I am now fasting intermittently every day for a week-I only eat one meal at night, so I think I will fast for 23 and a half hours and eat for half an hour every day. I combine it with a ketogenic diet to make your body burn fat as fuel instead of the terrible carbohydrate/glucose/insulin program, which seems to be the reason for so many obesity/diabetes/mood swings/general unhealthy.
My personal theory is that our digestive system has not evolved to be powered by glucose, because before the discovery of agriculture 654.38 million years ago, the amount of carbohydrates was very small (just a few days ago in terms of evolution). When fat is used as a fuel source, the body/brain seems to work better (for example, there is less need to produce insulin). I suspect that we are just returning to our original lifestyle-eating a lot of fish, meat, nuts, berries, vegetables and so on.
So when I get up, I will drink a cup of coffee rich in various oils and collagen, and then have another cup in the morning 1 1, and then have a green milkshake instead of lunch. Have a cup of tea at 4 pm (after all, I am British! ), and then eat as many non-carbohydrate healthy foods (and as much wine as possible (= low carbohydrate) at dinner. Obviously, you never eat anything sugary, but your taste adapts so quickly that you don't want to eat it soon. Because you eat very little, you can buy absolutely high-quality food to fill your stomach.
So I can lose 8 ounces-1 kg every day. I think my weight will stabilize after I lose a few stones-but if not, gaining weight is not the most difficult thing in the world!
I won't go into details, but I strongly recommend the Complete Guide to Fasting written by Jason Fung. For the viewpoint of ketogenesis, please refer to leanne vogel's Ketogenic Diet. You really have to read at least these before you start, but they will tell you what to do, and they will support it with research. [Editor] An excellent book about the pure science behind the ketogenic diet (a book written by a doctor to explain to other doctors) is The Science of Low-carbohydrate Life by Jeff Swarek and Stephen D Fini. It's just about everything behind really mature science/research, but it's all better.
Most importantly, if you fast in any way, you must keep drinking plenty of water.
Good luck, if you do this research and do it-it will completely change (or even "save") your life.
