Intermittent fasting is not suitable for everyone – with underweight, eating disorders, pregnancy or diabetes with insulin therapy only under medical supervision. Water, tea and black coffee are allowed during the fasting phase.
Evidence: intermittent fasting shows effects on insulin sensitivity, weight and autophagy in studies. However, it is not a cure-all – most benefits can also be achieved through a moderate calorie deficit. · Sources: de Cabo R, Mattson MP. Effects of Intermittent Fasting on Health, Aging, and Disease.
