Hi everyone

Have left some questions I need answered under my last post EPA/DHA, I said on there I could not get onto the bodyfat/block calculator.

Well I can now and I'm more confused, I put my weight in as 510lb, my waist and height and wrist measurements. When I press calculate, the weight goes to 300lb and wont calculate my 510lb weight.

It comes up with 22 blocks per day of each Protein, Carbs, Fat, but do I need more than that as I am carrying more weight.

Also when they ask activity level, what would you class my activity, as I do Powerlifting with heavy weights mon, wed, fri, and do 60mins of staionary bike 30mins in the morning on wakeing and 30mins before I go to bed, I do this everyday of the week. Do I class this as heavy daily weights etc, just a bit confused as im new to the zone and want to get it right.

Also I have some questions regarding the Omega/rx which is on my other topic, if anyone can help with that would be great. xxxx

Hi robert!

Your stats fall outside those built into the calculator. In that situation, Barry recommends to assume 50% body fat. For you this would mean 255 pounds LBM would be used to calculate your protein/block requirement. Considering your stature and daily physical activity, you'd use an activity level of very active to elite (activity factor of either 0.9 or 1). The calculation is LBM times Activity Level factor equals grams of protein required daily. Divide this by 7 to obtain number of blocks (7 g protien per block). Following this method of assuming 50% fat would put your protein requirement in the range of 33 to 37 blocks per day. Because of the combination of your stature and your activity level, you may want to call the number at the top of this page to ask the Zone reps for clarification of you block amount.

Hi Sue

I contacted the number you suggested and they worked it out as 24 blocks per day, also they said to start on 5g omega/rx and work up to 7.5g per day.

This still seems not right to me as 24 blocks would be 225LBM times an activity level of 0.8 or less, but by all accounts my activity level is at the top, liffting very heavy weights three times a week and 60min cardio a day

Thanks again sue xx

hi robert,

You're welcome!

For starters, I misread your previous post and thought you'd been doing 60 min of lifting 3 days a week. But regardless, that wouldn't haev changed what I posted to you previously in this thread. This was my reasoning. I'd put your activity level at either active or very active. If we follow the info Barry gives in Zone books, for a person of your size, for the protein requirement calculation, we'd increase by one level over your actual activity level, because carrying the excess weight on yoru body is like doing strength training 24/7. This is how I arrived at suggesting you'd use either the Very Active or Elite level . The reason I suggested calling the Zone Labs reps is that, in your case, it amounts to a large number of blocks. Did they give you the details of how they arrived at 24 blocks? I'd be interested to know how to arrive at that amount. Possibly there are additional factors being taken into account that I'm unaware of, such as an overall maximum on blocks, or a cutoff highest LBM to assume, etc. One would have LBM in the high 180's to arrive at 24 blocks with your activity level, so, I'm puzzled. Please let us know if you learn more about it. Thanks!
