You're right, we should all lament the possible passing of another way of judging people inferior to us.

He missed the part where Monsanto makes a weaponized form of the bacteria that you use against your enemies to make them fat.

I think the Soviets must have beaten us to it.

Someone made a comment yesterday on another site about how we are still living in the bacterial age. It's a strange notion, that bacteria still own the earth, but we are host to more bacteria than we are our own cells. It's such an interesting yet scary thing to think about - does higher order life exist solely as vessels for bacteria propagation?

Mind-bending, eh? It's not too scary a though though -- taking the evolutionists point of view, there is no "underlying" reason that higher order life exists. It exists because the processes of natural selection have enabled it to exist and reproduce. If bacteria contribute to the survival and reproduction of our species (they do), then they are simply part of the process. It goes both ways. We exist and reproduce be…

How's that saying go? 'Life - the whim of a few billion cells to be you for a while'.

Probably because it made the subjects want to eat more. There's no magic bullet for gaining or losing weight, you either eat more or less that your body needs.

It's funny, how you first said there's no magic bullet, then provided everyone with a magic bullet.

Dieting isn't a magic bullet you fool, it's long, hard and worth it.

I don't care if someone is fat. What I care about is the loons saying that it's healthy and fine to be morbidly obese and they use stuff like this to back it up. "Gut bacteria are the cause, I can do nothing" "It's genetics" No, it's calories in vs calories out. Maybe these bacteria make you want to eat more, maybe they somehow pull more energy out of food than normal gut flora somehow, in the end it doesn't really m…

"it's your body and you are free to do as you please."

When obese people fly they rarely buy two seats. They can pretend that their state of health doesn't affect the people around them, but they are deceiving themselves.

Well bacteria are a lot smaller than our own cells, so comparing them by count doesn't seem very meaningful.

By mass, bacteria is still the dominant lifeform on earth.

Gut bacteria are an extremely powerful system within our bodies and are mostly still mysterious to us. Imbalances of one type or another lead to large amounts of bacterial toxins being introduced to the intestine and the bloodstream, with wide-ranging mental and physical effects. I'm not surprised that contribution to obesity is among them. It works kind of like this: You eat too much refined/processed food, that is…

Tangential, but: is the whole obsession with fiber a bit misguided? If polysaccharides are largely responsible for feeding gut bacteria (good and bad), and your link recommends cutting them out, then by definition, we should be cutting out dietary fibers (most of which are polysaccharides). Fiber is mostly undigestible in our stomachs and upper GI tracts, but is readily fermented by (and feeds) intestinal bacteria.

Or am I missing something here? Someone with a bit more knowledge of organic chemistry and biology can feel free to chime in here.

Yeah, that's cool. Any idea how much mass of a human they make up?

Except we already have strong evidence to suggest that calorie deficit diets do not have a causal relationship with weight loss

I don't know if you meant something else here, but of course eating less causes weight loss.
