Gremlin - congrats!! I agree with you and have excluded all carbs (at least those I can control) from my diet. There are tiny bits in everything though including meat so keeping below 20 grams a day is sometimes tough. I do lazy keto and just stick to things I know are all right and it generally works out. I don't bother using keto stick but instead, watch my weight. If I creep up a kg then I get more serious. I can balance it with exercise and in general burn 1,000 calories a day and can kick it up higher if I put on a kg. I believe that you begin to start making insulin again when your carb reserves get back above 1,800 calories worth or if blood glucose goes above 110. If the blood glucose can be controlled by diet from never exceeding ~110 then the body won't produce any insulin. Without insulin, you can't store fat at all. So, the secret to keto is actually controlling blood sugar. It doesn't take much to cause a burst of insulin and eating some foods causes the mind to do it without any sugar at all. Chemical additives, and in particular some artificial sweeteners actually cause insulin to spike without any carbs at all. I eat nothing that has any preservatives and only use Stevia or erythritol (both natural) as sweeteners as they have been proven to not cause an insulin spike. Starch is hard to control and I don't use any to cook with. I use tapioca flour or arrowroot flour as thickeners.
The key is to not make insulin at all and to eat in such a way that your blood glucose level never goes up. This is not a simple task. This is partially why I am doing OMAD and exercise hard to burn off any carbs that may have accumulated thus forcing ketosis. The process of autophagy won't begin until the body is convinced it is starving and then it begins to eat itself which is a good thing as it begins with damaged cells and organelles. This is why fasting has a direct effect on longevity. If you do keto correctly then you are in a state of fasting for roughly 12 hours a day and then can derive the benefits from autophagy. The alternative is to fast 24 hours once a week which is very hard.
A person on the keto diet actually doesn't get hungry at all. If you have hunger cravings it means you are out of ketosis and have insulin present. Insulin has a direct effect on the hormones that cause hunger and cravings. I am not hungry at all until I start to eat and then a few minutes later I am ravenous. This is a sign I am having insulin problems. I then have to get serious again and start counting the carbs and calories. My larger problem when I am doing it right is to force myself to eat enough as I just am not all that hungry and get full quickly.
