among the many reasons why this study is atrocious:
1) it's from 1976. seriously, no one in sciences listens to 34-year old data. hell, stuff in my field from 5 years ago is completely obsolete.
2) THIRTEEN PEOPLE? are you kidding? clinical trials use hundreds or thousands of people! to use a poker analogy, this experiment is the equivalent of saying that i'm awesome at 10/20 because I'm a 20bb/100 winner...over a sample of 100 hands.
3) it's a 2-week long study. Among other things, all of the weight loss these people had could be attributed 100% to things like water weight or the time of day the measurements were taken. Plus the cholesterol measurements don't look at important things like hdl/ldl ratio.
4) The discussion talks about limitations including the fact that severely diabetic people didn't respond at all to the treatment. this is a pretty big weakness of a study that's examining diabetic people.
If you check, I'm not citing this study. I'm using it as an example of how citing specific studies, while they use the 60% carb recommendation as an assumption, can sometimes be confusing as they target very specific segments of the population.
I challenge you to find one single exercise-based clinical trial that uses hundreds of thousands of people. Or tens of thousands. Or thousands. There are a select few that may use hundreds, but they're still on a questionnaire-type basis. Most nutritional and exercise-based trials only use from 10-50 people. This is true for a number of medical studies of this nature as well. While it would be nice to have hundreds of thousands of people follow the exact same testing protocol, it's pretty close to impossible to make happen.
There are limitations to every study. In fact, one of the understood requirements of a medical or physiological study is to make the limitations of the study explicitly clear to provide basis for additional research. A 2 week period was likely required to accomplish the goals of this particular study - but again, as I said before, this isn't a performance study. I used this citation as a means to show that citing a specific study can be tough as they're extremely specific to a certain segment of the population and to a solitary purpose or desired response.
1) EIGHT PEOPLE? This is even worse than the first study
2) Their subjects are completely different, so it's beyond impossible to say what caused anything. If you're gonna do this study, make it long term and use people of the same sex with similar body types. Do you think you metabolize food the same way a 90lb woman does?
3) They don't measure anything relevant to our discussion at all. Why do I care that adding more carbs to your diet means that you are more capable of processing carbs? That's the body's natural efficiency.
As I said above and below this link, this is another example of how citing a specific study can be confusing IF you're looking for it to be pertinent to our discussion. The purpose of its citation was to show you that it's being used as an assumption for a generally accepted balanced diet.
I then go on to say that the solution to filtering through each and every case study would be relying on a review of literature, which is a common inclusion into various medical journals as a means of reaching a generally-accepted assumption with which to base future teachings and directions for research.
1) I'm not going to take anything seriously from a site that has an ad for high fructose corn syrup on the side. I can't believe you're using this as evidence.
It's very unlikely that this site has anything to do with their ads. They're likely set up with an ad network that places ads that their system believes are relevant to those visiting it. One of the sites I was involved with years ago had an ad network included on a sidebar that sometimes had ads for HGH. Do I endorse it? Not outside of certain types of medical rehabilitation, no.
2) Their first "fast fact": Americans eat 60% more cereal than they did in 1970. WE'RE ALSO WAY FATTER THAN WE WERE IN 1970. How on earth does this help your cause?
3) fast fact: The average American eats 142 pounds of sugar and corn syrup a year, along with 24 pounds of low-calorie sweeteners. again, how is this helping your case?
4) Ok this is a direct quote: Sugar is not just a source of empty calories. W.T.F. this article is seriously an ad from a sugar company or something. I'm done.
Again, the major purpose of this citation was to show you that the nutrient proportions I advise are included in the assumptions of most other academic minds in the field.
5) OK one more, because I spit out my drink when I read it: The evidence points to obesity, not sugar, as a major cause of diabetes. WHAT?!?!?! HOW DO PEOPLE GET FAT? Travis, you lose 100% of your credibility by citing this.
People don't necessarily get fat from eating too much sugar. If they're burning more calories than they take in, they won't become obese regardless of their nutrient intake. That being said, they'll still have some significant health problems if their nutrient balance is skewed, and diabetes may in fact be one of these problems. I can definitely see the validity of labeling obesity as possessing a higher degree of danger when it comes to chronic health conditions, so I'm not sure what your disagreement is here.
Also, if you believe I've lost credibility in your eyes - fair enough. That said, I'm not really searching for credibility in the eyes of those who are resistant to making positive changes. My credentials, resume, and experience speak for themselves. I'm also not sure, based on the feeling I get from your arguments, that I had any chance at gaining any sort of credibility in your eyes to begin with.
I'm not bothering with this one really since it says a lot of random googleable crap about carbohydrates and isn't very useful. I'll point out, however, that it does say low-carb diets like atkins are effective in terms of weight loss. To DC: how many people that you know have gone on some super low-fat diet and not lost ANY weight?
The Atkins diet may in fact make you lose some short-term weight. That being said, the goal here isn't losing short-term weight to satisfy cosmetic goals (which are the goals of many following the Atkins diet), but to eat for optimal athletic performance.
this article is basically parroting USDA BS, but I'll point out that it says corn flakes (healthy, right?) have a glycemic index higher than sugar. Hooray grains!
If you don't want to believe what health organizations say, I can't really say anything to convince you as my arguments are based on information provided by health organizations and institutions.
That said, your assumption is that corn flakes are healthy. Why is this the case? Because it is a fact that their GI value is extremely high, and such foods can lead to insulin spikes which are detrimental to brain function and performance.
If this were an academic discussion or a comparison of research, I'd participate. However it seems as though I'm defending standard recommendations made in the health profession against your opinions. I can't, therefore, warrant any more time participating in this discussion. Nothing personal, but if you're not convinced by major organizational stances backed by research, I'm afraid I've got no way of convincing you at all.
