Fair enough Neill, although that would be at least a 32 hr fast (assuming sleep time of 8hrs) - which is a long time for a body to go without energy intake after a lifetime of much more regular meals.
Also, I take it that the 'precipitous weight loss' included LBM as well as bodyfat?.
And given my earlier comments about how long term IF seems to increase the efficiency of food utilization, I'm wondering why you (or Robb) think less frequent longer fasts, rather than daily fasts of only incremental extension of your customary overnight fast is the optimum way to realize the considerable health and body comp benefits IF confers.
In other words, precipitously embarking on much longer overnight fasts, however infrequently, seems like a sure way to stress your metabolism. Some individuals more than others of course. Many people seem able to move into daily at least 15 hr fasts with only benefits. Your experience with such a sudden transition into a much longer fast seems to indicate that you and I are both definitely in the 'gradual is far better' camp.
Whatever the overnight fast length you have been getting for most of your life - be it 8 hrs or 12, why don't you just extend that by half an hour a week/ fortnight? and see what happens, rather than just stressing it less often?
