"A discovery by Queen's biologists and their students sheds new light on the genetic roots of obesity - a condition that is increasing dramatically in North America and has been linked to heart disease, diabetes and some forms of cancer...There is no genetic basis.
Professors William Bendena and Ian Chin-Sang teamed up to work with tiny, transparent worms that have similar neurotransmitters (chemicals that transmit nerve impulses) as humans. They discovered that when a specific nerve receptor is deleted, the worms lose interest in foraging for food, become slow-moving and accumulate fat at a much higher rate than normal, non-modified, worms. "
It is all Calorie-based. No gene, hormone, biologic agent, etc. can result in overweight/obesity in the absence of too many Calories in relative to Calories out.
The only worms of relevance here are the slithering researchers.
