ME too.
I am 72 and my son recently lost a bunch of weight using Keto and a little fasting. He was not diabetic, but I am. I have been on Metformin (no insulin, but with progression I am sure that was coming.) I started the keto diet by simply cutting all carbs. I noticed that if you say no carbs while eating out, most places know exactly how to modify what they serve. (Bay Area). So it is easy, since I started — OK, I took a break during the holidays— but in all I have lost 40 pounds from my high and also see glucose on my tester at around 110 most mornings. (It does go as high as 146 if I have something bad the day before— recently having a hot cup of milk at bedtime has been the culprit. At any rate I see my physician next week and expect him to be surprised by my new blood numbers — No, I do not know what they are yet but I expect to continue on Metformin and keep losing weigh for another 20 pounds. We will see what has to be done to stay there, but I expect that periodic “vacations” from keto will reset the weight lost system and fasting — which I don’t normally do may also be part of the solution to not climbing back up the scale.
Eat carbs and sugars and you'll gain weight.
Don't eat carbs and you will be leaner and healthier.
