Our behaviors shape our health in profound ways, influencing everything from our food choices to our physical activity levels. Understanding how these behaviors impact our bodies is the first step toward making positive changes and managing your weight and health. This article explores behavioral strategies for individuals and families, particularly within a primary care context, to promote healthy lifestyles and address overweight and obesity.
Understanding the Complexities of Obesity
Obesity is a multifaceted condition influenced by a complex interplay of genetic, biological, psychological, and sociocultural factors. Health behaviors such as eating patterns and physical activity are significantly affected by psychological and social factors. Recognizing this complexity is crucial for developing effective, multidimensional treatment plans.
The Role of Weight Stigma
Weight stigma is a significant barrier to care for obese patients. Overweight individuals are often stigmatized in American culture, including by healthcare providers. These biases can lead to patients delaying or avoiding seeking care due to anticipated disrespect, resulting in poorer health outcomes. It's essential for healthcare providers to recognize and overcome their biases to create a welcoming and supportive environment for all patients.
Environmental Influences on Weight-Related Behaviors
Environmental factors play a crucial role in determining weight-related health behaviors. These factors exist at both the microsystem level (family/social determinants) and the macrosystem level (cultural and social values). Macrosystem factors, such as the marketing of calorie-dense processed foods, and microsystem factors, such as family environment and social settings, significantly impact eating and activity patterns. Modifying these factors, such as establishing "food rules" at home (e.g., no food in front of the television), can support behavioral weight loss interventions.
Practical Strategies for Behavior Modification
Talking to Your Healthcare Provider
Discussing your weight with your healthcare provider (HCP) is an important initial step. Prepare for your visit by gathering information about your eating and exercise habits, as well as any relevant medical history.

Meeting with a Registered Dietitian
Registered Dietitians (RDNs) are nutrition experts who can provide guidance on healthy eating, meal planning, and dietary changes to improve your health. They can help you develop an individualized nutrition plan that is culturally appropriate, practical, affordable, and achievable.
Collaborative Goal Setting
Setting reasonable and achievable goals is essential for long-term success. Work with your healthcare provider or RDN to establish specific goals for physical activity, dietary intake, and weight management. Aim for a realistic weight loss goal, such as 5% of your current weight.
Accountability
Incorporate accountability measures into your weight management plan. This could involve regular check-ins with your healthcare provider, participation in a structured program, or utilizing online tools to track your progress.
Nutrition Consultation and Meal Planning
Consulting with a Registered Dietitian Nutritionist (RDN) can significantly enhance your success. RDN expertise allows for the development of an individualized nutrition plan that is culturally appropriate, practical, affordable, and achievable. The Mifflin-St Jeor equation, recommended by the Academy of Nutrition and Dietetics (AND), can be used to calculate metabolic rate and estimate calorie needs.
Self-Monitoring
Self-monitoring is a cornerstone of successful behavior therapy. Tracking your food intake, weight, and activity levels increases self-awareness of your behaviors and allows you to make healthier choices. Utilize tools like smart phone applications to record your food intake and activities.

Stimulus Control
Stimulus control strategies involve altering your environment to maximize healthy choices. This might include removing less healthy foods from your home or avoiding situations that trigger overeating.
Problem Solving
Problem-solving tactics can help you explore your weight-related health behaviors. By considering the outcomes associated with different choices, you can develop and implement specific plans for desired behaviors. Group visits can be an ideal setting for engaging in problem-solving focused on specific health topics.
Managing Social and Emotional Eating
Social Eating
Be mindful of social eating situations, especially when dining out. Plan ahead, study the menu carefully, and choose healthier options. Control portion sizes and avoid overfilling your plate.
Emotional Eating
Many people eat in response to emotions like anger, boredom, stress, anxiety, and frustration. Identify your emotional triggers and develop alternative coping mechanisms.
Relapse Prevention
Slip-ups are a normal part of making lifestyle changes. Learn how to get back on track after a slip-up and avoid turning it into a relapse. Stress management is essential for maintaining motivation over the long term. Acknowledge your successes, regularly review your progress, and reassess your goals as needed.

Dietary Approaches for Weight Management
General Dietary Recommendations
Children falling in the healthy weight category should abide by a well-balanced diet and adhere to age- and sex-appropriate dietary reference intakes. Overweight and obese children are advised to adopt dietary strategies to assist with weight reduction. These are largely regulated by parents in the home environment and include limiting portion sizes, frequency and type of snacking, restricting eating in front of the television or computer, and providing nutrient dense rather than calorically dense foods.
Specific Dietary Strategies
Focus on a healthy eating style rather than dieting. Limit portion sizes, frequency, and type of snacking. Avoid eating in front of the television or computer. Choose nutrient-dense foods over calorie-dense options. Limit consumption of sugar-sweetened beverages. Increase fiber intake through whole grains, fruits, and vegetables.
The Importance of Fiber
Adequate amounts of fiber in the diet should be encouraged when counseling children and families that are attempting to reduce weight. Estimated daily intake of fiber in children can be determined using the “age + 5” rule where 5 is added to the child’s age to obtain an estimate in grams for recommended daily allowance. Aside from the many benefits that fiber has on the digestive system, glucose levels, and LDL cholesterol, its ability to promote satiety makes it a useful tool in limiting food intake and preventing overeating. Promoting increased fruit and vegetable consumption will automatically increase fiber intake. However, it is recommended that other sources of fiber, such as whole grains
Alternative Dietary Approaches
While the use of alternative diets in youth to treat severe obesity are promising, caution should be exercised when prescribing such treatment due to the limited amount of research and the lack of long-term examination of their effects.
Macronutrient Intake
Dietary investigations examining the alteration of macronutrient intakes intend to determine the optimal composition of carbohydrates, fat, and protein for weight loss.
Physical Activity Recommendations
General Recommendations
All school-age youth should participate daily in at least 60 cumulative minutes of moderate to vigorous physical activity that is developmentally appropriate, enjoyable, and includes a variety of activities. Within each week, at least 3 days should include activities of vigorous-intensity. In addition, recent recommendations add bone- and muscle-strengthening activities for inclusion into each day’s 60 minutes of activity.
Assessing Physical Activity Patterns
Measuring the amount and frequency of physical activity patterns in youth is challenging, especially children, as most methods of estimating habitual physical activity involve questionnaires or surveys which are subjective and susceptible to recall bias. Additionally, parents are often times relied on to provide estimates of their child’s physical activity and sedentary (e.g. television viewing) behaviors.
Physical Activity for Obese Children
Obesity in children in associated with low levels of physical fitness and reduced speed and agility. Thus, obese children are often unable to perform certain physical activities as well and to the extent of their normal weight peers. As a result of their excess weight, obese children may have a greater metabolic cost or energy expenditure for executing the same physical activity than does a normal-weight child. The higher metabolic costs expended may explain why obese children may not perform as well as normal weight children during aerobic tasks.
Strategies for Increasing Physical Activity
For sedentary youth, especially those that are overweight or obese, completing an hour or more of moderate to vigorous physical activity can be challenging. For that reason an incremental approach is suggested in order to gradually increase time engaged in physical activity until the recommendation of at least 60 minutes can be achieved. Aside from using progression to accomplish daily physical activity requirements, recommendations also suggest that activities be fun, varied, and developmentally appropriate.
Developmentally Appropriate Activities
Developmentally appropriate activities are those that are suitable for the physical and cognitive development of the child or adolescent. General movement activities are great for preschool years. More specialized and complex movements, anaerobic activities are good for Pre-pubertal (6-9 years).
Weight-Bearing and Non-Weight-Bearing Activities
In addition to being developmentally appropriate, activities should also be specific to the physical abilities of children in each weight category to ensure safety and reduce risk of injury. Overweight children (85th - 94th BMI percentile) should engage in weight bearing activities such as brisk walking, field sports, tennis, and martial arts. However, as research indicates that overweight children may have difficulty maintaining extended periods of vigorous activity, pacing skills should be introduced to ensure that adequate amounts of physical activity can be performed. Obese children (>95th BMI percentile) are recommended to alternate between participation in weight -bearing activities and non-weight bearing activities such as swimming, cycling, and seated of lying circuit training.
The Benefits of Exercise
Habitual physical activity has the potential to improve many facets of physical and psychological health. Some of the benefits of long-term exercise training previously reported include improvements in lipid profiles, increases in fat free mass and reductions in fat mass, improved oxidative capacity, increased resting metabolism, increased fat oxidation, and improvements in insulin sensitivity.
Reducing Sedentary Behavior
Efforts aimed at increasing physical activity should coincide with attempts to decrease sedentary behavior. The American Academy of Pediatrics recommends a maximum of 2 hours of television viewing daily. Limiting television viewing in children is associated with decreases in BMI.
Behavioral Approaches to Lifestyle Change
The Stages of Change Model
Prior to the employment of other strategies, the first interview or meeting typically involves evaluating the participant’s motivation or readiness to change problem behaviors using the stages of change model. This model involves gauging the participant’s and sometimes parent’s readiness to change and categorizes them into one of five distinct categories: precontemplation (no intention to change), contemplation (considering to make the change but not yet committed), preparation (intention to change), action (modifying behavior), and maintenance (maintaining the behavior change).
Common Behavior Modification Strategies
Goal setting, self-monitoring, cue elimination and stimulus control, modeling, and problem solving and relapse prevention are all commonly used strategies employed in behavior modification interventions. Goal setting involves the selection of modifiable behaviors that are to be targeted by interventions and selecting specific short- and long-term benchmarks by which progress will be evaluated. The term mastery experiences entails establishing realistic, achievable, and short-term goals. These are critical in promoting the participant’s self-efficacy and facilitate the accomplishment of long-term goals. The strategy of self-monitoring requires the participant to record routine observations involving eating and physical activity patterns.
Combining Diet and Exercise
Recent research suggests that focusing on changing exercise and diet simultaneously yields better results than tackling them sequentially. This approach may be particularly useful for individuals with busy schedules who find it challenging to make healthy choices.
The Non-Dieting Approach
Recent obesity research focuses on a “non-diet” approach due to difficulty adhering to low calorie diets over the long-term. The non-dieting approach shifts the focus from weight loss to improvements in overall health. Small, manageable changes and a healthy lifestyle are emphasized rather than a sole focus on weight loss/control. Moderation leads to a balanced approach to eating and exercise. Goals include steady weight loss and maintenance of lost weight, as well as overall physical and psychological well-being. Non-diet strategies also appear to offer some protection against disordered eating behaviors (e.g., food restriction and binge eating). Non-diet interventions have lower attrition rates and longer term adherence since participants are more able to follow realistic eating plans. Intuitive eating and Behavioral Choice Treatment are examples of non-dieting approaches. Intuitive eating includes an unrestricted permission to eat. Intuitive eating allows individuals to eat for physical reasons as opposed to emotional reasons.
