I don't like to dwell on what I can't eat however but what I can eat. And that is plenty...
Eggs
Fish
Poultry
Beef
Pork
Butter (real butter)
Veggies
Salads (no dressing, just some olive oil)
Berries (with occasional fresh fruit in season)
Nuts
Cheese (cheese!)
Full-milk yogurt (never get "low-fat" yogurt)
Peanut butter | Almond butter
Dark chocolate (over 85%)
Red wine
So a lot of possibilities using the above.
I do a lot of cooking at home so don't go to restaurants nearly as much as I used to. This allows me the extra money to get quality ingredients. Also when cooking at home, I spice it up with hot peppers, garlic, mushrooms, etc. In fact, whenever I am cooking meat in the cast iron, I thrown in some onions, garlic and mushrooms with a little olive oil or butter. So good.
Another note: I see what others are saying on the thread about how overpriced food items are that are marked "Keto", "Gluten free", etc. Those labels are usually found on processed foods which I don't buy. I prefer to get the actual ingredients fresh and I put them together at home.
To eat this way successfully, you need to get away from the "stick it in the microwave on HIGH for four minutes" way of eating. You need to get those pots and pans out of the kitchen cabinets and put them to work.
I use Hershey’s 100% Cacao and Swerve (erythritol) to make all kinds of chocolate treats.
Also if you can find it in your supermarket, try Rebel Ice Cream, it uses Erythritol for the sweetener. Only 4 Net Grams of Carbs per pint! It’s not quite as good as real ice cream, but close enough.
