have see my weight and BF actually shoot up in exactly that time frame, despite keeping my training the same, although I did have to cut back on my cardio temporarily and now I'm back on it which makes it difficult to ascertain, as it could be a combination of both. The only positive is that my strength and size has increased, but at the expense of higher BF also.

I have run the Cunningham figures as listed. I think more of the issue right now is the concern as to the effects of impaired metabolism on a low carb diet as opposed to assessing caloric needs.

I am at a loss as to an answer or a solution right now.

Do I go back to what I was doing before the gain (I was eating oatmeal with my protein on the first meal and maintaining)?

Lots of supps (too many to list), green & black teas, and lots of spices (cayenne, curry, tumeric, cinammon, etc.)

In addition to the sluggish thyroid, I should also mention that my free testosterone levels were a bit on the low side and estrogen levels have been elevated in the past. I will be re-testing all hormones, IGF-1, and a bunch of other ones to see where I'm at.

I'd appreciate any and all input.
