I've also seen talk about vitamin B2 (riboflavin).
B2 might help against hyperhidrosis. Meat has B2, so maybe you crave meat for that reason. You can try avoiding meat but taking a B2 supplement. Then you might wonder what causes a B2 deficiency, such as a gut problem, or too much alcohol.
Good luck.
ida, if your urine does not contain excess TMA, then next we'd wonder if your odor is instead caused by sulfur containing compounds like methanethiol. That can be the result of eating too much meat. This can especially be true if the odor is more sour than fishy. This condition also can interact with gut bacteria.
Luckily for you, the "carnivore diet" (CD) is now very trendy and so there are many discussions about the effect on body odor. Some say the CD causes body odor while otherwise some say they instead get better and no longer use deodorant. So as you know, we must distinguish between odor caused in them by bacteria on the skin, versus odor caused by substances secreted by your skin.
So there is a lot of individual variability among people, in response to an all meat diet.
Here's a youtube on CD with lots of comments: "Eating meat makes you STINK! #carnivorediet " https://www.youtube.com/watch?v=0lc0x6WWz3I
Here's a keto diet forum (but don't get distracted by talk of smell from ketones): https://www.ketogenicforums.com/t/body-odor/88611
If you *very* strictly follow the institutional diet and the odor and gut problem goes away, then the next step is to one-by-one introduce things like a spice to see if they are allowed.
You are also very likely aware that some doctors will say it is all in your imagination. We know that's not true if other people are always telling you about the odor.
Hello, Ida. Why are you not centering your thinking on the choline in foods? Eggs, fish, some meats, garlic, onion, dairy.
And then because of eating choline, to accumulation of the smelly trimethylamine (TMA) which eventually gets secreted in your sweat. I'd think of TMAU more than PATM.
Yes it is very complicated because gut bacteria is also heavily involved. And btw, choline as in phosphatidylcholine is used in skin care products.
I assume you are aware of researcher Irene Gabashvili and her website and facebook group. Plus her **** (Methyl-Bile Acid Oral) approach.
I see that the PATM group on medhelp is surprisingly active. But in a quick look I didn't see them discussing TMA there.
Or as Annie suggested, for simplicity just reproduce your diet as in your both times on institutional food. As *exactly* as possible, especially the low spice you mentioned in your other thread. Then you might be a lucky one who again and again gets complete absence of the problem whenever you wish. That might be very difficult to accomplish voluntarily, but is still a simple concept and doesn't even require any doctor or tests.
Your food restriction to one-meal-a-day wasn't restrictive enough, as you found. But it's not so much about frequency, as about the contents of your food. Choline and maybe CARNITINE (and carnitine is especially in meat, as in the word carnivore).
In your personal life now, do you again eat the way you did when you were a teenager (one meal a day), or do you have three meals a day like in the hospital that time? Have you ever tried mimicking the hospital's food pattern that made you feel like people liked your smell better, to see if it changes your smell again? Often people get a body smell from something like a malfunctioning kidney or liver; has your doctor ever run tests on your internal organs and how they function?
