1. Overindulging on the weekend
To combat overindulging on Saturday and Sunday, pay attention to portion size, weigh yourself daily (or on Fridays and Mondays only) and watch your alcohol intake, which provides empty calories and lowers your food inhibitions. Researchers have found that people don’t realize they eat markedly more on weekends, particularly on Saturdays, when they tend to consume more fat. Those extra calories slow weight loss.
