Yeah I wish I could as well, every time I start feeling half decent, I get out some big rubber bands and try and do some shoulder and arm work as they are wasting away, the next 3
or 4 days I am in agony and can’t move 
I stopped the edibles they give me the munchies bad, something I don’t need when fasting, but my neck is probably under control better than yours as I have had 7 years of learning to deal with it lol. Wheat and corn are gut and arterial lining destroyers, especially now with all the crap that gets sprayed on it,
I also removed all refined carbs from my diet, as well as breads pasta, rice and potatoes, although if you eat cold rice and potatoes after cooking, they are a powerful prebiotic that boost gut bacteria and mitochondria and reduce blood glucose as well, instead of spiking it when eaten hot.
Heat breaks down the sugar chains and makes it easier for gut bacteria to break down when they go cold those sugar chains reform into longer than the original sugar chains and are harder for gut bacteria to break down, so they multiply dramatically and boost gut health.
You need to be careful with the calorie restrictions, it can cause your baseline metabolic rate to slow right down and when you do start increasing calories it goes straight back into storage. Although the cost of food these days that might not be so bad lol.
I was doing a 23/1 hours fast a day, but trying to get all the calories into an hour of eating hurts my stomach. You can raise the calories quite significantly, and make it very benificial to the body with extra virgin olive oil, or any food high in omega 3 fatty acids.
I also do 2 table spoons a day of MCT oil as it acts the same as key tones which your body releases when fasting more than 8 hours. Sorry if you know all this stuff already, I know you do a lot of research on things, but it might help other people reading this that want to make changes to their diets.
Internal medicine studies are now showing that key tones are actually a signal response to fasting, for the mitochondria in the body to start un coupling, as the body thinks it’s dying.
The mitochondria are a bacteria we have a symbiotic relationship with, we cant live without each other literally, and they are responsible for many body functions including making brown fat.
Brown fat is created when your mitochondria un couple and they will burn calories just for the fun of it, no exercise needed. There are other foods that cause un coupling, as well as spices, cocao or very dark 85% chocolate , fresh ground coffee, sheep and goats dairy, any fruit or vegetable that is high in coloured polyphenol’s as well as different terpenes.
I have been hitting the sheep and goats cheese hard, as well as the evoo and MCT oil, and obviously vegetables, being vegetarian, in curries full of different spices lol.
You know it’s working as your body temperature rises after digestion, it’s not just the spices that make me sweat now lol, coffee will do it about 10 minutes after drinking.
I am increasing my calories steadily now and still either losing or maintaining weight.
The more mitochondria you have in your body the healthier it will be.
, beautiful plants anyway …
