Of course dieters have to do all the work, but the "Weight Watchers" plan succeeds in a fashion that is realistic and doesn't require pills; special meals; gymnasium memberships; special equipment; surgery or any other inconvienience.
The only things that you need are "will power"(to resist temptations to stray from your plan), "discipline"(to make the right choices when shopping or eating out), "patience"(a pound or two or three a week is recommended for healthy weigh loss), and some exercise or move anytime you can.
Most importantly is the "support" you receive at their meetings from others who are trying just as hard as you(more or less) to change their eating habits to a healthy normal lifestyle in "the real world".
Don't do it yourself or you'll fail and probably "never" know why - - because you didn't have the information necessary to make the proper choices "in the real world".
I highly recommend "Weight Watchers". They're the only weight-loss program the "measures" and "proves" their success.
My Dad would give me a hop-in-the-seat-of-my-pants if I didn't stick to this simple program. From a guy's point of view I can only say "just do it - - What are you a baby? Man-up you sissy! Let's go! ; this is serious business . . grit your teeth and stick with it."
. . . . I wish that was what they say at the meetings but they don't . .they're very nice and full of unending encouragement, praise and support.
