Consequences of Obesity in
Diabetes
• Increases risk of cardiovascular comorbidities
– Hypertension
– Dyslipidemia
– Atherosclerosis
• May limit ability to engage in physical activity
• Increases insulin resistance
– Worsens glucose tolerance
– Necessitates higher exogenous insulin doses
• Changes neuroendocrine signaling and
metabolism
• Reduces quality of life
Goal: 5% to 10% weight loss

AACE Recommendations:
Therapeutic Lifestyle Changes
Parameter
Treatment Goal
Weight loss
(for overweight and
obese patients)
Reduce by 5% to 10%
Physical activity
150 min/week of moderate-intensity exercise (eg, brisk walking)
plus flexibility and strength training
•
•
Diet
•
•
•
•
Eat regular meals and snacks; avoid fasting to lose weight
Consume plant-based diet (high in fiber, low
calories/glycemic index, and high in
phytochemicals/antioxidants)
Understand Nutrition Facts Label information
Incorporate beliefs and culture into discussions
Use mild cooking techniques instead of high-heat cooking
Keep physician-patient discussions informal
Handelsman YH, et al. Endocr Pract. 2015;21(suppl 1):1-87.
20
AACE Recommendations:
Healthful Eating
Carbohydrate
Specify healthful carbohydrates (fresh fruits and vegetables, legumes, whole
grains); target 7-10 servings per day
Preferentially consume lower-glycemic index foods (glycemic index score <55 out
of 100: multigrain bread, pumpernickel bread, whole oats, legumes, apple, lentils,
chickpeas, mango, yams, brown rice)
Fat
Specify healthful fats (low mercury/contaminant-containing nuts, avocado, certain
plant oils, fish)
Limit saturated fats (butter, fatty red meats, tropical plant oils, fast foods) and trans
fat; choose fat-free or low-fat dairy products
Protein
Consume protein in foods with low saturated fats (fish, egg whites, beans); there is
no need to avoid animal protein
Avoid or limit processed meats
Micronutrients
Routine supplementation is not necessary; a healthful eating meal plan can
generally provide sufficient micronutrients
Chromium; vanadium; magnesium; vitamins A, C, and E; and CoQ10 are not
recommended for glycemic control
Vitamin supplements should be recommended to patients at risk of insufficiency or
deficiency
Handelsman YH, et al. Endocr Pract. 2015;21(suppl 1):1-87.
21
AACE Physical Activity
Recommendations
• Evaluate for contraindications • ≥150 minutes per week of
and/or limitations to increased
moderate-intensity exercise
physical activity before patient
– Flexibility and strength training
begins or intensifies exercise
– Aerobic exercise (eg, brisk
program
walking)
• Develop exercise
• Start slowly and build up
recommendations according to
gradually
individual goals and limitations
Handelsman YH, et al. Endocr Pract. 2015;21(suppl 1):1-87.

Risk of additional weight gain must be balanced against the benefits of the agent
– Sulfonylureas may negate weight loss benefits of GLP-1 receptor agonists
or metformin
– Insulin should not be withheld because of the risk of weight gain

Dyslipidemia Summary
• Patients with diabetes and insulin resistance
syndrome have atherogenic dyslipidemia and
an increased risk for CVD
• Although statin therapy is effective in lowering
LDL-C, residual CVD risk remains after statin
therapy
• To reduce residual CVD risk, lipid
abnormalities beyond LDL-C (non–HDL-C,
triglycerides, HDL-C) should be intensively
treated
CVD, cardiovascular disease; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol.

Hypertension Summary
• In T2D, blood pressure lowering has the greatest and most
immediate effect on morbidity and morality
• The recommended BP target for patients with diabetes is
~130/80 mmHg
• Multiple agents are usually required to achieve target BP
• BP treatment must be continued for benefits to be maintained
• An ACE inhibitor or ARB should be included in the BP-control
regimens of patients with diabetes because of beneficial effects
on the renin-angiotensin system

• Annual assessments
– Serum creatinine to determine eGFR
– Urine AER
• Begin annual screening
– 5 years after diagnosis of T1D if diagnosed before
age 30 years
– At diagnosis of T2D or T1D in patients diagnosed
after age 30 years
AER, albumin excretion rate; eGFR, estimated glomerular filtration rate; T1D, type 1 diabetes; T2D, type 2 diabetes.

– Optimal glucose, blood pressure, and lipid control
• Use low-dose aspirin for secondary prevention of CV
events in patients with existing CVD
– May consider low-dose aspirin for primary prevention of CV
events in patients with 10-year CV risk >10%
• Measure coronary artery calcification or use coronary
imaging to determine whether glucose, lipid, or blood

–
–
–
–
•
Gross noncompliance with medical regimen
Depression with the possibility of self-harm
Debilitating anxiety (alone or with depression)
Eating disorder
Cognitive functioning that significantly impairs judgment

Diabetes and Cancer Risk
Management
• Conduct cancer screenings as recommended for age
and sex
• Encourage healthful diet, physical activity, and weight
management
• Evidence is inconclusive on effects of specific drugs
on cancer risk due to limited data and confounding
factors
• Cancer risk should not be a major factor in the choice
of antidiabetic agent unless the patient has a very
high risk of cancer occurrence or recurrence

Diabetes and Cancer: Summary
•
Screen obese individuals with diabetes more frequently and rigorously
for certain cancers
– Endometrial, breast, hepatic, bladder, pancreatic, colorectal cancers
•
Increased BMI (≥25 kg/m2) also increases risk of some cancers
– Strong associations: endometrial, gall bladder, esophageal , renal, thyroid,
ovarian, breast, and colorectal cancer
– Weaker associations: leukemia, malignant and multiple melanoma,
pancreatic cancer, non-Hodgkin lymphoma
•
To date, no definitive relationship has been established between
specific hyperglycemic agents and increased risk of cancer or cancerrelated mortality
– Consider avoiding medications considered disadvantageous to specific
cancers in individuals at risk for or with a history of that cancer
