It doesn't quite work that way. Exercise is only part of the equation. How much you eat will determine whether or not you lose weight. There are plenty of people who can't exercise or can only exercise a little who still lose weight.
It works like this;
Your body burns a certain amount of calories just to perform vital functions; breathing, create new cells, organ functions, etc. This is called your BMR. It can be estimated based on your age, gender, height, weight.
You burn a certain amount of calories through daily activities; showering, house cleaning, making meals, running errands, walking to your car, etc.
And then you burn a certain amount of calories through exercise.
So let's use some imaginary numbers. Say your BMR is 1500 cals, you are basically sedentary and burn about 300 cals extra a day through regular daily activities. So that means it would take 1800 cals to maintain your current weight.
It takes a deficit of 3500 cals to lose 1 lb. That is -500 cals a day to lose 1 lb/week. If you subtract 500 cals from the 1800 cals to maintain your current weight, you would eat 1300 cals/day.
Now if you want to factor in exercise. Say you burn an extra 200 cals/day through exercise. Now your body requires 2000 cals to maintain your current weight and you could eat 1500 cals to lose 1 lb/week.
If you burn even more calories through your daily activity and exercise you may even be able to lose 2 lb/week or -1000 cals/day without having to eat too few calories.
Personally, when I was losing weight. I burned around 2000-2500 cals through exercise. Now that I'm maintaining, I burn 2500-3000 cals through exercise. I certainly didn't start out that way. I worked my way up as I became more fit.

"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. If you don't want to get bulky, lift heavy!
I can bench Nicole Richie, eat more than she does in a day before noon, I have a good 20 lbs on her but could still wear her pants.
All that matters is that you be the healthiest you, you ca
