I would like to know what you consider "low carb". - If you are diabetic, you are basically unable to tolerate carbohydrates, so you need to eliminate them from your diet. I suspect you are probably eating things you think are "low GI" and confusing that with "low carb".
Less than fifty grams a day, as close to zero as possible. I ate nothing but beef and eggs for two weeks one round. I eat lots of meat and eggs even when I eat more low-carb vegetables. I've done keto, even did Atkins decades ago. I weigh my non-bbbe foods, track them in carb manager. I've tried watching carbs and calories, I've watched my carbs and my fat, I've eaten lots of fatty meat and almost no carbs, I've tried not watching calories at all - just carbs, I've tried eating some low carb vegetables (mostly cabbage) but mostly beef or chicken, I've eaten nothing but chicken and eggs. I've ditched my diet coke, I've drank lots of it, I drink roughly a gallon of water a day most days. I watch my seasonings for sugar. I don't use a lot of salt, because food tastes too salty very quickly because I've never really salted my food.
I did have a few grams of carbs in my coffee creamer (I've now switched to heavy cream, then I'm going to work my way down to black), and any fillers in my meds which I can't control. But never more than 20 grams a day on my last few go rounds.
I never got into ketosis according to urine strips (I can't afford the blood meter and strips), but I did develop dka at one point and had to go to the hospital because low carb and my diabetes drug at the time don't play well together. That's not an issue now.
I am starting to think it's going to take longer for me to get into ketosis because of insulin resistance/other metabolic issues. Maybe I need to add exercise to my routine to get into ketosis. I don't know, maybe I'm full of shit about all that. I haven't committed to carnivore for a full month, I get discouraged after a couple weeks of no real improvement in glucose levels, no weight loss (or worse, weight gain), and let my addiction win. That's probably my first step: commitment to one thing and don't let my addiction win.
I no longer crave sweet foods, if I do eat them I regret it because they're all too sweet. It's not hard to avoid them anymore.
I fast until noon or later most days, I only have either one or two meals a day. I try not to eat after seven pm.
I'm very frustrated. When I lost weight last time I did low calorie, and dropped weight super easily.
