I lost the weight in two weeks.

I am now on a maintenance diet. It is not nearly as restrictive.

I would recommend the Atkins diet. I have found it to not only work in weight loss but to also increase energy.

And I went to your link, and followed the links included in the doctors pages, and noticed that they were long on rhetoric, and VERY short on numbers. Do you have any other resources? Not only were several of the links down or missing, but the ones that were up had not research in them. They were as much anecdotal as anything else put forth, including my anecdotal evidence(which I admit is anecdotal in the first place....my only caveat being that I'm a tough sell, I am one of the most cynical bastards walking around it's said). I would probably look further into it than you have.

Did some quick searches and reads. I call your six links to dubious sources and give you twent or so odd to start with..(I was quite surprised one of my fellow II members would put forth a site that seems oddly akin to a YEC page, I should think we, being more critical than the average person would have searched both sides and looked for multiple sources)

BTW, my wife is up to 41 pounds lost(she's slacking off the drop and is at a more ideal weight, she is on a low maitenance plan.

I quote one of the sources you posted--

Quote:
In the study in question, Dr. Eric Westman of the Duke University Medical Center looked at both. He followed two groups of 60 dieters each, one on a high carbohydrate diet and one on the high-fat, low-carbohydrate Atkins diet. He reported that the Atkins group lost twice as much weight during the six-month study period as did the high-carb group. But this is both unsurprising and meaningless.
Note that I don't think "But this is both -snip-" was Mr. Westmans take on the situation, but rather the guy who posted the page...His language is a LOT less logical.

First off, what's wrong with quackwatch? While I agree that their references are a bit light, and some are out of date, I think it's funny to see the vigour with which they attack the fringes of the medical establishment. Cetainly worth a laugh or two.
Personally, I haven't put up much research to substantiate my position largely because it is a debate I see little interest in pursuing. While I'm content to discuss it, "proving" my point will invlove a lot of work I'm not prepeared to invest at the moment. It's been my experience that people will ignore whatever evidence is presented to them to "give it a go" themselves to see if it works. Besides, most people are looking for the quick fix and put little to no thought into the long term health consequences of their present dietary behaviours.
I really find it interesting that people are willing to subject themselves to diets that haven't been proven to be beneficial to the human organism. My understanding of the scientific process is that strong evidence is supplied before moving on to clinical trials. Fad diets bypass all of this to hit the market first, THEN they start to look for scientific links to substantiate their claims.
You may say that you'll feel "vindicated" once the evidence supports the action you are presently taking. How are you going to feel if it doesn't eventuate? Are you going to continue the behaviour, denying the evidence, believing that one day, you'll be proven right? If that's the chance you're willing to take, good for you. Sure as hell isn't anything I'm willing to bet on.
As for the longitudinal studies presently being performed, I have no idea as to the time interval they are using. To get a really good idea about morbidity related to low-CHO diets, you'll need quite a large window. I doubt that the present studies are aiming for a 10 or 20 year duration. Those will not eventuate until after the present round of studies are completed, and likely only if those present favourable results.
Enough rambling. I need sleep.

Who are you talking to? The people here who don't agree with you but have actually done research on the subject? I thought everyone here was engaging in a science debate.

This might come as quite a shock to you Godot, but most people don't seek alternative medicine just to prove you wrong. It has nothing to do with you - it has everything to do with them wanting to get better. Sure wait for the studies - they take 10 or 15 years, and often their results are inconclusive. People will listen to the medical establishment up to a point - but when the medical establishment isn't working for them (or if they happen to get an arrogant doctor), then they will look for other remedies.

:banghead: I did a pubmed search last night on the Atkins diet - and it wasn't overwhelmingly negative. There were positives and negatives about it - and as many people here have pointed out - it appears to work for some people. Maybe not for the reasons Atkins said it did. So fucking what? I'm a scientist just like the next person, but I'm also a future doctor. If something is working for my patient, even if it seems to contradict what the Holy Science or Nature says, I'm not going to tell them to change it
just so I can be right.

I got the impression from your posts that you are some type of medical professional. If this is true, I surely hope that you treat your patients with more respect than you have treated members here who disagree with you. If you don't - your patients will not only seek out 'quack therapies,' but also they won't tell you about them for fear of looking stupid in your eyes.

But they are human, and prone to the same fallabilities as the rest of us. In other words, quackwatch has a purpose, like other such sites. I don't take what they say without a bag of salt, but I do read them.

I am a hard sell, after all.
You may say that you'll feel "vindicated" once the evidence supports the action you are presently taking. Vindication is not on my mind, I just wanted to offer the flip side. How are you going to feel if it doesn't eventuate? I won't feel anything, I have always been open minded, especially if the research is good and the numbers jive Are you going to continue the behaviour, denying the evidence, believing that one day, you'll be proven right?Nope, waiting for studies, but anecdotal evidence, and several short term studies are pretty positive. I don't know the future however. I actually wanted to let you have the benefit of the doubt, so I hinted that it would be *best* to wait on the long term studies before disapproving, or approving. I only have first hand knowldege, and anecdotal evidence of acquaintances. As I said, I couldn't do the diet, but those who do and remain on it do well. If that's the chance you're willing to take, good for you. Sure as hell isn't anything I'm willing to bet on.
As for the longitudinal studies presently being performed, I have no idea as to the time interval they are using.I think they are doing 3 year increments, and 5 year increment studies, looking at 10 and 15 year spans overall, and I'm sure they'll do a 20+ study as the time has passed. I'm of course not positive on the numbers, it's been about 7 months since I looked into the diet for my wife To get a really good idea about morbidity related to low-CHO diets, you'll need quite a large window. I doubt that the present studies are aiming for a 10 or 20 year duration.It does after all take TIME to get to 20 year studies Those will not eventuate until after the present round of studies are completed, and likely only if those present favourable results.

In other words - it isn't an immediate compensation of a low-sugar diet. It's one of the reasons diabetes can be a problem - your brain never uses the damn ketones cuz sugar is always too high to turn on the ketone enzymes. Starvation in the midst of plenty.

Is this true?
It is. I phrased my sentence wrong. Ketosis will only be entered when sugar intake is very low (ence the very low carb biggining fase in the Atkins diet), but after that a sligthy higher carb intake won't necessarily push you out of ketosis back to your staring point. We bodybuilders regularly use keto diets intervaled with short higher carb periods. Anyway, for ketosis to be entered there has to be, at least to some degree, and absence or very low quantity of oxaloacetic acid, a by product of carbohydrate metabolism, that prevents ketone bodies formation. So I guess you are right and my statement, writen as it was, was wrong.

I've already stated the following twice now, But I'm going to say it one more time:

I've been on a carbohydrate-controlled diet for SEVEN YEARS now and have had nothing but positive results. My experience overrules ALL the rhetoric that any and all other persons on earth can spew from now until the end of time.

Is there really anyone presently reading these words that is TOO FUCKING DENSE to understand this? Is there REALLY someone who actually reasons " Well, this guy's totally positve experience over the last seven years with this diet should not count for him, because it says YADDA YADDA YADDA in this here pronouncement by this here authority who SAYS that the scientific evidence shows that BLAH BLAH BLAH. This guy should just follow the advice of the recognised scientific experts in this field, because they're, well, the EXPERTS, not him. His experience shouldn't count for him."

I repeat, is there really someone posting to this board who sees things this way? If so, then all I can reply is: **** ***

I think you mean, If not, right?

And of course, the asterisks stand for "dine out," right?

The trouble with doing medicine that way is that there could be other variables. I'm sure your diet is working for you - and apparently not doing any harm. However, is it the diet? The diet and other stuff? The diet and your specific genetic make-up? This is why controlled studies are so important.

When you say carb controlled -are you specifically referring to the atkins diet? Seems to me that the downsides of the atkins diet aren't the low carbs necessarly, but the high fat.

And I'm still glad that several of you in this discussion are not my primary care provider (except you Dr Rick!) Man o man you'd think we were talking about abortion at Christian forums or something! It's just fat and carbs people, nothing to start a war over!
