I recommend Peter Attia's (currently unfinished) series, "The straight dope on cholesterol". He's a surgeon interested in health and fitness. http://eatingacademy.com/?s=cholesterol

I've been doing ketosis for about 6 months, after having done twice in the past. From my heaviest to today over the last 2 years, I'm down 50 pounds.
The data in this post was cool. I found Dr. Peter Addia's analysis to be one of my favorite resources. He's a medical doctor who was an overweight endurance athlete, then began doing ketosis. I appreciated an honest scientific analysis of the benefits and drawbacks of ketosis.

As an aside, I think that our attitude toward insulin from a public health perspective is going to change a lot in the next few years.
barking-chicken · 2015-03-13
You are absolutely right. There was a lot of manipulation that went on with the food pyramid, but a lot of studies in the last 5 years have shown that the relationship that we once thought existed (red meat=bad) is false. There are also well validated studies showing that the nutrition science that has been taught for the last few decades about our relationship with sugar, fat, food in general, and how cholesterol affects our bodies is wrong.
Dr. Peter Attia's "The Eating Academy" (http://eatingacademy.com/) is a great place to learn more about what we are finding out about how certain foods actually affect out bodies.

Exercising is not gonna help you lose weight long-term, you have to change your diet. I would recommend reading up on ketogenic diets.

fulmato, you were hellbanned after your first comment saying "this is bs". Not a great comment, but hellbanning for a single comment is quite extreme. Posting your useful comment here:
On top of /r/keto Dr. Peter Attia has a great blog on this topic http://eatingacademy.com/
It's a great resource for a more scientific explanation of what happens to the metabolism when keto-adapted and on the effects of carbohydrates and more importantly insulin.
mietek · 2013-06-21
Have you actually looked at the studies cited, and checked the fat—protein—carbohydrate ratios used?
For example, this 2009 study used the following ratios to conclude "low-carb" diets aren't better than regular reduced-calorie diets:
20%—15%—65%
20%—25%—55%
40%—15%—45%
40%—25%—35%
http://www.ncbi.nlm.nih.gov/pubmed/19246357
None of these are actually low-carb. The recommended ketogenic ratio is:
60%—35%—5%
Try Peter Attia's Eating Academy for some highly informative reading:

Petter Attia writes about the ketogenic diet in depth [0]. He's an MD, and references studies throughout his writing. They're not always "keto" studies per se, but they are often studies on parts of the keto process. I highly recommend his blog for in-depth keto reading.

Each day:
* Get 80% of your calories from fat.
* Eat less than 25 grams of net carbs (total carbs - fiber content).
Last 4 years experimenting with sustainable weight loss diets, this (ketosis) has been the most effortless and enjoyable method I've found. I feel satieted, I don't have after-meal drowsiness and most importantly, after a few months it's become part my lifestyle, so maintaining it is a breeze.
Happy side effect: I prefer home-cooked food to eating out because restaurant food isn't usually fat heavy.

Sorry that we got sidelined with carbs and diabetes on this, it's pretty off topic. My fault for being inaccurate probably. Please watch this, especially if you have been downvoting me:

Even with heavy glycolytic training, exogenous carbohydrate intake needs are typically overstated.
Peter Attia (along with Volek and Phinney) has done some fantastic n=1 research in this area [1]

>Carbohydrates are, however.
Carbohydrates are in no way essential to a diet if replaced with proper amounts of fat and protein. http://eatingacademy.com/

A great read on this same topic:
http://eatingacademy.com/nutrition/is-sugar-toxic
"What I find frustrating about this debate is that most people yelling and screaming don’t fully define the terms, perhaps because they don’t appreciate them (forgivable) or because they are trying to mislead others (unforgiveable). The wrong question is being asked. “Is sugar toxic?” is a silly question. Why? Because it lacks context. Is water toxic? Is oxygen toxic? These are equally silly questions, I hope you’ll appreciate. Both oxygen and water are essential for life (sugar, by the way, is not). But both oxygen and water are toxic – yes, lethal – at high enough doses."

For those of you who still believe it's OK or even good to eat a lot of saturated fats, if you look at the studies it's not much of a controversy:" Whether saturated fat is a risk factor for cardiovascular disease (CVD) is a question with numerous controversial views.[1] Although most in the mainstream heart-health, government, and medical communities hold that saturated fat is a risk factor for CVD, some hold contrary beliefs." https://en.wikipedia.org/wiki/Saturated_fat_and_cardiovascular_disease…
Anecdotally, I've read 50% of people who go on Keto see a huge 2-3x increase in triglycerides and LDL-P (Particle count as measured by NMR) - the #1 risk factor for cardiovascular disease. More LDL particles bouncing around in your arteries = bad. People with a condition that makes them break down more LDL have much less artheroscleriosis:
http://www.nejm.org/doi/pdf/10.1056/NEJMoa054013
People with a condition that makes them have more LDL particles get more artheroscleriosis: https://en.wikipedia.org/wiki/Familial_hypercholesterolemia
Read Peter Attila's exposition that goes in detail (eating cholesterol is fine though): http://eatingacademy.com/nutrition/the-straight-dope-on-cholesterol-pa…
Keto could work, but it's a hyper-pro level high-risk diet requiring frequent blood work and still avoiding saturated fats keeping them primarily monounsaturated which makes it very hard to follow. Plus it sucks for weightlifting..
Surprisingly, very low fat diets might be…
voidlogic · 2015-12-03
I mean you no offense, but to me it sounds like your understanding of nutrition science is 10 years in the past.
I do want to point out naturally occurring transfat has very different properties than the artificial common forms. I have never seen a well designed study show a low-fat diet to be superior to a high-fat-moderate-protien-very-low-carb one (usually referred to as VHFLC). I'd be interested if you know of any.
It is no longer generally accepted that dietary cholesterol is dominate factor unless you have mutation such as some of the PCSK9 mutations. Your body syntheses much more cholesterol everyday than you actually eat. The latest US government dietary guidelines has drastically shifted its position on cholesterol, write-up: https://www.washingtonpost.com/news/wonk/wp/2015/02/10/feds-poised-to-…
We have since learned many things such as the importance of HDL/LDL ratio as being predictive over just LDL for example.
This is a very complex topic and I would recommend this series written by a MD: http://eatingacademy.com/nutrition/the-straight-dope-on-cholesterol-pa…
This is a 5 part series befitting the complexity of the issue at hand.

Disclaimer: I am not a doctor, just someone who is curious about how the body works on a high level.
To better understand cause and effect, a question that Peter Attia asks is that, do children eat more and grow (gaining weight as they age), or is it because they are growing that they eat more? Nutrition turns out to be a lot more complex than just calories in and calories out. It looks like that is a manifestation of something deeper, like growth hormones triggering a different type of metabolism.
He asks the same question about obesity. Do people get fat (elevated number of triglycerides stored in the fat cells) because they are eating more than expending energy? Or, are they eating more because of hormonal imbalances? He (along with many other doctors) suggest that it is actually the effect of insulin that causes the body to be conservative with the expending of energy. Insulin resistance also leads to diabetes, which is strongly correlated with obesity. So the hypothesis is that it is out of control insulin (due to sugar intake, HFCS, simple carbs, prevelant in american diet) that is the cause for the obesity epidemic, and not just less exercise (although exercise can be used to eliminate the excess glucose in the body which triggers the insulin response).
Here are some of his talks:

Steve Phinney and Jeff Volek have done a lot of research into high performance athletes using a ketogenic diet (see, for instance, The Art and Science of Low Carbohydrate Performance[1]). Extreme endurance athletes are using ketogenic diets as a tool to smash records in ultramarathon running[2].
Nobody needs carbohydrate. That doesn't mean carbs are necessarily bad, but the long-time trope that you have to have them if you want to move further than your couch is just silly and has long been disproven (if, by nobody else, hunter-gatherers who had gone days without food while running down a kill).
Phinney and Volek have found interesting things about fat and high-intensity exercise:
* Fat utilization in keto-adapted individuals that is, literally, re-writing textbooks. Levels of fat mobilization that have never been seen in laboratories is being recorded. This likely has a genetic component, what I would consider the opposite of the multiple copies of the amylase gene that highly carb-tolerant people seem to have.
* Fat requires less oxygen to utilize, leading to less lactic acid, less muscle tissue damage, and faster recovery.
* Keto-adapted athletes are much more efficient in their use of their glycogen stores, using less when passing 70% VO2-max and replenishing supplies faster. They do not store as much glycogen as carb-burners, so the net effect winds up being about the same amount of power from glycogen between carb and fat burners.
That doesn't mean there are no…

I think that's just ketone esters. That actually sounds pretty pleasant compared to the descriptions I've heard of earlier ketone esters: http://eatingacademy.com/personal/experience-exogenous-ketones
xriddle · 2016-05-02
Do you have a scientific source for these claims? Dr. Peter Attia's personal research seems to claim otherwise.

The Warburg effect is a metabolic pathway involving anaerobic burning of glucose. When cells consume fats instead of sugar it must be aerobically. Burning glucose aerobically is much more efficient than doing so without O2.
The belief is that this means that low carb diets should be a good preventative for cancers as they remove the metabolic pathway needed by the cancer cells as there isn't enough glucose for them.
EDIT: Here is an article that goes into this in a bit more depth: http://eatingacademy.com/nutrition/way-exploit-metabolic-quirk-cancer

It would seem so:
http://eatingacademy.com/cholesterol-2/random-finding-plus-pi
I think that's essentially what a diagnosis of familial hypercholesterolemia means.
Likewise people seem to vary widely in their ability to handle high carb diets. I guess a cookie cutter approach doesn't really work across the board.

Maybe in extreme cases, read this docs blog, he has done keto for a long time but i noticed he has now changed up and only does it at certain times. Also he has a lot of stuff on keto. http://eatingacademy.com/personal/actually-eat-part-iii-circa-q1-2014
