Estimating Bodyfat


It's that time of year again. Before setting my health and fitness goals for 2006, I decided to check the status of a few things first. One of these is my current level of bodyfat - last estimated back in April this year.

Once again I used the same technique as used by the US Department of Defense, the formula being :

% body fat = 86.010 x log10(abdomen - neck) - 70.041 x log10(height) + 36.76

Note that the formula is a little different for females :

% body fat = 163.205 x log10(waist + hip - neck) - 97.684 x log10(height) - 78.387

Plugging in measurements for abdomen, neck and height gave me :

%bf = 86.010 x log10 (35-16)-70.041 x log10(72) + 36.76 = 16.65617 (slightly better than last time).

For demonstration videos showing how the measurements should be taken, have a look at the Physical Readiness section of the NPC site.

Dietary Goals.The workout goals will be re-evaluated in a couple of weeks (12 weeks after starting), however there are a few dietary improvements I hope to make over the next couple of months. A number of changes have already been made, but to add to the list : Reduce alcohol consumption to 3 drinks per month Limit fried foods to 2 meals per week Limit consumption of red meat to 2 meals per week Reduce consumption of foods containing additives and preservatives Increase consumption of fruit/veg (the fruit is already quite reasonable, it's the lack of vegetation that I'm mainly looking to address) Reduce consumption of milk to under 3 pints per week (until quite recently I was drinking this amount daily) Eat more nuts and seeds The target date for the first four items is 1st July, with a deadline of 1st August for the remainder. Should be an interesting couple of months.


Of course, if you enjoyed these, I'd highly recommend grabbing the Strength & Fitness Newsletter. Delivered weekly, and absolutely free.

(there's also a Daily Update, if you're looking for an even larger dose of training-related goodness.)

NB : If you'd like to write a guest post for Straight to the Bar, or if you'd like to join the team of Moderators here (I love hearing about everyone's training approaches) - get in touch. And if you've got a fitness competition or seminar coming up, add it to the calendar.

Look forward to hearing from you.
