Dear JJ: My functional medicine doc has me doing intermittent fasting twice a week, alternated with a Paleo-type diet the other five. I lost weight at first, but then I developed insomnia. Do you find intermittent fasting helpful or harmful in the long run?
As its name suggests, intermittent fasting (IF) alternates eating with not eating. Do a quick Google search and you'll find numerous IF plans, often by bloggers enthusiastically singing its praises for fat loss, boosting immunity, and otherwise favorably impacting health.
