I hafta take issue a bit with the comments about "overeating". For folks with a presumably decent grasp of numbers I'm surprised at some of the statements above.
If 3500 extra calories translates into one pound, then all it takes to gain one extra pound
per month is (roughly) one extra tablespoon of fat (100 calories) or one extra apple (100 calories) every day. Not much.
Now I'll state right now that I weigh more than I should. More than I would like. I'm utterly indifferent towards ice cream and cookies, but I lead a pretty sedentary life. And I weighed exactly the same at age 17 as I do now.
If I had been "over" eating during the last 29 years... let's say that one extra tablespoon of fat per day (just 100 calories, remember.. not a bag of french fries or a Big Mac's worth...).. well, by now I would weigh ((12*29)+180)=
528 pounds.
Conversely, if I were to have eaten one
less tablespoon of fat each day than I normally do (or the equivalent of a little more than 100 calories in whatever form), in theory I would be long dead by now, having reached less than 80 pounds in the late 1980s!
There is something more subtle and complex at work here than just willpower or lack thereof. Setpoint theory? Evolution?
mathjak, some others on this thread have shown little compassion for those who struggle with weight problems.. I'm surprised that you've taken this to its nadir by ridiculing a fat lady
who is exercising!
I think some people were just made to store fat more efficiently which, in evolutionary terms, is a good thing. In our society of plenty, an historical aberration, this turns out to have some downside.
