    Ok - So im lost. MFP tells me to lose weight I need to eat 1600 Calories a day, thats at 2pound loss a week - on http://iifym.com/iifym-calculator/ it tells me to eat 2500 calories a day, thats to exact data.

    Data is :

    CARBS PROTEIN FAT FIBER CALORIES
    GRAMS per day 249.9 196.8 63 51 - 64 2354
    GRAMS per meal 83.3 65.6 21 17 - 21 785

    How can this be? which do i listen too?

    Step 1: Calculate Your TDEE (daily calories required)

    MFP Calculator =/= TDEE IIFYM Calculator

    They are 2 different calculations. If you are going to use http://iifym.com/iifym-calculator/ you dont eat back exercise calories on MFP. All of your work/exercise/activity is figured into your TDEE. So if you record calories burned in an activity on MFP use 1 calorie.

    MFP is setup to record and eat back exercise calories.

    I hope that answers / helps.

    I was following MFP's calorie recommendations and have been working out like a fiend....5 days a week up to 11 workouts in total. And, I've been starving. I have done this for months and lost nothing and actually gained inches. So, I tried IIFYM and increased my calories and followed my macros. Guess what? I lost 2.4lbs!! This has not happened since before February! So, yep....right now I'm a firm believer that IIFYM works IMHO. YWLSMV (your weight loss success may vary - we all have different things that work for us).

    MFP was saying I would only lose .2lbs a week eating what IIFYM recommended and I'm following the reckless calorie amount!
