How's the diet going?

So, how's my diet been since I last posted forever ago? Did I stick with it? Have I gained the weight back? Can I stick to my own advice?

Well, see for yourself!



On December 18th, I weighed in at 167.3 lbs., an insignificant 0.3 pounds shy of my target weight. Woo hoo!

So, what's happened since then? What's the deal with all the calorie and weight spikes, and why is my weight trending upwards? Simple: After a well-deserved break, I'm back on track and building muscle now!

Instead of dieting to lose weight now, I've shifted my goal to complement my workout routine. As I still feel like I need to lower my body fat percentage somewhat to achieve the body type I want, I'm still aiming to eat only 2200 calories per day. It's been a little tough I'll admit (look at the calorie bank!) as my body wants to go back full-force to it's old eating habits, but I've managed to keep my net calorie intake around my target.

Christmas break, just after finishing the first phase of my diet plan, was the toughest as there were a bunch of parties to attend and food to be eaten. While it's important to stick to your plan, I felt that I deserved a break after losing 40 pounds over the semester (remember, I started dieting before I started using DietPower). I was careful not to completely lose control, though!

In any case, I feel like I'm right on track with where I need to be for my dieting. I'm losing fat (albeit much less) again, and building muscle at the same time.

I admit, I feel great not only just because I lost all that weight, but also because I've managed to accomplish something that so many people have a hard time doing. It's wonderful, being able to pass by magazines that advertise "Lose 40 pounds!" and think to myself, "Been there, done that!"

It's wonderful!

So how's my diet going?

Well, I'm glad you asked! Have a look:




In short, absolutely great! I now weigh less than I have weighed since high school! I really can't wait to be finished, though, and start working out and building muscle :)

So far, this diet has definitely been worth it!

How do scientiss measure the calorie content of food?

I've always been interested in the answer to this question, but I had never really searched for it until now. I found some notes from a university lecture by Dr. Samir Bali, Associate Professor of Physics at Miami University. I take no credit for the following text!

Q: How do scientists measure the calorie content of food?

A: Physicists measure the energy content of food by burning the food. To a physicist, a calorie is the heat flow needed to raise the temperature of one gram of water by one degree Celsius. To measure the calorie content of food accurately, scientists use a “bomb calorimeter”. The food sample to be measured is dried and ground into a powder (important point – all water content eliminated). Then it is placed into the bomb calorimeter, a strong metal container surrounded by a water bath. The metal container is pumped full of pure oxygen at 30 atmospheres pressure and the food is ignited. The resulting energy release is fast and violent, just like a bomb. The steel container holds in the explosion. Pure oxygen promotes combustion, and high-pressure oxygen greatly enhances combustion. All of the burnable parts of the dried and powdered food will burn in a calorimeter, leaving just a touch of ash. The calorimeter turns the energy stored in the food into heat flow. The temperature increase of the water and metal of the calorimeter reveals how many calories the food contained.

Q: How many calories does a candy bar have???

A: We saw in class that one food calorie (i.e., Calorie!) equals 1000 calories, which converts to 4200 joules. One joule of energy will lift a tenth of a kilogram one meter in the air. So one Calorie or 4200 joules will lift a 70 kilogram (155 pound) person six meters into the air. Calorimetry reveals that a Milky Way® candy bar contains more energy than a stick of dynamite. The candy bar contains 200 food Calories. That's 200,000 physicist calories or about 840,000 joules! Nearly a megajoule! A megajoule of energy from a candybar can perform enough work to lift an average 70-kilogram human being 1200 meters in the air. That's higher than the cliff face of Yosemite's El Capitan. No stick of dynamite can do that! In fact,an ounce of dynamite produces only one-quarter as many calories when it explodes as an ounce of sugar does when it burns.

Of course, the body cannot convert all of the energy from one candybar into work. A lot of the energy goes into heat, and some of the work goes into digestion. Overall, less than 20 percent of the energy contained in food can be converted into work. (So don't try to climb El Capitan armed with only one candybar.)

Aside: Some countries that use the metric system have completely abandoned the Calorie as a measure of food energy. In Australia, for example, diet soda sports the label "Low joule Cola." In the United States advertisers can claim a can of diet soda has "less than one Calorie." In Australia the equivalent statement just doesn't sound as impressive: "less than 5000 joules." On the other hand, candy advertisements in Australia can say that you'll "get a megajoule jolt from our candybar!"

10 Tips for Starting Your Diet

If you've checked out the images for this post, I'll have to add in a little disclaimer: I'm not new to dieting. I've given it a shot several times in the past couple of years. I'm not new to health and fitness or the world of nutrition. Before I felt I needed to diet, I felt I needed to build muscle, and did my fair share of research in the world of nutrition. I'm also not new to DietPower, the application I use to keep track of my dieting progress, and the application that generates the readouts given in this post.

What I am new to is sticking with my diet! I've finally figured out why, and I'm gonna tell you.

#1: Keep it simple. One of the biggest reasons I failed at my past attempts at diet in the past is that they were too complicated. My first attempt at starting a consistent diet consisted of me doing about a week of research and preparation, making sure I had all my facts straight, lest I should make some fatal error and end up realizing I've wasted time months down the road -- My perfectionism was my downfall. I not only tracked calories, but protein, saturated and unsaturated fat, sugars, fiber, vitamin, iron, cholesterol, phosphorus and folic acid. Bad idea. What I ended up doing was skipping one part of my recording process and then thinking, "Man, I'm so bad at keeping track of all this stuff... I'm just going to forget about it for the rest of the day." Eventually this would turn into "...I'll just forget about it for the rest of the week," and my diet would effectively fall into ruin. The bottom line: If you are simply interested in losing weight, focus on calories, and just keep an eye on your protein/fat/carb percentages.

#2: Don't be afraid to estimate. A corollary to my first point, some people are compelled to keep detailed records of every aspect, trying to be as precise as possible. I say, get rid of this habit as early as possible! You should certainly try and be reasonably accurate, using known figures when available, but when it's time to guess portions without a measuring cup and a scale handy, you're going to have to use your estimation skills a little bit. Know what a cup of vegetables and 3 ounces of chicken breast looks like and guess from there. Remember and write down what foods you eat, and look them up afterwards on a nutritional website such as NutritionData.com (a personal favorite). If you are guessing objectively, a daily net difference of +/- 200 calories isn't going to make a large difference in the short term, and should even balance itself out over time -- Which brings me to my next point:

#3: Plan for the long-term. As a rule of thumb, aim to lose no more than 2 lbs./week. This is not a target amount or a minimum, this is a maximum. Also remember that 1 lb. of fat is approximately 3500 calories. There are pleny of calculators that will tell you your BMR (basal metabolic rate) and help you estimate your net metabolic rate. For the average college age man, this should be around 3,000 calories a day, more if you have a fairly active lifestyle.

For example, according to this BMR calculator my BMR is right around 2000 calories exactly, +/- 50 or so. I also know, from the data DietPower has gathered from me, that I expend a total of 3269 calories per day, as of today. This means that I am losing 1269 calories per day, assuming I eat only enough to compensate my BMR. 2 lbs./week would mean a 7000 calorie deficit per week, which means that I should aim to have a net deficit of 1000 calories per day. This means I can eat up to 2269 calories per day and still lose 2 lbs./week.

For planning and recording purposes, I highly recommend DietPower, which I've mentioned several times already. It comes with a nutritional database containing thousands of foods and is relatively simple to use.

#4: Set realistic goals. Instead of determining to wake up the next morning, run a mile, stretch, and eat health foods every day from then on, start with one individual goal and incorporate that into your life. I highly recommend starting with changing your eating habits first -- you will start to feel the benefits from healthier eating within the week, even if you're simply skipping out on a couple of those donuts or some of those coke cans (notice I said some, not all ;). Then begin to incorporate exercise a couple weeks down the road.

For the long term, figure out how many weeks it will take you to reach your target weight. If possible, get a professional to give you an accurate body fat percentage measurement. Then, ask the staff at the local gym how you can figure out a reasonable target weight. For those of you who (like me) would rather look it up online, you can find a good guide here. If you set your goals too high, you won't reach them. Set an easy goal for yourself and, if you feel as though you can sacrifice more later on, do so.

#5: Get into the habit of recording what you eat. Don't rely on your memory as an accurate record as to what you've eaten and how many calories you've consumed for the day. Unless you have an incredible memory, this will be extremely difficult to do, and unreliable at best. Instead, make an effort to write down what and how much you've eaten after each meal, and then look up the amount of calories you've consumed. Make this a habit and keep your logs for the length of the diet.

#6: Find a source of motivation. Some people are motivated by testimonials, some are motivated by pictures of their goal. Pictures of fitness models motivate me the best. I've managed to keep my current diet alive with a wallpaper from the movie 300 on my desktop, with the characters posing the six-pack that I'm aiming for. I imagine myself in the movie, pulling off all those cool combat moves with a sleek, athletic body. Testimonials don't excite me so much. However, for you, it might be the other way around. Hearing real stories from real people can go a long way to inspire someone to be persistent in achieving their goals. Find what inspires you, and saturate yourself with it.

This is another reason I recommend DietPower. It keeps a record of almost every aspect of your fitness imaginable, which is great for a perfectionist like me. This can provide a source of inspiration later on if you've been faithful to your diet, as you'll be able to see charts showing you that you are making progress in your diet.

#7: Define "Cheating". Because you'll more than likely be trying to find loopholes around that definition in moments of severe temptation. To me, "Cheating" is eating too much early in the day or eating something that I know will take me over my calorie budget for the day. That means that I allow myself to eat just about anything -- chocolate, ice cream, whatever. I do keep in mind, however, that if I only eat these kinds of foods, not only will they be a detriment for my health but they are not sufficiently filling for the amount of calories they offer. I've found that most healthy foods I have access to are quite filling for the amount of calories they offer, thus I tend to stick with healthy foods.

Discover which foods are the most tempting for you and stay away from them, too! For me an example would be tortilla chips. I love tortilla chips. Once I start eating them, I could eat them all day. This and french fries. This is why I've made a largely successful effort to stay away from large quantities of either of the two.

#8: Do not be disappointed by failure. It's nice to be able to brag about having gone an entire six months without having drank any soda or eaten any chocolate. However, you must keep in focus the point of your diet. Unless you are dieting to impress your friends (a terrible reason to do anything, I might add), you should be concerned about your health and perhaps your appearance. Having the occasional soda or donut or bar of chocolate will hurt you much less in the long run than will retaining that extra 50 lbs. of weight. Note the large spike on my calorie history graph, and note the the negligible effect (or lack thereof) on the history graph.

The biggest issue with failing your diet is the feeling of lost self-worth and disappointment, not so much the extra calories you've consumed. On most occasions someone has "failed" on their diet for the day, they are in fact still under their net metabolic rate for the day and will still end up losing some weight, albeit less. It is the psychological effect of having failed a goal that will cost you your happiness and, eventually, your diet.

#9: Don't give up, adjust. A while back, a friend of mine began a diet, and asked me for some advice. I told her that she should aim for 1700 calories per day, which I believe would've been more than enough for her to feel full at the end of the day and still lose weight. Unfortunately this did not turn out to be true, and she soon quit her diet. My advice to those who begin a diet and are struggling with keeping up with it would be to consume more filling foods with less calories (salads work for me) instead of high-calorie, sugary foods. If that's not enough, increase your budget. It could be that you have an abnormally high metabolic rate. So long as you're under your net metabolic rate for the day -- consuming less than you expend -- you will lose weight.

#10: Don't overcompensate your failure. If you go over your calorie budged for the day, one of the worst remedies for this is to compensate the loss by subtracting the difference from your next day's budget. This is especially true if you've gone over by more than 100 or so calories. Your chances of failing again are much higher, which will only push you into a depressing cycle of failed compensation attempts. If you go over, just forget about it the next day. Pretend it never happened.

As a final note, I advise everyone to do some research into the world of nutrition and fitness. Take everything you hear with a grain of salt, especially anything that sounds very optimistic. Avoid fad diets, don't be too afraid of carbs, and don't forget your unsaturated fats.




These graphs are very inspiring to me.

So what's up?

Well, for starters, I think I'm going to try and steer this blog away from me personally, except for a few occasions where I feel compelled to write about myself.

I guess this is one of those occasions, huh?

Well, so far this past September has been probably the most fun month of my life... I went camping, boating, and cliff jumping down on Table Rock Lake, went to Branson two or three times, went to Arkansas twice, swam across a lake, visited The Landing for the first time, saw the Bodies exhibit, picked up graphic design a little bit again, started my diet (again) and lost 15 pounds, discovered some cool spots to hang out right here in town, and had a bunch of other good times hanging out with friends. I've gotten into urban exploration a little bit too, and have taken up running and getting back into shape seriously. I played soccer for 10 minutes with one of my friends and was completely out of breath and unable to function! What the crap!?

Anyway, I've been managing to have all this fun and at the same time improving my grades in all my classes. I'm shooting for all A's this semester... In fact, I kind of need to get all A's.

So that's where I'm at. Also my relationship is still going strong -- me and my girlfriend are approaching 4 years of being together, which is really something! I love her more than life itself and I couldn't imagine it without her. Hopefully we'll get that knot tied pretty soon ;)

Well, that's just a quick update as to how I've been doing. This summer was great, but not as productive as the summer before, business-wise. I'm putting an end to my landscaping business, because I've decided that I need to concentrate on getting some medical experience under my belt if I ever want to make it into med school.

So, I'll probably be posting once or twice a week... we'll see what happens from here on out.

Well I'm back... for now, at least!
