Is overeating carbs worse than overeating on an LCHF diet?
The result of 5,800 calories of junk food a day
Sam Feltham carried out an experiment a few months ago that caught a lot of attention. For three weeks he pigged out on low-carb low-carb foods, 5,800 calories a day.
According to simplistic calorie counting, Feltham should have gained 16 lbs (7.3 kg). But in reality, he only gained less than 3 lbs (1.3 kg).
Now Feltham has repeated his experiment with exactly the same amount of calories, but from carbohydrate-rich junk food. On the same amount of calories he gained more than five times as much weight: almost 16 lbs (7.1 kg)!
The difference in waist circumference was even more significant: 5,800 calories of LCHF food for three weeks reduced his waist measurement by 1 1/4 inches (3 cm). The same amount of junk food led to a 3 1/2 inch (9.25 cm) increase in his waist. And you can see the difference visually.
A picture is worth a thousand words
Above are photos from the junk food experiment. Below, the LCHF experiment (with the same amount of calories) as a comparison:
Conclusion
A calorie is not a calorie. This has already been proven in study after study, but Feltham provides us with a nice real world illustration.
Here’s his final report: Day 21 Of The 21 Day 5,000 Calorie CARB Challenge
What do you think about the outcome?

Why don't you post the actual refuting statement(s) instead of a citation that I can't access.
"Chapter 1, The Fat Loss Bible by Anthony Colpo. He analyzes about two dozen of these studies with full references. You can look them up individually yourself."
Such a waste of everyone's time.
You are seriously taking the position that you have never read the basic functions of insulin as available in ANY biochemistry textbook and are repeated on this blog (usually for the benefit of folks like you) every couple of weeks? Functions which YOU dispute because Stephan is pissed at being upstaged by a "journalist"?
Above you made this non-specific statement to justify why you think chronically raised insulin is NOT the reason why people overeat...
"I believe LCHF works because of the effects of increased protein, but also it lowers the variety and overall palatability of the foods enough to prevent overconsumption. I do not think insulin causes people to eat more, if anything it has the opposite effect. I think people eat too much because of the brain's reward center coupled with genetics, the body's homeostatic system (ie. settling point), and the modern western food environment"
So once again I am asking for examples of foods that meet all these criteria but keep insulin out of the mix. No sugar or refined starches allowed. Name me some "highly palatable" or "high reward" (or whatever SG is calling it this week) foods that do NOT quickly and significantly raise insulin levels. Examples of food that are generally overeaten -- not just your own personal likes and dislikes.
Should be easy enough for you if insulin is not a factor at all, or at least not the main one. Even easier if, as you say, insulin suppresses appetite... food that doesn't raise insulin ought to be more appetizing right?
Straightforward challenge with the expectation of a straightforward response.. no prevarication or beating about the bush. Do that and maybe I will have to eat my words.
I do not see how the basic functions of insulin in any way prove that it causes obesity. What matters is not only what occurs right after carbohydrates are consumed, but what about during the hours of the day that you aren't eating? Fat is being released and oxidized continuously regardless of whether you eat carbohydrates are not.
Consider this. When you eat a LCHF diet, you are storing far more dietary fat in your fat cells than if you eat a high carb diet. That fat is almost all stored after consumption. It doesn't even require insulin, it is stored by ASP. Why is this not the cause of obesity? Again because fat is released and oxidized continuously. As far as the fat stores go, its the net change in energy that determines whether obesity occurs.
Its perfectly reasonable to suggest that the brain's reward system is overloaded by the environment, causing our body's homeostatic system to become less effective at regulating our intake, leading to obesity through excessive calorie consumption.
pork rinds, maybe
Anyways I don't see how this is meaningful anyways. In order to eat a diet with a low insulin response, you need to avoid protein foods as well as carb foods. You'd basically be eating all fat, which sounds like a horrible diet. Given my stance that food variety within a meal heavily influences its palatability, I would say it'd be nearly impossible to even consume a highly palatable diet that is low in insulin response.
Here's a question for you. Since refined carbs are often blamed for causing obesity due to their fast absorption and insulin response, why is it that eating refined carbs and fats together does not prevent obesity by slowing down that absorption of nutrients?
I asked for examples of "foods that do NOT quickly and significantly raise insulin levels"
Yes protein raises insulin levels but not quickly and significantly.
You have still to respond to Murrays narrative above about why he thinks (and I agree) that glucose is not the "preferred" fuel. I guess because by ignoring that comment you can feel free in future to use that same line again.
You asked "why is it that eating refined carbs and fats together does not prevent obesity" -- do you think that because fat does not raise insulin it somehow suppresses its release in response to the sugar and refined starches?
By your reasoning insulin suppresses appetite so how is it that every single goddam "highly palatable" foods RAISES insulin levels quickly and significantly... pure coincidence?
Why is it that the the most widely recognised cause of obesity is basically just flavoured sugar water? No fat or protein or anything else to give it "variety".. and yet it seems some teenagers (for example) can drink it by the gallon per day?
Why is it the Professor Lustig has a study where children where "primed" with soda before a buffet-style meal but instead of naturally eating less (because they already had all those calories from the sugar water, plus your supposed insulin appetite suppression... right?), or even just the same, instead they ate MORE than the controls? Same foods, same "variety" and yet something had increased their appetites for it.
The fact that we can all easily list foods which are generally overeaten and contain significant amounts of sugar and/or refined starches (some are ONLY sugar and/or refined starches) but you struggle to even find one that is only fat and/or protein speaks volumes for your ideas and imagination.
Surely you have heard of Occam's razor grinch? Instead you reach for some vague, ill-defined, complex "multi-factorial" solution.
The answer is staring you right in the face.
And by the way... if you quote someone, do them the courtesy of quoting it "as is".. without editing, unless you clearly show what you have edited. Unless that is just another part of your "game".
So why so much selective pressure for pursuit hunting. The food, apparently. So we evidently evolved from primarily carb diet to primarily fat and meat. Evidence suggests early hominids fed off carcasses left by large cats, using stones to crack open bones and skulls for precious marrow and brain. The omega 3 rich brain helped hominid brain development, and stone selection evolved into tool craft. The digestive tract shortened, allowing better running, and weaning off prolonged fermentation of vegetable matter as part of digestion, out-sourcing that work to the ruminants. We lost fructose enzyme.
So we gained a host of adaptations for fat heavy diet, including metabolic. We evolved the large brain in the context of ketones. It was not under selective pressure to withstand heavy loads of sugar and insulin (witness current research on carbs, insulin and cognitive decline with age).
Where did the fat metabolism come from. Back to Nietzsche, genealogy of morality, on how evolution takes old forms and commandeers them to new purpose. Kenyon identifies two modes, grow-reproduce-die and conserve-repair. Sugar and insulin trigger the former, their absence the later. This goes back as far at least as worms. In bears we see hibernation--the ultimate LCHF diet. It seems early hominid evolution commandeered hibernation metabolism to evolve a metabolic state suitable for pursuit hunting of fat and protein animals. The glycogen capacity of the liver was commandeered from fuel reservoir to safety buffer. But, as Lieberman observes, we did not evolve to have perfect health. And we were carbovores not long before. So the fat metabolism is great for endurance, repair and brain, but it is not perfected. Also, we have residual carb metabolism, in a sense giving us the best of both, but vulnerabilities with both.
The story continues with high carb agrarian society with its remarkable benefits in terms of enabling more complex civilization and adaptations to tolerate grains and dairy. Lactose tolerance has been identified as the most highly selected genetic change in the past 10,000 years. I just read a report on research showing Québécois are genetically distinct, having lived as a distinct society for 400 years with large families. Plainly many people tolerate grains, dairy and high-carb well. Québécois cuisine is delightfully enhanced with maple syrup and artisan cheeses. But many in the world do not.
So it is misleading to speak in terms of ideal diet patterns without accounting for strengths and weaknesses. Keto is not starvation. It is highly sustainable and is an advantage for endurance. Sugar seems to give burst advantages, drawing on more primordial metabolic pathways in the cell, but at some cost. It is a performance enhancing drug in a lot of ways. I used to think which you drew on most and trained for depended on the sport, but now I see Kobe Bryant has gone grass-fed beef and butter, and the Lakers generally have gone low-carb. So apparently it can be managed. High performance in the short term, however, does not imply long-term health.
I wonder to what extent the Hatfield and McCoy differences between the low carb and carb worlds reflects different positions on the evolutionary pendulum swing among individuals. I have to say I find I risible to claimLCHF is not highly palatable. Almost every LCHFer I know is a foodie.my daughter is away as a freshman at a US university and is pining for the meals she had at home. So the carb-centred fare (at a US university) is markedly less palatable for her. Cheque a son gout, a québécois might say.
I was using the term "highly palatable" as it applies in the "food reward" hypothesis.. so far as I can tell this is circular and means food which tends to be overeaten*. I agree completely that my LCHF fare is very tasty, varied and nourishing. Sometime I even forget how good it is until I have to travel for my work and eat out at restaurants.
*I realise that proponents of this hypothesis will vehemently deny the circular nature of this definition but when pressed they "uumm" and "aaaah" and seem unable to come up with anything more specific.
and lastly... http://www.youtube.com/watch?v=HPnJM3zWfUo
So much wrong with your arguments. First off, sugar water does not cause obesity by itself. It causes obesity because it means you are consuming empty calories on top of your meals with no added satiety. This will only cause you to become obese if you are genetically predisposed and homeostatic system cannot adapt. Otherwise your body will adjust by decreasing your appetite for the next meal(s). There are studies demonstrating if you take two meals with equal macro-nutrient composition and make one more palatable than the other, the subject will eat more of the palatable meal.
And correlation does not equal causation as you all would like to remind us. If overconsumed foods are associated with high insulin levels, that does not mean the insulin levels are causing the overconsumption.
Occam's razor. If it applied here, then there wouldn't be billions of high carb eaters on the planet that do not have a weight problem.
Here's a question for you. What causes a metabolic healthy obese person to be obese? Is it insulin or something else?
But when all else fails you fall back on the same strawmen:
I have literally lost count of the times you have made your comment based on the false premise that you say the Carbohydrate->Insulin Hypothesis states: ANY and ALL carbs will make a person immediately ravenously hungry and unable to stop eating. ANY level of raised insulin will do the same.
How many times have you been reminded that this is just not so? Oh sorry you only ASK the question never answer them.. my mistake :-P
Rephrase your question. Keep it realistic (that one may be hard for you) and make the food as bland as you like BUT you have to be using sugar and/or refined starches. Do you think baked potatoes are sugar or refined starches??
Here's a tip if you want bland.. try the glucose tablets they sell for Diabetic Hypoglycemia emergencies at pharmacies. Who knew that pure glucose tastes like chalk!
I guess Sam Feltham's n=1 was not realistic enough for you.... so you had to up the ante with a concentration camp scenario. VERY real world!

Abstract
The role of very-low-carbohydrate ketogenic diets (VLCKD) in the long-term management of obesity is not well established. The present meta-analysis aimed to investigate whether individuals assigned to a VLCKD (i.e. a diet with no more than 50 g carbohydrates/d) achieve better long-term body weight and cardiovascular risk factor management when compared with individuals assigned to a conventional low-fat diet (LFD; i.e. a restricted-energy diet with less than 30 % of energy from fat). Through August 2012, MEDLINE, CENTRAL, ScienceDirect, Scopus, LILACS, SciELO, ClinicalTrials.gov and grey literature databases were searched, using no date or language restrictions, for randomised controlled trials that assigned adults to a VLCKD or a LFD, with 12 months or more of follow-up. The primary outcome was body weight. The secondary outcomes were TAG, HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), systolic and diastolic blood pressure, glucose, insulin, HbA1c and C-reactive protein levels. A total of thirteen studies met the inclusion/exclusion criteria. In the overall analysis, five outcomes revealed significant results. Individuals assigned to a VLCKD showed decreased body weight (weighted mean difference − 0·91 (95 % CI − 1·65, − 0·17) kg, 1415 patients), TAG (weighted mean difference − 0·18 (95 % CI − 0·27, − 0·08) mmol/l, 1258 patients) and diastolic blood pressure (weighted mean difference − 1·43 (95 % CI − 2·49, − 0·37) mmHg, 1298 patients) while increased HDL-C (weighted mean difference 0·09 (95 % CI 0·06, 0·12) mmol/l, 1257 patients) and LDL-C (weighted mean difference 0·12 (95 % CI 0·04, 0·2) mmol/l, 1255 patients). Individuals assigned to a VLCKD achieve a greater weight loss than those assigned to a LFD in the long term; hence, a VLCKD may be an alternative tool against obesity.

Abstract
Very-low-carbohydrate diets or ketogenic diets have been in use since the 1920s as a therapy for epilepsy and can, in some cases, completely remove the need for medication. From the 1960s onwards they have become widely known as one of the most common methods for obesity treatment. Recent work over the last decade or so has provided evidence of the therapeutic potential of ketogenic diets in many pathological conditions, such as diabetes, polycystic ovary syndrome, acne, neurological diseases, cancer and the amelioration of respiratory and cardiovascular disease risk factors. The possibility that modifying food intake can be useful for reducing or eliminating pharmaceutical methods of treatment, which are often lifelong with significant side effects, calls for serious investigation. This review revisits the meaning of physiological ketosis in the light of this evidence and considers possible mechanisms for the therapeutic actions of the ketogenic diet on different diseases. The present review also questions whether there are still some preconceived ideas about ketogenic diets, which may be presenting unnecessary barriers to their use as therapeutic tools in the physician's hand.
Also why wouldn't baked potatoes be a problem, as they do have a high glycemic index?

In summary, there are strong epidemiologic data showing that malnutrition is a common symptom of amyotrophic lateral sclerosis both in humans and in mice and may contribute to disease progression. There is also epidemiologic evidence that increased dietary fat and cholesterol intake might reduce the risk of amyotrophic lateral sclerosis and the rate disease progression. Finally, data from animal studies strongly suggest that increasing dietary intake of fat ameliorates disease progression. However, determining whether amyotrophic lateral sclerosis patients should be treated with a high-fat or ketogenic diet can be based only on randomized double-blind placebo-controlled interventional trials.

Abstract
The very-high-fat ketogenic diet can worsen lipid levels in children with pre-existing hyperlipidemia by increasing serum lipoproteins and reducing antiatherogenic high-density lipoproteins. A retrospective chart review of 160 children treated with the ketogenic diet from September 2000 to May 2011 was performed. Twelve children with pre-existing hyperlipidemia were identified. Lipid levels including total cholesterol, low-density lipoprotein, triglycerides, high-density lipoprotein, and total cholesterol/high-density lipoprotein were measured pre-diet and at 3, 6, and 12 months of treatment. During treatment, there was a significant reduction in mean total cholesterol, low-density lipoprotein, and total cholesterol/high-density lipoprotein. Total cholesterol and low-density lipoprotein were normalized in 8 and 7 children at 6 months; and 9 and 9 children at 12 months respectively. At 6 and 12 months, tot cholesterol/HDL ratio was normalized in 5 and 7 children respectively. Diet modifications were made to achieve healthy lipid levels. By extrapolating the data, it suggests lipid levels can be controlled in children and adults with ketogenic diet treatment.
Quite apart from the absurdity of the scenario you presented, baked potatoes are real whole food.. they are NOT sugar or refined starches. While someone like myself, whose glucose tolerance is now shot, could not tolerate them, that is not to say that they need to be avoided by everyone. Why is that such a tricky concept for you?
They way these facts need to be repeated time and time again for you, leads me to only two possible conclusions: either you truly are this ignorant or incapable of grasping basic principles, or you are a troll who is being consciously obtuse.. perhaps for financial gain. I don't know and I don't care. You are a waste of valuable time in either case.
Also if I was a diabetic, I would've stayed on a low carb diet. Doesn't mean I think the science behind it is right or that the benefits you receive as a diabetic are the same as someone who is not.

As a Nietzsche admirer, you may want to consider one of his more meaningful passages:
"The hermit will doubt whether behind every one of his caves, there is not, must not [always] be, another one, richer, deeper, and more comprehensive in its meaning than the one before it, and behind the second yet still another one, richer, deeper, and more comprehensive in its meaning than the ones before it and which serves as the grounds for all those prior [and which finally] shakes even the idea of grounds."
Religion, i.e. LCHF ideology, and Nietzschean critical intellect are strange bedfellows.

Processed food is not that good for anything!
I wonder.. why should anyone eat processed food??
Must be a contraceptive goal by doing that!?
This was a cross-sectional study...one of the weakest designs available i.e. only associations can be tested not cause and effect. It's extremely weak evidence even against processed meat.
As with so many other things there is "bacon" and then there is "bacon". I have no health concerns with the way I am eating... and I seriously doubt that sarcastic comments from an anonymous internet troll are going to convince me otherwise.
Its dry salted and smoked.. its real bacon!
Considering that so much of LCHF is based in science and critical thinking, I find it very gratifying when the naysayers reach for this disingenuous characterisation of it as an "ideology". This just convinces me even more that they have no valid response to the scientific basis for LCHF and are left futilely, grasping at rhetorical straws.
there are two kinds of naysayers - those who have not tried it - and those who have tried and failed
While I disagree with much of Evelyn's comments here, particularly, her predictable distasteful mannerisms/language, you might actually learn something, presuming such willingness exists.....

Hi Andreas, Sometimes ranting is helpful. It got your attention didn't it? So I presume based on that report you will now be posting articles promoting the traditional Mediterranean diet. I hope so!
http://journals.cambridge.org/...
Speaking of helping people, however, how does it help to continually misinform people? I don't think that is helpful.
http://a.disquscdn.com/uploads/mediaembed/images/656/6231/original.jpg
The original Mediterranean Diet may be thought of as having eight components:
1. High ratio of monounsaturated to saturated dietary lipids (mainly olive oil);
2. Moderate ethanol consumption;
3. High consumption of legumes;
4. High consumption of non-refined cereals, including bread;
5. High consumption of fruits;
6. High consumption of vegetables;
7. Low consumption of meat and meat products:
8. Moderate consumption of milk and dairy products.
Fish intake is also a desirable characteristic of the Mediterranean diet, but has depended on the proximity to the sea.
Andreas Eenfeldt carbsane • 4 days ago
Evelyn,
Sure. A traditional Mediterranean diet, like any traditional diet, has many benefits compared to processed Western junk food.
I share the best information I can. Any possible "misinformation" is of course unintentional and solely based on imperfect knowledge on my part.

Why do you call LF diets criminal and even perpetuate the nonsense that is Feltham's "low fat" experiment that made him fatter? No intellectual honesty there I'm afraid.
I fail to see where many that promote LF -- like McDougal, Fuhrman and others are promoting refined garbage foods.
.
Cereals and bread are part of the Mediterranean diet that has a proven track record and is far lower in fat than the unproven macro ratio of fat you promote.
Unproven? - it is proven by my personal experience of over 7 years. It saved my father's life and made him robust and healthy out of really sick man. It is proven by the health of over 20 of my close friends who follow very low carb high fat (animal fat) diet for many years. LCHF diet changed our lives for better beyond our wildest expectations. My friends and I do not need studies, analysis, comparisons showing that say '...mediterranean diet lowers the rate of heart diseases by 10%....". I work in scientific field, I know (as many who read this blog I am sure can attest as well) what can be done with statistics, especially when it comes to nutritional research. No amount of statistically valid data published in Nature showing that saturated fat is going to kill me, will make me abandon my LCHF diet - because my long, PERSONAL experience tells me otherwise. By the way I presented my experiences several times on this blog previously. What is it that you vegans do not get it?.
Willingness to learn? Me? Always open to convincing new evidence, especially if it relates to my somehow killing myself with my diet -- despite all my personal evidence to the contrary. A person would need to be pretty brain dead not to have a vested self-interest in their own health don't you think? Should I ignore the evidence from all my health markers that are relied on for every study out there... all on the word of some anonymous twit on the interweb?
Speaking of which: if you have been reading my comments (and although you skulk around anonymously you seem to think you know me) you'd be well aware by now that the last person I would turn to for advice, is that shrieking harpy Carb Insane AKA Evil-Lyn.
There is no evidence whatsoever that a Mediterranean diet is healthy because of cereals and bread or lower saturated fat consumption.
http://rawfoodsos.com/2010/01/20/my-current-diet/
regimen - to be most beneficial in terms of bio-markers and overall feeling of good health. With this way of eating, I have lowered my A1c levels to the high 4 range, blood pressure, weight, uric acid levels, and CRP, last measured at 0.8. I eat limited amounts of animal protein and fats. I do not eat grains. LCHF is one option and perhaps a good one, but it does not come without risks. There are other routes to health and disease reversal.
http://www.youtube.com/watch?v=vG3V22cLUF0
2. The simple fact is that no one knows the long term health effects of LCHF. What is known however is that replacing saturated fat with monounsaturated ones, olive oil, nuts, avocado, etc.. have tremendous efficacy in lowering levels of lipoproteins, which, as Dr. Dayspring has noted, is perhaps the best predictor of CVD within our current technology.
http://www.youtube.com/watch?v=an6L9VY0v8A.
For those interested, Dayspring has counseled Jimmy Moore directly on his LLVC blog to 1. dramatically lower his saturated fat intake 2. consider statin therapy in lieu of JM's astronomical lipoprotein levels.
Replacing saturated fat with other fats or reducing saturated fat intake have been tremendously ineffective in lowering CHD, cardiovascular and total mortality. These endpoints matter, changes in surrogate markers such as lipoprotein levels do not.
Dayspring promotes saturated fat restriction despite a total lack of evidence that saturated fat is harmful, overestimates the benefits and underestimates the harms of statins and thinks that ezetimibe is an effective drug even though it has miserably failed in every trial to date. IMO Dayspring is not credible.
List these risks and cite RCTs to back up your claims. Otherwise these are just empty words.
"2. The simple fact is that no one knows the long term health effects of LCHF."
Or did you just contradict yourself there? What? You mean you don't know if there are any long-term risks of LCHF?
Meantime ALL my health markers are significantly improved since eating LCHF. And by the way, I am in my mid-50s and in better health that I have been since my late 20's. When should I expect all your doom prophesies to kick in exactly?
And then you go on to promote this quack Gabriel Cousens and still have the gall to call me a zealot?!? Z.M. If you thought Dayspring lacks credibility, you might look into this charlatan as well.
Tell you what.. I'll stick with Dr Eenfedlt.. he gives good practical advice, grounded in science.
No, it's because they're carbohydrates with no other significant nutrition. The difference between 50 and 75 GI isn't worth getting excited about.
So how does that make them fattening? Should mixing these refined starches with healthy fats add nutrition and make them less fattening?
If there is still sufficient sugar and/or refined starch to spike the BG and stimulate insulin, then the additional dietary fat will be even more readily stored.
Remove the dietary sugar and/or refined starches, then the picture is quite different.
How many times a day do you test your BG? How much do you know about what different foods and daily activities do to your BG, how quickly and by inference, your insulin levels?
The diet of the top level is high carb moderate to low protein and low fat. The result is weight gain and higher body fat. The next (Not top tier) eat a higher carb diet and hve an even higher body fat content.
30 years ago one might have question this ; but the SAD the average american eats is more and mor Sumo like and the results in looks, body fat, and biomarkers support a high carb diet is the root of he problem.

I asked Feltham a while back if he kept track of his body fat %, as weight itself isn't a very accurate indicator. No response.
However... the impact of hormones especially insulin and it’s associated fat storage when eating/not eating carbs is very significant, as this study strongly shows (assuming his calories were accurately and scientifically measured independently and not self reported, as we all know you feel fuller with LCHF and can easily overreport what you eat, and exactly the opposite for high carb diets).
It’s been my observation in closely following and moderating several and various keto FB groups over the last 3.5 years that most men usually do not need to think about calories when eating keto. They almost all seem to naturally eat to a deficit and lose weight easily. Women, especially women over approx 30 years old, and especially after being on keto medium/long term, mostly do not naturally eat at deficit, and deficit often becomes quite hard to achieve, and weightloss stalls, and they find they must carefully watch count and restrict calories in order to lose. Even while in ketosis yes, especially as they trend towards goal weight (say with 10kg more to go).
This I think could be due to damage/changes to older women’s metabolism due to frequent previous dieting, or more likely I think is at least partly due to the very different hormones between men and women.
I’d love to see this study repeated with both women and men under very strictly controlled conditions.
