Understanding the most effective management strategy for obesity—including diet, activity, counseling, technology, acupuncture, and economic incentives—can improve clinical skills and the patient—provider relationship. This article reviews and summarizes up-to-date information on the treatment of obesity while focusing on communication and counseling techniques.
In 2013, the worldwide prevalence of obesity was 36.9% in men and 38% in women. This prevalence is significantly higher in developed countries than in developing countries and increased dramatically between 1980 and 2013.1Obesity is associated with myriad complications including an overall poorer health-related quality of life.2
Obesity is defined as a body mass index (BMI) of greater than or equal to 30. BMI is a measure of body fat based on height and weight. A healthy adult should have a BMI between 18.5 and 24.9. Overweight adults have a BMI between 25 and 29.9. Obesity is divided into 3 classes.
Obesity results in an increased risk of overall mortality and lifetime impact of disability and morbidity.3,4It is associated with a greater risk of cardiovascular disease, specifically coronary heart disease, stroke, heart failure, atrial fibrillation, and venous thromboembolism.5Obesity during pregnancy increases the risk for complications that accompany other conditions, such as pregnancy-induced hypertension, antepartum venous thromboembolism, labor induction, cesarean delivery and wound infection, and fetal and neonatal mortality.6
Furthermore, obesity and lack of exercise increase a person’s risk for type 2 diabetes as well as many types of cancers in both men and women.7,8Obesity in middle and late life is also associated with an increased risk for dementia, gastrointestinal disease, and liver disease.9-11
The primary treatment for obesity is weight loss through diet and exercise. Weight loss of 5% to 15% greatly reduces complications in obese persons.12Other strategies include behavioral and cognitive behavioral therapy.13Acupuncture and medication have also demonstrated some efficacy in treating obesity.14
When counseling obese patients, explain that their caloric expenditure must exceed caloric intake for any diet to effectively result in weight loss. Specifically, an adult can lose 1 to 2 pounds per week if they consume 500 to 1000 fewer calories per day. In general, diets that consist of low-carbohydrate and high-protein foods are associated with more weight loss than other diets.15Patients increasing their vegetable and fruit intake can help contribute to weight loss as well.16In addition, reducing the amount of dietary sugar consumed can result in significant weight loss.17Other effective ways to lose weight include following a Mediterranean diet.18,19Encouraging patients to use portion control can also be effective.20
Finally, research suggests that drinking 500 mL of water before meals results in increased weight loss in obese and overweight adults.21
The American College of Sports Medicine recommends exercise and diet to treat obesity in adults. This combination is more likely to reduce weight than either intervention alone.22Moderate intensity exercise, such as a brisk walk or a gentle swim for greater than 150 minutes per week, can result in sustained weight loss.23Although prolonged resistance training is not effective for weight loss, it can improve the patient’s cholesterol profile, insulin resistance, and blood pressure.24Furthermore, some study results suggest that lifestyle physical activity (ie, raking leaves, using stairs instead of the elevator, and brisk walking) can be as effective as a structured exercise program in promoting weight loss over 2 years.25
A 2006 study mailed surveys to US residents and asked about their successful and unsuccessful weight-loss strategies. With 6207 responses, the study results showed that the most successful strategies reported by participants included26:
Similarly, research suggests that regular self-weighing improves weight loss without increased adverse psychological outcomes.27Providing individual obesity-management education and counseling in the primary care setting can result in modest weight loss, and research demonstrates that this is actually more effective than medication.28
Counseling in the primary care setting often involves brief monthly visits that include measuring the patient’s BMI and providing diet and activity education. Advice can increase the patient’s awareness of the health risks of obesity and motivate patients to continue pursuing their weight-loss goals.
Over the past decade, numerous computer-based weight-loss programs and nutritional applications have been developed. A 2012 systematic review evaluated the efficacy of computer-based interventions for weight loss in 2537 adults. The study found that computer interventions have a modest benefit compared with no intervention; however, they are not as effective as in-person counseling from the patient’s primary care provider.29
Another recent 2016 study analyzed the main features of 13 nutrition-related mobile phone apps and compared their strategies for dietary assessment and user feedback.30This study found that a majority of apps offered a food diary, portion size selection, physical activity tracking, and motivational coaching. One app called Fat Secret connected patients with their health care provider, and another called S Health provided a unique nutrient balance score. Although research suggests that patients who use apps are not more or less likely to lose weight than those who do not, other study results reveal that combining apps with weight-loss groups leads to significant sustained weight loss.31,32
A newer approach to weight loss includes economics incentives. A 2013 randomized trial published in theAnnals of Internal Medicinecompared a control group with individuals who received $100 per month for meeting weight-loss goals and groups who split $500 per month for meeting weight-loss goals.33The study found that group-based financial incentives increased weight loss more than individual-based incentives or none at all.
Although often forgotten, acupuncture can help patients achieve their weight-loss goals as well. A systematic review published in 2009 found that acupuncture was associated with significant weight loss in obese patients compared with conventional treatments alone.34In the study, acupuncture resulted in the loss of an additional 4.2 pounds. Self-applied acupressure, on the other hand, is not as effective as acupuncture and is not a recommended treatment for obesity.35
For patients with weight-loss goals, follow-up is essential. Monthly appointments offer primary care providers the opportunity to reassess vital signs, weight circumference, and BMI and reinforce health education.
Here are the ICD-10 codes related to obesity. ICD-10 is a medical classification list by the World Health Organization:
