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
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.
• ≥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
• 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

Glycemic Management in Type 2 Diabetes
Technology for Type 2 Diabetes Management
25
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
SMBG in Type 2 Diabetes: AACE/ACE Recommendations
26
Testing positively affects glycemia in T2DM when the results are used to:• Modify behavior• Modify pharmacologic treatment

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
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

Safety Concerns: Weight
41
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

Glycemic Management During Religious/Cultural Fasting
48
Al-Arouj M, et al. Diabetes Care. 2005;28:2305-2311.
• Frequent glucose monitoring—break fast immediately if patient has: – Hypoglycemia
• SMBG <70 mg/dL while taking insulin or sulfonylureas• SMBG <60 mg/dL while on other therapies
– Hyperglycemia: >300 mg/dL• Healthful eating before and after each fasting period
– Complex carbohydrates prior to fast– Avoid ingesting high-carbohydrate, high-fat foods when breaking fast
• Avoid excessive physical activity but maintain normal exercise routines
• Avoid fasting while ill
