Daily Energy Intake vs. Daily Energy Expenditure. Who Wins?
Posted Jan 06 2013 5:00am
Call it energy intake. That’s when you take the food in.
Energy expenditure. That’s not only your physical activity;
it’s also your metabolism and core body temperature regulation.
It’s a lot easier to increase your energy intake than it is
to increase your energy expenditure. Eating too much food or eating too much
calorie-rich food, as you might have first-hand experience with, is a lot
easier than doing too much exercise. Right?
The day-to-day variability in energy expenditure is
estimated to be about 8 to 10% compared to 20 to 25% for energy intake.
Changes in energy intake, not changes in energy expenditure,
have the biggest impact on body weight.
