BMR and TDEE Explained for Those Needing a Guide

Ummmm....I'm confused. It spat out two formulas that are DRASTICALLY different. One BMR that doesn't take body fat into account is 1936 calories. The one that mentions the body fat says 1353 calories.

However when it shows how much to eat, I can't tell which it's in reference to. For sedentary it's 1697. For lightly active, it's 1944. Moderate is 2192.

I'm..so confused.
23F
5'4
CW 250 lb
GW 140 lb
BF 60.1%

Walk maybe 0.4 mile to and 0.4 from work (to the parking lot, total distance round trip is about 0.8 miles) and sit at desk all day. I try working out for 30 min every day, but that doesn't always happen.


Mfp has me eating around 1340 calories to lose 2 lb per week. When I eat 1800, weight doesn't drop.

Did you use katch-mccardle? Don't use it, it's only accurate for relatively lean people.

I never know what to pick for my activity level. I usually pick the moderately active level with 3-5 days of exercise per week, but what counts? I don't exercise a full hour every day. A typical week for me is three crossfit classes (they are an hour to an hour and fifteen minutes long but I'm not constantly moving, there are warm-ups and mobility and time when I'm setting up for weightlifting, etc., and of course it's not all cardio). I also run 3-4 days per week...let's just say 3 days is usually the norm, maybe an hour long run on Saturday, one thirty minute run on Monday, and some intervals on Thursday. And then I do an hour long yoga session usually once per week. Some weeks I may do spinning or riding my bike, but that's not the norm. So is moderately active good? I always worry that I'm over assuming.

Also I have a desk job and spend about an hour commuting. But I do stand at my desk a couple hours per day. And I have no kids so I don't chase them around or clean.

Is there a new link to tools for this purpose? Went to the one posted on 1st post and AVAST blocked it as a major malware threat. Avast is usually quite good and doesn't typically do that for no reason (I've had Avast for years and this has happened only twice, so something is setting it off), so I need to find a different calculator. Thanks

Can I get some help please?
Clearly I've been lead down a wrong path and am now freaking out about eating so many calories.

I now may as well be new to this because I've been doing it wrong for so long...

My main points are these; I will expand below
-Am I calculating my daily calories correctly?
-How do you manage to eat those calories on a GF diet?
-What activity level should I choose?

So I'm a 29yr old female, 106.2kg, 168cm tall
BMR- 2160
TDEE- 2592 sedentary or 2970 lightly active
Less 20% as my goal weight is 80kg
Is this correct?

I've used 10 other BMR calculators which tell me my BMR is around 1840 and my TDEE is 2023 (sedentary) and to eat about 1650 cal. But from my understanding is is that you should be eating at least your BMR?

Activity level- I work 5, 10hr days at a desk job. I have kids, I hardly exercise. Hence the recommendation of 1200cal I've been eating for sometime now (not a doc nor researched by me, was from a fitness professional). I did not eat my exercise calories. So eating much much less than I should on days I actually do exercise.

I have been trying to walk twice a week. One walk 30mins, the second 1.5hrs. but have only just started this.
Which activity level should I choose?

I've recently been told to try a GF diet by my doctor as it seems to be the main contributor to my stomach issues. Bloods showed nothing bad *sigh and *hooray, so waiting on a endoscopy.
So after eating 1200cal for so long, how do I start eating sooo much more without eating that gluten free boxed crap and no breads etc?
I have been eating mainly salads and meat but sometimes struggle to get my calories over 1200.

I turn 30 in a month and don't want to be bigger than I already am so am worried about eating more calories in the short term, even though it will be better in the long term...

Sorry for the long post, just so confused.
Thanks in advance

thanks for breaking this down. Now I've got to get my appetite to cooperate.

HI, I've just tried to access the fat2fit website but my computer has blocked it due to a virus warning. is there now another site i should be using instead? I found a site to work out my % fat but cant find one to enter that into to calculate BMR. Thanks

Thanks! I am going to double check mine
