That's a whole lot of acronyms. Any links for people who want to learn more or learn how to calculate/measure those things?

TDEE = total daily energy expenditure - the amount of total energy your body burns throughout a day (fun fact, just by living you burn calories) RMR = resting metabolic rate - calories your body burns in a day just being a body (pumping blood, thinking, etc) TEF = thermic effect of feeding - it takes energy to digest food NEAT = non-exercise activity thermogenesis - non-exercise is just differentiating between things a person intentionally does as exercise--like walking to work vs going on the treadmill at a gym.

TDEE = Total daily energy expenditure. How many calories you burn in a day. RMR = Resting metabolic rate (aka basal metabolic rate). How many calories your body burns just to sustain itself. If you were in a coma this is roughly how much you'd burn. TEF = Thermic effect of food. Your body burns a small amount of calories just digesting your food. EAT = Exercise activity thermogenesis. How many calories you burn while exercising. NEAT = Non-exercise activity thermogenesis. How much you burn on top of your RMR but isn't exercise. For example, walking around a retail store burns calories even if it isn't categorized as exercise. These are the four components of your metabolism (TDEE).

If your goal is fat loss, I wouldn't bother too much with trying to calculate all of those. The process is simple: Go to an online TDEE calculator. Put in the numbers, get an expected TDEE (total daily energy expenditure, measured in calories). Then eat those amount of calories, minus 300. If after two weeks you haven't lost weight, do 200 calories less. Repeat until you are consistently losing weight. You might have to periodically lower your calories again, even if everything was working before.

  And be prepared that the online calculators grossly overestimate the daily expenditure, even well regarded ones like this: https://www.niddk.nih.gov/bwp https://www.niddk.nih.gov/bwp I'd take the advice posted elsewhere, start with 1500/1300 kcal for men/women and see how it goes for a month.
