Also, do not set your goal weight based on somebody else's weight. Two people who are the same heights can look very different at the same weight. It has to do with your build and shape and muscle mass. I have found it best to shoot for a certain clothing size (again, be reasonable about what size you can maintain) and then figure out what weight correlates with that size for you. And yes, I am all about the number on the scale. I know some people are successful without ever weighing themselves and that is great, but this blog is about what works for me. And I weigh myself pretty much everyday. The number is my indicator of what I can and/or should eat that day. I like that my scale is digital and shows the tenth (as in 138.9). That way I can monitor little gains or losses before they become whole pounds.
That is not my feet, nor my scale, but you get the idea, right?
It is best to check your BMI at your goal weight and make sure you fall within the proper range. You can find an online BMI calculator at http://www.mayoclinic.com/health/bmi-calculator/NU00597 . My BMI is at the high end of my "healthy range", but I don't care. I have found the number that works for me.
