Those online calorie calculators have been discussed at 3FC before. IMO up to, say, 150 pounds they are probably fairly accurate, but after that they become pretty screwy to say the least, because basically it looks as though they take your body weight and multiply by some number or other, whether you weigh 100 or 200 or 300 pounds.
Personally what I would do is take my 'goal' weight - say 145 pounds - and then multiply that by 10-12, depending on how active I was (lower for less active, higher for more active) giving a calorie range of 1,450-1,740/day.
This month's issue of
Shape magazine had a worksheet to use to calculate the number of calories needed to maintain current weight - you would take that number and reduce it by 500 calories to get your daily goal intake for losing weight:
1. Your weight in pounds _____________ divided by 2.2 =_____________
2. Your height in inches____________ x 2.54 = ______________
3. 9.6 x # from Step 1: ______________ = _____________
4. 1.8 x # from Step 2: ______________ = _____________
5. 4.7 x your age in years _____________ = ______________
6. 655 + # from Step 3 _________ + # from Step 4 __________ - _____ # from Step 5 ___________ = __________ (this is your resting metabolic rate)
7. Multiply your RMR by the appropriate activity factor:
* If you are sedentary (you do little or no activity): RMR x 1.2
* If you are slightly active (you perform light exercise/sports 1-3 days a week): RMR x 1.375
* If you are moderately active (you enjoy moderate exercise/sports 3-5 days a week): RMR x 1.55
* If you are very active (you engage in strenuous exercise/sports 6-7 days a week): RMR x 1.725
RMR___________ x activity factor_____________ = ________________
(This is the minimum number of calories you need each day to maintain your present weight.)
8. # from step 7 __________ - 500 = ________________(this is the minimum number of calories you need each day to lose 1 lb a week.)
