My doc told me that most of his patients would "kill" for my excellent bloodwork results.
Reduce carbs, eat veggies and fresh meat. Reduce grains (breads, tortillas, cereals and especially corn and wheat). Skip sugar(s) and sugar substitutes.
Stay away from bad oils (the ones in chips for examples).
Easy breezy.
Seed oils?
You have at least a decade on me but can say without any qualifiers that when I was on strict primal/paleo in my 40’s I was in the best health and physical condition of my life and I was an excellent athlete in my youth
Not nearly as strict about my diet these days but I keep grains, sugar, processed crap and alcohol to a minimum and my doc continues to be amazed at how good my blood work always is and the amount of strength I still have while being reasonably lean
You are obviously doing the right things
