A Few Notes About Calorie Counting

The heart of calorie counting comes down to understanding how many calories you consume and how many calories you burn.  If you consume 3500 calories less than you burn, this should result in approximately 1lb of weight loss.  In order to lose weight, you should aim for a basic calorie deficit so as to achieve 1 to 2 lbs of weight loss a week, rather than introducing too severe a calorie deficit. A severe calorie deficit may result in the loss of lean body mass, causing your system to lower the number of calories it burns to maintain itself.

Understanding and monitoring the calories you are consuming and burning is essential for a calorie counting process.  In order to help with this, BodyMedia provide a calorie monitoring device that can measure the calories you are burning and allows you to track the calories you consume in a wide variety of foods. This can help you keep track of calories burned and calories consumed to help balance the calorie equation.


The above calorie and nutrition data was taken from the U.S. Department of Agriculture, USDA National Nutrient Database for Standard Reference.
