There are so many numbers out there, its hard to make sense of them all and which ones are more important and how they relate to each other.

Any thoughts or suggestions are certainly more than welcome (otherwise I wouldn't be asking). I get the concept to eat fewer calories than what you are using (that just makes sense) and BMI has been around for a long time, but what the hell do I do with the other numbers.

I used fitnessfrog.com and got my "stat's"

RMR - 1627
BMR - 1643
TDEE - 2259
BMI - 38

This sight has my calorie goal at 1,200. On the days where I work my laboratory job and my office job I stick closer to 1,000 - 1,200 and on the days where I work on a farm I eat closer to 1,400 and try to up my protein on those days. This seems to be working, I only started around a week ago and my dress pants already fit better.

    In terms of calorie deficit, BMR and TDEE are the only ones that matter. IMO.

    BMR is your calories burned per day at rest, no movement, no exercise. Basic body functions.

    TDEE is your BMR plus activity and exercise calories burned per day.

    Create a 500-1000 deficit on your TDEE and you'll lose an average of 1-2 lbs per month.

    If you're sedentary, and don't exercise at all, you could deduct from your BMR number, but never below 1200 as a guideline.

    TDEE minus 20% equals 1,800 calories. Since TDEE includes your exercise, do not eat back any exercise calories.

    Do not eat less than your BMR, 1643. Eating 1,000 calories per day is counterproductive.
