We seem to get this question every few months. Maybe a moderator could sticky this thread and then everyone's calorie counts would be in one place?
FWIW I am 5'4", 28 years old, 135lbs, I work at a desk job (literally sitting at a computer 40 hours a week), and I maintain on 1600-1800 weekdays and 1600-2400 weekends. I exercise 4-6 days a week for 30-120 minutes depending on if I'm injured or if I'm actively training for something.
Example: This week I lifted weights three times for 20 minutes each and swam once for 30 minutes. On the other hand, I'm working through two sports injuries and cardio is basically off limits except for swimming.
During the peak of my triathlon training last summer, I was running 30-45 minutes 2x/week, swimming 30-45 minutes 2x/week, biking 45-90 minutes 3x/week, and doing strength or yoga for 30 minutes 2x/week.
Obviously I was eating toward the top of my maintenance range when training, and I'm eating toward the bottom right now. To lose I have to eat 1400/day 6x/week with one day around 2000, at which point I will lose less than 0.5lb/week.
I'm also hypothyroid, although they say that since I'm medicated it doesn't make a difference.
