If you want to lose weight how many calories should you eat? What if you want to stay the same weight or gain weight?

With the Calories Calculator Pro you can determine exactly how many calories you need to eat to gain, maintain or lose weight. Simply enter some basic information about yourself such as Age, Height, Weight and Daily activity and CalCal will tell you how many calories you need to consume to reach your goal.

After you've determined your total calorie intake, you can use the advanced calorie sliders to adjust the Carb, Fat and Protein sliders to determine exactly how many grams of each you can eat under a specific recommended calorie intake.
