» Fat Loss Progress

Back in October I talked about my fat loss plan, which boiled down to this: exercise 30 minutes a week and live a 1.5 lb-per-week feedback diet.

Here's a snapshot of the graph on the sidebar:

The red dots are my daily weigh-in, the blue dots are my water jug body fat measurement (aka the days I go swimming). The green and blue lines are trend lines. I've lost about 25 pounds. There are some notable features here.

First, notice how my body fat was plummeting compared to my weight when I was actively swimming and doing some minimal strength training. I got out of the habit, and haven't really reestablished it yet. Also, note that the body fat measurement is consistently lower than the BMI number.

Second, notice that my trend is most consistent when I was swimming regularly. Seems like that exercise thing is a good thing to do.

Third, and you'll have to take my word for it on this, when I was following my feedback diet it worked flawlessly. The humps are when I got rebellious and didn't follow the diet even though the feedback said I should.

Let's review the diet. It's really really easy. Get a piece of graph paper and mark today's weight. Draw a line that goes down 1 lb every 5 days (this is the rate I chose, you may want to choose 1 lb per 7 days or whatever). Now, if your weight is over the line, you eat smaller portions, drink more water, and skip dessert. If it's under the line, you don't fret it. Eat what you want (without gorging yourself).

Ok, this works really good, but there's bound to be hiccups. You're only human. So when you get a hiccup like I had in January/February, the feedback system breaks down. It only takes a week or so of disobedience for you to be completely unable to get back down to the line you charted without a sharp dive. But a sharp dive is exactly the thing you are not prepared to do. So you continue to float too high. Maybe you start a new chart (a wholly demoralizing thing to have to do), and then another hiccup begins and you lose heart even sooner. What I'm getting at is that line is just too rigid. The whole point is a sustainable rate of loss.

So I modified the mechanism slightly, and hence this blog post (no, it's not so I can brag about losing 25 pounds—that comes when I get to my target weight).

Take a piece of graph paper and draw a line with the slope you want as before, starting in the corner. Now, that line starts 5 lb or so above where you are now. This is to emphasize that the line is only a slope reference, not the actual line. Now mark your weight every day, and then decide if it's a diet day or not. Do this by estimating with your pencil, finger, or just your eyes, what the slope of the line that best fits the last 5 measurements is. If it's pointing down as much or more than your reference slope, it's not a diet day. If it's flatter (or pointing up), then it is a diet day.

I've been trying this new system for a few weeks and I have found it much more adaptive and encouraging. If you have a bad couple of days, you can be back on track within a few days, no problem. You don't need to make a new graph. You can see the progress of the past and recognize that while it's not a perfect line it's still very good progress. All the good kinds of feedback.

So go give it a try. It can fit in with whatever other exercise/diet plan you have. It can work if you are just maintaining your perfect weight, or even if you're trying to gain weight. It's easy (just a piece of graph paper on the fridge). You've got nothing to lose. At least, nothing you don't want to lose.

» Going Gluten and Casein Free: The first couple days.

My wife and I decided to try the diet with our son and see if it would improve his behavior positively.  Unlike medicating him, a diet is easily reversible if necessary, and doesn’t have any adverse effects overall.  Of course, it means looking for the right resources, and has far reaching implications if it turns out his behavior is caused or aggravated by gluten or casein.  So, we thought we would try out the alternatives.  

For Gluten, we purchased some Gluten Free/Casein Free flour from our local grocery store.  Smiths, Albertsons, and Harmons all had this same flour, all for about $5.00 a pound.  It’s expensive, but for a trial it is worth it.  We also purchased (from the same makers) some gluten/casein free brownie mix, polenta, and chocolate chip cookie mix. 

The first one we tried was the brownies.  They were easy to mix, and the batter tasted the same.  The only thing I didn’t add to it was the recommended vanilla, but other than that all was mixed according to the instructions.  Once finished, I spread it out in a pan, and baked according to directions.  

I was amazed!  They came out very moist, and have retained that moisture far longer than other brownies I have ever made.  More cake-like than the traditional gooey brownie you may think of, it’s been quite impressive.  I was sold, and my son ate it with relish (and he doesn’t normally eat anything but icing on cake-like products).  It’s still too early to tell, but I think we had a hit with these brownies.  

Next, dealing without milk.  Casein is one of the primary milk proteins, making any milk-based product a problem.  And a huge problem, as my son has almost an addiction to cottage cheese (though that may make sense if it’s becoming an opiate in his system).  So, how to break him of his milk kick? 

I started with the replacement milks:  soy and rice.  Now, I’m not a big fan of soy based products.  Soy is another food high on the food allergy list, and it’s not something I wanted to try on Jonathan at such an early age.  So, I tested it myself.  

The soy milk we purchased was a small one quart carton of Silk, which was calcium fortified.  I poured a small amount in a cup and tasted it:  it was really sweet and surprisingly good!  I gave some to Jonathan, and he drank it, and took more.  A small victory, and no side effects.  

Next, I tried the rice milk.  We could only find a two quart carton, so we purchased that.  I poured it out, taking a small taste.  It paled in comparison to the soy milk.  It had less flavor out of the carton, and seemed more watered down.  I tried it on Jonathan, and he took a taste and poured it out on the floor.  Well, the verdict was out, he didn’t like it.  But I may try it again on him in another form, because he did try it just after tasting the Soy milk.  

So, that has been our experience so far.  As it stands, the conversion hasn’t been too difficult with Jonathan eating more fruits and almost no cheese (just need to continue to remind the in-laws of the new diet), and his behavior has improved noticeably.  We are cautiously optimistic on this front.

The Fugue :
» The Hacker's Diet

I came across this blog post while googling an unrelated gnuplot problem, of all things. The post talks about The Hacker's Diet. Duly intrigued, I whipped out my razor and plowed through the book. I like it.

The book is well-written, doesn't take itself too seriously, takes the subject matter seriously, and takes the audience seriously, i.e. you aren't expected to be Superman—the program is very down-to-earth and achievable. It is slightly aged (he mentions at one point that you need a color monitor to really appreciate the color graphs), but this isn't a problem.

The best part about the book (besides being free) is that he takes the problem of weight loss and attacks it as an engineering problem. He comes up with an understanding and a plan and implements it, and loses some 70 pounds. This book definitely appeals to every inner geek.

The worst part about the book is that his solution involves calorie counting. That makes me sick on so many levels, but I'll just rant on two of them. First of all, a calorie is not a calorie. I don't know if this is new knowledge or not, but we see it in all the latest fad diets. Atkins, GI, etc. are all based on the fact that a calorie is not a calorie. Second, I am not going to spend my life counting calories, thank you very much. I'd rather drink oil.

Speaking of drinking oil, this book has a very interesting parallel to the Shangri-La diet. They both use the thermostat analogy, but Shangri-La aims to adjust your off-kilter internal thermostat and this book aims to replace your broken thermostat with record keeping and conscious decision. Certainly, one could apply both at the same time.

In spite of me not wanting to count calories, I do intend to put a modified version of this plan into practice. Since I don't want to count calories, I am going to have to rely on some other feedback. Since most of us eat a relatively manageable variety of foods, we should be able to get an instinctive feel for "how much" we are consuming on a meal-by-meal and/or day-by-day basis. Indeed, he talks about getting to this point, by accident. I intend to get there much sooner, on purpose. By keeping a food log and comparing it to weight loss/gain over the period of a month or two or three, and studying it in hindsight, I should be able to get a feel for three "thermostat settings": lose weight, maintain weight, gain weight. It may be a bang-bang approach, but there's also the minute automatic adjustments and body's metabolism adjustment working in your favor while trying to stay stable.

I have adjusted my weight graph to include a trend plot as described in the book. While I was at it, I added the plot for measured body fat percentage (which I need to start doing more frequently). BMI is a linear relationship with weight, so the kg on the left correspond with the BMI on the right. So, by graphing measured body fat percentage you can see whether I am above/below the BMI for my given weight, plus see that otherwise invisble chasm between losing fat and losing weight. If you'd like to set up your own such graphs, I'm happy to share my code with you. Just drop me a line.
