LindaT.... (all)
Your doctor is also CORRECT!
Look at this.....
I am currently reading The American Heart Association No Fad Diet book. I do recommend this to all! Good book. Here is what it says about figuring out your calories to maintain your current weight. (This is taken (typed) right from my book)
Multiply current weight in pounds ____ x 10 = Base calories ____
Multiply current weight in pounds ____ (same as the # on 1st. line above)
If not active: x 3 = ____
If moderately active: x 5 = ____
If very active: x 8 = ____
Activity calories = ____
Add base + activity calories = Total calories to maintain your weight = ____
Total adjusted calories = ____
I think this is the same as what Susan says above.. just different numbers.... and also.. this way is using your current weight... and NOT the ideal weight. Maybe that is the difference. To maintain my weight right now at 193 I would have to eat 2500 to 2900 calories a day!!! WOAH.. that is a lot!! And now if I used the numbers that Susan stated above (13, 14, and 15) I still come out with the same results if I use my current weight of 193 to total this up. But Susan was using the ideal weight... our healthy weight.
I think it all make sence.... and it is all the same math.. just different starting numbers (idea weight verses current weight).

I hope I explained this where everyone understands it haha.
