Why Is Lifestyle Weight Management Important?

Improved metabolic control Lower fasting blood glucose and prevent T2D Lower blood pressure and lipid profile Reduce need for pharmacologic therapy for metabolic

complications associated with obesity

Improved quality of life Less musculoskeletal weight-bearing joint pain Improved GERD, OSA, reactive airway disease

Increased life expectancy Lower incidence of certain cancers

GERD = gastroesophageal reflux disease; OSA = obstructive sleep apnea; T2D = type 2 diabetes.

Reduced Calorie Meal Plans

7Gonzalez-Campoy JM, et al. Endocr Pract. 2013;19(suppl 3):1-82.

A negative energy balance is necessary to achieve weight loss

Recommendation

Generaleatinghabits

Regular meals and snacks; avoid fasting to lose weight Plant-based nutrition (high in fiber, low calories, low glycemic index,

high in phytochemicals/antioxidants) Understand Nutrition Facts Label information Incorporate beliefs and culture into discussions Informal physician-patient discussions Use mild cooking techniques instead of high-heat cooking

Page 8: How Do We Treat Obesity?...Achieve Weight Loss Goals INTENSIFICATION Impart skills and behavior change to induce and maintain weight loss Simple advice to lose weight in doctor’s

Nutritional Components

8Gonzalez-Campoy JM, et al. Endocr Pract. 2013;19(suppl 3):1-82.

Recommendation

Carbohydrates

Understand health effects of the 3 types of carbohydrates: sugars, starch, and fiber

Target 7-10 servings per day of healthful carbohydrates (fresh fruits and vegetables, pulses, whole grains)

Lower-glycemic index foods may facilitate glycemic control:* multigrain bread, pumpernickel bread, whole oats, legumes, apple, lentils, chickpeas, mango, yams, brown rice

Fat

Eat healthful fats: low-mercury/low-contaminant-containing nuts, avocado, certain plant oils, fish

Limit saturated fats (butter, fatty red meats, tropical plant oils, fast foods) and trans fats

Use no- or low-fat dairy products

Protein Consume protein from foods low in saturated fats (fish, egg whites, beans) Avoid or limit processed meats

Micronutrients

Routine supplementation not necessary except for patients at risk of insufficiency or deficiency

Chromium; vanadium; magnesium; vitamins A, C, and E; and CoQ10 not recommended for glycemic control

*Insufficient evidence to support a formal recommendation to educate patients that sugars have both positive and negative health effects.

AACE Recommendations for Physical Activity Individualize

recommendations according to patient goals and limitations Activities/exercise within

capabilities and preferences Evaluate for

contraindications and/or limitations to increased physical activity before beginning or intensifying an exercise program Set realistic goals and

schedules

Encourage increased nonexercise physical and leisure activity Taking stairs at work,

weekend recreation Consider involvement of

an exercise physiologist or certified fitness professional To individualize physical

activity prescription To improve outcomes

Page 22: How Do We Treat Obesity?...Achieve Weight Loss Goals INTENSIFICATION Impart skills and behavior change to induce and maintain weight loss Simple advice to lose weight in doctor’s

AACE Recommendations forAerobic and Resistance Training

Aerobic Training

Goal ≥150 minutes/week* Greater moderate intensity (ie,

“conversational”) physical activity (eg, brisk walking)

Start slowly and build up gradually Additional 1-3% weight loss seen

when higher intensity aerobic activity is added to a weight loss diet plan

Resistance Training

2-3 sessions weekly* with major muscle groups

Start slowly and build up gradually

Results in improved body composition and metabolic risk factors Greater fat loss and less fat-free

mass loss

22Garvey TW, et al. Endocr Pract. 2016;22(suppl 3):1-205.

*Higher volume required for weight maintenance

Advice for Physical Activity

24Handelsman Y, et al. Endocr Pract. 2015;21(suppl 1):1-87.

Intensity• At least moderate, physical

activity (conversational—should be able to talk comfortably)

• Heart rate ≥70% of maximum heart rate (max heart rate =220 – age)

Frequency• ≥3-4 times/week• Maintain a regular schedule with

realistic goals)

Motivation• Cross-train (ie, walk, ride, swim)• Use a physical activity partner or

professional trainer or attend organized programs

• Reward self

Support• Health care professional team

must exude positive attitude regarding importance of physical activity

25

Advice for Physical Activity

Hydrate Drink fluids (>18 ounces) 1-2 hours before exercise

Stretch Include warm-up and cool-down periods of 5-10 minutes each

Dress comfortably Wear silica gel or air midsoles and polyester seamless socks

Be safe Check for blisters before and after activity

Patients with T2D, neuropathy, or vascular disease Wear an ID bracelet if needed

Have fun Aerobic and resistance training are both beneficial Be active with a friend

Any activity is better than no activity!

All patientsLow-impact activity: stationary bicycle, swimming, elliptical machine, stairstepper, treadmill, low-impact aerobics, weight-lifting machine

Foot disease, peripheral vascular disease, arthritis

Swimming, water aerobics, upper body resistance training

Orthostatic conditions

Semi-recumbent chair and weight lifting, semi-recumbent cycling, water exercise

Elderly Stretching while sitting, elastic bands, movement exercise (eg, tai chi, hatha yoga)

Set Realistic Goals With Your Patient

42

GOAL: decrease risk of complications and improve long-term health

Advise patients to accept steady, incremental progress and emphasize that improved health—not necessarily reduced weight—is the goal• Short-term weight loss goal (for most patients): 7% to 10% loss at 6 months

• Increase in muscle mass may be more important than decrease in fat mass• Interim goal: weight maintenance• Long-term goal (if desired): additional energy deficit recalculated for the next

weight loss goal

Remind patients that reducing caloric intake and increasing physical activity are key to achieving and maintaining weight

Ask patient: What are your goals?

Patients often want to lose ~30% of body weightA weight loss of “only” 7-10% may be deemed as “failure” by patients

Motivational Interviewing

Definition

A guiding style of communication that helps Engage patients in self-care Clarify their strengths and

aspirations Evokes their own motivations for

change Promotes autonomy of decision

making

Technique

Ask Use open-ended questions to

invite the patient to consider how and why they might change

Listen Understand the patient’s

experience Summarize with reflective

listening

Inform Ask permission to provide

information Ask what the implications might

be for the patient

Early Weight Loss Supports Long-Term Success

Weight loss of >2.5% in the first month of the DPP predicted long-term weight loss success Stepped care approach involves education on

problem solving skills and evaluation of outcomes Intensify behavioral lifestyle intervention if patients do

not achieve a 2.5% weight loss in the first month Intervention and support should be tailored to each

patient’s ethnic, cultural, and educational background

Monitor Weight and Reinforce Weight Loss Goals During Follow-up Visits

Monitor and discuss weight status at each visit—open communication is vital Encourage self-monitoring of healthy eating and

regular physical activity Remind patient of health benefits of maintaining a

healthy weight Reinforce realistic short and long-term expectations Encourage continued adherence to healthy lifestyle

and behavioral changes

Lifestyle Therapy Summary

Lifestyle interventions effectively prevent physical and metabolic complications of obesity Lifestyle alone is less effective in populations with higher

stages of obesityWeight loss with lifestyle change is difficult to maintain Behavioral support may need to be intensified to assist with

weight loss and maintenance Initial weight loss benefits are sustained even with weight

regain Support groups Health care professional teams and community groups should

help patients set realistic goals and encourage adherence to healthy weight loss/maintenance behaviors
