Having trouble w/ calories? Read this :)

Here is a formula to calculate daily caloric needs that can be found in the Insanity nutrition guide, but can be applied to any workout program. Hope this will be helpful to those of you struggling to figure out how many calories you need per day :)
Step 1 BMR
For women: 655 + (4.35xweight in lbs) + (4.7xheight in inches) - (4.7xage in years)
For men: 66 + (6.23xweight in lbs) + (12.7xheight in inches) - (6.8xage in years)

Step 2 choose your activity level and multiply step 1 results by that number to get TDEE
1.2 sedentary
1.375 lightly active
1.55 moderate
1.7 very active
1.9 extremely active

Step 3
If you want to lose weight subtract 500 from your results in step 2 and this will be your daily goal. If you want to maintain your current weight use the number you got in step 2. If you want to gain weight add 250-300 per day to the number in step 2.

This is a simple equation and hope it will help some of you that are confused!

    So to maintain I need to eat 1,401.35. If I subtract 500 I need to eat 901.35. :( Still going to eat my 1200-1300 a day but that explais why I've been losing so slowly.

    That's just the standard but less accurate Harris Benedict BMR and TDEE calculations found on many different sites.
    fitnessfrog, scooby, fat2fit, ect.
    MFP at least uses the more accurate Mifflin BMR calc - Tools - BMR calc.
    Of course, MFP activity levels contain NO exercise in them, since it's designed to eat them back when actually done.
    Those TDEE activity levels does include exercise - so totally different thing, and you must use MFP totally differently if using that method you are describing. You would NOT log exercise in that case.

    Using a site that does the math for you is much less confusing. Plus those activity level descriptions is missing anything meaningful as to what it means, they normally include days/hrs of exercise each week that would apply.

    Can also use a spreadsheet that lets you save your info, plus use the more accurate BMR estimate based on bodyfat%.

    Thanks for the formula. I have to say MFP was very close.

    Formula: 2078

    MFP: 1980

    Guess I have a little more cushion in my goal number.

    I'm aware this is standard and have definitely done my research on those sites as well as seen the spreadsheets which are great. Just trying to make it simple for someone to glance at and easier for people who are confused :)
  • Mine came out to 2007 which is way more than the 1200 MFP gave me. That's a huge difference. That is more close to what I probably ate before watching calories and working out. I guess I was maintaining then but I can't even imagine eating 2000 calories a day now. That's a lot of egg beaters and dry toast. haha

    Obviously the formula doesn't work for everyone and it took me a few times to actually do the calculations correctly, but my 1850 a day seems to be working :)

    You're right it does it worked for me for a while but then I had to do some reassessing and adjusting just thought I would share my experience with it and help others.

    MFP doesn't include exercise calories in the number it gives you.

    I figured mine according to the Insanity booklet and it came out to 1536 a day - doing it like you describe above it comes out to 1236. Hmm - now I need to go back to my book and look again. I'm struggling eating 1500 a day - I couldn't imagine going down to 1200 again and keeping my workout schedule.

    OP, I think you should clarify that the activity level should include exercise (unlike MFP which only includes normal daily activity). This may be why a few people have come up with very low numbers.

    Unless you are 18, 100 lbs and 5' tall, I don't think you did it correctly. Don't forget to add in the activity multiplier.

    AND for everryone else, this number would then INCLUDE your exercise so you wouldn't eat that.

    Hi thanks for this Mine i just lowered yesterday to 1700 and according to this calculation it should be 1834 very close thanks so much for the info :flowerforyou:
  • This can't be right. It puts me to lose weight at eating 851 calories. I would pass out. Will stick with my 1200 and eat back my exercise calories like I have been doing.

    Hmm

    According to this formula:

    BMR - 1908
    TDEE - 2623

    -750 (1.5 a week like I put on MFP) = 1873

    MFP Gave me 1510

    So I guess if it thinks lightly active burns 360 calories a day (which makes sense) this would be correct.

    Thanks OP!
