The position of the National Association of Hungarian Dietitians on intermittent fasting

Intermittent fasting (IF) is based on alternating fasting and eating periods. They focus on the timing of food consumption rather than the quantity and quality of food consumed per se. The most common versions of IF: 5:2 ratio diet (two fasting days and five eating days per week), daily alternating fasting (0-500 kcal per “fasting day” and optional caloric intake on other days), and the 16:8 time-restricted eating ( 16 hours of fasting and 8 hours of food intake within 24 hours).
