As many are intimating on here, the key is to find something that works for you and to stay with it. I have a role model with whom I have lived for the past 56 years, and I should be more like her, my bride. Bev weighed 108 the day we got married and the most she has weighed was 124 when she had our daughter (7 pounds 3 ounces at birth). Today, she weighs about 114. She eats just about everything that I do but in more modest amounts. Interesting how she got this way. When she was in Pharmacy School at Pitt, one of her classmates teased her, "When you get older, you will be like all those Italian women, 5' 3'' by 5' 3"!" I believe that so affected her that she became manic about weight gain. She monitors her weight 3 or 4 times a week and if she gains a pound or two, she will reduce her intake until it is gone.
Lastly, something that has worked for me was a four-step process that I saw on TV years ago and the developer had a program call "I can make you thin" or something like that. It had four basic steps (and there are paraphrased):
It begins by rating your hunger lever from 1 to 10, 1 being famished and 10 being so full you can barely move. You should try to keep your level between 4 and 6 and not go over 8. Then,
1. When you are hungry, eat.
2. Eat anything you want to eat.
3. Eat consciously, i.e., set aside a time to eat, eat at a table and not while watching TV or reading, etc., tasting the food and being aware of the taste, chew thoroughly (15 to 20) times, put your fork or spoon down between bites. In other words, do not just shovel food into your mouth.
4. When you are no longer hungry, stop eating.
I am trying to use this in conjunction with Nutrisystem's plan.
