Question 1085732: Fitness math problem:
1 pound of fat=3500 calories
If a woman eats 1000 calories a day and burns an extra 400 during exercise, how many pounds of fat will she lose a week?

Assuming the woman needs 2000 Calories (= 2000kcal) to maintain her current weight,
by eating only 1000 Calories a day and burning 400 additional Calories during exercise,
she has a deficit of 1400 Calories per day.
1400 kcal/day * 7 days/wk = 9800 kcal/ wk <<< deficit in kcal needed to maintain current weight
9800 kcal/wk / 3500 kcal/lb = lbs/wk
