Some people in the looksmaxxing space intentionally eat tons of beta-carotene (carrots, sweet potatoes, juices) to turn their skin orange because they think it looks more attractive.
The thing with beta carotene is that it is not active vitamin A and must be converted into retinol.
This conversion relies on your thyroid (especially T3)
In short what this means is that: if you are actually turning orange from lots of beta carotene that is a sign of hypothyroid and poor metabolism, this is NOT what we want to see whatsoever.
This is why carotenemia has long been associated with hypothyroidism, and why doctors will immediately check one’s thyroid when they present with carotenemia.
Treating low thyroid often clears the orange color without changing the diet.
On top of this a lot of beta carotene rich foods also have notable oxalate content, which oxalate crystals also can build up in the thyroid and inhibit its efficiency.
I am not a ray peat follower whatsoever, but I agree with him on many things such as seed oils, beta carotene, etc
The thyroid is extremely important and eating lots of carrots or sweet potato’s will not be conducive to maximizing metabolism.
