A potential downside of intermittent fasting

Many people, however, have trouble going an entire day with little or no food. Krista Varady, a professor of nutrition at the University of Illinois, Chicago, has found in her research that people lose weight more slowly with time-restricted eating than other forms of fasting but that it is generally the easiest form of fasting to adopt. People tend to eat 300 to 500 calories fewer per day when they restrict themselves to an eight-hour window, said Varady, who was not involved in the new research.
