I was getting into twitter again the past couple of weeks (an addictive and compulsive behavior that I should probably stop).
There was one thread where people were listing doctors and health care personalities that they deemed “quacks”. One woman insisted that Dr. Fung was a quack and that any form of fasting for health was, by definition, an eating disorder. I asked a few mild questions for clarification and got blocked. Apparently people take this stuff rather personally or seriously.
I believe that people with a history of eating disorders should probably tread lightly and check with their doctors before starting fasting. It makes sense that it might trigger old behavior. But I don’t see it as unhealthy for people who don’t have this background.
Of course, the “Intuitive Eating™” people seem to see any form of restriction (time, type, or quantity) as undesirable manifestation of “diet culture”. To them, intermittent fasting is an eating disorder, keto is overly restrictive, and wanting to change your diet for health or weight loss reasons is toxic behavior. I find it rather extreme.
