The claim: If you dread Monday mornings, then it's probably best to steer clear of the scale. Most people weigh the most on Monday mornings and the least by Friday, according to a study published in the European Journal of Obesity. In other words, you're more likely to gain weight during the weekend and lose it throughout the week.

The research: Eighty men and women recorded their weight every morning before breakfast for nearly a year. When researchers examined the numbers, they identified a distinct trend for weight gain on weekends and weight loss during the weeks. However, they found that what sets people who ultimately lose weight throughout the year apart from those who gain is that losers shed more pounds during the weekdays. They're also more likely to adhere to this pattern than those who gain--losers hit their lowest weight around Friday 74% of the time.

What it means: Don't beat yourself up if you splurged this weekend, just get back on track by Monday morning. "There's so much more unpredictability on the weekends that makes it more difficult to stick with a routine," says study author Brian Wansink, PhD, author of Slim by Design: Mindless Eating Solutions for Everyday Life. "Weekdays tend to be more consistent, so you have more control over what you do, such as eating well and exercising."

The bottom line: "It's what you do Monday through Friday that seems to make the biggest difference in whether you weigh more or less," Dr. Wansink says. (Need to slim down fast? Find out how to Get A Flat Belly By Friday.)
