Diet Hack, Week 4


This is Day 29 of the Garrett Diet Hack.

Target Weight: 199.4 lbs
Actual Weight: 192.6 lbs
Food budget: 108.8 oz
Weight loss so far: 7.2 pounds

Norovirus: An unpleasant weight loss program.

You will notice a sharp drop in the chart on the right for the past two days. I lost two pounds in one evening due to the extremely unpleasant Norovirus that has been circulating in our area. First my grandmother got it, then my two daughters, and then me. I will spare you the gory details, but let's just say that I do not recommend this as a weight loss program. I suspect that I will bounce back up to around 194 when I rehydrate.

Other than this unpleasantness, the Garrett Diet Hack has been proceeding smoothly. I have dropped so far below my target that I have actually stopped weighing my food.

Based on the first three weeks of weighing all my food, I know this: On a day when I try hard to keep my food intake down, I eat about 40 ounces. On a day of gluttony, I eat about 65 ounces. My biggest day was 68.8 ounces, when I had a few beers after work.

For the past week, my allowed food budget has been over 80 ounces almost every day. There is not much point in weighing my food, when it is almost impossible for me to eat that much food in one day.

I should point out that a "day of gluttony" is not what it used to be. I have gotten in the habit of eating less than I used to. The biggest thing that this diet hack has taught me is how to monitor the amount that I eat. I recognize what "A Lot of Food" looks like. I look at the typical restaurant portion now, and I see two or three meals. My wife and I now split meals because I simply can't eat it all anymore.

I think when my weight hits about 185, I will start bumping up against the limits again and will need to start weighing my food. In the meantime, I will continue to lose weight by "habit."

Faith: Metablog


I decided recently that I would start blogging about my faith for Lent. This sounded like a great idea until I got ready to do it. It's actually pretty frightening. Blogging about faith is like getting a tattoo of a cross. It is very permanent, very public, and it is guaranteed to make people think differently about you.

Depending on how I do it, a blog about faith and religion could be just a small step from standing on a box on a college campus. At Florida State in the early 90s (and probably still today), this job was usually performed by Brother Jed. Brother Jed was the stereotypical street preacher. With floppy bible in hand, he would shout out to everyone who walked by, whether they wanted to hear him or not. He insulted people, stirred up crowds of hecklers, and scared thousands of people away from anything related to Jesus. I would usually stop for some great free entertainment whenever Brother Jed was in town. By the sheer number of people he has shouted at, he may have chalked up some successful conversions, but I suspect the net result of his work has been a loss for Christianity.

A more subtle approach used on campus was that of the Campus Crusade for Christ. Instead of standing on boxes, members trolled the campus for people who seemed like they were in a good mood and open to some conversation. I must have looked pretty harmless, because I got approached quite a bit. They would walk up to me and introduce themselves, often in a too-friendly manner that reminded me of used car salesmen and infomercials. From there, we would sometimes participate in a few hours of intellectual sparring that left the Crusader exhausted, and myself in an even better mood than when we began.

Well-meaning friends spent years trying to convince me of their faith. Some friends shared books with me, but with their mostly faulty logic, most of those authors only sharpened my arguments against faith.

Years later, when I did become a Christian (through the help of many more well-meaning friends), I realized that there are some crucial pieces missing in the arguments that I had fought so hard against. I realized the following:
  1. No one can be converted to any religion by another person. We are too smart for that. We "know" too much. We can only convert ourselves by making a decision to believe, based on a limited understanding of what we are believing in.
  2. There are some things that we don't really understand until we experience them. Roller coasters, beautiful views, raising kids, starting a business, falling in love, or great music are some examples. Imagine someone trying to argue with you about the beauty of a certain song you hadn't heard, or that a specific person you have never met is destined to be your true love!
So, don't worry, I'm not going to try to convert you. I can't.

I am just going to share my experiences and my own understanding, in the same way that I might share any other life changing experience. In the process, you may come to know me better, and gain some understanding about how a staunch, rational atheist can become a Christian.

Diet Hack, Week 2


This is Week 2 of the Garrett Diet Hack.

Target: 201.4 lbs
Body Weight: 199.0 lbs
Food Budget: 38.4 ounces
Weight Loss so Far: 0.8 lbs

The Effect of Travel

Wow, look at that graph. Things were going along quite smoothly until late last week. As you can see, my weight started to swing wildly up and down. The reason is that I have been traveling.

Travel results in the following three things happening to my body:

  1. Dehydration. The air on an airplane is extremely dry. Even though I drank quite a bit of water, I still got dehydrated. I noticed that my weight dropped way down on both of the days after I had flown. I set a new record low yesterday (after flying) and then gained 2.6 pounds in one day! I didn't realize this was due to dehydration at first, so I happily ate up to my alloted budget on those days, thinking I had lost a bunch of weight all the sudden. When I rehydrated and ate a bunch of low-fiber food to boot, that led to weight gain and...
  2. Constipation. I'll spare you the details. You know how it is when you travel...
  3. Lack of exercise. Almost all data points until now have been taken after a nice five mile jog. Granted, the weight loss due to the jog is mostly water, but even so it affects the baseline measurement. When I don't jog for a few days I probably put on a few ounces. And a few ounces at this point will definitely show up.
All this leads to a net WEIGHT GAIN for the week. Zoinks! Time for some good ol' Lenten suffering and discipline. And fiber. Lots of fiber.

Diet Hack, Week 1


This is Day 8 of the Garrett Diet Hack Experiment.

Target: 202.4 lbs
Body Weight: 198.4 lbs
Budget: 64.0 oz
Food eaten: 46.25 oz
Target weight loss so far: 1.0 lbs
Actual weight loss so far: 1.4 lbs

The Week in Review

This week began the Garrett Diet Hack experiment. In the first week, I have lost 1.4 pounds, so I am ahead of schedule. As you can see on the graph, the trend of my weight is steeper than my target weight. Here is what I have learned so far:

  • Being hungry isn't that big a deal. My body adjusts quickly to changes in the level of food consumption.
  • Fiber is super important.
  • The value of this diet, more than anything, is psychological. First, because it is based on the laws of physics, I am guaranteed to lose weight. That gives me motivation to continue on the regimen, no matter how uncomfortable it might get. Second, I see instant results. Even though my weight fluctuates naturally, over just a few days I started seeing a downward trend. The trick is to use an accurate scale and track my weight so that I can see that trend more clearly. Third, the very act of weighing everything I eat makes me be very deliberate about what I am putting into my mouth. I am eating much smaller portions, snacking healthily, drinking less, and eat tiny portions of dessert. Finally, the diet motivates me to exercise in the morning before weighing myself.

Lent and Fasting

Today is Ash Wednesday, which is the first day of the Christian season of Lent. In the Episcopal church, this is one of the two days of the church year where fasting is suggested. This also marks the beginning of the time when many people "give up" something for Lent. For forty days they may give up chocolate, beer, or some other indulgence. Instead of giving up something, many people will add something, such as meditation, special prayer time, or study.

I was interested in fasting today because, after all, the Garrett Diet Hack is a kind of gradual fasting program. I thought it would be interesting to just give up food altogether for a day to see what would happen to my weight. It would be another interesting data point.

So, I sent an email to my pastor asking her what fasting is all about. She replied that the principle point of fasting is to draw closer to God. The experience should be a reminder of Jesus' sacrifice for us. The experience should teach us something about ourselves and our relationship with God.

In thinking about her reply, I realized two things. First, if I were to fast today I would be doing so for the wrong reason. Gathering an interesting data point for my diet hack won't draw me closer to God. Second, I realized that, as a whole, this diet program will draw me closer to God during the whole Lenten season. I will be fasting in small doses every day of Lent. As I get closer to Easter, my target weight will drop down to levels that will be difficult to achieve without giving up most of the foods and drinks I enjoy. In the process I will become healthier, and God is certainly pleased when we take good care of our bodies.

Then I thought of other things that would draw me closer to God this Lent. I decided to start sharing my own faith journey. I considered myself an atheist about nine years ago. I remember telling my wife that nothing would be able to convince me that there was a God. Given that I am a Christian now, a lot must have changed in my thinking about religion and faith. I will start sharing some of my experiences over the next few weeks.

Diet Hack, Day 6


This is Day 6 of the Garrett Diet Hack Experiment.

Regularity Ensues

Target: 202.7 lbs
Body Weight: 197.8 lbs

Food budget: 78.2 oz

Food eaten: 42.4 oz


Woo hoo! Looks like fiber is going to be a major part of this diet. I lost 2.4 pounds in one day.

In addition to the Metamucil taking action yesterday, this was also helped by a jog in the morning before I weighed myself. I lose about 0.8 pounds by jogging five miles, even including the water I drink before the jog. That weight loss itself is mostly water, but it still counts in this diet. I didn't jog on days 4 and 5, so this affected the daily weigh-in.

You'll notice that now the trend line is steeper than the target. That means I am losing weight faster than I need to. It's amazing how only one data point can change things so much.


Hunger

I am trying to get a head start on the later weeks of the diet, when it will be more difficult to lose weight. So I have been trying to eat less than my allotted budget. I have noticed that I am hungry more often. But interestingly, I also don't mind hunger as much. In only a few days, my body has started getting used to the idea of being a little hungry.

We were in a rush this morning, and I didn't get a chance to eat breakfast. Normally I would have been starving and irritable by lunchtime. Today I was certainly hungry, but it didn't make me irritable, and I didn't feel like devouring food as soon as I saw it.

Even with a beer at lunchtime, I only ate 42.4 ounces of food today. The diet gave me the option of eating 78.2 ounces, but I didn't feel like I needed it. Plus, the big drop in my weight was a strong encouragement to keep my food intake down.

Diet Hack, Day 5


Danger! Danger!

Target: 202.8 lbs
Actual: 200.2 lbs

Food Budget: 42.1 oz

This is a problem. Today's graph shows my weight trend going UP! Exactly the opposite of what I want!

However, I did have several nice healthy bowel movements after weighing myself. Looks like the Metamucil is kicking in. We'll see what that does to my weight tomorrow.

Diet Hack, Day 4

This is Day 4 of the Garrett Diet Hack Experiment.

Day 4

Target: 203.0 lbs
Body Weight: 199.8 lbs
Food Budget: 50.7 oz

I started to get worried when I created the chart on the right. You'll notice that the trend line of my actual weight is heading toward convergence with the target. That worried me, because it means that my daily food budget is going to start to shrink quite a bit as that gap shrinks.

Here's where my blog will take a necessary turn toward crudeness and "too much information." You see, I had become somewhat constipated on days 2 and 3, in spite of making sure I am getting fiber in my diet to prevent this very thing from happening.

For help I turned to the old standby for this very problem: Metamucil. Metamucil is basically just a high fiber source with a scary name that makes you feel eighty years old when you take it.

Diet Hack, Day 3

This is Day 3 of the Garrett Diet Hack Experiment.

Target: 203.1 lbs
Actual Weight: 199.6 lbs
Food budget: 56.2 oz
Food eaten: 49.63 oz

Dilemma Trumped

Yesterday I outlined my dilemma about going to the Magnolia Grill and gathering data for the Diet Hack Experiment. Well, this morning we realized that the awards ceremony for our daughter's science fair had snuck up on us. The presentation was this evening, exactly when we were supposed to be sitting down to dinner at one of our favorite restaurants.

Ariane worked very hard on her project, and had done a superb job. The goal of her project was to determine which soaps are the most effective antibacterial agents. She conceived of the experiment, and figured out all the proper controls, bugged us to get her the materials, and then spent hours organizing and analyzing her results. We knew she had a good chance of getting an award.

When we realized that we had scheduled dinner on top of the awards ceremony, we were faced with a new dilemma, much more important than whether to bring a scale to the restaurant. Unquestionably, the right thing to do was to go to the science fair. However, it is "hard" to tell adults you have to reschedule, and "easy" to tell your child that you can't make it to the presentation. We made the correct decision to reschedule the dinner. Teresa's boss was very supportive.

How many times do we take the easy route! We are faced with decisions like this all the time. We miss out on important events in our lives because small things get in our way. Sometimes those small things are really just minor obstacles that are inconvenient to move out of the way. I am so thankful that we had the proper perspective this morning.

So, today was a great day on all fronts. My weight dropped down a bit, and I didn't have any trouble keeping on target. I got to have a piece of Valentine's candy from yesterday.

But best of all, and most importantly, I was there when Ariane got third place for her science fair project.

Diet Hack, Day 2

This is Day 2 of the Garrett Diet Hack Experiment. See my earlier post for an explanation.

Adjustment in the plan


When doing experiments on your own body, it always helps to have a biochemist to consult with. Fortunately I live with one. My wife Teresa suggested that instead of reducing the target weight by one pound at the beginning of each week, I gradually reduce it. That way I won't have a "starvation Monday" effect. I've never been a big fan of starvation, so I think this is a good idea. I plugged the numbers into Excel and came up with daily target weights. So from now on you will see a target that drops slightly each day.

Today's Target: 203.3 lbs
Actual Weight: 200.0 lbs
Food Budget: 52.1 oz
Food Eaten: 53.25 oz

Oops!

The astute reader will note that I went over my budget by over an ounce today! I think this happened because of an addition error. I will need to be more careful in my final meal of the day. I also didn't write down the food budget on my index card, so that threw me off.

I had two glasses of wine with dinner. If I had to do it over again, I would have cut out the second glass of wine, and had a piece of Valentine's chocolate instead.

Tomorrow's Dilemma

Tomorrow night we are going to one of the top restaurants in the country: The Magnolia Grill in Durham. It is soooo good.

So what should I do? Take my kitchen scale with me? Just splurge and forget about it?

Some factors that weigh in my decision:
  • This is a very nice restaurant. Taking out a scale is sure to draw the attention of everybody in the room.
  • We are having dinner with a bunch of biochemists. Pulling out a kitchen scale and explaining this experiment would provide a great conversational background for the evening.
  • Teresa has sternly warned me not to bring the scale into the restaurant.
Some possible solutions:
  • Teresa suggests that I weigh myself before and after eating there. Assuming I don't drink any water or go to the bathroom, this would at least give me the data point that I need for the experiment.
  • Forget about the diet hack for an evening. Just splurge and go crazy with the whole meal. In this case I will pay the price the next few days, when my body has stored all that good food into fat, and I have to eat less to recover.
  • Eat the absolute minimum during the day (we're talking hard tack and beef jerky) so that I can still stay under budget.
  • Bring the scale, risking matrimonial disharmony.
Tune in tomorrow to find out what I decided to do...

Diet Hack, Day One

Target: 203.4 lbs
Weight: 199.8 lbs
Food/Drink budget: 57.6 oz
Actual food/drink eaten: 47.75 oz

Burritos are Heavy

(For an overview of the Garrett Diet Hack, see my previous post)

I went to QDoba today for lunch. QDoba is a great Tex-Mex fast food place with really fresh food. They have delicious burritos. The only problem is, that it turns out that those delicious burritos not only look big, they are also pretty heavy. My burrito weighed in at a hefty 20 ounces. That's more than one third of my budget!

I knew I was going out for dinner so I didn't snack all afternoon. I was really, really hungry by dinner time. In my weakened state I miscalculated how much more I could eat. I thought I had 24 ounces of food left in my budget, when I actually had 28. That's a pretty big difference when one burrito weighs 20 ounces.

At Macaroni Grill I was able to have one glass of wine, a caesar salad, and half of my entree. 19.25 ounces total. Because of my miscalculation, I finished the day with only 47.75 ounces of food and drink taken in. Ten ounces under budget! I need to learn to eat more.

The Garrett Diet Hack



Sometime in my senior year in college, my weight topped 190 pounds, and I never looked back. At just over 200 pounds, I am not terribly overweight, but I would certainly like to get rid of the extra belly. If you have ever dieted, you surely know that losing the last ten pounds is the most difficult.

A few weeks ago I had an idea for a simple diet technique that is based on the fundamental laws of nature. As far as I know, it hasn't been tried yet, so I am calling it the Garrett Diet Hack until someone shows me it has already been done. It is a "Diet Hack" because it isn't a diet per se, where I tell you what you should eat. This is more a life hack than a diet. We all know what we should and shouldn't eat.

Potato chips = Bad.
Spinach = Good.

You don't need me to tell you that! But I bet you eat more potato chips than spinach. I don't care what you eat. If you follow this technique you MUST lose weight. You can combine this Diet Hack with any other diet to enhance that diet's effects.

Laws of Conservation

Let's start with why it works, and then move on to how it works.

In physics and chemistry, the law of conservation of mass states that, in a closed system, mass can neither be created nor destroyed. Likewise, the law of conservation of energy states that energy can neither be created nor destroyed. The only exceptions are nuclear reactions, which certainly do not take place in your body. (Even if you eat "nuclear" chicken wings.) If your body were a "closed system" then you would never gain or lose any weight.

However, your body is not a closed system. You eat food or drink liquids, taking in mass and energy. You lose mass by sweating, breathing out carbon dioxide, urinating, and defecating. You lose energy constantly as your body burns the food you have taken in. The amount of energy you lose depends on how active you are.

When we say that we "take in energy," what we really mean is that we are taking in food that has chemical energy to be burned into something with lower chemical energy. Sometimes people will say that a certain number of calories is "equivalent to" a certain number of pounds in your body, but this is misleading. Your body cannot convert energy directly into mass. What your body really does is take one high-energy chemical, like sugar, and convert it into a mixture of other chemicals, like proteins, fat, and carbon dioxide. No matter what it converts the sugar into, the mass of the chemicals it has produced will always be equal to the starting chemicals.

When you gain weight, you have taken in a certain mass of food that your body doesn't need at the time. Your body stores that food for later use, mostly in the form of fat. When you lose weight, your body is reaching back into that store to compensate for a reduced amount of energy-rich food taken in.

On to the Diet Hack...

How does this relate to dieting? Let's say you weigh 200 pounds. If you eat 2 pounds of food, then you cannot, according to the laws of physics, gain more than two pounds. You will weigh 202 pounds.

Fasting

If instead of eating 2 pounds, you fast all day, then by the next day you will have lost some weight. Your body MUST burn some energy to keep you alive, and that energy MUST come from stored chemicals in your body. Your body MUST keep breathing and burning some of your stored fat, in the process releasing carbon dioxide, and making you lighter. The fundamental laws of the universe guarantee that you will lose weight if you fast!

Alas, if only it were that simple. Fasting is one of the worst ways to lose weight, because your body simply bounces back as soon as you eat again. You will be extra hungry the following day, so you will eat extra food. Your body is also "accustomed to" being at that weight, and will work harder to store the food that you do eat.

However, let's stick to the fasting example for a minute. Let's say you weigh 200 pounds, you fast for a day, and on the second day you have lost 2 pounds. Now you weigh 198 pounds. If you were to eat only one pound of food, then you would weigh 199 pounds. That one pound of food could be ANYTHING. It could be a pound cake. You would still only weigh 199 pounds. You would have lost one pound.

Gradual Weight Loss

This diet hack is a more gradual extension of the fasting example. We start with a target weight. The target weight will be slightly above your actual body weight, and it is based on the foods that you are currently eating at the start of the diet. If you weigh 200 pounds now, and you typically eat three pounds of food per day, then your starting target weight would be 203 pounds. Each morning you subtract your weight from 203, and that is how much food you can eat.

Amount of food you can eat today = Target Weight - Actual Weight Today

The target weight is reduced by one pound per week. So, continuing the example above, the second week's target will be 202 pounds. If you still weigh 200 pounds at the end of the first week, now you can only eat two pounds of food. You "could" compensate by eating two pounds of high energy food, but you will only be cheating yourself, because the following week will only be harder when your target is 201 pounds.

Although your target weight changes once a week, the amount of food you can eat will change every day. Based on your weight in the morning, you are allowed to eat a certain amount of weight in food. You will notice right away if something you ate yesterday has caused you to retain weight.

EVERYTHING that you ingest that has calories in it must be counted to make this work. You can drink as much zero-calorie liquids as you want, and you don't need to measure them. Even though you temporarily gain weight when you drink water, it passes right through your body, so we're not going to worry about it. But everything else must be counted. Desserts, snacks, healthy and unhealthy foods, juice, lettuce, alcoholic beverages, all must be weighed and counted.

This is different from most other diets that say you should never weigh your self more than once a week or once a month. With this technique, I advocate weighing yourself every day. You will get instant gratification for everything you do. Going for a jog before you weigh yourself will show up immediately. Eating lots of fiber will mean that you stay regular and "lose weight" through bowel movements.

The first victim

To my knowledge, this hack has never been tested. I will be the first guinea pig. I suspect it may be psychologically difficult, so you will get to see me suffer (or not) and decide whether this might work for you.

Materials

I am a big believer in simplicity leading to success. The more complicated a diet (or any other program) is, the less likely I am to follow it. The required materials for this diet hack are:
  • A high quality bathroom scale with a digital readout
  • A high quality kitchen scale, also with a digital readout, for weighing food.
  • Index cards for writing down your weight and targets
I will also be monitoring everything closely on an Excel spreadsheet, but you don't need to do that. The above materials are all you need.

Step 1: Determining My Target Weight

For the past three days, I have been weighing myself to determine a target weight.

Here's the data I have gathered so far:







DateBody WeightWeight of All Food and Drink
February 10202.4 lbs50.5 ounces (3 pounds 2.5 ounces)
February 11200.6 lbs38.5 ounces (2 pounds 6.5 ounces)
February 12198.8 lbs46.5 ounces (2 pounds 14.5 ounces)


Interesting! I haven't even started the diet yet, and I am already losing weight! I have already discovered that the very act of weighing food makes me think about what I am putting into my body. In the past three days, before even starting the diet, I have cut back on alcoholic beverages (a beer is a very "expensive" 12 ounces), and I am drinking more water and eating more fiber. I also am very motivated to exercise before I weigh myself in the morning, because running five miles makes me drop about 1.2 pounds.

I will take the average of the three days for both numbers:

Average weight: 200.6 pounds
Average food and drink: 45 ounces (2.8 pounds)

So, my starting target weight for the first week is:

200.6 + 2.8 = 203.4 pounds

Starting this week, I will never weigh more than 203.4 pounds!

I will do this for eleven weeks, dropping the target by a pound a week. Then I will assess if I want to lose any more. Thirteen years ago, when I was last 190 pounds, I was also less muscular than I am now, so I may not want to lose anything beyond that. But we'll see.

What will happen in the coming weeks? Will I go crazy? Will I be stuck eating four ounces of food per day for ten weeks? Will I have to fast when I get bloated or constipated and don't lose any weight in a day?

I'm going to do it no matter what! My pain will be your entertainment.

Let the experiment begin...
