I’ve tried fasting from time to time. The really odd thing to me is that if I were going to the hospital and the doctor told me not to eat anything for 24 hours, I would have absolutely no difficulty following the orders . To do the same thing on my own initiative isn’t so easy, however.

Best to try to get into ketosis before starting your fast to prevent a huge down swing. For anyone interested a nice summary of some ideas listen to his Tim Ferris Podcast interview: http://fourhourworkweek.com/2015/11/03/dominic-dagostino/
That being said. Low Carb, Ketosis and Fasting all have different pros and cons and can be used for different results.
