By the way, obesity is not caused genetically as some maintain. Neither is it a disease (although some medical conditions cause weight gain)... Obesity is caused by self-indulgence--by eating too much food or by eating the wrong food.
Bogus Claim A: Obesity is not genetic.
First of all, 80% of children whose parents were both obese become obese. That alone should tell you that obesity is genetic. More improtantly, some of the genes that affect obesity rates have been identified.
- FTO Gene: The FTO gene is associated with the orexin peptide responsible for controlling appetite.
- NPC1 gene: The NPC1 gene regulates the transport of cholesterol between cells.
Similarly the following loci have also been discovered which are responsible for the following conditions which play a role in obesity:
- 2p23.3: Proopiomelanocortin deficiency
- 18q22: Melanocortin-4 receptor polymorphism
- 5q15-q21: Prohormone convertase-1 deficiency
- 7q31.3: Leptin deficiency
- 1p31: Leptin receptor deficiency
To list every gene discovered to play a role in BMI would take too much room on this blog as I barely scratched the surface on what has been found. Regardless of the number of identified genes regulating obesity, the claim that obesity isn't genetic has been totally debunked.
Bogus Claim B: Obesity isn't a disease.
In developed nations, obesity is considered a disease; although 3rd world nations may consider obesity a sign of wealth and opulence. Regardless, obesity is a medical condition since it affects the health of patient. Ray even agrees that obesity has been linked to health problems, so I don't understand this statement at all.
Bogus Claim C: Obesity is only caused by people eating too much.
While I won't disagree that a bad diet and lack of exercise can exacerbate obesity, here's a fact that blows Ray's claim out of the water:
Most overweight people are actually eating less than slender people. That does not seem to make sense, but it is true. The problem lies with how the body is able to burn or utilize the calories from the foods we eat. Thinner people simply burn off more calories, or energy, than heavy people do.
That's right, obese people usually eat less than thin people. I don't need to say any more.
Ray Comfort, you've just been debunked again.
