Transcript on Health Talk: Obesity is Risky
« on: April 23, 2007, 10:19:54 am »
Last Friday, April 20 I attended a Health Talk by Dr Romulo De Villa, who is a Molecular and Nutritional Oncologist. And here is the transcript I have made. Us medical professionals can't resist taking down notes and I present my notes for everyone's benefit.

Health Talk: Obesity is Risky
Dr Romulo De Villa

Not all obese people are created equal
8/10 obese individuals are at greater risk of:
1.   diabetes
2.   high blood pressure
3.   high cholesterol levels
4.   death from cardiovascular disease (heart attack)
5.   cancer (colon cancer)

Mortality Trend: Rate per 100,000 population
1.   Communicable (infectious disease)  Downward since 1950
2.   Heart Disease  Upward
3.   Cancer  Upward
Epidemiological shift from infectious disease to cardiovascular disease and cancer
1.   Increased pollution that has gotten in our food
-- a little fact: inhaling fumes that comes from frying food can cause cancer!
2.   Overweight and obesity

Health is at risk if BMI is equal to or greater than 25kg/m2 (Asia-Pacific uidelines)
   How to Compute: divide your weight in kilograms by the square of your height

How to Evaluate Your BMI
1.   Not accurate because weight of fat and muscle
a.   Someone may have a BMI that is in the unhealthy range but is a body builder, can still be healthy and not at risk
2.   Someone with very little muscle mass (elderly) may be at normal range but ay risk
3.   If you are a body builder, under 5 feet tall, or elderly, have a fat mass analysis to more accurately assess fat content of the body
4.   If your BMI is greater than of equal to 30, you are at a greater risk for heart disease if ratio of triglycerides to total cholesterol in your blood is 3.5 and above.

How to Determine Risk of CVD
1.   Determine the amount of Visceral Abdominal fat (the fat within the walls of the abdominal muscles, not the fat under the skin that you can pinch)
a.   Abdominal CT scan (accurate)  the cut off point for healthy amount is less than 100 sq. cm for Japanese and 130 for Canadians. Use the Japanese as a reference for Asians.
2.   By measuring Waist Circumference at the navel (estimate)
a.   Waist circumference particularly useful for individuals with a BMI of 25-34.9. For individuals with a BMI of greater than 35, waist circumference adds little productive power on the disease due to risk classification of BMI
b.   For Women
i.   Increased risk if 35 inches waist circumference
ii.   Greater risk if with BMI 25+
c.   For Men
i.   Increased risk if 40+ inches
ii.   Greater Risk if with BMI 25+

How to Reduce Risk
   Lose weight!
-- eat more fruits and vegetables
-- avoid pork and fried food
-- eat more carbohydrates when you wake up than before you are about to sleep (better if as little cabs as possible before sleeping)
-- do not skip breakfast (the body will conserve more calories if you do this)
-- do more physical activity
-- may take weight loss supplements (TRA, Trimshake, Metabotrim, Tegreen)
-- use Trimshake as a meal replacement

      -- delicious and satisfying drink
      -- perfect as meal replacement for lunch and dinner
      -- high in protein (20g) and soluble fiber (3g)
      -- low fat (35g)
      -- perfectly balanced with carbohydrates (26g)
      -- available in chocolate and vanilla flavors

When fat attacks you, you first get metabolic syndrome
   Learn to defeat the attacks by knowing how to do it

Fat cells behave differently in different parts of the body
   -- subcutaneous (under the skin) fat  benign (hips and thighs) because it’s less metabolically active thank the kind that accumulates around the organs in the abdomen
   -- visceral fat
      -- highest association with diabetes, high blood pressure, high triglycerides
      -- more inflammatory and clot forming
      -- fortunately, visceral fat is also first to disappear
Intra-abdominal fat (visceral) – the dangerous adipose (fat) tissue

Fat tissue – an organ? (endocrine)
   -- communicates with other organs and tissues though chemical signals passing through bloodstream

Biochemical Mechanisms working I fat cells
   -- chemical messengers
      -- thrombotic (pro-clotting)
      -- vasoconstrictors (increase blood pressure)
      -- anti-inflammatory and inflammatory agents
         -- cholesterol levels is not the key, it’s the inflammation!
   Fat tissue
      -- attracts immune-system cells called macrophages
      -- promotes inflammation
   Inflammation – key mechanism in heart disease
   Chronic inflammation – fight with anti-oxidants

Attack and Destroy
   -- when you don’t step he attack, it leads to destruction (degenerative disease)
   -- heart disease, stroke

How to stop? Lose weight! (see above)

The Right Approach
1. Right weight loss products
2. Right nutrition
3. Right exercise

I have included here images from a website Dr De Villa recommends as a guide to health.

Guys, all the money in the world is dust if you are with a debilitating disease like heart attack or stroke. So better take care of yourselves now. I hope my notes are of benefit to you.
