I am someone with a computational physics background who is coupled with someone who is training to be a surgeon. We lived together during much of her medical school, and thus, are constantly around medical professionals.

I would absolutely trust a physicist (who has done actual empirical lab work) who has deeply studied a problem in the nutrition space over someone conventionally trained in nutrition.

You may be stunned to see how little numerical sense so many in the medical field have. And as someone who grows medicinal plants and follows that literature closely, I read tons of papers in that space. It is full of experimental design flaws and dubious correlations.

I have worked on a medical device that went through clinical trials.
