When I experimented with Keto and Carb Cycling in the past, I kept it simple by eating ground beef, veal, turkey, pork, or chicken to make lettuce burgers or wraps, even meat loafs on the go. I also ate steak, bacon, eggs, and varieties of fish. Ensure that you take adequate amounts of vegetables to satisfy your micronutrient needs along with your multi and other preferred supplements. If you aren't getting enough fibre, you can use fibre supplements or other natural sources like psyllium husk, etc. Also, try to vary your fat sources. I used a lot of coconut oil for frying as it contains a lot of nutritional benefits you can easily google.
