My wife is on Weight Watchers. It has been working well enough for
her. But a consistent source of amusement for me has been the "Points"
system, which penalizes fat in the extreme, to the extent that if one
were try to do low carb and follow the points system you'd have to
starve yourself to stay within your points allotment.
I decided to look up the formula for the points system and input my
average daily calories and fat grams from fitday.
For the last month
Avg Calories: 2075
Avg Fat grams: 125
Avg Prot grms: 124
Avg Fiber grm: 12
The points formula is: Calories / 50 + fat / 12 - min{fiber,4}/5
That last part is a bit dodgy, it means that you take the number of
grams of fiber in a serving, or 4, whichever is less, and then divide
by 5. As I don't really have good per serving data, I will just knock
off 3 points as a good guess for fiber.
So how many points do I eat a day on average?
2075 / 50 + 124 / 12 - 3 = 49 points
My wife gets 28 points a day, and she weighs a little bit more than I
do (they assign points by weight, your points allotment going down as
you lose).
According to Weigth Watchers I am eating an insane number of points and
should be gaining weight - but I have in fact lost about 15 lbs in two
months. Huh.
