Kudos to you for ditching the unhealthy carbs and sugar-I’ll bet you have more energy and look terrific, too-humans were really not designed to eat all that grain-and sugar based food, and it is addictive, like drugs-fresh animals and plants suit us better.
Shop the perimeter of the supermarket. Eggs, cheese, whole-fat yogurt, nuts, fish, poultry, beef, pork, high fiber produce like berries, broccoli, asparagus, kale, brussels sprouts...all you can eat of these!
