I did what u said. Mult. Weight x bf = 4,350? Then, subtracted 4,350 (lbs. in fat?) by my weight of 145? (i don't think it can be subtracted the other WEIGH?) lol. It comes out 2 (4,205)? See.....something is wrong? 
My favorite Subjects R English and Art) ...Math is not one of them! He. he!

Therefore of your total body weight, your lean mass = 100%-29% = 71% To find 71% of a number you times it by 0.71 (which is 71/100). So your total weight is 145# right? So 71% of 145# is = 145 x 0.71 = 102.95 pounds So, your lean body mass is ~103 pounds. So, your protein requirements would be something between 100 and 150g per day. |

| So from the looks of it, one can find their LBM by 1st subtracting BF % by (100%)? That makes sense. I think i might b able 2 do this next time!! |
| i better head to the Health food store and stock up on some "Whey Protein" and for starters, add some Protein kick 2 my Smoothies? LOL. |

will start keeping track of my daily Protein for starters and make sure I get it from a good food source!

I have a formula I use to help me calculate this, but there are no 'truly' accurate ways - the best thing you can do is to monitor your weight and record what you eat. If you don't lose or gain then you have found your maintainence! |

| Emma, i would sure like to share with you my daily Calculations on this? How about if we start a Food Journal section where we can share (a daily recording) and get your take, so we can be lead in the right direction? |
