I often suggest intermittent fasting for clients who struggle with weight gain after dieting, people who want to lose weight and those who have problems with energy and cognitive problems. Intermittent fasting requires reducing the eating window during the day, typically 16 hours without eating in a 24hr window. Or eating all meals within an 8hr window.
Two trials have now completed on restricting food to an 8hr window. the first one below shows improvement in memory and planning. The other one helps keeps weight off for longer.
