OutlineBackground

• Define the Molten Moment• Obesity as a Growing Concern• Define Obesity in Children

1) Story of Fat Cell • Not too Big = Metabolic Synd• Not too small = Hunger• But Just Right

2) Many interventions reduce Metabolic Risk & CVD

3) Only interventions performed at the MOLTEN MOMENT can “cure” obesity forever.

The Molten Moment

A Cold Iron, Solid A HOT Iron, Malleable

DEFINITION of Mol-ten: liquefied by heat; having warmth and brilliance, glowing

Since 1980, Childhood Obesity

rates have tripled

Prevalence Rates of Childhood Obesity

Obesity=Bad

If rising OW/OB trends continue, by 2030 it will reach 16-18% of total health-care costs in the United States. (Wang, Beydoun, Liang, Caballero, Kumanyika, 2008)

Obesity is a Growing problem

Atherosclerosis

Currently, the world’s leading causes of death are the Atherosclerosis-related dz:

1. Ischemic heart disease (IHD)2. Stroke (Lopez &Mathers, 2006; Mathers et al., 2009).

Part 2: The Big 5

The 5 Behaviors that protect your fat cells

Eat Five Times a Day

Recommendations: Do not skip Breakfast(Skipping Meals in General)= BMI

Eat 5x a day (3 meals, 2 snacks)Eat Family Meals at Home 5x a week

Television

Recommendations:1) Watch TV ≤ 2 hrs/day2) Those under age 2 should not watch TV3) Remove TV from where children sleep

Physical Activity

Recommendations:1 hour of physical

activity or active play accumulated

throughout the day.

Sweetened Beverages

Sweetened Beverages

Each Serving of Sugar-Sweetened Beverages per day is associated with an increase in BMI (Forshee, Anderson,Storey, 2008) Meta-analysis

Recommendations: No zero zilch sweetened beveragesand ≤ 4 oz of 100% Fruit Juice per day

Half a Plate

7 “ plate for children

How to Assess

1: What do you do after school?

Do you live in a safe neighborhood?

2: How often is the TV on?

What are your favorite shows?

Is there a TV in the bedroom?

0: What do you drink?

1/2: Is half of everything you eat a fruit

or a vegetable?

5: Describe what you eat on a regular day?

Questionnaires like REAP & WAVE

Part 2: The Big 5

SUMMARY:

You can’t kill a fat cellAfter 8 is too late.

5, 2, 1, 0… And half a plate.
