Data for weight loss on Atkins?

[burtonator]

Hey gang.

I'm a bit of a math geek / computer programmer.

Actually that's somewhat of an understatement

I'm looking for numbers on weight loss on Atkins.

Specifically. Date/weight measurements.

If I can get the data from say 10-30 people I can make a good trending report for the rate of weight loss on Atkins.

I'm specifically interested in stall points. How often we can see stalls. How long they last for, and the cliff after the stall ends.

I often have stalls for 2 weeks followed by 2-5 pound loss (due to losing accumulated water) in a short time period.

Anyway. I will share the numbers and graphs with everyone once they are created.

You can just add your numbers as a reply to this thread.

It would be nice if these were somewhat granular.... 1 day measurements are ideal but 1 week I think will work too!

Thanks!

You might have to modify your stall criteria. According to Dr. ATkins a stall is 4 consecutive weeks with the loss of pounds and/or inches. So 2 weeks without losing pounds and/or inches isn't considered an Atkins stall.

With that said, I have never been in a stall using the above definition because when the scale wouldn't really move (down a pound one week, up a pound the next, down 2 pounds one week, down 1 pound the next), I was losing inches.

Another factor you might need to have info on to make it meaningful might be how much weight people need to lose as well as how close to their goal weight they are/were at the various points.

@Elizellen to a certain extend these variables (errors, breaks, near target) can be smoothed across the data by either eliminating them or just blending them into the larger data set.

@not2late Sure.... I think one could define a strict 'stall' in the atkins world per his definition but maybe come up with another term like 'practical stall' or 'observed stall' for when someone is frustrated and feels that they aren't seeing results.

The point I was trying to make with the stalls is to show that the data backs you up.

Data doesn't lie unless you don't understand the statistics or manipulate the statistics to your outcome. I don't fall into either category

But you need to define precisely what is a stall. Over the years here on ADBB, I've seen posts complaining about "stalls" in which the poster lost only 5 pounds in 1 month---1.25 pounds per week isn't a stall by even traditional weight loss definitions which state 1-2 pounds per week is good weight loss.

So you need to set parameters for that stall to reduce the subjectivity.

I don't need to define a stall the graph the numbers and compute the derivative.

The definition of a 'stall' is a semantic matter outside of the raw data. It's just a matter of interpretation.

Well, if you don't define a stall, then your data will be too subjective and might not be very helpful. For example if your subjects think losing 3 pounds a week is a "Stall", then how is it helpful to someone who isn't losing any weight at all? But if you set your parameters and define what is a stall, then your data will be more meaningful and perhaps more reproducible.
