Turtle, I know this is belated, but I'm catching up on lots of old threads I never saw the first time around. I was curious about the Newcastle protocol as well and had toyed with the idea of trying it.
But in the meantime Dr. Fung claims to be getting similar results, and his plan seemed more sustainable to me, even for a lifetime. Dr. Fung claims that limited calorie eating eventually slows the metabolism, but that actual fasting does not, and even revs up the metabolism! I'd also heard here and there that shaking up calorie intake between higher and lower also keeps the body guessing and the metabolism revved up. Instinctively I liked the idea of fasting and "feasting". So I'm trying his plan now, incorporating about 3 24-hour fasts per week, and eating "normally" the other days. Have a few days a week to eat as I choose without worrying about calories is feeling good so far, ,and I have lost 15 pounds at this point - to hit a weight I have not seen since 2012.
On the eating days I still eat in a restricted 4-6 hour window - usually with a meal about 12-1 PM, another at about 6 PM, possibly a snack in-between.
My pattern currently is:
1)"Normal Day" (yesterday "normal" first meal at 1 PM was a cheese omelet with grilled tomato, garlic and onion, coffee with heavy cream and some coconut oil) ... snack of peanut butter mixed with some whipping cream, and a dash of Candian Sugar Twin, dinner at 6 PM was a chicken sausage sauteed in coconut oil with some fresh spinach, and some full-fat Greek yogurt). After dinner no more food.
2) Fasting day ... starts with black coffee, then nothing but water, maybe tea, during the day. Then about 6 PM a tiny (300-400 calories) meal.
3) Eating day again, trying to hold off until noon st least before eating.
I don't think I overeat on the eating days, but I admit I don't count calories and that is a blessing as I hate to do that. My BG has been bad this past year and is STILL bad, but coming down quite a bit so far with this eating plan.
I think about those women who could not lose any weight on a sustained 700-calorie diet, and I really wonder what their results would have been if they had fasted with 0 calories for one day, and then eaten 1400 calories on the other day. It still would have been an average of 700 a day, but 1400 is enough to eat in a fairly "normal" fashion and not feel deprived, whereas I don't think 700 is. And fasting completely gets easier the more often you do it.
Hmm, that would be a really interesting study: two metabolically resistant groups - put one on a sustained 700-calorie diet, and the other on an alternate of 0 calories/1400 calories. Best would be in the food was identical, but one group got to eat all the food one day and none the next, whereas the other group would eat half the amount every day. Too bad no one will ever get funding for something like that! Though Dr. Johnson, in his book, says that the alternate day method yields far better health outcomes - for mice!
Dr. Eades in one of his books talked about a patient who lost weight on a LC diet but could only maintain her loss if she didn't exceed 1000 calories a day, which just felt so deprivational to her. So she ended up alternating, so that one day she ate only 500 calories,and the alternate day she ate 1500 which allowed her to feel like she could eat like a more normal person on those days. Still and average of 1000 a day and she maintained.
Hah! Very much like Fung, JUDDD, 5:2, etc. At any rate I'm trying to give Fung and alternate day fasting a good try as it seems sustainable long-term, as Newcastle doesn't.
