The section most relevant to CNS is 'Anti-Calorie argument #6: Hormones drive fat gain (insulin – blood sugar – carbs = carbs make you fat)'http://www.coreconceptswellness.com/blog/the-sensible-middle-part-1-in-defence-of-caloriesI would like to know peoples' thoughts on this, particularly the summary of:'The death knell in the carbs-make-you-fat and you don’t need to eat less calories mantra are metabolic ward studies – the most tightly controlled studies available and the gold standard when it comes to scientific rigour. As you can see, with scant exception – weight does not waiver based on macronutrient composition.'...that links to this study on macro composition: http://www.ncbi.nlm.nih.gov/pubmed/15867892?ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum%20
I'll take a shot…Couldn't get the full review, but this line stuck out to me in the abstract. "However, a review of studies in which 24-hour energy expenditure was measured did not provide evidence to support a metabolic advantage of low-carbohydrate diets and showed little evidence of a metabolic advantage of high-protein (>25% of energy) diets. Nonetheless, diets high in protein, but either low or modest in carbohydrate, have resulted in greater weight losses than traditional low-fat diets. We speculate that it is the protein, and not carbohydrate, content that is important in promoting short-term weight loss and that this effect is likely due to increased satiety caused by increased dietary protein. It has been suggested that the increased satiety might help persons to be more compliant with a hypocaloric diet and achieve greater weight loss. "Now this is only the abstract so we don't know how they are measuring the metabolism, whether it's CO2/O2 ratio or what...Satiety level probably. But also no mention of specific hormones. You have to ask yourself, what is going on inside the body when you're eating fat and proteins. What is going on when you're eating carbs and protein? What about just fats, by themselves? Some of these studies are flawed. Whenever you read research journals, sometimes the science is flawed on certain points that can be inconclusive in regards to what answers you seek.Also, found this piece that stuck to me..."However, fat will also suppress HSL even when insulin levels are low. This means you will be unable to lose fat even when carbohydrate intake is low, if you are overeating on calories. If you ate no carbohydrate but 5,000 calories of fat, you would still be unable to lose fat even though insulin would not be elevated. This would be because the high fat intake would suppress HSL. This also means that, if you’re on a low carbohydrate diet, you still need to eat less calories than you expend to lose weight."Okay, I'll agree with this statement. If you're pounding down too many calories, essentially you will remain weight stable or cease to lose fat. However, check out this study: http://www.ncbi.nlm.nih.gov/pubmed/20837645 Key points: Trained cyclists on a hypercaloric diet that has been fat enriched, training 4xwk in either a fasted state or fed state. All groups increased in bodyweight, however, the higher fat diet gained only (0.7+/-0.4kg) compared to the CHO group (1.4+/-0.4kg). GLUT4 content was upregulated in the FAT group (+28%) vs CHO (0.05%).What about a higher fat diet (30% above base calories) caused the fat group to gain only so little bodyfat? There are a lot of studies out there, but the application that Keifer has done is in applying them to real world results. I know you're on CNS, but I learn better from pictures, so I took a picture from how insulin in a regular day looks like and compared it to what CBL tries to do...I'll have to do one for CNS later. But see the difference. You spend a lot more time in the catabolic zone for burning off body fat, with a small window to gain body fat, which is inhibited by resistance training.I dunno, maybe I'm off base. But I'll leave it up to someone else to view this topic in more detail.
From the abstract alone the study asserts it is the presence of protein, rather than the lack of carbs, that is the primary driver of weight loss due to dietary adherence on a hypocaloric diet.The area of contention (as I see it) with CarbNite is:A calorie deficit is assumed as a prerequisite for weight loss, and that protein and fats aid adherence to a diet that would otherwise be difficult to stick to, but that this is the limit of the role of fats and protein; It is not the presence of protein and fat that drives weight loss, but adherence to a hypocaloric diet instead.I am interested in why CarbNite works for some people, and why it seems to go wrong for others. To me, this study explains both why it works for some people, and also why it doesn't work for others.Why it works - because high fat and moderate protein can be an easy way to remain in a calorie deficit due to the satiating effect of fat and protein. People may not even know they’re in a deficit because fat and protein can be so satiating. If carbs were not removed then it would not be possible to eat enough satiating fats and remain in a calorie deficit. This is my personal experience too. I simply don’t go to bed hungry any more, but I’m not gaining weight. If carbs were consumed, I would not be able to do this.Why it doesn't work: Because calories still matter. By assuming eating fat and protein aids weight loss beyond dietary adherence, seems to be where people go wrong.As I said, I think CarbNite works – but not for the reasons people think, and where people don’t explore why it works, they over eat and don’t see results.
Maybe we're looking at this both wrong. Maybe both calorie deficit and macronutrient composition are right, but for different reasons. Because metabolism changes calories count to a certain extent; however, metabolism is influenced by thyroid hormones and can be manipulated by the diet and exercise protocols as well (ie. excessive running decreases thyroid hormones, blah, blah, blah). So dependent upon individual metabolism calories in/out would prove correct.Then the influence from different macronutrient contents of diets cause a change the efficiency of metabolism as a whole. This would correlate with high fat-protein diets that are hypocaloric, yet only cause moderate weight gain.This would also play into your other post, about how dropping below 10% bodyfat would cause a change in the metabolism, that would indicate fine tuning your weight loss protocol.
“I feel like my weight loss has started to slow down. Should I cut calories?Absolutly not. (……)Secondly, an ultralow-carb diet causes only subtle changes in the body mimicking starvation while still allowing you toe at ample amounts of food. This preserves muscle while still ahedding unwanted body fat. Cutting calories changes the situation from mimicking starvation to being starvation --as far as the body is concerned. At this point, you will destroy the majority of benefits form using The Carb Nite Solution. Fatl loss slows even more, muscle wastes away, cortisol levels rise and new fat cells may beging growing. Just kep in mind that as you lose body fat it gets harder to lose even more, so your progress will slow, even on The Carb Nite Solution.”1“You dismiss cutting calories as an effective weight loss strategy, But I noticed the included meal plans could be considered low-calorie for some people. Is the Carb Nite solution just a low-calorie diet dsiguise?The included meal plans form the groundwork for your daily nutritional needs and I asume between-meal snacking and aditional food ítems will ítems will accompany Schedule meals; by no means you are expected to strictly adhere to meal plans. Bute ven in the case there is minimal snacking, the average gCarb Nite for dieters consists of a large number of calories—a whole day's worth od calories is eaten in a single night. Therefore, when considering total weekly calories, it becomes difficult to consider The Carb Nite Solution a low-calorie diet.”21. Kiefer, John. (2005). The Carb Nite Solution.
