52 year old engineer with a recent diagnosis of type 2 diabetes

• The patient is referred to you for recent diagnosis of Diabetes

• The patient has a BMI of 37

• He has never really cared about his weight before but when his HCP said that if he lost weight he might not need medications

• “I can do this myself I don’t need medications”

Page 3: Sharp Diabetes symposium 2019€¦ · •Genetics for low fat diet did not lose more weight on a low fat diet ... Patients eat a relatively healthy diet but on alternate days or a

Treatment options to lose 7% -10% • Diet, Exercise and Lifestyle modification

• Diet, exercise, Lifestyle modification and weight loss medications

• Bariatric surgery • Sleeve Gastrectomy

• Gastric Bypass

• What are the odds that the above treatment options can accomplish 7% -10% weight loss ?

• Diet, Exercise and Lifestyle = 20%

• Lifestyle with weight loss medications = 60%

• Bariatric surgery = 85%

What do the Guidelines say about a weight loss Diet

• Any one of the following methods can be used to reduce food and calorie intake:

• 1. Prescribe 1200–1500 kcal/d for women and 1500–1800 kcal/d for men

• Prescribe a 500-kcal/d or 750-kcal/d energy deficit

• 2. Prescribe one of the evidence-based diets that restricts certain food types

• (such as high-carbohydrate foods, low- fiber foods, or high-fat foods) in order to create an energy deficit by reduced food intake.

• 2013 AHA/ACC/TOS Guideline

The 50 year old engineer with new onset DM2

• The patient has been consulting Dr. Google: he has looked at everything he can find on the internet

• He is aware that he is seriously overweight and understands that losing weight is a very good idea

• On his own he has sent off his saliva for genetic testing to find out what is the “perfect diet” for him

• He brings in his “genetic results” it says he should do a low fat diet, he is does not like this idea as his friends are doing a “keto diet”

• What do you tell him ?

Effects of Low-fat vs Low Carb diet on 12 month wt. loss and the association of Genotype pattern and insulin secretion

• 609 overweight or obese non-diabetics patients

• 12 month long study

• Randomized patients to a “healthy low fat” or ”healthy low carb”

• Patients also had their genetics looked at (genotype) and had insulin measured 30 mins after a glucose load

• 40% of the patients had a low-fat genotype

• 30% of the patients had a low-carb genotype

• Gardner CD, Trepanowski JF, Del Gobbo LC, et al. JAMA. 2018;319(7):667-679

Insulin Study (insulin resistance)

• Patients did a 75 gram glucose challenge and the 30 minute insulin was used to separate high insulin producers from low insulin producers

• Average BMI of 33• Average fasting blood sugar 98.5 mg/dl • About a third had metabolic syndrome

Diet: low fat vs low carb

Carbs Fat Protein

Low Fat 48% 29% 21%

Low Carb 30% 45% 23%

Low fat diet: 205 to 212 grams of carbs

Low Carb diet: 96 to 132 grams of carbs

Diet based on genotype and insulin secretion

• Healthy low fat diet patients lost 5.3 kilos

• Healthy low carb diet patients lost 6.0 kilos

• Based on Genotype

• Genetics for low fat diet did not lose more weight on a low fat diet

• Genetics for low carb diet did not lose more weight on a low carb diet

• Based on insulin response no increase is weight loss • High insulin secretors (insulin resistant patients) did not lose more weight

on the low carb diet

• Low insulin secretors (insulin sensitive patients) did not lose more weight on a low fat diet

• Conclusion: using genetics and measuring insulin may not be helpful in predicting the best diet

New diets that have some interesting scientific data

Intermittent or Alternate day fasting (ADF)

Patients eat a relatively healthy diet but on alternate days or a few days a week they take in 25% of their caloric needsTypical needs 2200 kcals per day

25% would be 550 kcals per day

Time restricted eating:The patient eats between 12pm and 8pm (16 hours fasting) 16/8the patient only eats between 4pm and 8pm (20 hours fasting) 20/4The patient skips breakfast and possibly lunch

Page 11: Sharp Diabetes symposium 2019€¦ · •Genetics for low fat diet did not lose more weight on a low fat diet ... Patients eat a relatively healthy diet but on alternate days or a

Does that mean you can skip breakfast?

• Randomized controlled studies actually do not say that we all need to eat breakfast

• A lot of observational studies say “breakfast” is the most important meal of the day

• Randomized 24 overweight pts to having breakfast or not having breakfast

• Then measured their food intake after having breakfast or skipping breakfast

• In this study they served a typical carbohydrate rich breakfast

• cereal with milk, toast and orange juice

Skipping Breakfast

Skipping breakfast did not significantly affect the size of lunch or dinner later that day

Subjects did not report increased hunger skipping breakfast later in the day

The group that skipped breakfast ended up eating 400-450 kcal less that day

Skipping breakfast reduces energy intake and physical activity in healthy women who are habitual breakfast eaters: A randomized crossover trial

• Randomized 20 healthy Japanese women to

• Skipping Breakfast

• Eating Breakfast

• Patients skipping breakfast

• Ate 131 more calories at lunch

• Total energy intake over the day (24 hours) was less then the breakfast eaters by 262 calories

• Step count and physical activity were the same between the groups

• In the morning mild decrease in activity of 41 kcal but over the course of the day no difference in physical activity between groups

Back to Alternate Day Fasting (ADF)

• Randomized 26 patients to either fasting alternate days (Zero calories) or calorie deficit of 400 calories per day for 8 weeks

• Both groups lost 8 Kilos or about 2 pounds per week for 8 weeks

• The group that did ADF ended up cutting their daily caloric intake by 376 calories per day

• At the end 24 weeks no change in weight regain

Does ADF cause compensatory hunger or Change in satiety hormones

• 59 patients attempted Alternate day fasting for 8 weeks • 25% of caloric needs on fasting days• Patients lost about 4 kilos over 8 weeks • Patients decreased their RMR by 100 Kcal per day

• Hoddy KK, Gibbons C, Kroeger CM Changes in hunger and fullness in relation to gut peptides before and after 8 weeks of alternate day fasting Clin Nutr. (16)00102-3 2016 Mar 30

Change in satiety hormones

Ghrelin went up (increase hunger)where does Ghrelin come from ?

Ghrelin comes from the stomach (Fundus) and increases hunger

PYY went up (increased fullness when pts ate)where does PYY come from ?

PYY comes from the small intestines (L-cells) and signals satiety or fullness after a meal

Subjects overall did not feel more hungry at the end of the study

This shows a lack of compensatory hunger to weight loss ?

Patient may also have had a bit more fullness after eating with ADF

(slightly higher levels of satiety hormones)

Intermittent Fasting (IF) Physiology Time restricted eating

• IF is a variety of eating patterns in which no or few calories are consumed for time periods that can range from 12 hours to several days, on a recurring basis.

• Example fast every other day (alternate day fasting)

• Only eating daily between 4pm and 8 pm

• The goal is to switch from glucose metabolism to fatty acid-derived ketones metabolism

• Anton SD. Et al. Flipping the Metabolic Switch; Obesity (2018) 26, 254-268

Once in this state of burning Fatty acids and ketones (what’s the big advantage) • ketones serve as an energy source for muscle and brain cells during fasting and extended periods of

physical exertion/exercise

• Thus, the primary energy source of energy shifts from glucose to FFA (from adipose tissue) resulting in:

• lipolysis and ketones production

• Helps preserve lean tissue (muscle) ?

• Remember conventional dieting will have lean tissue lose:

• for every 4 pounds a patient loses

• Three pounds will be fat

• One pound will be lean tissue

• The older the patient the more lean tissue lost with weight loss

50 year old patient referred for new Onset DM2

• 50 year old patient that you have seen before

• Work up is simple early DM2 with an A1c of 7.1

• His friends are doing the “Keto diet” they are losing a lots of weight

• He has gotten on the internet and Dr. Google claims:

• It will get him to lose weight

• Improve his memory

• He can start going out again and order hamburgers “protein style”

• Hell be in the “ZONE”

• What do you say ? Is this a good idea or bad idea ?

What is a ”Keto Diet”

• Very low carb diet

• How many grams of carbs per day does one need to stay out of Ketosis

• 50-55 grams per day

• The idea is to put a patient into Ketosis

• A diet high in protein and usually high in fat

• Example:

• Breakfast is coffee with butter, eggs, and bacon

• Lunch is a couple of burgers without the bun loaded with cheese

• Dinner is crab stuffed mushroom with cream cheese and bacon blue cheese devil eggs

• And some Keto drinks between meals

Page 24: Sharp Diabetes symposium 2019€¦ · •Genetics for low fat diet did not lose more weight on a low fat diet ... Patients eat a relatively healthy diet but on alternate days or a

Clinical pearl• If you give a patient a diet prescription and have the patient track their food

intake will they:

• Underestimate their food intake

• Overestimate their food intake

• Or be pretty close

• If they underestimate: how much will they underestimate?

• 37% *

• This is why most diets tell pts to eat less than 20 grams of carbs to get into Ketosis

adolescents. Am J Clin Nutr. 1990; 52:421–425.

Back to our patient that wants to do the Keto diet: Diets that Promote Ketosis

“Keto diet”, a diet high in Saturated fat, protein and very low in carbohydrates

Any diet with fewer than 50 grams of carbohydrates a day will produce ketosis

Intermittent fasting

• Between 12 hours and 36 hours of fasting, patients will go into ketosis

“Keto drinks” drinks that have ketones in them to promote a decrease in hunger

Ketone Drinks Web Ad Claims

“Boost ketone levels”

Get back into ketosis

“Benefits”

• Support higher energy

• Support a healthy metabolism

• Supports mental clarity

Patient with Insulin Induced Weight Gaino 56 year old female with 35 pound weight gain since starting insulin for type 2 diabetes.

o She was reasonably well-controlled on metformin and a DPP4 inhibitor for about 5 years, but about 2 years ago her A1c jumped from 7.8 to 10.4%. She had a sulfonylurea added but the best her A1c got to was 9.8. She tells you she did not like being on the sulfonylurea because she started gaining weight.

o She had her oral meds stopped and her HCP started basal insulin and titrated it up to 75 units a day. Her A1c improved to 8.0% and HCP was sending the patient to you at the patient’s request.

o The patient states she is having “low blood sugars” in the late morning, early evening, and if she does not eat something before going to bed she will get low blood sugars in the middle of the night. Her sleep has been poor and she feels tired. She checks her blood sugar sporadically and was a little vague on actual blood sugar values.

o She normally weighs about 135 pounds at a height of 5 feet tall. She is close to 170 pounds.

IIWG: Physical Exam and Other Infoo The patient appears to be very down when she tells you about the weight gain

o She tells you that she has always had a “tummy” but she has gained so much weight that buying clothes is becoming difficult. Her eyes well up with tears when she tells you her 7-year old granddaughter asked her if she was pregnant.

oOn exam, she has classic central adiposity.

oOropharynx shows a very crowded upper airway

o She has neuropathy of the feet up to her ankles (and is on gabapentin 300 mg TID).

o The rest of the exam is unremarkable.

Factors Associated with Insulin-Induced Weight Gain (IIWG)

The more insulin you give the more the patient is susceptible to weight gain Anything close to or higher than 0.5 units of Insulin per kg

Adding short acting (bolus insulin)

Starting at a lower BMI (less than 30)

Average weight gain is 10 to 20 pounds the first year

Insulin is an anabolic hormone• Inhibits protein catabolism• Inhibits lipolysis• Promotes lipogenesis = central obesity => Insulin resistance

Increase in caloric intake• Defensive eating (perceived fear of hypoglycemia) • DCCT patients who experienced severe hypoglycemia had more weight gain vs patients who did not • Increase appetite is an early, adaptive response to low blood sugar levels

How to Approach Insulin-Induced Weight Gain

• ASK the patient if it is OK to bring up the issue of weight gain

• EDUCATE the patient that this is a known side effect of insulin

• Look for other potential causes of weight gain• 2 potential causes in this case

• Medication induced weight gain with gabapentin

• Sleep apnea

• Let the patient know there are treatment options

Start Metformin1. inexpensive

2. improves insulin sensitivity

3. less insulin will be required (29% less insulin)

4. the etiology of metformin’s effect on weight loss is not known but is most likely metabolic and not a decrease in food intake

• No change in food intake noted in a randomized trial

Start a SGLT-2 Inhibitor?Upside:

• Lose ~300 calories per day in the urine• Lose 2-3% of weight (more if combined with appetite suppression) • Improved A1c

Downside:• Potential for Ketoacidosis

• Typically have to decrease insulin when starting an SGLT-2 inhibitor and may not have enough insulin to suppress lipolysis and ketosis

• SGLT-2 inhibitors promote glucagon secretion• Possible decrease in excretion of ketones by the kidneys (decreased renal

clearance of ketones) • Particularly dangerous if the patient is doing a Keto diet or intermittent

fasting with the SGLT-2 inhibitor • Probably safe in patients that have never required insulin and are well

controlled

Factors to Consider When Choosing a Medication for Weight Loss

Out of pocket COST or is it reimbursed by insurance• GLP-1s and SGLT-2 inhibitors are often covered for patients with diabetes

o often regardless of A1c %• Typically weight loss medications are not covered

o In many areas of the U.S. over 30% of the weight loss meds are coveredo Several medications have cash discount cards

Patient preference • Is the patient willing to use an injectable medication• Approximately 60% of patients want to consider a weight loss medication *

o 55% of geriatric patients, and 65% of younger patients want to consider a weight loss medication treatment

Prescribing clinician comfort with prescribing • Is the prescribing clinician comfortable using injectable medications• Is the prescribing clinician comfortable using weight loss medications

• Is it safe for a patient with Diabetes

Cardiovascular Safety of Lorcaserin in Obesity NEJM E.A. Bohula, S.D. Wiviott, D.K. McGuire et. Al. August 2018

Randomize 12,000 patients with Cardiovascular disease (75%) and/or Diabetes (57%) with multiple cardiovascular risk factors

Randomized half the patients to lorcaserin and half to placebo

Primary outcome: cardiovascular event • (example stroke, myocardial infarction, heart failure, angina etc.)

Cardiovascular Safety of Lorcaserin in Obesity NEJM E.A. Bohula, S.D. Wiviott, D.K. McGuire et. Al. August 2018

At the end of 36 months

• 12.8% of patients in the Lorcaserin group had a Cardiovascular event

• 13.3% of patients in the Placebo group had a Cardiovascular event

Lorcaserin group lost more weight (4.2 kg vs 1.4 kg) at one year• This was a safety trial not a weight loss study

Adverse events: 13 Lorcaserin patients vs 4 placebo patients had serious hypoglycemia

Effect of Lorcaserin on Prevention and Remission of Type 2 Diabetes

Erin A Bohula*, Benjamin M Scirica*, Silvio E Inzucchi, et.al. www.thelancet.com October 4, 2018

Of the 12,000 patients • 56.8% had diabetes• 33.3% had prediabetics

• 9.9% had normal glycemic

Decreased incidence of patients converting from pre diabetes to diabetes

Patients with diabetes saw improved blood sugar control

Reduced risk of microvascular complications

Patients with diabetes lost more weight as the trial progressed

Bottom Line

For the high risk cardiovascular patient• Lorcaserin = safe• Liraglutide = safe

At this point in time • Naltrexone/Bupropion not recommended• Phentermine/topiramate not recommended

Look AHEAD Instructions on Reduction in Insulin Before Starting Weight loss

• Asked patients to check blood sugars twice daily for one week

• ≥ 2 blood sugars < 100 mg/dL

Reduce insulin 0% to 50%

• ≥ 3 blood sugars 80 to 100 mg/dL

Reduce insulin 25% to 75%

• ≥3 blood sugars < 80 mg/dL or severe hypoglycemia, or symptomatic hypoglycemia > 2

• Reduce insulin by 50% to 100%

• Average decrease in insulin was 50% by year one in the Look AHEAD trial

• Look AHEAD Research Group. J Diabetes Complications. 2016 Jul; 30(5): 935–943

Summary: Weight loss in the Patient with Diabetes

• Weight loss from SGLT-2 inhibitors is limited by metabolic adaptation• Be prepared to add either an appetite suppressant or GLP-1 agonist

• Weight loss medications have come a long way in terms of safety • Two of the currently chronic weight loss medications have completed Cardio Vascular Outcome Trials • These cardiovascular outcome trials have included large numbers of high risk pts with Diabetes

• Patients that start insulin are at high risk for gaining central adiposity

• Look for other causes of weight gain besides the insulin

• Metformin and GLP-1s are extremely helpful for weight management in patients on Insulin

• SGLT-2 inhibitors can be very helpful in pts on insulin but need to be used with caution

• Lifestyle modification and Weightloss medications can be used in patients on Insulin but start insulin modifications early
