Resting Metabolic Rate Testing For Calculations

I have been doing 4:3 for 1 month now. I have used average assumptions with 500 calories on fast days and then various calorie intakes on non-fast... Between probably 1400 and 2300 for a special night out. I do not eat workouts but doing basic elliptical so not huge burns. All leading to daily average calories between 1000-1200. I have been thinking though how much better it could be if I knew my personal metabolic rate and I based calculations on that. I have been thinking about getting the test done. (Recognize it may require follow-up test as I get closer to goal weight - about 90 lbs total to go.) Anyway, has anyone used their own metabolic rate for calculating both fast and non-fast goals? Pros? Cons? Suggest it for others?

    Honestly don't really see the point.
    You are going to add an activity multiplier anyway, then you have the issue of logging accuracy, then exercise logging accuracy.....

    To me it's easier to just make adjustments to intake based on actual results over time.

    Hi there and welcome :) IMO, if you can afford it then why not ? Just be clear about that I've seen claims BMR can vary up to 50% depending on numerous factors. So getting a BMR test gives you ONE data point entry... a snapshot in time. Doing it on a day/week that mimicks how most of your "normal" lifestyle will give you the most accurate picture of the present state.

    If you suspect your BMR is lower than the numbers calculators give you, then it's just another tool in your efforts to shift weight.

    Last week there was a girl on the xxketo board that got a BMR test and interestingly her number were indeed lower.
    Then, the results! If you run my stats through a BMR calculator, the estimate is 1473 calories. The test results? 1219 calories, which is much lower.

    I've said it many times before, but I'll repeat it again: The online calulators are based on estimate AVERAGES. It's only a guesstimate. Like sjiomial said, if you want to know your TRUE TDEE, you can roughly calculate that by using your actual weight loss, maintenance and gain data.

    Good luck! ...and report back to us please if you go through with the test.

    Thank you both sjiomial and foamroller for thoughts. I appreciate getting perspectives from those who have been at this for awhile. Thanks again.
