Many thanks to an OA buddy who posted this on Facebook:

The floor of a Weight Watchers clinic in Sweden collapsed beneath a group of 20 members of the weight loss programme who were gathered for a meeting.

Building contractors are looking forward to updated building codes requiring floors in all publicly accessible spaces to be reinforced. To be fair, this could have happened at lots of Overeaters Anonymous meetings I’ve been to except, when I reflect back, the meetings where the members tend to be heavy, also tend to be lightly attended. Perhaps for OA, this is a self regulating problem?

Wait! Is there a mathematical formula that we can bring to this situation:
P = Population within 45 minutes of the meeting site.
M = Meeting size
B = Average BMI* of population within 45 minutes of the meeting site (+)
b = Average BMI of OA member at meeting (-)
A = Average months of continuous abstinence from compulsive eating(+)
W = Willingness factor (increases after January 1) (+)

B/b = Attractiveness ratio. Values greater than 1 are attractive.

Yielding this formula:

M = P x (B/b) x  (A/12) x W

Essentially, larger population centers start with a larger audience. Meetings where members are thinner** than the local population have a higher attractiveness ratio. The willingness factor is a tiny fraction and is determined empirically based on local experience and is affected by meeting facility, time of day, day of the week and competing meetings.

For the meeting I attended this morning, which had an attendance of about 100, W = 0.000005

Whew. Thank God it’s Lunch time!


* I know. BMI is not a perfect measure but it is a measure that is not unreasonable for most Americans, which is where I attend meetings.

** Thin is not well. I get this. The reality though at the OA Meetings I go to is that most members are not there due to under eating. Some are and they are very welcome.
