This is why WLS works and Diets don't

I was updating my VSG research links when I came across this study:

Medical and surgical treatments for obesity have opposite effects on peptide YY and appetite: a prospective study controlled for weight loss.

In the study, they had four groups with eight subjects in each group. One group lost weight through "medical treatment", 8 were "lean" (i.e., not obese), 8 had RnY (gastric bypass), and 8 had the sleeve. They then measured their appetite after losing weight and concluded:

RYGB [bypass] and SG [sleeve] increased PYY [a hormone that helps us feel full] and reduced appetite. MED [medical treatment] failed to produce changes. Different effects occur despite similar weight loss. This suggests that the weight-loss effects of these procedures are enhanced by an increase in PYY and satiety.

Translation: Bypass and sleeve have a positive effect on appetite and satiety. Just losing weight without those surgical interventions does not.

My anti-New Year's Resolution Resolution

This time of year people think a lot about how next year will be different, maybe even make New Year's Resolutions.

As I mentioned last year, I don't do New Year's Resolutions per se and here is why:

Power balance bracelets are a scam

That's a headline that greeted me on Facebook this morning. It appears that the agency in Australia that parallels our FDA has made the company that makes them stop claiming they increase power, flexibility and balance. (Our own FDA has done nothing, by the way.)

I'm not surprise, honestly.

Visting my old (fat) life

This week I decided to go to my figure skating club's Holiday party. It always includes a free skating session so I decide to finally get back on the ice. I was scared though because it's been years... so many years that I am not sure how long it's been... at least three years, maybe closer to four. I also had no skating outfits that fit any more.

Dangerous advice from people who should know better

There's a lot of nonsense spewed on the Interwebz -- everything from the Flat Earth Society to Holocaust deniers -- but unfortunately not all of it is so obviously the work of crazies. Sometimes people with credentials or organizations with official sounding names are the ones spewing the nonsense.

As an example, we have a famous WLS surgeon who had a reality tv show, has written books on the subject and gives speeches at various WLS conferences around the country. Said "expert" has recently become a convert to the vegan lifestyle. Which is fine. For him. But said "expert" is not content just to wipe dairy, eggs and meat from his own diet. No, he wants you and I to eat that way too.

Like most fanatics, he tells us that it's good for us. That meat is bad for us. That no one, not one person, needs more than 60 g of protein a day.  That there is no such thing as a protein deficiency. That there are no symptoms of this imaginary deficiency. Oh and if we need to get more protein our diet, a good source is... Broccoli!

He also tells us that we should listen to the Physicians Committee for Responsible Medicine.

The problem with this advice is simple: it's bullshit.

MacMadame has a tattoo

It's been 2.5 weeks since I got my tattoo and I'm just now getting around to writing about it. This is mostly because the photos that will accompany this post needed some culling and Photoshop work and I've just not wanted to do it. But it's also because I'm in a bit of a post-IM funk and also have my first cold in 2.5 years ... which I'm also blaming on IMAZ because supposedly doing an Ironman will compromise your immune system.

Anyway, I have been talking about this tattoo pretty much since I signed up for IMAZ or maybe even before that. Knowing myself, I decided I had to get the tattoo immediately after finishing or I would never get around to it. (Similar to my idea to get a naval piercing which has never happened and probably never will at this point because you aren't supposed to swim for weeks after.)
