The laboratory evidence that carbohydrate-rich diets can cause the body to reain water and so raise blood pressure, just as salt consumption is supposed to do, dates back well over a century

[T]he salient question is whether the increasing awareness of [heart] disease beginning in the 1920s coincided with the budding of an epidemic or simply better technology for diagnosis.

~ Gary Taubes

What sets science and the law apart from religion is that nothing is expected to be taken on faith. We're encouraged to ask whether the evidence actually supports what we're being told - or what we grew up believing - and we're allowed to ask whether we're hearing all the evidence or just some small prejudicial part of it. If our beliefs aren't supported by the evidence, then we're encouraged to alter our beliefs.

~ Gary Taubes

It may be easier to believe that we remain lean because we're virtuous and we get fat because we're not, but the evidence simply says otherwise. Virtue has little more to with our weight than our height. When we grow taller, it's hormones and enzymes that are promoting growth, and we consume more calories than we expend as a result. Growth is the cause - increased appetite and decreased energy expenditure (gluttony and sloth) are the effects. When we grow fatter, the same is true as well.We don't get fat because we overeat; we overeat because were fat.
