Guest guest Posted March 3, 2009 Report Share Posted March 3, 2009 Why do you feel obligated to eat ice cream with sugar and commercial applesauce? michael, sorry i meant i sometimes feel obligated to eat lots of greens and veggies and fruit and " healthy whole grains " --the whole grains i don't do. i have only had cravings for the ice cream and applesauce. and i am sure it's b/c i am not eating enough protein and fat at regular intervals. Why does your starch have to be in the form of pasta (and I imagine store bought improperly prepared pasta at that)? well, for whatever reason things like homemade macaroni and cheese or fettuccine alfredo are what i want more than potatoes. so i use rice pasta--the Tinkyada brand that is supposed to be better than the rest. i don't really know what " properly prepared pasta " is or if it even exists. i am a true perfectionist and it's hard for me not to be able to eat what i always imagined i would when i was pregnant for the second time. (the first was a disaster) and i am trying as hard as i can to eat the very best foods, but it's been really hard, much harder than i expected. amanda Quote Link to comment Share on other sites More sharing options...

Guest guest Posted March 3, 2009 Report Share Posted March 3, 2009 The study was showing that the intake of a type of sugar from fruits, vegetables, and honey had a negative impact on the immune system at 100g intake (3.5 oz) at any given meal.

Guest guest Posted March 3, 2009 Report Share Posted March 3, 2009 There are a ton of listed studies in the glossary. I'm not sure which two show are for the charts displaying how various carb weaken the immune system. I don't think properly preparing the food helps. The reason for this is it's more of an issue the type of sugar it is and how it converts rather then how many enzymes/probiotics it has in it and being predigested.

Guest guest Posted March 4, 2009 Report Share Posted March 4, 2009 Yeah, I'd go the optimal diet www.homodiet.netfirms.com And then I would eat all my meat and my fat raw. I would do prep with my veggies and starches. Barry Groves in his book Trick and Treat doesn't talk at all about fermenting, culturing, and he doesn't specify if the carbs have a bad effect on the immune system when eaten with fat and protein. I thought it was strange starch didn't have much of a negative impact on the immune system. I thought that would be the worse. I'm so confused.

Eating a low carb diet, like any diet requires careful planning. A common problem is that if the ratio of protein to fat is wrong, you can get very ill. Dr. Steffanson talks of this often in The Fat of the Land. Many people report a significant difference between a 60/40 diet vs an 80/20 diet (fat/pro). 60/40 can lead to cramping, diarrhea, nausea, head ache. Another common problem is your gall bladder may not be up to the task of a high fat diet. If you get pains in your gall bladder, try slowly switching from high carb to high fat. High carb diets can lead to gall bladder disease. Yet another problem is that some people just don't like fat. The texture or flavor is a turn off. My wife will gag if she can detect even a small lump of fat. I'm the opposite. I buy fat by the pound, slice it and warm it up when I grill my meat. I love it. To each their own. Yet another problem is that carbs are addictive and ubiquitous so it can be really hard to avoid them. Plus our carb focused food supply doesn't provide a lot of low carb snack options. Also keep in mind that just because a high carb diet is well tolerated, doesn't mean it won't lead to a whole host of chronic diseases. This is well documented in GCBC. Many low carb diets before Atkins started with a fast. This may be better tolerated than " the induction " . Keep in mind that a low carb diet is a fast of sorts. This is why it's effective for weight loss. When you fast, your body switches to ketosis, just like a low carb diet. > > > I wonder about the Atkins " induction " folks.

Guest guest Posted March 4, 2009 Report Share Posted March 4, 2009 Aajonus Vonderplanitz swears by raw meat and fat.

If a person is overweight, maybe the answer is to change the quality of the carbs, not go low carb. The assumption is that all carbs are bad. You can lose weight on a high carb diet with normal activity without any crazy caloric restriction or funky exercise routines. Lots of people aren't going low carb, that is a fact. The good news is that lots of people don't have to go low carb, although some might, but not nearly as many as the low carbers would have you think. My sister has lost 80 pounds over the last year, and she is not a WAPer.

Yes but many low-carbers paint with too broad a brush, no matter how highly they speak of Price's work, they speak with a slanted perspective. Such a perspective is even evident on the WAPF website. As far as I am concerned, Taubes is doing what Shakespeare called " damning with faint praise " when it comes to Weston Price, either that or he is terribly confused. He is adding in my opinion to the " low carb religion " , despite some really good work. Price indeed **observed** that a diet high in animal fats can be healthful, but he also observed the opposite, that a diet high in carbs can be healthful as well. > But almost all the peoples Price studied ate quite a lot of carbs.

Guest guest Posted March 23, 2009 Report Share Posted March 23, 2009 I was reading that two thirds of of carbs in high carb diets convert to fat. It's better to limit carb intake to one third and have fat as the other two thirds. It's also much cheaper on the budget and better for your health Your body will have more energy for it as fat is a better source of ATP than carbs and is the preffered fuel for your mitochondria.

Guest guest Posted March 23, 2009 Report Share Posted March 23, 2009 Your body can store up to 375g of dietary carbs at a time in glycogen. Your body can store up to 333g of dietary fat as intramuscular triglycerides. That is 1500cal of glycogen and 3000cal of intramuscular triglycerides. Say you had a moderate fat high carb diet and you are a 180 pound cyclist and your fuel stores are depleted. You consumed... 60g of fat 800g of carbs 375g of the carbs will store as glycogen 425g of the carbs will store as Intramuscular triglycerides. That 425g of carbs is equivalent to 188g of fat. You are still short 85g of fat and your body's fuel source won't be optimal. That's my example.

Guest guest Posted March 23, 2009 Report Share Posted March 23, 2009 I just threw out some science. The body burns glycogen even with a high fat diet. I think moderate carb high fat is ideal for an active individual. It would be nice to get a chart that shows what types of calories get burned with a high fat moderate carb diet based on various activities at various weight ranges. As an athlete I will still consume moderate carb. If I were sedentary I wouldn't exceed 72-110g of carbs a day. Based on the evidence it would be wise to consume a 2-1 fat to carb calorie ratio for athletics.

They are not obese because they are more sedentary, again the causal arrow points in the other direction. But not all calories are created equal. Carbs raise blood sugar which triggers insulin release. Insulin stimulates appetite and fat storage. Low carb diets keep insulin low, appetite low and fat storage low. Calories restriction causes everyone's metabolism to slow down, this is an adaption for survival. This is why calories restriction (dieting) rarely works in the long term. Exercise stimulates appetite by increasing energy requirements.

I don't think an exception can be made for McDougall. TCD's are not vegan or slightly vegetarian or low in saturated fats. His approach is not a TCD which might explain the trouble those women were having using his diet. I for one cannot eat a high starch vegan diet unless it is loaded with saturated fat. And that is the interesting thing about the TCD groups, while they are low fat overall, they are not low saturated fat and they certainly are not vegan/vegetarian. > Which makes me wonder if the damage done by the SAD can be undone by the > TCD.

I think so, but it would need to be a true TCD and not something like McDougalls. I also think some folks may in fact have to leave carbs altogether in order to heal and then come back to them at a later date. Like all things it will vary from individual to individual. Again, that is why I am a big fan of elimination diets, be it fasting, milk, or meat, because they allow the body to heal regardless of the subsequent macronutrient ratio a person chooses. Others argue that you can heal using starches if done properly. I think everyone has to find their own way. The guy referred to as " the notorious Bruce K " is now extolling the healing powers of a high starch diet, even changing the name of his AV-Skeptics group to the High-Everything Diet. -- " Forget about reading Austrian Economics.

Guest guest Posted March 24, 2009 Report Share Posted March 24, 2009 You just sighted experts saying that the brain and central nervous system utilize 120-130g of glucose a day. That would mean I want to consume atleast that much in carbs. Starches are the best of all evils as they only do one third the immune defense reduction than other types of carbs. I would want to consume more fat for a glycogen sparing effect and quite a bit too as the body uses quite a bit of fat energy everyday. I'd rather not not consume too much protein as it puts a lot if work on the organs and depleted minerals from the body. Most athletes consume way too many carbs. They'd do better to cut almost half and up their fat intake. Yours Truly, Dan Holt On Mar 24, 2009, at 10:01 AM, " lynchwt " <lynchwt@...> wrote: > > I just threw out some science.

You seem to be relying upon false assumptions about fat metabolism that still, unfortunately, inform modern nutritional science despite the fact that they have been decisively refuted for a half century or so. Taubes' book does not just provide yet another dietary scheme brought down from the mountain, but looks at the evidence--and the strength of the evidence-- regarding carbohydrates and separates out the dominant conclusions that evade or ignore this evidence. Relevant here is the notion that carbs are needed to power our muscles and the allegedly harmful effect of low carb diets. The book is exhaustive, but a few relevant excerpts: " From the 1920s through the 1960s, a series of discoveries in the basic science of fat metabolism led to a revolution in the understanding of the role of insulin and the regulation of fat tissue in the human body. This era began with a handful of naive assumptions: that fat tissue is relatively inert (a " garbage can, " in the words of the Swiss physiologist Bernard Jeanrenaud); that carbohydrates are the primary fuel for muscular activity (which is still commonly believed today); and that fat is used for fuel only after being converted in the liver into supposedly toxic ketone bodies. The forty years of research that followed would overturn them all--but it would have effectively no influence on the mainstream thinking about human obesity (p. 382). " There follows a very interesting section about the fluid status of fat reserves, something that tends to be interrupted with obesity and ignored by those warning about the need for athletes to ingest enough carbs. In any event: " There are three distinct phases of the revolution that converged by the mid-1960s to overturn what Bruch called the " time-honored assumption that fat tissue is metabolically inert, " and the accompanying conviction that fat only enters the fat tissue after a meal and only leaves it when the body is in negative energy balance (p. 382). " 1st phase: fat tissues have distinct structures and are in a continual state of flux and are not mere repositories. The 2nd phase involves the Krebs cycle and showed that fats and proteins supply fuel for muscle tissue and that carbs were not the preferred fuel. This research suggested that fat tissues were not a " savings account, " but a " coin purse " for ready use (something that gets interrupted in carb-stimulated obesity, hence the cells are starving and signal the body to eat more and move less). The third phase " established the dominant role of fatty acids in supplying energy for the body, and the fundamental role of insulin and adipose tissue as the regulators of energy supply " (p. 385). " As early as 1907, the German physiologist Adolf Magnus-Levy had noted that during periods of fasting between meals " the fat streams from the depots back again into the blood...as if it were necessary for the immediate needs of the combustion processes of the body. " A decade later, Francis Benedict reported that blood sugar provides only a " small component " of the fuel we use during fasting, and this drops away to " none at all " if our fast continues for more than a week. In such cases, fat will supply 85 percent of our energy needs, and protein the rest, after its conversion to glucose in the liver. Still because the brain and central nervous system typically burn 120 to 130 grams of glucose a day, nutritionists insisted (as many still do) that carbohydrates must be our primary fuel, and they remained skeptical of the notion that fat plays any role in energy balance other than as a long-term reserve for emergencies. " " Among physiologists and biochemists, any such skepticism began to evaporate after Wertheimer's review of fat metabolism appeared in 1948. It vanished after the 1956 publication of papers by Dole at Rockefeller University, Gordon at NIH, and Sigfrid Laurell of the University of Lund in Sweden that reported the development of a technique for measuring the concentration of fatty acids in the circulation. All three articles suggested that these fatty acids were the form in which fat is burned for fuel in the body. The concentration of fatty acids in the circulation, they reported, is surprisingly low immediately after a meal, when blood-sugar levels are highest, but then increases steadily in the hours that follow, as the blood sugar ebbs. Injecting either glucose or insulin into the circulation diminishes the level of fatty acids almost immediately. It's as though our cells have the option of using fatty acids or glucose for fuel, but when surplus glucose is available, as signaled by rising insulin or blood-sugar levels, the fatty acids are swept into the fat tissue for later use. The concentartion of circulating fatty acids rises and falls in " relation to the need " for fuel... " (pp. 385-386). A key point to notice here is the disconnect between what physiologists and biochemists were uncovering about the hormonal regulation of fat and energy and how nutritionists continued to use a very reductive, non-fluid conception of what the body needs from dietary sources. , this reminds me of your modus operandi here, tallying up how much your body " needs " from diet by looking at what body parts (brains, muscles) use during the day, when the evidence suggests that the body is very good at utilizing fat and protein in place of carbs. Of course, it's possible that an athlete may perform better on high or moderate carbs, but there is absolutely no evidence right now that that is the case and lots of suggestive evidence that this is not true. And the point about long-term consequences for athletes is an important one. I used to play basketball 4 hours a day, six days a week, and a high carb, vegan diet seemed to help at the time. But I developed allergies, asthma, and other inflammatory conditions, which I've begun to reverse with a healthier diet. I only play basketball twice a week now, but at high intensity and I haven't noticed any drop off in energy (and an increase in strength) since I cut carbs. None of this says that in a healthy individual whose metabolism has not already been disregulated, that traditional carbs would be damaging. But the key suspect in the host of diseases of civilization seem to be tied to the effect of excessive and/or refined carbs in disrupting homeostatic regulation of metabolism. And there certainly seems to be no evidence that active or athletic people need the amount of carbs you have suggested. Best, Bill Quote Link to comment Share on other sites More sharing options...

Guest guest Posted March 24, 2009 Report Share Posted March 24, 2009 I'm concerned as I like to do high impact and low impact activity. I want top physical performance and based on the research I looked at carb glucose is the best source. What I think I'll do is eat my three meals closer together earlier in the day and let my body go into ketosis later at night. That way I have top performance. My first meal will be at 6AM in the morning, my second at 9:30AM and my third at 3:30-4PM. I'll switch to: 108g of protein a day 221g of fat a day 216g of carbs a day Yours Truly, Dan Holt On Mar 24, 2009, at 2:46 PM, " cbrown2008 " <cbrown2008@...> wrote: > You just sighted experts saying that the > brain and central nervous system utilize 120-130g of glucose a day. > That would mean I want to consume at least that much in carbs. Dan this is a common misconception. The body can make 120g of glucose, given enough protein and fat and glycogen. You do not have to get it all from dietary carb. However, why use gluconeogenesis and making carbs from the glycerol in triglycerides for every single little glucose, when some dietary glucose is okay. That's why most low carb writers allow 50+ grams of dietary carb a day. Connie Quote Link to comment Share on other sites More sharing options...

Guest guest Posted March 25, 2009 Report Share Posted March 25, 2009 What's your opinion about re Adventures in Macronutrient Land showing the people consuming about 3000 calories a dayon average with they ratios being 20% protein, 30% fat, and 50% carbs. On average 110g protein, 150g fat, and 400g carbs. I think people's metabolsims were faster because depression wasn't as wide spread and better quality food was politically correct to eat back then. I was surprised to see their high fat intake too. Yours Truly, Dan Holt On Mar 24, 2009, at 5:10 PM, " lynchwt " <lynchwt@...> wrote: Again, I don't know where you get this, but the evidence does not support it. Quoting Taubes again: " It is not the case, despite public-health recommendations to the contrary, that carbohydrates are required in a healthy human diet. Most nutritionists still insist that a diet requires 120 to 130 grams of carbohydrates, because this is the amount of glucose that the brain and central nervous system will metabolize when the diet is carbohydate-rich. But what the brain uses and what it requires are tow different things, Without carbohydrates, as we discussed earlier (see page 319), the brain and central nervous system will run on ketone bodies, converted from dietary fat and from the fatty acids released by the adipose tissue; on glycerol, also released from the fat tissue with the breakdown of triglycerides into free fatty acids; and on glucose, converted from the protein in the diet. Since a carbohydrate-restricted diet, unrestricted in calories, will, by definition, include considerable fat and protein, there will be no shortage of fuel for the brain. Indeed, this is likely to be the fuel misture that our brains evolved to use, and our brains seem to run more efficiently on this fuel mixture than they do on glucose alone " (p. 456). Taubes then discusses the actual reasoning behind 2002 Dietary References Intakes document that suggested these figures. The stated rationale was that 100 grams of glucose were needed to run the brain _only_ on glucose, but then admitted that this was not necessary. The 130 figure was used to allow a margin of error. This is how these kinds of stated needs get perpetuated. A back of the envelope calculation is done, complete with qualifications, that are then ignored in the final recommendation. Then the figure takes on a life of its own as everyone quotes this without any awareness of the initial context. This is why every time they claim to test low carb diets, they usually have the low carb one have at least 120-130 grams of carbs " for safety, " thereby blurring any distinction with higher carb diets.
