Transforming biochemistry knowledge into weight loss:
This page was begun as an experiment. An experiment I was conducting on myself. An experiment to test which conditions would allow me to loose weight. Now that I have been at it for a while I realize this page serves as more. It serves as a means for me to research. It is a way for me to pick health topics of interest, research them from a biochemistry stand point, and then share them with the world. Sharing them with you gives me an official feeling and keeps me motivated. However, as described below, I am still experimenting on myself.
How did this happen? I don't know exactly although I am almost sure it boils down to diet and exercise. I hope to find the answers as I explore my journey through weight loss on this blog. I was not always fat. Therefore, I know that I can be unfat again.
I am a biochemist. I should have known better. Of all people, I should have known how to avoid this predicament I am in now. I now wish to harness my scientific knowledge to experiment on myself as well as explore the chemical basis for weight loss methods.
Methods:
I will try new diets. I will experiment on myself. The diets will be chosen from among the most popular in our society. I will chronicle the results and my general experience in my blog here. I will also explore the biochemical basis for these diets as well as evaluate their effectiveness and truthfulness. I will also exercise as regularly as possible, 3-5 times per week, to avoid biasing the results. I will try to keep everything constant in my life except the diet. My method is not perfect. I don't necessarily want to lose raw pounds, but rather gain an understanding of what methods work best for me to permanently regain my health.
Hypothesis:
1. No diet will be clearly better than the others. Conversely, each diet will offer some truth, some piece of knowledge or methodology that I can take away with me to help myself. I think that in the end, I will be able to formulate my own diet based on a synthesis of all the things I have learned from all of these diets.
2. I have been on diets before, lost weight, and then regained it. I wasn't born fat. Given that, I think that my main problem will be shown to be psychological. I think that I may have compulsive eating problems- compulsive eating problems associated with very unhealthy foods.
3. I will lose quite a bit of weight. My blog will help keep my motivation levels high.
4. There will be a lack of clear scientific basis to many of the diets.

March 7, 2010 (ethanol metabolism)
I weighed in today at 249.2!!! This marks a breakthrough for me, at least mentally. Dipping below 250 is important to me as a marker of success. I want to reach at least 220, and perhaps even below 220. So I am over half way there.
I had eggs, cheese, and turkey bacon for breakfast. A couple cheese sticks for snacks. A tomato with balsimic vinegar and chinese style chicken breast (cooked in olive oil). I had Chinese style chicken and broccoli for dinner. Only water today to drink.
I went back to the foot doctor last week and got more injections in my feet. They aren't better yet. But, I have been making an effort to exercise in creative ways anyways. I started yoga. It is amazing how inflexible and weak I was. I also enjoyed it very much. I hope to keep up with it. I also have been swimming. I have felt better.
I wanted to explore one aspect of biochemistry I am always curious about- ethanol. And when I say ethanol I mean getting drunk. How does this effect being fat. Studies have indicated that drinkers generally consume more calories. It is also obvious that if you drink a lot of beer you will gain wieght from the excess calories and bad carbs. But, what I want to know, is what effect does ethanol itself have on weight? For example, if one was to drink pure everclear, how is it metabolized? There seem to be a few steps:
1. Ethanol is converted to acetaldehyde via oxidation by alcohol dehydrogenase. As far as I can tell this occurs in the liver.
2. Acetaldehyde is converted to acetic acid. This is done by adlehyde dehydrogenase 2 family (ALDH2). Interestingly, a large portion of ethanol metabolism stops here, when getting drunk, and a lot of ethanol is then excreted out as acetic acid in the urine (full metabolism ends in CO2 and water). I think this is because the TCA cycle gets overwhlemed by the amount of acetyl-CoA around.
3. Acetic acid is then converted into aceetyl-CoA by ACSS2. Interestingly, this step requires ATP.
4. Finally this acetyl-CoA is fed into the TCA cycle. This yields water and carbon dioxide and some ATP.
It seems to me this is a fairly neutral process as far as weigh loss is concerned, especially if most of it is urinated out at the acetic acid step. But I know that ethanol metabolism messes with blood sugar (part of the reason you get a hang over), in the direction of low blood sugar. Why is this?
Apparently alcohol inhibits the liver from making glucose and alcohol increases and prolongs the action if insulin, I am not sure of the mechanisms of these.
