AACE Healthful Eating Recommendations

5

Handelsman Y, et al. Endocr Pract. 2011;17(suppl 2):1-53.

Topic RecommendationGeneral eating habits

Regular meals and snacks; avoid fasting to lose weight Plant-based diet (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

Carbohydrate 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 riceFat 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

Page 6: Glycemic Management in Type 2 Diabetes

AACE Medical Nutritional Therapy Recommendations

• Consistency in day-to-day carbohydrate intake• Adjusting insulin doses to match carbohydrate intake

(eg, use of carbohydrate counting)• Limitation of sucrose-containing or high-glycemic index

foods• Adequate protein intake• “Heart-healthy” diets• Weight management• Exercise• Increased glucose monitoring

6

Handelsman Y, et al. Endocr Pract. 2011;17(suppl 2):1-53.

Page 7: Glycemic Management in Type 2 Diabetes

• ≥150 minutes per week of moderate-intensity exercise – Flexibility and strength

training– Aerobic exercise (eg, brisk

walking)• Start slowly and build up

gradually

• Evaluate for contraindications and/or limitations to increased physical activity before patient begins or intensifies exercise program

• Develop exercise recommendations according to individual goals and limitations

Principles of the AACE/ACE T2DM Algorithm

• Ongoing lifestyle optimization essential– Requires support from full diabetes team

• Set A1C target based on individual patient characteristics and risk– ≤6.5% optimal if it can be achieved safely– Targets may change over time

• FPG and PPG regularly monitored by patient with SMBG

Garber AJ, et al. Endocr Pract. 2013;19:327-336.

Glucose Targets

14

Page 15: Glycemic Management in Type 2 Diabetes

• Choose medications based on individual patient attributes– Minimize risk of hypoglycemia– Minimize risk of weight gain– Combine agents with

complimentary mechanisms of action for optimal glycemic control

• Prioritize safety and efficacy over medication cost– Medication cost small portion of

total cost of diabetes– Risk of adverse effects

considered part of “cost” of medication

• Evaluate treatment efficacy every 3 months– A1C, FPG, and PPG data– Hypoglycemia– Other adverse events (weight

gain; fluid retention; hepatic, renal, or cardiac disease)

– Comorbidities and complications

– Concomitant drugs– Psychosocial factors affecting

patient care

Common Principles in AACE/ACE and ADA/EASD T2DM Treatment Algorithms

• Individualize glycemic goals based on patient characteristics• Promptly intensify antihyperglycemic therapy to maintain

blood glucose at individual targets– Combination therapy necessary for most patients– Base choice of agent(s) on individual patient medical history,

behaviors and risk factors, ethno-cultural background, and environment

• Insulin eventually necessary for many patients• SMBG vital for day-to-day management of blood sugar

– All patients using insulin– Many patients not using insulin

Page 26: Glycemic Management in Type 2 Diabetes

Noninsulin Users• Introduce at diagnosis• Personalize frequency of

testing• Use SMBG results to inform

decisions about whether to target FPG or PPG for any individual patient

Insulin Users• All patients using insulin should

test glucose– ≥2 times daily– Before any injection of insulin

• More frequent SMBG (after meals or in the middle of the night) may be required– Frequent hypoglycemia– Not at A1C target

Blood Glucose Level

Classification Typical Signs and Symptoms Treatment

~50-60 Mild hypoglycemia Neurogenic: palpitations, tremor, hunger, sweating, anxiety, paresthesia

Neuroglycopenic: behavioral changes, emotional lability, difficulty thinking, confusion

Consume glucose-containing foods (fruit juice, soft drink, crackers, milk, glucose tablets); avoid foods also containing fat

Repeat glucose intake if SMBG result remains low after 15 minutes

Consume meal or snack after SMBG has returned to normal to avoid recurrence

<50 Moderate hypoglycemia

Severe hypoglycemia

Severe confusion, unconsciousness, seizure, coma, death

Requires help from another individual

Glucagon injection, delivered by family member or other close associate

Victim should be taken to hospital for evaluation and treatment after any severe episode 

36

Page 37: Glycemic Management in Type 2 Diabetes

Elements of Hypoglycemia Prevention

Set appropriate glycemic targets for individual patients

More stringent goals: young, newly diagnosed, no comorbidities, no micro- or macrovascular disease, strong and effective self-care skills

Less stringent goals: older, limited life expectancy, history of hypoglycemia, longer disease duration, established comorbidities, established vascular disease, limited self-care skills

Educate patients

Signs and symptoms of hypoglycemia Dietary education for improved glycemic control and appreciation of triggers for

hypoglycemia Avoiding missed or delayed meals Appropriate self-treatment Understanding of hypoglycemia unawareness Importance of reporting hypoglycemia

Use self-monitoring of blood glucose

Patient education: technique and action Observation of patient’s procedure and reaction Patient access to providers for purposes of reporting results and for providing guidance Provider reaction to results increases effectiveness of SMBG

Hold a high index of suspicion for hypoglycemia

Understand patients may not report “typical” symptoms When hypoglycemia is suspected, adjust therapy Consider use of continuous glucose monitoring to detect unrecognized hypoglycemia

Choose appropriate therapy

Use agents with a low risk of hypoglycemia Be aware of additive effects of combination therapies on hypoglycemia risk Recognize that long-term costs of hypoglycemia may offset the cost of using older, less

physiologic medications37

Antidiabetic Agents and Weight

• 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
