Want to Lose Weight? Weigh Daily

New research suggests a simple action can help a person lose weight and keep it off.

Merely stepping on the scales and writing down, or graphing the results, has been found to be an effective method to lose weight especially for men.

In a two-year study, Cornell University researchers found that frequent self-weighing and tracking results on a chart can pay big dividends.

The study is published in the Journal of Obesity.

Investigators found that subjects who lost weight the first year in the program were able to maintain that lost weight throughout the second year.

This is important because studies show that about 40 percent of weight lost with any dietary treatment is regained in one year, and almost 100 percent of weight loss is regained at the end of five years.

“You just need a bathroom scale and an excel spreadsheet or even a piece of graph paper,” said Dr. David Levitsky, professor of nutrition and psychology at Cornell and the paper’s senior author.

The method “forces you to be aware of the connection between your eating and your weight,” said Levitsky. “It used to be taught that you shouldn’t weigh yourself daily, and this is just the reverse.”

In the study, 162 subjects were randomly separated into an intervention group and a control group. Individuals in the intervention group were first given a target of one percent weight loss, which they could lose in any manner they chose.

“Because we didn’t prescribe, everyone found their own way of losing the weight,” whether they reduced portion size, stopped snacking, or skipped a meal, Levitsky said. Losing one percent of body weight requires most people to cut only about 150 calories a day for two weeks.

Once they maintained that weight loss for 10 days, the program then gave them a new target to lose another one percent, and so on. The goal was to lose a total of 10 percent of their starting body weight.

Still, there was a significant difference between men and women, with women losing weight on the program, but far less than the men.

“It seems to work better for men than women, for reasons we cannot figure out yet,” Levitsky said.

Overall, the researchers believe that stepping on a scale and tracking one’s weight acts as a reinforcement for some behaviors, such as eating less, and it strengthens others such as going for a walk in order to maintain body weight.

“We think the scale also acts as a priming mechanism, making you conscious of food and enabling you to make choices that are consistent with your weight,” Levitsky said.
