Resting Metabolic Rate test

[🅺🅸🅼🅼🅸🅴🅺 296]

It's not required for surgery, just something I wanna do and my surgeon's office offers them. They apparently strap you down to an EKG and some sort of breathing machine that determines how many calories you burn at rest. It has to be done fasting. Anyone ever had this sort of test before?

I had one a few years ago. It was interesting how much less I needed than anything I'd seen on the web or through calorie counting apps. It was a very, very first step in my thinking about maybe doing surgery. I really couldn't eat that little without some other tool.

Once I'm in maintenance, I'd like to do one again, just to gauge how much I should be eating

Interesting!!! I've used BMR calculators before but that's all just a guesstimate. Did you get your results immediately or have to wait?

My recollection is that it was immediate, but this was a few years ago, so my memory may be faulty.

I had it done. I had to breath into a little mouth piece for several minutes. Aside from some drool running down my cheek it was easy. I got my results immediately and believe the results to be pretty accurate.

Hah! (dangit, there's no drooling emoji here lol) In what ways were you able to use those results?

I don't have the exact number in front of me but I know the results showed my BMR in the low 2,000/day. It was a reality check that I often overate and how much I overate. Since I didn't bother to track food I didn't realize how many calories I actually consumed. It also pointed out how inactive I was......

While I haven't had the same test re-done, my gym does have a fairly advanced body fat/skeletal mass/water scale. Based on my current weight and muscle mass my BMR based on that is 1498/day. Makes sense given the loss in weight. The new number is helpful because now I track food/calories/nutrients and I track exercise/calories burned by way of a heart rate monitor. I have consistently stayed within 2-3 pounds of my current weight and increased my muscle mass using this method.

My new goal is to continue to increase my muscle mass. That is proving to be a difficult balancing act!

I'm blabbering on....in short it gives me a tool or guideline on how many calories I can eat in a day. Keeps me honest. Keeps me exercising. Of course not all calories are created equal so I am mindful to eat the stuff on my program.

Ahhhh that makes a lot of sense!

I've used this TDEE calculator for 2 years https://tdeecalculator.net and I was always told to take the average of my BMR and my maintenance calories in order to have a # slightly higher than BMR and slightly lower than maintenance to keep from jacking up metabolism. Apparently it helps keep you from entering into a caloric deficit, which on Keto, tends to cause weight loss stalls and/or gains. I'm super curious to see how close the # from the RMR test is to this calculator.

In your position I'd definitely want another one to compare the two! I love stats!
