According to your height, age, weight
and moderate activity level, you need 1,900 calories a day to maintain your weight
. That is according to a calculator that is available on the Internet.
May I respectfully suggest that you journal your food intake, every morsel, and calculate the calorie content either from the package or by using a website such as http://www.calorieking.com. This will let you definitively see the amount of calories you're taking in.
