Lose weight JUST exercise

Most of you that know me personally know that I am extremely over weight, but to some peoples shock and amazement I am not here by choice. Every thing that seems to go wrong with you, people say lose weight, and that will cure it. Do people think that I would not want to be skinny, and wear all the clothes that are popular, not have to go to the baggy section. Yes I know , the answer to losing weight is eating less and exercise. But in talking to some over weight people in the last few weeks, I have discovered something, I think there are a lot of over weight people out there that do not eat enough! My brother has chosen a new career path as a personal trainer and I am his pet project ( I don;t know how I feel about that ) and I had to write down what I ate and how much, and he told me. "Amy, you do not eat enough." WHAT! All my life I have been taught fat people over eat, and to now be told I need to eat, is mind boggling. So three meals a day, and let me tell you this is not easy for me, I find myself feeling guilty for eating, or for having a snack. A snack, fat people can not snack. I know my idea and perceptions are wrong, but believe it or not there are a lot of people out there that believe that. Then he said the nasty terrible word, exercise. I explained to him that a person as out of shape as I am , that is like saying , 1 tsp of Castor oil, you know it works but it tastes terrible. His answer was to just get out and do something, Ok, sounds easy, like what? Take a walk,anything. But for a person that has not done something like this on a daily basis ,and never had to exercise when they were younger to keep an ideal weight,this is more a chore than you think. Just exercise, to me comes with all the uncertainties that a new job would, lets face it , it is a major life change, and to start exercising hurts. Then you have to keep doing it, even though your muscles are aching, but wait that is a good ache because you know you are getting in shape. Is that like arthritis hurting is good because you know you are still alive? Well I am going to try this new concept of JUST EXERCISE, and see how it works, but I do not think I am going to do it with a smile on my face in the beginning.
