So I'm trying to calculate my TDEE using these two different calculators.

1. http://scoobysworkshop.com/calorie-calculator/
2. http://iifym.com/tdee-calculator/

I enter the information the same in both and one says my TDEE is 3075(scoobys) and the other 2440(iifym).
How are they so different? I'm trying to cut weight so I need to figure out how many calories I should be eating a day, but I can't seem to figure it out. I'm 18, 6ft (72inches) tall, 148.5lbs, and about 14% body fat. If you know what I should be doing differently please let me know. I workout for about 45mins-1hour monday through saturday.

    I have been using http://iifym.com/iifym-calculator/, but the best advice I can give you is to compare with as many websites as possible and see what is the most common TDEE.

    They may have rounded numbers here and there to get different values.

    I put you in at 3-5 hours/week moderate workout (scooby) and 6 workouts a week (iifym, mifflin) and got 2767 and 2614.

    Take the average and go with that. You can always adjust up/down from there. Nothing has to be set in stone!

    TDEE calculators provide an estimate of your caloric needs.. Pick one of the numbers, track everything, be consistent with your activity, and reevaluate after 6 - 8 weeks. If necessary make calorie adjustments and re-evaluate again after another cycle.

    Im eating around 2100-2200 calories a day to lose roughly 1lb per week. Is that too low of calories or is that okay?
