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.

The simplest way to look at all these associations, between obesity, heart disease, type 2 diabetes, metabolic syndrome, cancer, and Alzheimer's (not to mention the other the conditions that also associate with obesity and diabetes, such as gout, asthma, and fatty liver disease), is that what makes us fat - the quality and quantity of carbohydrates we consume - also makes us sick.

Just as animal research tells us that gluttony and sloth are side effects of a drive to accumulate body fat, it also says that eating in moderation and being physically active (literally, having the energy to exercise) are not evidence of moral rectitude. Rather, they're the metabolic benefits of a body that's programmed to remain lean.

We don't get fat because we overeat; we overeat because we're getting fat.

There is a theory that creativity arises when individuals are out of sync with their environment. To put it simply, people who fit in with their communities have insufficient motivation to risk their psyches in creating something truly new, while those who are out of sync are driven by the constant need to prove their worth.

In 1960, fewer than 13 percent of Americans were obese, and diabetes had been diagnosed in 1 percent. Today, the percentage of obese Americans has almost tripled; the percentage of Americans with diabetes has increased sevenfold.
