I agree with all the above. And you need a lifetime eating plan that is EXACTLY tailored to you, your food likes/dislikes, how much you cook or like to cook, what you can live with. How much work you have to do to get going losing weight. Lots of fine tuning, so you can live with it!
Also, exercise is crucial - I can live with lots of walking and a bit of running, so that is what I do. And I had to cut out eating pasta and rice, except once in awhile. And I like pizza crust, so I skip the cheese part and everyone gives me the crusts; or I eat ONE piece, and a few crusts and that is a lot better than eating 3 whole pieces.
And it is good to find staple foods/meals that YOU like and can eat regularly, and can fix without thinking. I tend to overeat when I am starving and have to fix the kids' meal...so I make sure I have sugarfree jello or a yogurt, to hold me. So I feel looked after!
