The big thing with this method is that you have
to quit eating when you're full, and eat only
when you really are hungry. That's something that, let's face it, most of us (myself included) aren't
very good at. This is especially true when you think about the fact that so many of us snack at work and before bed, eat for "comfort", have HUGE servings given to us at restaurants, have been conditioned to clean our plates, feel pressure from others to eat what and when they're eating, etc., so on so forth. Sometimes it's easier just to be on a diet that gives you specific guidelines to stick to. hehe
Also, the article mentioned "exercise helped." Remember that you can loose some weight and be somewhat healthy without exercise, but you can loose even more and be even healthier in the long term with it.
Just as an aside....
Lately I've tried to eat just when I'm hungry and quit when I'm full, and to get about an hour of walking in a day (lunch and breaks at work). I've been doing this since I started my new job 2 weeks ago and have dropped a couple of pounds.
So it works!!
