Hyperinsulinemia: Cause or Effect of Obesity?

Is Elevated Insulin the Cause or Effect of Obesity?

The carbohydrate hypothesis, in its most popular current incarnation, states that elevated insulin acts on fat cells to cause fat storage, leading to obesity.  This is due to its ability to increase the activity of lipoprotein lipase and decrease the activity of hormone-sensitive lipase, thus creating a net flux of fat into fat cells.  I'm still not sure why this would be the case, considering that fat tissue becomes more insulin resistant as body fat accumulates, therefore insulin action on it is not necessarily increased.  Total fat release from fat tissue increases with total fat mass (1), demonstrating that insulin is not able to do its job of suppressing fat release as effectively in people who carry excess fat.  But let's put that problem aside for the moment and keep trucking.

My view on "safe" research

What's that old proverb that everyone used to forward around in the 90s?

Work like you don't need the money; dance like no one is watching; sing like no one is listening; love like you've never been hurt; and live life every day as if it were your last.

I basically view my research program this way now. I met with a senior colleague recently who started to dispense the "play it safe until you're tenured" advice, then stopped themselves midstream and said, "Actually, if you play it safe you probably won't get tenure."

I think the game is all about finding exciting problems to work on and having the motivation to work on them (and getting students excited about working on them). It's also about aligning yourself to what people want to fund. We certainly seem to be in an era of applied research being popular - which is great for most computer scientists, though I do feel bad for my colleagues in theoretical fields.

Still, I think it's possible to be well-aligned with the desires of funding agencies and administrators while also pursuing dangerous ideas. It's all about spin.

i'm feeling a little under the weather today.....hope to be back tomorrow w/ more pep in my step.

All in a day's work

Today I received my first "Yo Professor!" email of the semester*, had a student sitting in my office providing an unsolicited out-of-the-blue trashing of some colleagues, and, during the meeting, had a student who I've never seen before just walk in to my office asking to borrow a stapler.**

Last week another female STEM professor and I were walking down the street and a car of young men drove past and started honking and shouting. And another almost-student posted very bizarre ethnic and racial slurs online.

I think we need R. Lee Ermey to give the opening speech at orientation, whoever is doing it now is clearly too much of a softie.

Apparently it's not just me having fun encounters with students this week! Must be all the crazy weather.

--------------------
(*) Actually, at least he called me Professor instead of Mrs., or, worse, Mr. (That gender confusion happened last week, actually. "I'd really like to talk to Dr. FCS about his research program.")

(**) Ok, so it's Labor Day, so maybe the main office was closed. But it seems to me he could have knocked. And left when he saw another student was in my office. And, apologized and/or left when I growled and scowled. @Piggie(Oh, Ermeyyyyyyyyyy).

Catered Paleo Dinner with Yours Truly

Gil Butler, organizer of the Western Washington Paleo Enthusiasts group, has organized a catered "paleo" dinner on Sunday, October 9th.  He will be screening the first episode of "Primal Chef", Featuring Robb Wolf and others.  He invited me to give a short (20 minute) presentation, which I accepted.  There are still roughly 30 spots remaining [update 9/21-- the event is full].

The event will be in the Ballard neighborhood of Seattle and the price is $15.76 per person.  I will not be paid for this talk, it's just an opportunity to share ideas and meet people.
