Whilst I have a great deal of sympathy with the last poster's viewpoint..........
HAVE YOU STOPPED TO THINK SHE MAY HAVE A SERIOUS MEDICAL CONDITION . (other than emotional prob's -weak-will /gluttony/lack of self-control or discipline etc.)
there are a number of conditions which cause people to put on excess weight and the results are beyond the control of the sufferer.
However, one must face the real-world fact that an increasing percentage of the population are grossly obese through sheer greed and a diet of junk food.
Why should the self-disciplined,normal -sized person have to subsidise these people?
Yes, I do have experience! My daughter-in -law is a "big girl"....she didn't used to be, but everything and everyone else is the problem, not her ginormous portions and constant self-indulgence. no- expensive pre-made meals don't work if you scoff junk in between!.
Heart, respiratory, joint and diabetic problems are just around the corner....not to mention inacessible car, chairs breaking, doors and passageways too tight and the sheer humiliation that's self-imposed.
Of course, the PC brigade would have us absolve these poor,misunderstood, unhappy wretches from any personal responsibility for their own situation... they're victims, honest!.
