The main issue is body composition (see the body fat calculator for more). Calorie expenditure will vary depending on the ratio of body fat to muscle or lean mass. NOTE that as our bodies adapt to exercise and our body composition changes - so will the amount of Calories burned.
The definition of a throttle is a valve that controls the fluid flow. An example of a throttle is a car part that controls how fuel moves through the system. Throttle is defined as to control the speed of an engine or the flow of fuel in an engine, or to hold down or choke.
The throttle body controls the amount of air the engine takes in, and when it gets dirty, the engine can't idle smoothly. So before you take the car into the shop, consider taking 10 minutes and cleaning it yourself with a spray can of throttle body cleaner and paper towels. You just might save a bunch of money and thereâs a good chance youâll cure the problem.
