What way of eating are you following at the moment?.. if you have already cut carbs down a lot you will find fasting a lot easier than if you are still consuming carbs. maybe start with skipping one meal per day (for me breakfast) ideally at the start or end of the day i.e. breakfast or dinner. This extends your nightly fast (sleep) and gets the body used to doing without food.
I found bfast the easiest meal to skip and as it was usually for me carb heavy the best one to stop having. You may find it better to skip dinner.
Once you've done a couple of weeks of this and are comfortable maybe go for a 24 hour fast.
I've only been doing this for about 6 weeks but the most surprising thing is that I've lost 6 kilos ! Only another 10 to go and I'll just be overweight not obese. And I feel great for it. I know I've not been particularly scientific about this but I've just completely cut out bread, potatoes, pasta, rice, couscous, sugar, beer, processed food and most other root vegetables. Using the recipes on this site makes it easy, I'm eating well !
My normal breakfast was a banana, home made full fat yoghourt and black coffee, although the banana has been left out for the last month. Lunch was usually a sandwich of some sort but for the last 6 weeks it's been a portion of pate or cheese with a few olives or tomatoes or pickles. However, this week, I've found it relatively easy to skip lunch and just get by on a light breakfast and my evening meal, which is nearly always chosen from the 365 Recipe Book.
But I think that perhaps having even a small breakfast is inhibiting the fasting process so I'll try going without it for the next week or so. I'll just have my yoghourt as a dessert after my evening meal. So, in effect, I'll be extending my night time fast by another 9 hours.
Most of the time, my blood glucose level hasn't risen by over 2mmol/l two hours after eating, but my fasting blood glucose level has, if anything, started to creep up from around 6.0mmol/l to about 6.5mmol/l.
Just to add a little complication to it all, I've also been blessed with ulcerative colitis for the last 20 years. Sometimes it's been really grim but it also went into remission for over five years when I retired. It comes and goes as it pleases and at the moment it's just at the somewhat irritating stage, in other words, my colon is slightly inflamed. I'm allergic to the commonest medication so I don't take anything at all for it. If it gets really bad I follow a FODMAP regime until it calms down. Touch wood, it's been over 15 years since I've had to resort to steroids. There are a lot of very interesting posts about diabetes and colitis on this site.
I must say that these forums are great, surely
this is what the internet was for !
