Its all a mathematical equation. Your body needs X number of calories per day to function, everyone is different based on age, body build, activity level, and genetics. I could be anywhere from say 1800-2600, maybe more.

At the end of the day you need to be X number of calories below that number to lose weight. You can do this through eating less, or exercising more, or better yet a combination of both.

As for will power get it, if you want it bad enough figure it out.
