Calorie intake

Where or how do you calculate the number of calories you should be taking in each day?

Re: Calorie intake

One way to calculate your caloric requirement is with the Harris-Benedict Formula:
I use the following formulas:

Women: BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)

Men: BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in year)

This gives you your Basal Metabolic Rate (BMR)
Now that you know your BMR, multiply your BMR by your activity multiplier from below:

Activity Multiplier
Sedentary = BMR X 1.2 (little or no exercise, desk job)
Lightly active = BMR X 1.375 (light exercise/sports 1-3 days/wk)
Mod. active = BMR X 1.55 (moderate exercise/sports 3-5 days/wk)
Very active = BMR X 1.725 (hard exercise/sports 6-7 days/wk)
Extra active = BMR X 1.9 (hard daily exercise/sports & physical job

Your BMR X Activity Level = Calories needed for maintenance: what you need to sustain your body at status quo.

Re: Calorie intake

That's pretty good sbdot...gets me almost right on. I agree completely with the BMR (mine at 1905 seems almost exact) but the effect of exercise seems less for me.
But the Mod. activity (where I'm pretty sure I am) takes me to 2952.7 and I'll put on weight there.
Even the 2619 of Light Activity might cause a very very slow weight gain...
And I do hit the gym 5 days a week.
Perhaps though I am not working as hard as the averages (but I AM 62) and maybe that 2619 might be closer than I think.

Good formulae though.

I guess that from the CONSTANTS (women: 655, and men:66) women are much more alike than men in BMR because something like HALF of their BMR is determined by their "femininity." Interesting!

I'm putting the formulae in my DOCUMENTS folder!
