Obviously there is a lot of interest in cardio training and how to do it right. Sadly, most people are still doing 2 things terribly wrong and it’s killing their results…… As best as I can figure, there are two major reasons why people are still mucking up their cardio programs for fat loss.<br /><br />REASON #1: NOT ENOUGH FOCUS ON TOTAL CALORIES BURNED<br /><br />Most people aren’t burning enough darn calories.<br /><br />Why? Well, I guess they are too busy worrying about the “proper” type of exercise (which machine or activity), the mode (steady state or intervals), the “optimal” ratio of intervals, or the “best” duration.<br /><br />Some people coast along on the treadmill at 2.3 miles per hour or some similar sloth-like pace and they think that just by hitting a TIME goal, such as 45 or 60 minutes, that with “X” duration completed, they are assured to get the results they want.<br /><br />On the other extreme, we have folks who have found or created some mega-intense, super-duper short training protocol like the “4-minute wonder workout from Japan.” Just because the workout is high in intensity and it is performed in intervals, they too think they are assured to get the results they want.<br /><br />What’s missing in both cases is the realization that total fat loss over time is a function of total calories burned over time (assuming you don’t blow your diet, of course).<br /><br />AND…<br /><br /><a href="http://www.weightlosseasy.tips/2-cardio-mistakes-youre-still-making.html" rel="nofollow">2 Cardio Mistakes You're Still Making</a><br />Anonymoushttps://www.blogger.com/profile/07576039331066946246noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-55012113994817436102010-11-08T09:59:50.467-08:002010-11-08T09:59:50.467-08:00The wheat piece is probably the big clue - but per...The wheat piece is probably the big clue - but perhaps not the way you think. The big shift in western diets occurred with factory farming from the 1950's. This led to a massive shift in Omega3/6/9 ratios in the diet. A diet rich in O3's reduces insulin sensitivity and leads to better functioning mitochondria. Factory farming shifted to grain based foodstocks for most animals - which massively increased the O6's at the expense of the O3's. One classic example is chicken. < 1950's a chicken breast contained over 120mg of O3's, nowadays < 20mg.

I wonder how common those ailments were?<BR/><BR/>I've read a bit about S American archaeology, and I've picked up a few interesting facts. Corn was not a widespread dietary staple until about 800 AD. When it became a staple, skeletons showed the characteristic signs of grain adoption: shortened stature, osteopenia, osteoporosis, narrower pelvic inlet, tooth decay, skeletal signs of anemia. Probably due to the increase in dietary anti-nutrients and the replacement of nutrient-dense foods.<BR/><BR/>I do believe it's possible to be overweight without eating wheat, by the way. It just seems like rampant, society-level obesity only occurs in wheat-based cultures.<BR/><BR/>I agree that boundary cases are fascinating, that's exactly why I've latched on to the Kitava study.Stephan Guyenethttps://www.blogger.com/profile/09218114625524777250noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-82147739174284034632008-08-21T09:54:00.000-07:002008-08-21T09:54:00.000-07:00Chris,That is an excellent article, thanks for sen...Chris,<BR/><BR/>That is an excellent article, thanks for sending it my way.

Thinking about boundary cases like the Inuit and Kitavans is interesting and informative.<BR/><BR/>I started poking around to try and find other cases, e.g. is there a population that eats a lot of wheat and little or no sugar, or a population that suffers from "diseases of civilization" without wheat. One interesting instance is the Aztecs, which you can read about here:<BR/><BR/><A HREF="http://www.geocities.com/wasicugohome/aznutrition.html" REL="nofollow">http://www.geocities.com/wasicugohome/aznutrition.html</A><BR/><BR/>The relevant stuff is down in the middle of the article. Here's some interesting excerpts:<BR/><BR/>"The Badianus Manuscript index provides commentary on approximately 100 medical conditions. Of these, 10% are nutrition or foodintake related and include reference to conditions of angina, constipation, dental problems (tartar removal), dysentery, dyspepsia-indigestion, fatigue, gout, heart (overheated), hemorrhoids and lactation difficulties. No references appear in this manuscript that could be equated with beriberi, pellagra, rickets or scurvy, or to medical-nutrition related conditions such as cancer, diabetes or stroke...<BR/><BR/>Other texts document nutritional problems among the Aztecs, including heart disease, kwashiorkor(5) and obesity. Ortez de Montellano (1990) wrote that traditional Aztec diet apparently was low in saturated dietary fats, given only modest intake of meat and the lack of dairy products before the Spanish conquest. He suggested that such a pattern, coupled with a presumed high level of physical activity among Aztec workers, would minimize cardiovascular disease. Yet his review of surviving Aztec documents identified heart ailments such as angina and "overheated heart."...<BR/><BR/>The Aztecs had a sophisticated vocabulary for obesity and locations of specific fat deposits: cotztzotzol--soft, drooping fat and skin deposited along the calf; eltzotzolli--flabby, fatty tissue and skin deposited across the chest; ititzotzolli--soft, bland fat and skin in the hypogastrium region; puchquiyot| very flabby fat widely distributed over the body; and quechtzotzol--a flabby, double chin (Lopez Austin, 1988, p. 259)."<BR/><BR/>I haven't had a chance to think about this in detail, and would like to uncover other similar cases as well. But the similarities and differences (e.g. heart disease and obesity but no cancer or diabetes) are thought-provoking. Corn, of course, comes with its own complement of anti-nutrients, e.g. lectins. Comparison with wheat for similarities should be educational.Davehttps://www.blogger.com/profile/18290594860469294453noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-74939253495624693512008-08-20T15:39:00.000-07:002008-08-20T15:39:00.000-07:00@StephanI'd love for you to expound on your skepti...@Stephan<BR/><BR/><BR/>I'd love for you to expound on your skepticism on GI/GL. One thing that popped out at me from Wikipedia:<BR/><BR/><I><B># GI takes into account only the resulting glucose in blood chemistry, with no consideration of the effect of other sugars, particularly fructose</B>. An example is Coca-Cola. While already having a medium GI rating, Coca-Cola actually contains even more sugar than is otherwise being accounted for by the GI, as it contains HFCS 55, meaning that for each serving, the 55% fructose is not being accounted for. High levels of fructose cause the same blood sugar spike as a similar amount of glucose[citation needed]. While fructose does not produce the large insulin response of glucose [2], it can cause its own set of health problems, due to an increase in plasma lipids.

I've also been ...Hi Dave,<BR/><BR/>Thanks for your thoughts. I've also been following Peter's recent posts with great interest. It definitely makes a case for saturated fat, or more precisely, avoiding polyunsaturated fat if you eat carbs. <BR/><BR/>One thing that bugs me about the argument that one must eat low fat on a high-carb diet to avoid insulin resistance is that there are empirical counter-examples. The Kuna of Panama don't seem to get the diseases of civilization, including overweight, even though their diet composition is similar to an American's (their fat is more saturated however). They get most of their carbs from plantains and cassava, but some from fruit, corn and sugar as well. Not much grain intake, virtually no wheat. I just don't think the answer is to be found in macronutrients. Why would our bodies have evolved to tolerate certain ratios of macronutrients and not others? The best design would accomodate whatever combination of food sources came along, and they did come along in every combination.<BR/><BR/>I can understand the argument for limiting polyunsaturated fats in a high-carb diet. I'm not aware of any non-industrial populations that are healthy on a high-carb, high-polyunsaturate diet. That's not to say there are none, but I haven't come across them. <BR/><BR/>I don't know what the Kitavans' lipoprotein numbers are, but their total cholesterol is about 30% lower than a Swede's on average. HDL is a bit lower, LDL is lower and trigs are a bit higher than Swedes. I published some of the numbers a few posts ago. <BR/><BR/>Kitavans probably do get a lot of vitamin C from all the fruit they eat. They also have a relatively high DHA intake, from the 4g of fish fat they eat per day.<BR/><BR/>I haven't heard about the effects of sweet potatoes on insulin sensitivity, but I don't think you have to invoke that to explain Kitavans' carb tolerance. For example, in the Papua NG mainland they eat plenty of sago palm, which is pure starch. The Kuna get their starch from plantains. They are both lean and healthy. It seems like the outlier is wheat rather than sweet potatoes. <BR/><BR/>About the stress factor, I believe Lindeberg made a brief attempt to address that. He says that on Kitava "Suppressed aggressiveness seems common. Intense fear of sorcery clasps everyone." I think it's very hard to determine a culture's stress level from a few months among them, so it's still possible that they have less stress. But at the very least, the answer is not straightforward.Stephan Guyenethttps://www.blogger.com/profile/09218114625524777250noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-4784427089376262342008-08-19T19:30:00.000-07:002008-08-19T19:30:00.000-07:00Hi Stephan. Here's some wild-assed speculation...I...Hi Stephan. Here's some wild-assed speculation...<BR/><BR/>I agree that the "carbohydrates drive insulin drives fat storage" is an oversimplification. The details of the process are interesting. LPL activity is considerably delayed from the initial insulin signal. LPL activity in adipose tissue peaks around 4 hours or so from the initial insulin spike. This corresponds nicely with the the peak of plasma chylomicron density from dietary fat; and though I don't know off the top of my head, I'll bet VLDL from the liver carrying triglycerides manufactured from dietary carbohydrate also enter in around the same time window. By this time, blood glucose has returned to nearly baseline. Peter has some excellent speculation on the Hyperlipid blog as to why evolution designed us this way, essentially to separate lipoproteins from elevated blood glucose, since the glucose damages the lipoproteins. It is these damaged lipoproteins which are implicated in the development of CVD due to the inflammatory reaction they cause.<BR/><BR/>So that in itself is a nice story, and is consistent with the absence of CVD in Kitavans. Their diet is not only relatively low fat, but a lot of the fat (presumably from coconuts) is MCT, hence does not require chylomicron transport. All in all, one would presume that the Kitavans would have lower numbers of lipoprotein molecules than would Westerners (who eat large relatively larger amounts of fat with their carbs). Less lipoprotein, less potential for damage. Wild speculation: Kitavan sources of carbohydrates are also high in anti-oxidant (and anti-glycation?) micronutrients, potentially extra protection. All of these aspects may lend further protection against the effects of smoking (not the least of which, I imagine, is increased oxidative damage to lipoproteins).<BR/><BR/>Plasma non-esterifed fatty acids (NEFA) cause insulin resistance, particularly in muscle (the main "sink" for dietary glucose). These would also be peaking around the time that chylomicrons/VLDL/LPL peak. If you eat fat with your carbs, you may be more insulin resistant for the next meal. Kitavans eat relatively low-fat, and a lot of the fat they do eat (MCTs) gets a ride straight to the liver, and much of that is presumably used for energy (the liver likes fat). So less NEFA, less insulin resistance, better glucose tolerance.<BR/><BR/>Another aspect: Vitamin C and glucose compete for binding sites, being chemically very similar. Vitamin C, amongst other things, strengthens connective tissue (like the inside of arteries). High intake of Vitamin C would be protective against some of the damages from dietary carbohydrate. I'll bet the Kitavans get a LOT of Vitamin C.<BR/><BR/>Omega-6/Omega-3 ratio is too coarse of a measure. Plant-based omega-3 (ALA) is inefficiently converted to its biologically useful form (in humans) DHA. The rest is just fodder for increasing oxidative stress, including oxidative damage to lipoproteins. Do the Kitavans get a fair amount of DHA from seafood (the requirement is actually quite small, I believe)? <BR/><BR/>We discussed a bit on my blog the possibility that grains could contain anti-nutrients that interfere with insulin signaling. I also mentioned in my last comment that some wild tubers (yams and sweet potatoes?) may have the opposite effect, actually helping with insulin control. I don't know the mechanism, but increasing insulin sensitivity and correspondingly glucose clearance sounds reasonable.<BR/><BR/>Let's not overlook the effects of psychosocial stress. Most primitive societies live rather low-stress lives (sort of ironic that we call them "primitive", isn't it). We all know chronic stress is bad. Increasing insulin tends to temporarily depress stress hormones; insulin also lights up the same brain reward centers which are studied in the context of addictive disorders. Maybe it's no surprise that "comfort foods" are almost invariably high-carb. A low-stress lifestyle may mitigate overconsumption of carbohydrates, allowing normal energy regulation mechanisms to work properly. Additionally, normal levels of stress hormones probably make for better glucose tolerance, lower insulin levels, etc.Davehttps://www.blogger.com/profile/18290594860469294453noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-58212385623267339792008-08-19T09:21:00.000-07:002008-08-19T09:21:00.000-07:00My Year Without,It really is ubiquitous, isn't it?...My Year Without,<BR/><BR/>It really is ubiquitous, isn't it? I think that's why it's so valuable to have data from cultures that don't eat it.<BR/><BR/>Kayaman,<BR/><BR/>I'm not completely abandoning the GI/GL just yet. I'm still open-minded to the possibility that it could play a role. I just don't think the totality of the data are convincing at this point. <BR/><BR/>Sugar in the large amounts we consume in industrial nations has a large load of quickly digesting glucose and fructose. That could be the key. Or it could be something neurological, for example the sweet stimulus is so large it tricks our appetite centers. I'm not really sure what the mechanism is, I've simply noticed that where sugar goes, disease follows. <BR/><BR/>Although to be honest, it usually shows up at the same time as wheat and other processed foods. I don't think sugar alone is sufficient to cause the diseases of civilization. The Kuna eat plenty of refined sugar and they're healthy. But they don't eat wheat and not much grains in general.<BR/><BR/>If I had to guess, I'd say it's a contributing factor but not sufficient to cause disease by itself.Stephan Guyenethttps://www.blogger.com/profile/09218114625524777250noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-73865502927095367972008-08-19T09:02:00.000-07:002008-08-19T09:02:00.000-07:00If the GI/GL isn't that important, than what's so ...If the GI/GL isn't that important, than what's so special about sugar that causes hyperinsulinemia?

I agree with your comment, "In my opinion, the trail of metabolic destruction that has followed Westerners throughout the world is probably due in large part to wheat and refined sugar." I believe that to be true because those ingredients are in just about everything--all those packaged products. I have gone without refined sugar all year, so far, and it has led to going without refined flour, as well. It is unbelievable to see all the refined ingredients in packaged products. There has to be a link, like you said, between failing health and refined products, especially the AMOUNT of refined products in packaged foods.

That is one of the biggest lies perpetuated on overweight and/or diabetic patients, which leads to further weight gain and/or diabetic complications, because they can't keep their BG/insulin in a normal range on the prescribed high carb diets. <BR/><BR/>Those GI/GL tests were done on people with healthy BG/insulin-sensitive systems to begin with, so are not valid for those with impaired or over- burdened BG regulatory systems. <BR/><BR/>I have tested my BG with my glucose meter (calibrated against my labs test results) after eating many, many foods, and fiber or not, starch converts to glucose quite fast with or without fiber. I find little difference in my BG readings between whole grain and white flour, it's always much too high and starts a roller coaster effect. Starchy veggies are much the same. <BR/><BR/>The highest BG reading I have ever had from a food came from a measured serving of Cheerios cereal, supposedly a "whole grain" and emblazened with the AHA seal of approval. I now view whole grain cereals as predigested starch, a veritable bowl of sugar. <BR/><BR/>Whole grain is a misnomer anyway. What is called whole grain is more often actually "whole meal" or "whole grain flour". If the grain is crushed, milled, flattened, rolled, cut, etc., it isn't whole anymore.Annahttps://www.blogger.com/profile/17033443643442246531noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-36739659615188747462008-08-18T10:17:00.000-07:002008-08-18T10:17:00.000-07:00Hi Stan,If I understand correctly, you're saying t...Hi Stan,<BR/><BR/>If I understand correctly, you're saying that snacking is the problem?

Are people overweight because they snack, or do they snack because their metabolism is screwy?<BR/><BR/>I think it's worth pointing out that the Kitavans' root vegetables are not particularly low GI/GL. They eat a lot of them, and don't eat much fat to slow down digestion. Makes me think we're able to handle it if everything is running smoothly.Stephan Guyenethttps://www.blogger.com/profile/09218114625524777250noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-56847204367721045792008-08-18T10:10:00.000-07:002008-08-18T10:10:00.000-07:00Hi Jeff,That's pretty much exactly what I'm thinki...Hi Jeff,<BR/><BR/>That's pretty much exactly what I'm thinking. Low-carb sidesteps the problem of a damaged metabolism, while reducing the consumption of the biggest offenders.<BR/><BR/>Kitavans eat sweet potatoes, cassava, taro and yams. I don't see any reason to think that their root crops are qualitatively different from ours (sweet potato, potato). Yams, sweet potatoes, taro and cassava are all very starchy. Taro actually has more starch per weight than a potato. The glycemic index/load of these are not particularly low.<BR/><BR/>By the way, I checked out your blog, looks interesting! Sounds like you've made some good progress. Glad to have you on the blog.Stephan Guyenethttps://www.blogger.com/profile/09218114625524777250noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-14437953240038071242008-08-18T10:02:00.000-07:002008-08-18T10:02:00.000-07:00Hi Julie,That's pretty much what I'm saying!

Make sure to send me a photo of his expression.Stephan Guyenethttps://www.blogger.com/profile/09218114625524777250noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-53033259986054770662008-08-18T08:26:00.000-07:002008-08-18T08:26:00.000-07:00I have a slightly diffrent speculation on this sub...I have a slightly diffrent speculation on this subject, see my Aug-15 post:<BR/><BR/>http://stan-heretic.blogspot.com/Stan Bleszynskihttps://www.blogger.com/profile/03922719716458272303noreply@blogger.comtag:blogger.com,1999:blog-1629175743855013102.post-32889845324229327212008-08-18T05:15:00.000-07:002008-08-18T05:15:00.000-07:00Stephan,Great post, as usual.Low-carb does look li...Stephan,<BR/><BR/>Great post, as usual.<BR/><BR/>Low-carb does look like a simplification. The details about which carbs appears more important. Low-carb, since it avoids the problem stuff, will get you around the problem. Eating the "right" carbs would also work.<BR/><BR/>Can you provide more detail about the types of tubers they eat? Is it like our potato, or is the potato too starchy and not fibrous enough?<BR/><BR/>Thanks,<BR/><BR/>jeffJeffhttps://www.blogger.com/profile/13704929106479058019noreply@blogger.com
