Hi aealexandrou, as I'm still learning everything about diabetes, I don't want to sound silly but what is intermitting fasting, sorry for asking but I haven't a clue ..
Intermittent fasting, also called time restricted eating, is where you compress your eating into a short window of say 8 or less hours a day. Your body is made up of trillions of cells, of which 99% will replicate and the new cell will eat the old one. Any remnants of the old cell will be stored in your fat and in theory when you lose the fat those debris will flush away in the usual way. A bad cell will replicate into an equally bad cell. You can improve it with better nutrition. The process is called autophagy. Fasting for long periods of time, say 12 or more hours will give that process a boost. If you fast for 16 hours or more you trigger stem cell growth. These are spare, completely new healthy cells whose only role is to replace bad cells. In theory they repair anything defective in your body and generally act to rejuvenate you. If your suffering from diabetic fatty liver disease, and most PreT2D and T2Ds do, then repairing your pancreas and liver are as important as reducing your visceral fat.
But IF is difficult unless your body is converted from burning sugar/carbs for energy into burning fat.
Sugar is addictive, a quick shot of energy. Your body can only use a fraction of the sugar you consume, and all carbs convert to sugar. What's not used is converted into fat, mainly visceral fat that is stored in and around, and damages your organs, particularly your liver, hence fatty liver disease which is pandemic and the precursor to diabetes. In the meantime the excess sugar hangs around in your blood keeping your insulin high. The constant built up of visceral fat and high insulin will lead to diabetes and or numerous other chronic metabolic diseases.
When you stop consuming carbs, and accordingly sugar, your body turns to burning its fat, which produces ketones. This is a more constant and efficient source of energy. Because your body has an abundance of fat, stored over many years, it can eat 24 hours a day. You stop feeling hungry because you carry your own food supply. That makes IF an easy progression.
Becoming fat adaptive is the difficult part because sugar is so addictive and your body will crave for it. Which is why I recommend a gradual progression into it by going low carb high fat, then keto. I was only on LCHF for a few days before going Keto, which I did for a week before I started skipping breakfast and then a week later lunch. I have had a 3 to 4 hour eating window now for over 4 months.
I have lost 17 kilos and came off my meds within 3 weeks. I have lost 4 inches of my waist and 1.5 inches of my neck. My blood sugar levels are normal if not better than normal and I feel substantially more energised and healthier.
I hope the above helps. Good luck.
