soaps on telly and people talking about the characters as if they were real.
I started to wonder what evolutionary advantage T2 diabetes might have. ( like sickle cell protects from malaria!)
I think I may have got somewhere.
Metabolic syndrome, causes the body to accumulate fat. A very valuable trait in times of famine.
This would back up my notion that metabolic syndrome is the cause of obesity, not its consequence.
Could it be the original "Thrifty gene", which has been speculated on?
When 2 conditions are obviously linked, as in obesity and diabetes T2, it's sometimes difficult to disentangle cause and effect. If I'm right, only in times of a glut of food, would the T2 genes become a problem. This would also exlain why many T2s are slim and many obese people don't develop T2. As well as why it's getting more frequent and why populations, who are used to food poverty, throw up a lot of T1s when their food availablity increases.
T1 is probably the result of infection and there is even an idea of which virus causes it.
 
It makes sense to me that thrify genes help us to maximise the feast so that we have reserves to see us through the famine.

However, in many parts of the world we live in a state of permanent feast, especially with all the grains grown by modern agriculture, without the need for that hard physical work and they soon become a positive evolutionary disadvantage.
