For a few years now, I was back on a "normal" ( will kill you) diet. It took two years of extreme low carb diet to lick the fermenting gut, and after that, it was a huge relief to eat what I wanted again. I would not wish that diet on anybody not dying, trying to cut carbs to 10 grams or less a day to starve the bad yeast out of my body was very harsh. Normal RDA for carbs is 250 g.
I've been prediabetic since about 35 btw, but never quite crossed the line. Now I'm old and prediabetic, and still have the chronic fatigue syndrome from the west nile. Inability to work off the pizza and enchiladas jacked up my lipids enough to even scare me.
So here I go again with the diet starting about two weeks ago, knew it was coming. What I'm trying to do now is just keep the carbs way below the 250 gram RDA. I'm just trying to eat carb free most of the day, then when I can't stand it later in the afternoon, I let myself finally have some carbs. That way the dinner menu is not so restricted. This tricks my liver into releasing some of its hoarded sugar every day, and even change some liver fat into sugar to be burned. Then at night, instead of pumping out fat into my blood, it will store it in my liver. The first weeks suck, your liver says f u, and you low sugar bonk. The liver is stubborn, and has to get trained you are serious. At first its sure you will break down and have that donut. But once it gets trained, the liver will give. Then you stop bonking every morning.
I'm aiming for about 50g a day for long enough to shed at least 5 pounds, then try to stabilize at somewhere around 100 average. So like 50 a day most days, then pizza night I have a few hundred grams of carb credit. Its hard.

But doable compared to the 10 grams of carbs a day I was on for years. FWIW, I'm not counting complex carbs into that 50, like the cottage cheese, the nuts, the carbs in a carrot, etc. I'm just counting the high glycemic stuff. The slices of bread, the tortilla, potato chips or fries, stuff like that. One sandwich, including the miracle whip on it, 30 grams. After that, any chocolate, or dollop of ice cream, I'm at 60 grams. So I will have to skip the sandwich a day or two to have a Mexican plate with enchiladas, beans and rice. My staple meal is veggie hash. Some kind of meat and mixed vegetables, fried in olive oil. Tasty, but it does need potatoes to taste better.

Breakfast I skip, but alternative to hash is omlette, which is 90% same as a stir fry, but with and egg instead of the rice. I like tons of spinach in those omlettes.
With any luck, and some statins, I can get my lipid numbers down to where I can eat a normal but healthier diet. I'm guessing this would be more like 150 grams a day average, allowing a lot less budgeting to eat some carbs every day. But still crossing potatoes in any form off the list for the most part. Rice instead is the idea. Bear in mind, without the CFS, I would be able to just go pedal off a bag of potato chips, like I did for 50 years. I have to diet better, since I cant do hard exercise without severe reactions to it.
