So I did some calculations today based upon my DEXA scan. Without getting into the boring details of the math, I figured out that for every 1% of bodyfat that I need to lose, that equates to 1.85lbs of fat. So if I'm at 12.9% now, and I'm wanting to lose 4% more, that would put me at 8.9% which would equal 7.4lbs of fat total.
There's 3,500 calories in a pound of fat, so 7.4 lbs x 3,500 cal = 25,900 calories. So I will need to burn an extra 25,900 calories while keeping my daily calorie intake right around my maintenance level of 1,800 calories per day in order for me to achieve my goal.
So then I decided to figure out how much cardio I'd have to do to burn that off. Honestly, I hate cardio, so realistically I'm never going to do more than 30 minutes of steady state cardio, which usually ends up being 300 calories per session. So if you divide 25,900 calories by 300 calories per session, it comes out to be 86 days straight of cardio, which is almost three solid months. Wow, that's sort of an eye-opener. I've been doing some walks and other random activities besides weight training, but these numbers tell me that I will have to get serious about expending extra energy if I'm going to reach my goal by the mid-July timeframe.
