Let’s consider the second order effects of fasting.
Inside every one of us is an anorexic and a glutton. Be wary of strengthening these aspects of your personality. If you know what I mean, then you know what I mean.
What’s your goal? Similar to knocking out a major food group, fasting can be cover for a deeper desire for chronic weight loss. Chronic weight loss is not a viable life strategy.
Health. I don’t buy the discussion on health benefits. It reminds me of counting calories => a technique, used by many, to self-rationalize poor choices.
Not smoking, reducing sugar, daily movement, wearing a seat belt… those make sense to me. Getting really, really hungry (so I can stuff myself later)… I’m not so sure.
Health is characterized by stability. Stability in body weight, sleep patterns, emotional wellbeing and cravings.
If you experience extremes in your emotional life then avoid them in your nutritional life (and everywhere else).
Own, then address, your extreme choices.
