My typical day of eating has been a large elaborate salad (non startchy vegetables) for one meal and beef and salmon for the second and ice coffee with stevia and cream for dessert. For the lock down I figured out how to have exactly enough fresh vegetables for 12 days of salads. When the veggies run out, instead of shopping immediately I eat all meat from the freezer for some days, may be a week or more. This averages down total carbs, reduces shopping trips and lets me buy only the food I usually eat. I wanted the ability to go 30 days without a shopping trip. I get that with extra meat in the freezer (and 6 lbs of peanut butter to stretch the meat if necessary).
With this approach I can keep both low and zero carb in play and keep learning about both.
