Wow, you have really committed and made a lot of excellent modifications - good for you! You get used to it. I used to detest plain water; now, it is the only thing I drink (other than a cup of coffee once a day). Still not my favorite thing, but small trade off.
I agree; fasting will always be there when you are ready to start. I think the longer you are on keto and eating sufficiently, you just morph to that point naturally. Three meals a day becomes two and usually at some point, two meals a day becomes one.
Just one last observation, I would encourage you to up your calories. I know that is contrary to everything we’ve ever done with conventional dieting. If you maintain 1100 calories per day for an extended period, you run the risk of slowing your metabolism. With that few amount of calories, it will begin to think it has to slow in order to conserve calories until the food scarcity is over. Eat to satiety but don’t count the calories. The most important thing is to keep the carbs as low as possible (total vs. net). The lower you can go under 20 a day, the more weight loss you should experience.
Good luck; hang in there!
