I began with almond butter, high-fiber crispbreads, broccoli, tuna, egg whites, poultry, beef, whey, strawberries, red wine, and supplements. I kept my net carbs @ ~50 grams/day for a year.
I’m now about ~90 grams/day on net carbs, but I’ve been gaining weight because my calorie intake is too high.
The typical food store is unfortunately selling a tremendous amount of sugar in the center aisles.
For years, I've been shopping the perimeter of the supermarkets. All the fresh foods are located there. I dart into the aisles only to get specific items like canned sardines or spices. Much healthier as a result and I get in and out of there quickly.
