    I figured mine, but my total intake comes out to less than my BMR should be. My BMR is 1608 and my TDEE is 1798. Subtract the 20%, 360, and I end up with a calorie goal of 1438, below my BMR. Now what do I do?

    You do absolutely no exercise then, because you picked sedentary.

    You sit around the vast majority of the day, maybe an hr of cooking a day, and that's it?

    That's sedentary.

    Glad this is helping so many of you.............I just posted my updated pics on the Success Boards from Day 5 to Day 100 - eating whole food plant based is my biggest factor but TDEE less 20% is for sure a close second! I am by no means done but the pics do help me see the progress and that this method works! Check it out:

    monica1184 - your calc's look dead on correct - remember if it has been some time undereating - it can take a few weeks for that metabolism to come back - but it will - and some have a slight gain until it turns back on - don't panic - my advice would actually be stay away from the scale, eat at TDEE less the % and weigh around 4-6 weeks later................good luck!

    ruthc69 - the concept is scary - but after you eat more and it really sinks in WHY you are doing this to fuel the body and burn the excess, the fear does go away - I actually am now always in awe at the body and how amazing it is and how smart it is to know how to stay alive - you gotta eat - you just need to - your body wants to be healthy and thriving - without eating too much.............keep me posted!

    calaz84 - what I found in researching this is that the TDEE # has your normal activity level built in by the level of activity you select - it's there - so for anything ABOVE my "normal activity" only THEN do I log in my exercise if I know it's more then typical and even then I only eat back SOME of the calories...............make sense?

    And if you are one who likes to see your exercise logged in as you do it, as many do, people have taken to putting in the exercise and manually changing the calories burned to "1" so it does not impact their daily calories since the exercise is already figured in to their TDEE amount.

    Good luck!

    OK, so I did my calculations and came up with the following: if I use the numbers given to me by MFP and eat back my exercise calories, it works out to be the same as the number of calories recommended to eat for my on fat2fit. Is this the way it should work out? It only balances out if I do work out. If I don't then I'm eating under my TDEE - 20%.

    Extra thanks to kmcosgrove for the original post and haybales for extra information and the spreadsheet that does all the complex math for me!

    After I switched from MFP values to this, my weight went up about a bit and plateaued for about a week, then it started coming back down. MyFitnessPal had me at 1270 calories per day, but this method bumped me up to 1880. I put in sedentary and use the spreadsheet (MFP Tweaks tab) to calculate calories I can eat back from exercising since my workouts vary from day to day. Now, just after two weeks, my weight is about 3 pounds lower than it was before I switched.

    I also like that with the extra calories, I can concentrate my workouts more on the strength training, instead of doing extra cardio just so I can eat more.

    Lightbulb moment! Energy saving lightbulb perhaps, as it's been gradually coming clear over the past few weeks.

    I lost a good chunk of weight 2 years ago with MFP, but it felt restrictive and was basically a diet. I came away with not much idea of what I really needed calorie-wise.

    Now I think I get it, and hope that eating a steady 1800kcal will shift a few stubborn lbs and get me on track for good.

    Thanks so much for your well-written post. The body fat calculator has helped me see sense.
