Sigh, While what you say it technically true life isn’t always so black and white. I don’t find blanket statements like that useful although I am sure they are well meant. Yes, technically I can fast anywhere, and certainly I do when traveling, especially by plane. (and Jason Fung also speaks of how there is a time for fasting and a time for feasting, life is not all fasting)
However in my job there are times where I can’t/won’t just skip meals as meals are part of the job. Do nothing is not a wise choice for other reasons for me in these instances.
I have been off sugar since 2002. that’s right 17 years this summer. I know how to hold onto an important health decision and I also know, again for myself, that life is full of compromises because other things are important to me as well. Like my career and my family’s feelings on holidays.
