Or I don't know, you could just infect yourself with some nasty disease. Sick people tend to lose weight, too.

Just saying that weight loss in itself is not necessarily saying much.

This work came from my lab -- most of the research was completed before I joined. AMA I guess...

Edit: I'm walking out the door at the moment.

I think it's fascinating to imagine a future where scientists finally discover the "anti-fat" drug. I believe it's bound to happen in our lifetimes. In a world where only the poor are fat, it would be very interesting to see how this affects the perception of attractiveness in middle class/upper class society. Would we adapt to value knowledge above physical appearance?

Aren't we living in a world in which only the poor don't have cell phones?

On the other hand, we're talking about a drug that selectively turns off blood flow. That it affects fat cells was only visible because subcutaneous fat is rather obvious.

But what other cells did it affect? It's not well known yet. For all we know it's stomping on some neurons, or diddling with kidneys, or weakening the left ventricle of monkey hearts. It's too soon to get excited.

There is a lot of fat in the brain. I realize it was targeting adipose fat, but that is still disconcerting until proven otherwise.

They mention in the article that it had a dose-dependent effect on renal function that was both predictable and reversible. You're definitely correct, in that I wouldn't trust any fat-loss mechanism that works through accelerating apoptosis without extensive human research.

However, it's effect on various cells is understood, as it is determined by the type of protein evident on the cell surface. Fat cells are understood(under the vascular mapping prepared by the lab in question) to have this in far greater numbers than any other cell type.

The obvious question is what will happen to the excess blood sugar, when it's no longer being taken up by fat cells. Would this promote insulin resistance?
[+] tansey|14 years ago|reply
They address this in the article, noting that treated monkeys used 50% less insulin.

Anyone else wonder where they got obese monkeys from? I guess they feed them up terrible diets or something...

And because the article had no pictures of obese monkeys, and I was curious to know what an obese monkey looked like... heres a google search : http://www.google.co.nz/search?q=obese+monkey&um=1&i...

The article states they were spontaneously obese and did not make them obese. They were fed the same foods as other monkeys, they just exercised less.

Disappointing, I really wanted to see a picture of before/after monkey mug shots.

Obesity has been an annoyingly difficult problem to "solve". I say "solve" because in most cases the solution is simply to eat sensibly and not be sedentary (ignoring people with genuine physiological problems such as thyroid conditions).

But there is unquestionably a desire for people to be able to eat essentially what they want and to stay slimmer older. At some point someone will figure out a pharmaceutical solution to that problem and make a fortune (probably eclipsing what Viagra did for Pfizer). Current drugs that block appetite and/or fat absorption tend to have nasty side effects and questionable utility.

Killing fat cells is certainly a novel approach, especially considering that relationship between fat cells and weight changes (eg fat cells will increase in size to a certain point before growing new fat cells), one that may even be relevant for people who have lost a lot of weight.

And solving lung cancer is simply a matter of getting people to not smoke. Having tried and failed for 15 years to just "eat sensibly", I can promise you there is a whole lot more than just wanting to be able to have your cake and eat it, too.

And lest you think it's just a will-power thing, I spent years on narcotics for pain management and had few problems getting off those.

The deck is stacked incredibly against obese people. To wave it off like that is to vastly underestimate the root causes.

cletus, there's tons of research to suggest that simply being overweight perpetuates being overweight because in the vast majority of individuals, being overweight in the first place triggers all kind of "physiological problems" -- such as insulin problems (Syndrome X), liver problems (non-alcoholic enlargement), hormonal problems, uterine problems (PCOS), etc., which all conspire to make you hungrier, fatter and actively prevent you from losing weight (BEYOND just making you hungrier). And that is without even considering "set point theory" as described by the research of Seth Roberts.

Once you gain weight, you are basically screwed.

We're not meant to live in such abundance.

Monkeys can have a good life now!
