I had two websites that got hit last year in the medic update.One helpful point to understand is that the so-called "Medic Update" really had nothing to do with sites that cover health related topics such as you describe. This means you might be focusing on traffic loss from the wrong angle.
I have said all along that the medical targeting and the "authorship" targeting seemed a bit off and did not correlate with what I was seeing. That's because I was looking at it from the lens of Relevance, not trying to find what Google was targeting. And I was correct. John Mueller explicitly said that the algo did not target medical sites.(my bolding) can help in seeing your question differently and maybe finding a solution.
Do you intend to mainly choose topics that have the potential to attract a lot of search traffic?

Do you have a degree in healthcare, or are you otherwise qualified to tell people what's best for their health and fitness? Being interested in health is not enough. Health queries probably require more authority from web pages than other queries, because there's a lot of speculation and misinformation in that industry. If you can't convince Google you're an authority, you're not going to compete.
"Why X is good for you" and "Best X powder" type of articles are a dime a dozen anyway. I wouldn't bother.
