How Many Calories Do I Need?
September 22nd, 2007 by admin
On food labels, the “Percentage of Daily Intake” are based on a calorie intake of 2000 calories per day. This is an average. Everyone has different optimum calorie averages based on a variety of variables, such as basal metabolic rate, amount of physical activity, genetic predisposition, gender, etc. Men typically consume more calories than women (on average 2700-2800 calories per day), due to a higher proportion of muscle to fat.
Basal Metabolic Rate (BMR) is the amount of energy the body uses while at restto perform such involuntary functions as the heart beating, regulating temperature, and other organ functions. You can calculate your BMR using a number of formulas - often based around your weight. Note that the thermic effect (the amount of energy your body needs to digest) of food also has an impact on your optimum calorie intake.
