You'll need to toy with your
nutritional intake and balance it against your daily
activity schedule. Generally, eat to support what you're going to be doing in the next several hours. Know that simply reducing your caloric intake to some fixed value for days on end will only result in overall scale-weight loss (you'll end up as a smaller version of your current self). Some degree of nutritional volume change-up is necessary. Doing things right, there's absolutely no reason why you cannot maintain the same scale weight, yet decrease your body fat in the process.
