Factors Affecting Metabolism In Order Of Greatest Impact To Least:
Muscle tissue
Meal frequency (the longer you go between meals the more your metabolism slows down to conserve energy)
Activity level
Food choices (ex. low-fat diets tend to result in poor hormone production which leads to a slower metabolism)
Hydration (over 70% of bodily functions take place in water – not enough water causes all your systems to slow down and unnecessary stress)
Genetics (I personally think this is bollocks)
Hormone production and function (think you have a slow thyroid? it’s not likely – before you go blame it on the thyroid first stabilize your blood sugar and throw in some progressive exercise 2-3 times each week)
Stress (stress also can slow metabolism by placing extra stress and strain on numerous systems. plus, many people tend to overeat when “stressed out”)

It seems that quite a few people do think there is a link between genes and obesity. Admittedly most of the experimental work has been done on rodents but they are mammals and not that dissimilar to humans for gene and hormone functions.

They also ate 30% less food, but remained healthy and active.

Having said that I am markedly unsympathetic to the fat gits in society. Exercise more and eat less. However it is all symptomatic of an increasing tendency to refuse to accept responsibility for one's own actions and to expect other people to pick up the tab when something forseeable and preventable happens.
