The idea of intermittent mini-fasting seems to be gaining traction. The appeal: Dieters have to restrict calories for only two days a week. Research suggests this approach is more effective than trying to cut back on calories 24/7.
In a Spanish study, overweight people who ate most of their calories before 3 p.m. lost significantly more weight than their counterparts who were nighttime eaters. So watch those calorific midnight snacks.
