I have been reading in the forums a lot lately people saying this...
"I use TDEE-20% but I calculated my TDEE at Sednetary and eat my exercise calories back"
Well my typically response to that statement is "You are doing it wrong" which always ends up in a debate about semantics etc...
Not to be nit picky but that is not using the TDEE method and when you this you have the potential to confuse people who are new and asking questions and trying to get educatd
TDEE by Definition is Total Daily Energy Expenditure which is
"The total daily energy expenditure (TEE) is an important calculation in the determination of the overall dietary and exercise practices of any person. The amount of energy needed by anyone to meet the daily physical demands will have two components: the amount of energy needed to maintain the body's needs at rest, the basal energy expenditure, expressed as the base metabolic rate (BMR), and the needs generated by the daily activity levels, which include employment, sport, and any other activities."
BMR is defined as the amount of energy required for the body to function of all of the essential body systems, including heart rate, brain function, cardiovascular function, and the work of the thermoregulatory system. The BMR is the energy used by the body at rest.
The method used by MFP is called NEAT
NEAT = Non-exercise activity thermogenesis
NEAT is the energy expended for everything we do that is not sleeping, eating or sports-like exercise. It ranges from the energy expended walking to work, typing, performing yard work, undertaking agricultural tasks and fidgeting. Even trivial physical activities increase metabolic rate substantially and it is the cumulative impact of a multitude of exothermic actions that culminate in an individual's daily NEAT.
So folks please when answering a question from someone who is perhaps new or lacking in this knowledge do not confuse it further.
Use the correct terms and when someone tells you "You are doing it wrong, that is not TDEE" accept it because it's not.
*On a personal note I use the TDEE method. I eat the same number of calories everyday regarless of my activity.
I personally got my TDEE from my own actual data after measuring my portions, recording and logging accurately for 3 weeks.
There is no guesstimation from a website (not bashing those sites as the seem pretty close), Just mentioning this because often times people are directed to those site(s) and there are differences in the numbers each give.
