NEW YORK (CBS) Sarah Lord is trying to lose weight.
"I'll weigh myself on Monday morning to start my week and then Saturday to see how I did at the end of the week," she said.
New research finds how often you weigh yourself may be key to weight loss. A University of Pittsburgh study shows people who weigh themselves daily are more likely to lose weight than those who don't weigh themselves at all or weigh themselves rarely.
"It would remind you to eat healthy foods, watch your calories, portion sizes, maybe stay away from those tempting sweets in the office because you know you are going to be getting on the scale the next day," said Martha McKittrick, a registered dietitian.
The study of more than 1,000 adults shows those who weighed themselves several times a week had more significant weight loss in a year. People who never weighed themselves or weighed only once a week lost no weight.
But stepping on the scale every day may not be for everyone. McKittrick says weighing yourself too often can decrease self-esteem and increase anxiety.
"If you find weighing yourself every day helps you and helps you stay on track, helps you stay focused, then I would recommend you do it. But if you find weighing yourself makes you upset or makes you lose motivation or makes you obsessed with the scale, then I do not recommend you weigh yourself every day," McKittrick said.
Lord says getting on the scale more often is more motivating.
"If it goes down great, if it goes up, you just know you need to be a little bit more strict," she said.
She's celebrating a one pound loss this week.
Experts say people who tend to obsess about the scale should also not weigh themselves every day because it could increase the risk of an eating disorder.
