Hackers On Atkins
`Sean writes "Salon.com has published a story about Hackers on Atkins. Although going on a diet is the last thing on the minds of the stereotypical geek basking in the ambient radiation of multiple monitors for 15 hours per day, many hackers have been embracing Atkins because utilizing low-carb methods to modify the metabolism is analogous to hacking and overclocking the body. Others have been combining Atkins with other systems, such as John Walker's The Hacker's Diet. I've personally lost a hundred pounds so far and will toss in the obligatory if I can do it, anyone can ism."
The future of the stereotypical fat, bearded unix admin is in serious jeopardy.

If your arguement is don't use atkins diet because atkins died, it is a little disingenuous since Atkins died because he fell on some ice, hit his head, and had a brain aneurysm.

Also, its good to eat a regular portion. If you stuffed yourself, you probably ate too much. Most restaurants will give you a dump-truck full so long as you hit their price point or $5~7 per person.
IANAD, but that's just my thoughts.
the Atkins diet makes the body digest itself because of carbohydrate depravation.
If by "digesting itself" you mean "digesting its fat stores", then yes, you're correct. I hate to be the one to break it to you, but that's what fat is for.
There's a reason our bodies have a such mode as lipolysis; it was meant to be used once in a while.
It can be harsh on your kidneys if you consume a lot of protein without drinking enough water (as in straight H2O, not mixed with caffeine, coloring and sweetener). A high protein diet puts means more nitrogen (urea) to be excreted.
But, drinking plenty of water both negates the problem and also lowers your hunger level in the first place. If you're getting the kind of side effects you're talking about, you're doing some other high protein, low everything else diet, not Atkins (at least, not properly).
Oh, and there's a difference between "getting thin" and "reducing your weight" for a lot of people -- for many, the risk of kidney damage from an Atkins-like diet is far lower than the risks of not losing that weight (high blood pressure, cardiovascular damage, heart disease, back and knee problems from the extra weight, etc, etc).

John Cash, who used to be with iD Software, once published this diet plan in his .plan back while they were developing Quake II.
Plan:
Busy, busy, busy workin' on Quake2. I wish I could tell you about it, but I can't.
For now, I'll introduce "the Cash diet" to the world. I'd never really formalized my secret diet before, but the guys and girls (w00p) in my clan dragged it out of me one night. So here it is. [drumroll]
The Cash Diet Plan
==================
What to eat:
Red meat
Lots of it. Cooked rare or medium rare.
Burgers, steaks, meatballs.. whatever.
No steak sauce, but gravy or juice is good.
Fried stuff:
Mainly potato chips and french fries.
Not those lame baked ones; real ones with
salt and oil and fat (and flavor) and maybe
bbq, vinegar, or something hot/spicy.
Dessert
Good stuff, not that low fat/low calorie crap.
Whipped cream is a definite plus. Important
note: you are not restricted to only one.
Feel free to start out with a dessert as a
pre-appetizer appetizer.
Appetizers
Loaded nachos, Buffalo wings, Onion rings.
What to drink:
Non-diet soft drinks (preferably with high
levels of caffeine)
Real beer
Snacks:
Yes, of course. Anytime you want. I find
a snack to be good right before or right
after exercising. Contrary to what you might
be thinking, fruit is actually OK as a snack...
as long as you "wash it down" with a candy bar.
Exercise:
Hey, what kind of diet doesn't include exercise?
This is the key to my diet. There is only one
exercise that is aerobic, burns lots of calories,
and you'll actually enjoy doing. As an added
bonus it can be singles, couples, or even teams.
I'm talking, of course, about good old fashioned
sex. The more the better (but take it easy when
working out alone!) BTW, here's where that
whipped cream on the desserts can come in handy.
There you have it. I think it'll catch on.. I mean,
what is there not to like?
So, I hear you thinking: sounds great, but does it really work? Well, it does for me. I'm 5'10" and
weigh 125 pounds. I eat what I want, when I want, and "work out" as often as possible (w00p!!!)
Warning: There is one possible side effect of this diet... ummm... I have two of 'em... both boys So practice safe dieting.

As one of slash's physicians, I feel I should contribute a little research on the topic. The summary of the research is that Atkin's probably works and probably lowers cholesterol. I recently read a study that followed people out for 12 months that found the diet safe.
I tend to follow the Mediterranean diet but have no better science supporting it either.
This New England Journal of Medicine article agrees with my beliefs. The important thing to remember is that weight loss requires changes to diet for life! Any diet, even Atkins, only works as long as you can follow it...
New England Journal of Medicine Article
BACKGROUND: Despite the popularity of the low-carbohydrate, high-protein, high-fat (Atkins) diet, no randomized, controlled trials have evaluated its efficacy. METHODS: We conducted a one-year, multicenter, controlled trial involving 63 obese men and women who were randomly assigned to either a low-carbohydrate, high-protein, high-fat diet or a low-calorie, high-carbohydrate, low-fat (conventional) diet. Professional contact was minimal to replicate the approach used by most dieters. RESULTS: Subjects on the low-carbohydrate diet had lost more weight than subjects on the conventional diet at 3 months (mean [+/-SD], -6.8+/-5.0 vs. -2.7+/-3.7 percent of body weight; P=0.001) and 6 months (-7.0+/-6.5 vs. -3.2+/-5.6 percent of body weight, P=0.02), but the difference at 12 months was not significant (-4.4+/-6.7 vs. -2.5+/-6.3 percent of body weight, P=0.26). After three months, no significant differences were found between the groups in total or low-density lipoprotein cholesterol concentrations. The increase in high-density lipoprotein cholesterol concentrations and the decrease in triglyceride concentrations were greater among subjects on the low-carbohydrate diet than among those on the conventional diet throughout most of the study. Both diets significantly decreased diastolic blood pressure and the insulin response to an oral glucose load. CONCLUSIONS: The low-carbohydrate diet produced a greater weight loss (absolute difference, approximately 4 percent) than did the conventional diet for the first six months, but the differences were not significant at one year. The low-carbohydrate diet was associated with a greater improvement in some risk factors for coronary heart disease. Adherence was poor and attrition was high in both groups. Longer and larger studies are required to determine the long-term safety and efficacy of low-carbohydrate, high-protein, high-fat diets.
It's not a diet where you just quit when you've lost weight. It's a change in your way of eating, and you can have still have a very proper diet on it. Once you've reached your goals, you can introduce some carbs back in (healthy ones, like fruits) to keep you at your ideal weight. You don't just quit and start eating pasta for breakfast, lunch and dinner. And, many people don't exercise because they're overweight, so losing weight often gets people interested in being more physically active.
Our "modern diet" is killing us, and since the government has been preaching "low fat" the past few decades, things have only gotten worse. People are eating more because carbs cause insulin surges which increase appetite.
Okay, this is from the perspective of one who has done Atkins, and been successful at it. Not "I heard from this guy" or "my sister's friend told me". Real experience.
I've struggled with my weight since I was in high school over 20 years ago. I've been up and down, weight wise, for a long time. Tried low fat, exercising like crazy, and just failed at it.
Finally, in February of this year, I went on Atkins for the third time (first was just a fad that I didn't do seriously, back in the 80s, second took me from about 250 lbs to 230 about three years ago,) determined to finish the plan and get to my goal weight. I also began exercising by walking on my treadmill and walking when golfing instead of using a cart.
To do Atkins properly, you spend a minimum of two weeks on "induction," which reduces your carbohydrate intake to 20 grams a day or less. This forces your body to stop using simple sugars and other carbs for fuel and start burning fat. You will most likely feel like crap for a couple of days during this phase, but it will pass.
Right about then, two wonderful things happen very quickly which are what makes the diet successful for so many people. First, you will begin to notice, within those two weeks, that your clothes are looser and, if you are weighing daily, a pretty dramatic loss of weight. This positive feedback is mostly water weight, but not entirely, and you feel like you're making progress.
Secondly, and more importantly, changing from consuming mostly carbs to mostly fats and proteins has the effect of making you feel full on much less food. In addition, your blood sugar levels stabelize and most people see "food cravings" (like eating a box of cookies!) going away. A low fat diet simply replaces fat with sugars to make the food more pallatable, and you end up with a bunch of empty calories and you're hungry a short time later.
You're told that you can eat as much as you want, so long as you keep the carbs low -- I'm not sure that I agree with that, you still need to keep an eye on calories, but the point is that after a couple of days, you could eat ten burger patties, but you'll be full after two and won't want to keep eating.
Once you've gone through induction, you can either stick with it (as I did) or start adding carbs back, a bit at a time, until you're eating a more balanced diet but still losing weight. You do have to stay away from sugars and simple carbs, though, because that will screw up your blood sugar levels.
Now, onto the myths. First, I have never seen (and I've looked) any reputable study that says that kidney damage has resulted from a healthy person (healthy in that they don't have existing kidney problems or AIDS or something) following this diet. Pointers to such a report (not something sponsored by the "American Bread Makers Association") would be appreciated, if they exist.
Secondly, people will tell you that it's unhealthy because you can't eat anything but meat. That's crap. There are loads of veggies that you can eat during induction, and you can add more, plus fruits, as you progress through the diet. I stayed on induction for seven months, and enjoyed salad every day, along with green beans, cauliflower, broccoli, etc.
Again, the proof is in the pudding (sugar free, if you please) -- in September of this year, I finished the diet, weighing 180 pounds, the first time in about 25 years that I've been the weight I'm supposed to be for my height. Now, I just check my weight periodically, and if it starts going up, I watch things for a couple of days.
Finally, the greatest help for this (or any) diet is a website I'd encourage you to use. It's free, and it tracks your caloric intake, exercise and weight. It's at Fitday
Good luck to anyone trying to lose weight. Regardless of how you go about it, it's the best thing that you can do for yourself.
Atkins or any low carb diet will only work if you are fat. Once you get down to a reasonable 12-15% bodyfay, then the low carb diet will stop being effective. So you get to go through all of the annoyance of converting the keytones for energy instead of carbs, all of the discomfort, and without any of the benefits - BONUS!
Once you get to 12-15%, you are better off going to a isocaloric diet (even percentages of fats, carbs, and protein - where most all of the fats come from the Omega3/6/9).
If you go lower total calories on that during the week and then going high carbs on the weekend (or just one day if you are highly sensitive), then you can see an anabolic rebound which is beneficial to those that are weight lifting.
It should also be noted that if you are trying to compete at all in any sort of endurance event - doing anyting low carb diet at all is about as retarded as you can get.
If you feel that you are going to do that, at the very least, try to get a lot of fruit and fruit juices so as to be able to replenish your liver glycogen levels.
But again - if you are you competetive at an endurance event, you are likely under 15% bodyfat - which means that you are wasting your time on the low carb diet.
No matter what diet you are on, as long as the calories are less than your expendatures for the day (so you can also not diet at all and just exercise more), then you will lose weight.
If you are fat - then you will see fast and great results down to about 20% bodyfat or so - then after that, you will start seeing resistance.
Depending on how long you sat at your high bodyfat levels, your leptin levels might be your worst enemy at this point - the carb loading on weekends and caloric depletions on the weekdays will help counteract that.
Once you go back to normal eating, then your leptin levels will again come back to haunt you.
So you can't just diet and then go back to eating like a pig - it is a lifestyle change.
Or you could just live life on the edge and use DNP - again, no good for endurance runners - and really no good for anyone. Especially if you are inclined towards depression at all since it prevents the conversion of tryptophan to serotonin.
Generally speaking, there is a reason the FDA banned it from diet drugs back in the day - it is dangerous - although the most effective chemical in existance for burning fat.
There are some odd things afoot now, in the Villa Straylight.
I started trying this a year and a half ago, and
wrote the following after the first few months.
All remarks are still valid:
Alimentary, My Dear Watson
While I was on vacation in early July, I happened to read the NYTimes
magazine article by Gary Taubes which opened my eyes to an extent.
The import of the article was that modern dietary conventional wisdom
has it pretty much backwards, and that eating a low-fat diet is actually
the cause of the current obesity epidemic and a lot of heart disease
and diabetes.
Getting back home and doing a flurry of research revealed that Taubes
had published a similar article in in Science about a year ago.
What he documents is that the notion that fat is bad for you is
a political, not a scientific, result, and that the actual studies
don't show it at all. Since the NIH and FDA got the bee in their
bonnet about fat, they've spent more than a billion dollars trying
to prove it, and failed.
Consider an "epidemiological" study of cars. Let's assume that the
researchers believe that engine oil is a prime cause of engine trouble.
You could quite easily take a sample that showed that there was a
strong positive correlation between cars that dripped oil and ones
that broke down. Then you could just as correctly show that you
could prevent oil dripping by not putting any oil in at all.
Bingo! The "proof" of your presumed conclusion. That's about how
rigorous the basis for the antifat doctrine is.
The reality is much more complex. In fact, the famous Boehringer
Mannheim metabolic pathways chart covers an entire wall in finely
detailed arrows and chemical formulae. But a very simplified version
goes something like this: There are three basic classes of food,
called the macronutrients; they are proteins, fats, and carbohydrates.
Proteins and fats are essential for human life; carbohydrates are not.
Carbohydrates are all converted to glucose in your bloodstream. The
more you eat, the more glucose. The body reacts to glucose in the
blood with insulin, which acts to cause cells to burn glucose for
energy and convert it to fat to be stored.
A whole raft of hormonal imbalances can result when insulin is
constantly overproduced. There seems to be some general mechanism
that tries to balance anabolic and catabolic hormones. Insulin
is anabolic. Too much of it for too long and the body will either
overproduce catabolic hormones or underproduce the other anabolic
ones.
The upshot of long-term carbohydrate consumption is a phenomenon known
as "Syndrome X", so named by Gerald Reaven, MD, professor of medicine
at Stanford. It's a cluster of symptoms that tend to occur together,
including high blood pressure, high serum triglycerides, decreased HDL,
and obesity, and marks a risk of diabetes and cardiovascular disease.
Well, go to any grocery store and look what you'll find in the
so-called "heart-healthy", low-fat foods: carbohydrates. Loads
of them. Remember, it doesn't matter whether it's sugar or starch,
honey or whole wheat, it's all glucose to your bloodstream.
So it would seem that the arrogance and ignorance of the high
priesthood of health in this country has contributed to, if not
indeed largely caused, the current (real, well-documented) epidemic
and of obesity, diabetes, and heart disease.
Oh, yes, one other thing for those of you who are into life extension
and know about the caloric restriction results -- one of the main
physiological markers for caloric restriction is low insulin.
Well, who can believe that? I did a bunch of research, and discovered
that there are more different opinions among dietary advisors than
among economists. The only thing that *everybody* agreed on was that
olive oil was good for you, and trans-fatty acids (margarine) was bad.
One of the more interesting subfields I ran across was the paleolithic
diet. The id
Theoritical conjecture? No FUD allowed here.
Give it the damn "caveman test."
"Atkins," the "ketogenic diet," and whatever else people call it is not something new. It's not something 1970's. Think millions of years, and you'll start to approach how long it has been around.
It is simply one half of the citric acid cycle, which is part of metabolism. One half is the ketogenic, the other, glucogenic.
With respect to food and hominid metabolism, there are basically 2 states:
1. FOOD (ie. times of plenty, as in: I'm eating this starchy tuber I just dug up RIGHT NOW.)
2. NO FOOD (ie. starvation, as in: Hey Gog, remember how that starchy tuber tasted that I dug up 2 days ago?)
I'm not talking about weeks of starvation, but a time frame of only about 18-36 hours. Once you have burned through your immediate glucose stores and your liver has emptied most of its glycogen stores, what happens then? Gluconeogenesis happens then. Ketogenesis happens then. Fatty acids that represent your stored energy sources are broken down into pyruvate, alpha-ketoglutarate, succinyl-CoA, fumarate, or oxaloacetate are then converted into glucose and glycogen and wisked through the appropriate cycle to give you what you need to keep chasing that small furry animal and catch it, even though your last meal was 2 days ago.
Clearly, I can't compress 4 semesters of basic and advanced biochemistry and a few years of primary research into a single slashdot post, but the basics of human metabolism are accessable to everyone from their local public and university libraries. Go buy a text book, even. Lehninger Principles of Biochemistry is an excellent place to start.
Let's approach it from another way: There is no fat loss without lipidolysis, unless you cut it out. Whether you eat NO carbohydrates and take the nose dive into the ketogenic part of your metabolism all the time, or you eat like a supermodel (small portions of carbohydrate-filled food) and experience brief periods of the ketogenic half of the citric acid cycle, it's all the same thing, only at different rates.
Worried about your kidneys and the ketobodies? Drink the amount of water a human is SUPPOSED to drink every day, and you'll be fine. Constipation is only an artifact of the change-over from starchy foods to protein and low-residue foods. After a few days things are back to normal, and you poop the way your digestive system was supposed to, in relation to what the human diet was thousands of years ago. (clue: No McDonalds and other high-carbohydrate foods)
If your varied dietary intake + caloric control + exercise works for you, then that is absolutely wonderful (no sarcasm). I applaud your efforts, and you should feel lucky that you are a fine example of an ancient metabolism that survives in an overly starchy world. For the segment of the population that isn't so lucky, the option of carbohydrate starvation (yet eating a normal intake of fatty and amino acids) is there.
Y,IAAB. (Yes, I am a biochemist.)
Gluconeogenesis takes pyruvates and oxaloacetates and converts them into glucose. You get these through catabolism of amino acids, chiefly from muscle tissue. The muscle is broken down and transported to the liver for gluconeogenic processing. Alanine, cysteine, glycine, serine, & threonine can be deaminated directly or indirectly to form pryuvate and asparagine and aspartate can be made into oxaloacetates.
Hey, that's great that you remember your high school chemistry, but the clinical data don't support your theory. Atkins focuses on foods hight in fat & protein, so there's always enough protein intake that the body does not need to break down muscle tissue. This has been gospel among body builders for 30+ years. Low-carb diets preserve muscle mass moreso than low-fat diets, and the fat loss compared to low-fat is probably more significant than current studies already indicate.
I've been fat all my life, peaking at 277 lbs eight years ago. I just finished my first year on Atkins. I'm down from 244 to 187 (that in the first sixth months actually), the same weight I was a as a high school freshman (15 years ago). Now that I've broken my carb addiction I've added healthy carbs (whole grains, vegetables, fruit) back into my diet. It's been a year now and I haven't had a donut, french fry, or any sort of sugar or junk food. My triglycerides are under 80. Is your diet that healthy?
