Your BMI sound quite good, like PauIL said, we believe your shape must look good, so you donât need to worry about your weight, perhaps you can share some of your photos here if you donât mind, I believe you will get confidence here by posting your photos.
I am an Asian as well, actually Im a Chinese. And I am also doing OMAD almost 5 days a week, and I found that doing OMAD made me feel bad sometimes especially after 1:00 PM. So if you feel bad on OMAD, I suggest you to stop it, if you dont want to stop, then I suggest you to supplement electrolytes during OMAD and reduce water intake during OMAD, it helped me feel better during OMAD. You can read my posts about my bad feelings on OMAD (including shortness of breath)
And I believe OMAD is the cause making you feel bad, you can try to continue carnivore but without OMAD, it might help you.
Furthermore, from your typical foods intake, I can know that you donât eat dairy foods, that means you are almost 0 carbs. And as I know, many women including my wife cant feel good with 0 carbs, especially for us Asians. My wife was doing low carb as well, and she was doing very well, but 0 carbs made her feel bad, she still eats fruits sometimes, and her weights maintained quite well. Why donât you try to add some carbs back to your diet?
