Nutrition, Physical Activity, and Weight Management
What the exam expects
Nutrition and activity counseling is individualized, not prescriptive. Know that there is no single ideal macronutrient distribution; Mediterranean, plant-based, low-carbohydrate, and other patterns can work when adherence and quality are supported. Understand carbohydrate awareness, consistent timing with insulin, and the role of registered dietitian nutritionists in medical nutrition therapy.
Concepts to master
- Medical nutrition therapy referral and its glycemic and lipid benefits.
- Weight management: caloric deficit, sustained loss, and the role of pharmacotherapy and metabolic surgery.
- Physical activity recommendations including aerobic, resistance, flexibility, and balance work.
- Reducing sedentary time and the post-meal walking effect.
- Hypoglycemia prevention around exercise, especially with insulin or sulfonylureas.
- Screening for food insecurity, eating disorders, and cultural food preferences.
Traps
Items may overstate the value of a single macronutrient or imply that a very low-carbohydrate diet is unsafe for everyone. Another trap is recommending exercise without adjusting insulin or carbohydrate intake, risking hypoglycemia. Watch for advice that ignores the patient's cultural foods or budget.
Rule of thumb
Prescribe the pattern the patient can sustain: emphasize nonstarchy vegetables, whole foods, and portion awareness, and pair any activity plan with a hypoglycemia safety plan when relevant.
Worked example
A patient on basal insulin wants to start walking after dinner. Counsel 150 minutes per week of moderate activity, suggest checking glucose before and after initial sessions, and note that post-meal walking lowers glucose; adjust insulin only if lows occur.
