Unique Challenges forWomen with PCOS
Yo-yo dieters
Intense cravings
Hypoglycemia common
Hormonal aberrations
Dermatological concerns
Higher prevalence of eating disorders
Impaired levels of ghrelin & leptin
Increased anxiety, depression, bipolar, suicide
What is the best dietcomposition ?
Low-Fat Diets
exaggerate postprandial glycemia
increase TG, decrease HDLconcentrations
promote higher consumption of refinedcarbohydrates
Makes MBS worse
contribute to hunger, overeating, andweight gain

Low vs. High Protein Diets
28 overweight or obese PCOS women
High protein (40% CHO, 30% Pro, 30% Fat) vs.Low Protein (55% CHO, 15% PRO, 30% Fat)
Both diets 1400 calories for 3 months
Weekly nutrition classes; exercise 3x/wk
Results: No significant difference was found!
Both groups lost weight, improved insulin,testosterone, menstrual function and other labs.

Very Low-Calorie Diets
114 obese women with PCOS
500 calories/day for 4 weeks
1,000 calories/day for 7 months
Results: 54% lost > 5% of body weight,11.8% remained at pretreatment weight;both groups showed improvements intestosterone levels.

ages 18-35 Measured insulin levels

What is the best dietcomposition ???
For Reducing Insulin & Weight:
Lower intake of carbohydrates
Almost all whole grain, high fiber Avoidance of sweetened beverages
Spread evenly throughout the day
Eat frequently (every 3-5 hours)
Protein matching at all meals and snacks
Rich intake omega-3s
For Heart Health
Daily fat intake 35-45% of total daily calories
No more than 7% saturated fat. Transfatsshould be eliminated
Up to 20% of daily calories frommonounsaturated fatty acids, and up to 10%polyunsaturated fatty acids
Consume fatty fish 2x/week
Fish oil supplement
Plant sterols
Red wine
Protein
Lean, protein-rich foods with all meals andsnacks
Experimenting for optimal foodcombinations
Benefits of Protein
Delays postprandial response
Decreases hunger
Increases satiety Decreases ghrelin
Increases Thermic Effect of Food
Preserves LBM
Protein Intake & Fertility
Nurses Health Study-18,000 nurses Highest-protein group had 41% more ovulatory
infertility.
Women with the highest intake of animal proteinhad 39% more ovulatory infertility than thosewith the lowest.
Those who consumed the most plant-basedproteins had the lowest amount of infertility. exceptions were for eggs, dairy, and fish which were
found to increase fertility.

Supplements WithInsulin-Sensitizing Properties

Vitamin D3 Omega-3 fatty acids
Role of Exercise
3-month exercise program vs. hypocaloric diet
19 sedentary women with PCOS
SET: 25% improvement of insulin sensitivity
without weight loss.
improved fertility and menstrual cyclicity thanthose who followed a hypocaloric diet.
SET group also had greater improvements inwaist circumference and insulin resistance
despite only a smaller reduction in weight.
Barriers to Physical Activity
Size
Muscular shape
Its exercise!
The Role of The Dietitian inTreating PCOS
Empathetic, supportive, encouraging approach
Provide education on PCOS and insulinresistance
Education on healthy diet and exercise
Encourage a healthy approach to eating andexercise rather than focusing on weight loss
Assess symptom severity (including eatingdisorder behaviors)
Assess medication compliance
The Importance of NutritionCounseling for PCOS
In a study on the effects of exercise andnutritional counseling in women withPCOS, Bruner et al (2006) found thatnutritional counseling, with or withoutexercise, decreased insulin levels andimproved both metabolic and reproductiveabnormalities associated with PCOS.
The Nutrition Assessment
Screen any woman for PCOS Provide appropriate referral information
Screen for distorted eating
Review lab results Assess diet
Educate patient and parents about PCOS Insulin resistance Connection to symptoms Long-term risks Role of diet and exercise
Assess readiness for change

Tell me what your periods are like. Are they heavy,irregular, absent, etc.?
What types of foods do you crave and when do you
crave them? Do you ever feel lightheaded, dizzy, nauseous, orirritability that gets better when you eat?
Have you ever been told by your physician or healthcareprovider that you have any abnormal lab values?
Can you tell me about any excessive body hair thatyouve dealt with?
Do you have dry/rough elbows, skin tags, or any darkpatches that look dirty on your body?
Does anyone in your family have polycystic ovarysyndrome?

Questions to ask a patientsuspected of PCOS: Tools
Food records
Mindful eating exercises
Food models and labels
Handouts
How food affects insulinlevels
Food exchanges
Managing hypoglycemia
Scale vs. waistcircumference
Lab results
PCOS in Pregnancy
Higher risk for:
Gestational diabetes
-GDM ~ 3.5% in general population
-GDM in PCOS estimated to be 20-50%
-Early OGTT
Miscarriage
Neonatal intensive care stays
Other Concerns in Pregnancy
Multiple babies
Food fears
Emotional Concerns
Weight gain
Body image issues
PCOS & Pregnancy
Should be considered a state of GDM:
-Moderate intake of carbohydrates
-Even distribution of carbohydrates-Protein matching
Daily exercise, preferably after meals
Patient education of risks
Appropriate weight gain
Metformin in Pregnancy
10-fold reduction inGDM using metformin

Unique Concerns:PCOS & Lactation
Insufficient milk
production
Failure of breast
tissue to develop
Insulin resistance
Adherence due to
size
Overabundance of
milk production
Guidelines To Establish AdequateMilk Supply in PCOS:
Pump after feedings for 10-15 minutes on
each breast in the first 2 weeks of initiatingnursing
Frequent feedings with full drainage
Adequate diet and fluid intake
Extra breast stimulation by frequentnursing or pumping sessions is crucial
Resources prior to birth
Safety: Metformin & Lactation
61 nursing infants and 50 formula fed infants
born to mothers with PCOS
took an average of 2.55 grams of Metformin per
day throughout pregnancy and lactation
Infants followed birth-6 mo.
Metformin had no adverse health risks in
regards to growth or motor-social development.
Glueck C et al. J Pediatr2006;148:628-32.
PCOS in Adolescence
Adolescence is the most vulnerable and
influential stage of PCOS.
It is in adolescence when symptoms of PCOS
first start to present themselves.
Changes can be made to diet and lifestyle thatcould prevent the worsening of symptoms later
in life and prevent the onset of many health
complications.
Obstacles Affecting Treatment
Proper diagnosis/ Lab profile
Patient readiness
Mental status Anxiety, Depression, Eating disorders
Social involvement
Family involvement
Resistance to exercise
In Summary
PCOS is a very complex, under-treated andunder-recognized epidemic
Early detection and treatment are key
Diet plays an important role in the treatment of
PCOS
RDs can offer lifestyle counseling on weight loss
and diet to improve insulin resistance to reducethe risk of chronic disease within the PCOSpopulation
