You’ve heard the conventional wisdom: obesity leads to diabetes, heart disease, etc.

Me, I think obesity may be the cause of things like arthritis from the excess weight on joints, but if you’ve read the sidebar here, you know that I actually think that obesity is also a symptom, and what causes it is what causes diabetes and heart disease (among others): the Western diet. And our diet’s influence on inflammation probably contributes to things like arthritis as well!

But I’ve also been noodling something in my head for a while now. What to make of people whose excess weight winds up being hundreds of pounds or more?

And why aren’t many of these morbidly obese folks diabetic?

Doug McGruff (ER doc & Body by Science guru) has an interesting take on the Biggest Loser approach to weight loss:

[Bob and Jillian’s] contempt for the obese was obvious as they spewed insults (and saliva) in the faces of the contestants. I don’t care how fat or desperate I was, if someone did this to me I would punch them in the face and storm off the set. I checked in on the show between patients. The diet and exercise shown were prescriptive for ravenous hunger and ultimate failure. As I continued to work, I kept thinking about the importance of biologic signaling, and why it does not have to be this hard.

Read the entire post for more, but here’s the point:

The key to turning around these sorts of metabolic disasters is to send the correct biologic and hormonal signals. … A brief, but intense workout that fatigues the musculature activates growth hormone, testosterone and adrenaline which all signal to empty glycogen and fat, both short and long-term. A hunter-gatherer diet creates a low insulin signal which triggers the body to defend a lower body fat set point.

Contrast that with:

Overtraining (especially in the obese) triggers cortisol and other stress hormones. A low fat, high carbohydrate diet signals insulin release. These signals defend a high level of stored fat and drive hunger…a true prescription for misery and failure.

I know which approach I’m taking!

Ball-slapping A for effort!

One of the perils of blogging is having to deal with blog spam from people wanting to increase their page rank with search engines. Most of it is automated; a lot of it comes from non-English speakers.

Every once in a while though, you get a real pearl, like:

When I found this I had a strong desire to kick myself in the face to make sure I wasn’t dreaming. I got out of my chair and walked around the office with a huge smile on my face. I was in such a good state of being that I asked out this girl from the coffee shop that I like. Posts like this slap all others square in the balls.

Though it is still spam that is COMPLETELY unrelated to the post it’s attached to (and you will still delete it), you have to give the writer an A for effort :).

Campos on flying while fat

Paul Campos (author of The Obesity Myth) has weighed in (ha! a funny!) on the Kevin Smith / Southwest Airlines fiasco over at The Daily Beast.

Money quote IMO:

… consider how convenient it is for the airline industry to deflect a customer’s anger over ridiculously small seats—I’m thinner than approximately 80 percent of middle-aged men and I don’t fit into one very comfortably—on to “overweight” passengers, a category that includes, according to our public health authorities, nearly seven out of 10 adult Americans.

BTW, over on HuffPo, Lee Stranahan makes my other main point re Smith: Kevin Smith did not violate Southwest Airlines policy.

Back to Campos. His article is also worth the read for his criticisms of MeMe Roth of the National Action Against Obesity. But I like Tom Naughton’s approach even better!

Tom adds:

I actually find MeMe Roth more annoying than the sue-happy lawyer. This is a woman who is obviously naturally thin. She was born on the finish line and thinks she won a race. So now she feels justified in telling other people how to eat, and in criticizing pretty much every overweight person in the public eye. …

My advice: never take advice on losing weight from anyone who’s never had to work at it. They have no flippin’ clue what they’re talking about.

Word!

Fear of flying while fat

The other day, I got into a bit of a tiff on Facebook over the Kevin Smith - Southwest Airlines fiasco. Predictably, and sadly, the common response was “good for Southwest … it sucks having to sit next to fatties on planes.”

Let’s move?

Well, you have to say one thing about Michelle Obama’s recent announcement of the Let’s Move! campaign to end childhood obesity: it’s gotten a lot of people talking.

Let’s Move!:

has an ambitious but important goal: to solve the epidemic of childhood obesity within a generation.

Let’s Move! will give parents the support they need, provide healthier food in schools, help our kids to be more physically active, and make healthy, affordable food available in every part of our country.

On its face, it’s hard to criticize the idea of getting kids moving more and choosing healthier foods. But dig just a little, and very legitimate concerns are being raised.

I can’t recall where I first read the suggestion that metabolic syndrome is essentially a liver problem, but I find the idea curiously compelling. Over at PaNu, Dr. Harris responds to a question (see Christy on Feb 6) about improving insulin resistance or reversing metabolic syndrome as follows:

The chance for healing is dependent on removing the things that damaged you in the first place.

First, understand that it is liver insulin resistance we are trying to restore. Insulin is the way the pancreas talks to liver (hat tip Peter for that)

The liver is the principal damaged organ, and the knock-on effects to other organs, including the brain, etc follows from that.

The liver may heal if you stop damaging it with things that screw it up and cause inflammation.

Like:

1) Excess PUFAs especially (but not only) excess n-6 linoleic acid. Eat zero plant based vegetable oils (not counting coconut) No more than 1g n-3s per day as well as fish oil or CLO.

2) The hepatoxin called fructose. I advocate a ZF (zero fructose) diet if you have Type II or metsyn.

3) The hepatotoxin called ethanol. Zero that out, too.

4) A fail-safe approach to leaky gut. Endotoxin that leaks into your blood stream through your gut causes inflammation. Eliminate all gluten grains like wheat and all wheat flour. Eliminate all excess PUFA (step one). Consider a casein free diet until you have healed.

Eat as low or high a fraction of carbs as you feel like, unless you feel like losing weight and then you can read “how to lose weight” - that post is free and works as well as any book you can read.

I think the whole issue is more about stopping metabolic damage and consequent inflammation than it is about “managing” your hormones.

Interestingly, Matt Metzgar has made a similar connection between inflammation and obesity:

As far as looking at the ultimate cause of obesity, I used to lean more towards insulin resistance. Now after learning more over time, I am much more convinced the core problem is inflammation.

He, however, looks at the gut rather than the liver as the chief area of concern:

I also believe that one of the main regulators of inflammation is the gut flora. Balancing the gut bacteria seems like the most logical place to start in reducing inflammation.

Which ties in nicely with Stephan’s suggestion for effective fat loss over at Whole Health Source. But that’s a post for another time!
