The tools below are meant to give you a general estimate on where you stand. Always consult a professional before making changes to your exercise program or lifestyle.
The following is how long it will take to lose 10 pounds by burning some of the calories through exercise and cutting the rest out of your diet. (Keep in mind, though, that everyone's body is different, so you may find yourself losing weight more quickly or more slowly than you expected.)
Burn 500 calories / cut 500 calories a day = 5 weeks
Burn 500 calories / cut 250 calories a day = 7 weeks
Burn 250 calories / cut 250 calories a day = 10 weeks
Burn 100 calories / cut 100 calories a day = 25 weeks
