Sugar, not fat, exposed as deadly villain in obesity epidemic

28. But that's how science works

Scientists make hypotheses, test them out, look at the evidence, revise hypotheses. The original hypothesis, which made first-glance sense, was that eating fat made people fat. Sounds plausible and "duh!". You know, the "you are what you eat" hypothesis.

But, we test the hypothesis, look at the evidence, revise hypothesis and come out with sugar is the problem, and now, we have shown the mechanism for sugar -> fat.

That's how science works. Maybe this new hypothesis, sugar = fat, may be replaced with another hypothesis in a few years, but I doubt that since the mechanism for the metabolism of sugar has been analyzed. We have a much better understand now of how sugar is metabolized, compared to 30 years ago. Our evidence and knowledge is much better. But let's say the sugar = fat hypothesis is not quite correct and is tweaked. Well, that's what science does. We shouldn't grumble, we should exalt at the power of the scientific method.

Indeed, the change of the point of view from fat = fat (the we are what we eat hypothesis) to sugar = fat (the metabolic mechanism hypothesis) is a testament to the power of the scientific method and scientists willing to confront their own views and biases.

And there are lots of facts to back up the current hypothesis.
