How I Lost 11 Pounds in 15 Days.

Here's the quick rundown if you're not into the whole shock value thing: I didn't get sick.  I lost 11 pounds in 15 days.  Of that, I estimate I lost around 7.3 pounds of fat and only about 1.1 pounds of lean mass over the 14 days of the quick diet.  Not bad for a cubicle dweller, eh?

And, no, I have no idea if these results would be typical if you were to try it.  But at a 1,300 calorie a day deficit or so, you're bound to see some scale movement.

By the Numbers - How I Lost 11 Pounds

The diet was based on Lyle McDonald's Rapid Fat Loss Handbook, modified to mesh with my wife's eating habits (OR you decide: another explanation is because I'm a wimp and I would have had to cut further in the fat/carbohydrate categories to follow it 100%).  In essence, I targeted around 1 gram per pound of lean mass daily, but I cheated a bit on the fat side when cooking.

(His manual is highly recommended, by the way - above all else it will help you understand diet design when doing a modified "Protein Sparing Modified Fast".  The is the third year I've done some form of it in the Spring.)

Here are the days by the numbers, with the re-feeding day on the 19th:

I took caliper body fat readings on the first day of low carbs, the 6th, and on the last, the 18th - I got 15.5% on 5/06 and 12% on 5/18... that's how I quoted the lean mass/fat poundage in the introduction.

I averaged consumption of 1,378.8 calories, 52.4 grams of carbohydrates, 55.7 grams of fat and 148.9 grams of protein a day. Because of that, this diet was a rousing success - I estimate I probably would keep my weight flat around the 2,600 to 2,700 calorie a day mark (read: I expected to lose around 5 real lbs).  I reduced my workout days from 3x a week to 2x a week during this span, and didn't do any cardio other than yard work, either - go figure.

A note: you can't really count that 185 lb day - one feature of reduced carbohydrate diets (really, anything below around 75-100g a day) is the massive drop in water weight in the beginning.  Dropping to 178.4 overnight obviously isn't sustainable - 6.6 lbs a day would mean I would weigh in the mid-90s at the end, on a 5'10" frame.  The real weight loss is reflected in the low carbohydrate days - 178.4 to 170.0.

What's Next?  What's Your Goal?

I plan on taking a few days off, then back to the grindstone (maybe even tomorrow - it might be a lean weekend!).  My final goal is to be in the single digit body fat percentages - somewhere under 166.7 pounds at 150 lbs of lean mass.  And, yeah, long time readers will note that I'm not using BMI - at 174 lb I'd be overweight (25.0 BMI) at 12% body fat... good joke!

Who said folks with a day job had to be in bad shape?
