I'd say that's probably a very alarming trend in the youth to pick for a quick fix with things regarding weight loss, but I wouldn't pin fasting as an unhealthy practice. There have been plenty of studies done on the effects of different types of fasts (IF and water fasts) and those results are promising. There was even a clinically monitored year long fast with the test subject coming out without any health problems in the end. I think the studies suggested in this article has a fallacy of assuming that fasting is inherently wrong. Reminds me of the demonization of fats and dietary cholesterol still rampant today.
