Calculating TDEE based on calories in + weight lost

AlysonG2

I'm trying to get a better idea of my TDEE based on the number of calories I've eaten vs. the amount of weight I've lost. I just bought my food scale 3 weeks ago, so I'm only counting the last 21 days. I'm mostly just making sure I'm doing it right for now, and I'll recalculate once I have more data.

Here's what I've come up with:

For the last 21 days, I've eaten 39611 calories.
I've lost 5.4 pounds * 3500 = 18900 calories.

So (39611 + 18900)/21 days = 2786 TDEE. I'm 5'6.5" and currently 188.2 pounds. I have a desk job and exercise 5-6 days a week (plus chasing a toddler around), so this seems reasonable.

Am I doing this right or am I missing something?

regardless of the number, if you are losing, you are doing it right.

i'm 5"7' and 180 pounds, and eat 1750 daily.

Yes the calculations look correct to me. This is the same formula I use.

It has worked me in the last 6months where my average daily intake was 1700..TDEE is 2000 and I lose on average 3/4lb a week.

I'm a full-on type A personality, so it really helps keep me motivated when I know I have the right numbers and can control it

Yup, that's how I do it too! Good for you for realizing the best way to do it is based on your own results over time. Sounds like you are on the right path!

Great. Thanks!
