ESTABLISH ACTIVITY AS NORMAL PART OF LIFESTYLE
TAKE CARE TO PROVIDE APPROPRIATE SNACKS TO PREVENT PROVIDING POSITIVE CALORIE BALANCE
Understand their growth pattern and stages

BMI charts don’t account for body composition
Don’t account for inherent growth pattern difference in PWS
Can be used for monitoring but interpretation of results is very difficult
Growth charts better
Expectation should be for proportional growth along UK centiles
Specific PWS charts act as good additional reference
Specific PWS charts describe how PWS children grow not how they should grow
Due to nature of body composition BMI on standard charts may be misleading
PHASE 2b -Increased interest in food-Frequent food based questions-Will eat in line of sight
PHASE 2a-No increase in appetite-Appetite for age-Typically needs 60% -Will become obese if typical diet
PHASE 1b-No longer needs assisted feeding-Grows steadily along curve with N intake-Normal appetite
PHASE 1a-Weak suck-Oral feeds very slow-Decreased appetite -Doesn’t cry at feeding times-Weak cry

Importance of a team approach
ROCKET SCIENCE ??
• Your child is invited to a birthday party at McDonalds. Should they go?
• PRO Social, inclusive, exposure inevitable
• CON Exposes child to temptation/ well meaning peers/ represent poor quality food
PLAN AHEAD BE CONSISTENT
• The school class is doing an optional cookery classes. Should your child be involved?
• PRO Great interest, opportunity for education
• CON Breaks structure, adds temptation, well meaning friends teachers
PLAN AHEAD BE CONSISTENT
• Allow treats / seconds on special occasions?
• PRO Part of childhood
• CON Never forgotten, tightrope of calories
PLAN AHEAD BE CONSISTENT
Good guys vs bad guys
Food Security
MISTAKEN BELIEF
This is because efforts to limit food, if attempted without establishing FOOD SECURITY ,cause increased stress in the form of doubts, hope and disappointments
Provide food security
• Structure
• Consistent approach
• Visual menus
• Portion cups
• NO DOUBTS about what will be provided and when
• NO HOPES of obtaining food outside the plan
• NO DISAPPOINTMENTS concerning food
LOCK AWAY TEMPTATIONOR
DON’T HAVE IT
BECOME A NUTRITION EXPERT
What is a normal portion size?
Segmented lunch boxes
Structured, ensures consistent portions
RE THINK HOW YOU THINK ABOUT FOODS
Using food rewards (and withholding them) for behaviors which may be the result of stress or anxiety [e.g. refusals, tantrums, shutdowns] may worsen the situation
NON FOOD TREATS FOR PWS CHILDREN
LOVE MEANS SAYING “NO”
WHAT EXTRA CAN I DO ?Special diets
KETOGENIC DIET
• 108 families express interest
• 14 families completed requirements
• 10 families completed 6 months
Ketogenic diet
• No good quality studies
• Large amount of work needed
• Risks of balancing the diet
CONCLUSION:Despite the burden of managing a structured diet 10 families found it was worthwhile and have continued beyond 9 months.
LOW FIBRE
• Concerns about swallow / food lodging
• 1. Provide small, frequent meals. Avoid the three LARGE meals per day. Break up meals/snacks to three small meals and two snacks a day (six is only recommended if the person has diabetes). Reduce quantity of food being provided at one time.
• 2. Include more liquid or semi-liquid food items. Provide liquids during and between meals. Have person drink water or fluids between bites of food. (Helps moisten food and facilitate movement from mouth to the stomach; less work and time with food in stomach).
• 3. AVOID: RAW vegetables and fruits, nuts and salads. (YES, this is a change)
• 4. DO PROVIDE: vegetables that have been cooked (softened) and/or mashed, fruits in softer form – applesauce, fruits in natural juices, and cooked cerealDont eat too late
WHAT EXTRA CAN I DO ?Supplements
WHAT DOES IT MEAN ?
Very small number of PWS patients, also reduced calories, application to the real world not clear At best encouraging and paves the way for more work but insufficient to recommend to all
• No significant differences in total and free carnitine or CoQ10 levels between individuals with PWS, obese individuals, and sibling control groups.
• 20 families elected to try carnitine supplementation (50 mg/kg/day divided twice a day) regardless of the serum carnitine profile results.
• 13 of these twenty families (65%) reported subjective improvement of exercise tolerance and daytime alertness with carnitine supplementation.
• 7 of the 20 families who tried carnitine supplementation discontinued it due to lack of benefit and/or side effects of therapy.
• 10 families started CoQ10 supplementation (50 mg/day) • 5 (50%) of these families reported benefits in daytime • All of the individuals who were reported to benefit from CoQ10 were under
3 years
Co enzyme Q10
• Deficiency rare
• Associated with increased physical activity, increased muscle tone and strength, increased cognitive ability, less sleeping, increased "energy"
• Deficiency rare
• Associated with improved mental and physical lethargy, muscle weakness and hypotonia in the early presentation of PWS
• No studies in PWS
INSUFFICIENT EVIDENCE PARENT CHOICE
Carnitine
