Want to lose weight? Keep a food journal, don't skip meals and avoid going out to lunch

13.07.2012
Women who want to lose weight should faithfully keep a food journal, and avoid skipping meals and eating in restaurants – especially at lunch – suggests new research from Fred Hutchinson Cancer Research Center.
The findings by Anne McTiernan, M.D., Ph.D., and colleagues – from the first study to look at the impact of a wide range of self-monitoring and diet-related behaviors and meal patterns on weight change among overweight and obese postmenopausal women – are published online in the Journal of the Academy of Nutrition and Dietetics (formerly the Journal of the American Dietetic Association).

"When it comes to weight loss, evidence from randomized, controlled trials comparing different diets finds that restricting total calories is more important than diet composition such as low-fat versus low-carbohydrate. Therefore, the specific aim of our study was to identify behaviors that supported the global goal of calorie reduction," McTiernan said.

Specifically, McTiernan and colleagues found that:
Women who kept food journals consistently lost about 6 pounds more than those who did not

Women who reported skipping meals lost almost 8 fewer pounds than women who did not

Women who ate out for lunch at least weekly lost on average 5 fewer pounds than those who ate out less frequently (eating out often at all meal times was associated with less weight loss, but the strongest association was observed with lunch)


"For individuals who are trying to lose weight, the No. 1 piece of advice based on these study results would be to keep a food journal to help meet daily calorie goals. It is difficult to make changes to your diet when you are not paying close attention to what you are eating," said McTiernan, director of the Hutchinson Center's Prevention Center and a member of its Public Health Sciences Division.

Study participants were given the following tips for keeping a food journal:

Be honest – record everything you eat

Be accurate – measure portions, read labels

Be complete – include details such as how the food was prepared, and the addition of any toppings or condiments

Be consistent – always carry your food diary with you or use a diet-tracking application on your smart phone


"While the study provided a printed booklet for the women to record their food and beverage consumption, a food journal doesn't have to be anything fancy," McTiernan said. "Any notebook or pad of paper that is easily carried or an online program that can be accessed any time through a smart phone or tablet should work fine."

In addition to documenting every morsel that passes one's lips, another good weight-loss strategy is to eat at regular intervals and avoid skipping meals. "The mechanism is not completely clear, but we think that skipping meals or fasting might cause you to respond more favorably to high-calorie foods and therefore take in more calories overall," she said. "We also think skipping meals might cluster together with other behaviors. For instance, the lack of time and effort spent on planning and preparing meals may lead a person to skip meals and/or eat out more."

Eating out frequently, another factor associated with less weight loss, may be a barrier for making healthful dietary choices. "Eating in restaurants usually means less individual control over ingredients and cooking methods, as well as larger portion sizes," the authors wrote.

The analysis was based on data from 123 overweight-to-obese, sedentary, Seattle-area women, ages 50 to 75, who were randomly assigned to two arms of a controlled, randomized year-long dietary weight-loss intervention study: diet only and exercise plus diet. Study participants filled out a series of questionnaires to assess dietary intake, eating-related weight-control strategies, self-monitoring behaviors and meal patterns. They were also asked to complete a 120-item food-frequency questionnaire to assess dietary change from the beginning to the end of the study.

At the end of the study, participants in both arms lost an average of 10 percent of their starting weight, which was the goal of the intervention.

"We think our findings are promising because it shows that basic strategies such as maintaining food journals, eating out less often and eating at regular intervals are simple tools that postmenopausal women – a group commonly at greater risk for weight gain – can use to help them lose weight successfully," McTiernan said.

The National Cancer Institute and the National Center for Research Resources funded the study, which involved collaborators at the NCI, the University of Washington and the University of Minnesota.

At Fred Hutchinson Cancer Research Center, our interdisciplinary teams of world-renowned scientists and humanitarians work together to prevent, diagnose and treat cancer, HIV/AIDS and other diseases. Our researchers, including three Nobel laureates, bring a relentless pursuit and passion for health, knowledge and hope to their work and to the world.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
