I did.
Reduced carbs to 20-30 a day in two- three meals of 10 carbs. Weighed and measured everything with carbs in at the start to understand quantities.
Cut out all refined carbs to begin with in the first 12 weeks. no wheat to begin with no rice, no pasta, no potatoes,no sugar.
I bought an affordable glucose checker and use this every morning.
I also use it before eating something I wouldn't normally, then check an hour after eating and then two hours after eating. The aim is to get back to the pre meal blood reading within two hours. Then you know what you've eaten is good or not for your blood sugars.
I'm stable now, 5 months in. I've also lost 50 lbs as a result because I am just never hungry with this way of eating. I love it. Delicious food.
I use almond flour in small quantities to make keto muffins and I have these each day. It works out to about a tablespoon per muffin so its ok.
I enjoy home made keto quiche, home made ice cream, home made sugar free jams. Home made keto muffins and pancakes.
You can eat vegetables (and mushrooms) that grow above ground. Meat, fish, eggs, cheese. Nuts and oils. Berries but not other fruits. And not things that grow under under the soil. I still use onions and garlic in small quantities.
I think the only down side is, diabetes is not catered for at all. You have to cook well from scratch to enjoy healthy eating. I can't choose a supermarket sandwich or sushi, I'm left with the boiled eggs and a packet of nuts.
Since stabilising I'm now using my meter to see what my body can cope with. I now know that a very small piece of fruit cake without trimmings doesn't impact my bloods too badly. But, if I add in a single strip of marzipan it's sky high for most of the day. I've found I can eat some basmati rice, but a spoonful of wheat flour will again send me sky high for ages.
Anything over 5.5 on your meter means you are sustaining cellular damage which eventually over decades results in sight loss and nerve damage. This number will jump up naturally after you eat, but the jump is only meant to be for a short while (one-two hours) whilst your body processes the food.
I'm now 4.7 in the mornings and I was 7.5 when I purchased the meter. So it can work. You can do this!
