Well... I totally agree and I try to not let the numbers be my GOAL. I try to keep in focus that my goals are to feel better, move better, live longer, etc.
BUT I work in research
So numbers are actually interesting to me and I enjoy tracking, graphing, etc.
I am able to look at the numbers objectively though- I enjoy when I go down a pound. I enjoy making the calculations, etc. For me it is a bit of a reward. BUT I don't feel like my self worth or success are tied to the numbers.
I don't get discouraged if I don't see a loss or if I see a gain. I know that as long as I stay on track, the changes I want and the goals I have will come in time.
I do think I am a person who needs to track calories & exercise forever. I do not do well when not tracking. Maybe I don't have the right body signals to let me know when I have ingested enough calories and it is time to stop. I honestly feel the same after dinner now as I did when I was consuming twice the calories.
And I tend to get involved and oblivious and can sit at my desk for several hours straight and just not realize it. I set an alarm to get me out of my chair every half hour. I track my exercise because if I don't, I will get out of the habit of doing it consistently.
I think the goal for any individual is finding what works for him/her. I am very goal oriented and data driven. So numbers and charts motivate me.
I do think it is important though to not get too caught up in the numbers and to remember the real life goals that we are aiming for.
And the charts that are floating around out there are guides- not magic numbers. Does it matter if I end up at 135 or 140 or 145? Probably not. So I think especially when we get close to our goals, it is important to pay more attention to our bodies and less attention to the numbers.
When you are at the other end though... it can take a lot of pounds before you really feel and see a difference in your body. Seeing measurements and pounds changing with a tape measure and scale can help us see in a practical way on a more regular basis that we are progressing. I lose a pound every few days or so... I notice my pants getting looser, the weights feeling lighter, etc every couple of weeks.
I think I would get discouraged if I only used those more tangible, more important, but less frequent markers of success.
