Close Goal Weight
Your Goal Weight is the weight you want to achieve. (If it's a lot different from your current weight, you might want to set a goal that represents only the first step. Even a 10-percent weight loss will significantly improve your health.)
Close Target Date
Plan on losing no more than a pound or two per week.  Otherwise, you may eat too little for good nutrition and your weight loss may be temporary.
Close Lactating?
If you are breastfeeding, check this box and the calculator will add calories for producing milk.
Close Tobacco User?
Nicotine speeds your metabolism, making you burn calories faster. (That's why people who quit smoking gain weight.) Check this box if you average more than one cigarette, one-half pipeful, one-quarter of a cigar, or one dip of snuff or chewing tobacco per day.
