Hi, I like your way of thinking about these things. I wonder how alternate/new diets should be evaluated in the long run. Some background.
A person starts a ketogenic diet, stops eating bread. This person also switches to sea salt cuz beautiful cristals :). This particular person doesn't like fish and who eats seaweeds amirite. This person develops goitre due to iodine deficiency. I don't want to discuss the likelyhood of a ketogenic diet leading to deficiencies but I wanted to sketch a plausible scenario.
My personal interest is more from trying to grow my own food in novel ways like aquaponics. If it ever becomes a major part of my diet I should probably take nutrition into account.
What's the best way to keep healthy when going on different diets, regular checkups at the doctor for a blood work?
great questions! I might address in a future video. I'd say that that some very important aspects of health maintenance are to make sure you're getting sufficient micronutrients. and a health tracker app should give you an insight on what you are eating, make sure you're getting adequate protein. and yes, regular checkups with as many biomarkers as possible could also be insightful!
