What are the guidelines for lifestyle medicine to adopt a healthier lifestyle?

Lifestyle Medicine Guidelines for Adopting a Healthier Lifestyle

All adults should adopt a comprehensive lifestyle approach that includes a heart-healthy dietary pattern (emphasizing vegetables, fruits, whole grains, low-fat dairy, fish, legumes, and nuts while limiting sweets, sugar-sweetened beverages, and red meats), at least 150 minutes per week of moderate-intensity aerobic exercise, sodium restriction to less than 2,300 mg daily, weight management targeting a BMI of 25 kg/m², alcohol moderation, and smoking cessation. 1

Core Dietary Recommendations

Heart-Healthy Eating Pattern

• Consume a dietary pattern rich in vegetables (8-10 servings daily), fruits, whole grains, low-fat dairy products (2-3 servings daily), poultry, fish, legumes, nontropical vegetable oils, and nuts 1
• Limit intake of sweets, sugar-sweetened beverages, and red meats 1
• Follow established patterns such as the DASH diet, USDA Food Pattern, or AHA Diet, adapted to personal calorie needs and cultural preferences 1

Specific Macronutrient Targets

• Reduce saturated fat to 5-6% of total daily calories (or less than 7% for LDL-C lowering) 1, 2
• Eliminate trans fats from the diet 1
• Limit dietary cholesterol to less than 200 mg daily for those requiring LDL-C reduction 2
• Add plant stanols/sterols (2 g/day) and increase viscous fiber to 10-25 g/day for additional cholesterol lowering 2

Sodium and Potassium Management

• Restrict sodium intake to less than 2,300 mg per day; further reduction to 1,500 mg/day produces even greater blood pressure benefits 1
• Even reducing sodium by 1,000 mg/day without achieving these targets will lower blood pressure 1
• Increase potassium intake through dietary sources 1

Physical Activity Requirements

Aerobic Exercise

• Engage in at least 150-300 minutes per week of moderate-intensity aerobic activity (such as brisk walking, jogging, cycling, or swimming) on 5-7 days per week 1, 2
• Alternatively, perform 75-150 minutes per week of vigorous-intensity aerobic activity 1
• For blood pressure and lipid management specifically, aim for 3-4 sessions per week lasting 40 minutes per session of moderate-to-vigorous intensity exercise 1

Resistance Training

• Perform dynamic resistance exercises on 2-3 days per week to improve metabolic parameters and blood pressure 1
• Avoid isometric resistance training due to limited supporting data 1

Weight Management Strategy

Target Goals

• Achieve and maintain a BMI of 25 kg/m² with waist circumference less than 102 cm in men and less than 88 cm in women 1
• For those with excess weight, target 5-10% weight loss within 6 months, which yields significant clinical improvements 1, 3
• Create an energy deficit of 500-750 kcal per day (total intake of 1,200-1,500 kcal/day for women) through caloric restriction 1

Behavioral Strategies

• Implement SMART goal setting (Specific, Measurable, Achievable, Realistic, Timely) with regular self-monitoring 1
• Use behavioral techniques including stimulus control, problem-solving, assertiveness training, slower eating, reinforcing changes, and relapse prevention 1
• Consider comprehensive cognitive behavioral interventions to increase engagement, retention, and adherence 1

Alcohol and Tobacco Management

Alcohol Consumption

• Limit alcohol to no more than 2 drinks per day in men and 1 drink per day in women (or 20-30 g ethanol/day for men, 10-20 g/day for women) 1, 2
• Small amounts of alcohol are unlikely to negatively affect health outcomes, though individuals with certain conditions (rheumatoid arthritis, gout) may experience flares with moderate consumption 1

Smoking Cessation

• All smokers must receive advice to quit and be offered assistance with cessation 1
• Smoking cessation is a non-negotiable component of lifestyle medicine 1

Implementation Framework

Multicomponent Approach

• Lifestyle interventions should be multicomponent, including diet, exercise, and behavioral strategies delivered over at least 6-12 months 1
• Provide individual or group sessions with trained interventionists 1
• After initial weight reduction, implement long-term maintenance measures with at least monthly contact (in-person or by phone) for at least one year 1

Patient-Centered Considerations

• Health professional interactions must be respectful, patient-centered, and value individualized preferences considering cultural, socioeconomic, and ethnic differences 1
• Address psychological factors including anxiety, depressive symptoms, body image concerns, and disordered eating to optimize engagement 1
• Avoid weight-related stigma and be sensitive to marginalization 1
• Use adolescent and ethnic-specific BMI and waist circumference categories when appropriate 1

Clinical Counseling Strategy

• Apply the 5A Model (Assess, Advise, Agree, Assist, Arrange) for efficient lifestyle counseling at every clinical visit 4
• Recognize that healthy lifestyle benefits can occur even without weight loss 1
• Partner with patients in shared decision-making, acknowledging that lifestyle modifications are equally effective in various populations as in the general population 1

Monitoring and Follow-Up

Assessment Timeline

• Repeat evaluations at 4-6 weeks after initiating lifestyle changes, then again at 12 weeks 2
• Continue ongoing assessment and monitoring during both weight loss and maintenance phases 1
• For those on medications, lifestyle modifications enhance medication effectiveness and may reduce medication requirements 1

Referral Considerations

• When complex issues arise, refer to appropriately trained allied health professionals (dietitians, exercise physiologists, behavioral health specialists) 1
• Recognize that lifestyle management is the joint responsibility of all health professionals partnering with patients 1

Special Population Considerations

• Ethnic groups at high cardiometabolic risk require greater consideration in lifestyle interventions 1
• Children and adolescents should avoid restrictive dieting behaviors; focus discussions on achieving and maintaining healthy lifestyle rather than weight 3
• For patients with rheumatic and musculoskeletal diseases, work participation should be discussed as it may benefit disease outcomes 1

Critical Pitfalls to Avoid

• Do not prescribe overly restrictive diets or excessive exercise requirements that are unsustainable; moderate goals are more achievable and appropriate for long-term success 5
• Do not ignore psychological barriers to lifestyle change; addressing mental health is fundamental to adherence 1, 4
• Do not implement lifestyle changes without considering medication interactions, particularly with iodine-containing foods in thyroid disorders 6, 7
• Do not focus solely on weight as the outcome measure; health and quality of life benefits occur independent of weight loss 1
