If you're trying to lose weight, there's one simple habit that can help you see consistent results. "People who weigh themselves weekly are more successful at losing weight and maintaining a healthy weight," says Julie Upton, RD, of Appetite For Health. Want to increase your chances of hitting your goals? Fridays are a great day to weigh yourself, because it's generally when you weigh less and it can also help you stay on track over the weekend. So if you have a scale, be sure to hop on every Friday at the same time to track your progress.
