Let me start by asking you a couple of questions. Let's start with this one: What happens if you permanently take all protein out of your diet? Answer: You die. Simple enough. Here's another one: What happens if you permanently take all fat out of your diet? Answer: You die. Hmm. Just a few more: What happens if you permanently take all carbohydrates out of your diet? Answer: You don't die... That's interesting... Last one, I promise: What adjective will you see in front of the word "fat" and "amino acids", that you never see in front of the word "carb"? Answer: "essential". Fact: Never has there been, and never will there be such a thing as an "essential carb". So what is a ketogenic diet?A ketogenic diet is when an individual maintains a state of ketosis. To put it simply, a state of ketosis is when the body predominantly relies on fat (ketones), rather than carbs(glucose) for energy production. This is accomplished through restricting carbohydrate consumption. But I Want My Carbs Damnit!Of course you do. So do I. But what do you want more; Carbs or six pack abs year round? A breakfast of lemon cakes and sugar cookies, or healthy cholesterol levels? For me; I much prefer the long term satisfaction I receive from looking and feeling good, than the short lived instant gratification I get from porking out on Poptarts and Doritos. Isn't A Calorie Just A Calorie?If you truly believe this, then I'm sure you won't mind performing a little experiment for me... For one year, I want you to eat nothing but oreo cookies and cake frosting. Hell, you can even dip your oreo cookies in the cake frosting if you want. Just be sure to keep your calories at or below maintenance. Then give me a call when you're diabetic and your toes are falling off, and let me know how that's workin out for ya. Will you lose weight if you restrict calories? The law of thermodynamics has us believe that's true. And in terms of sheer weight, I believe there is some truth to that. But what is weight? Weight is simply the force you exert on the earth due to gravity. And as far as I'm concerned, weight is irrelevant. Who would you rather be: A guy who is 185lbs at 7% bodyfat or a guy who is 150lbs at 20% bodyfat? If you care only about weight, then you'd pick the second option. But in any mirror and through any normal person's eyes, the first option will always look a lot heck of a lot better. Same thing goes for females... A female who weighs in at 135lbs but only has 10% bodyfat will always look and feel better than a female who is 120lbs at 24% bodyfat. Scales lie. Mirrors don't. And in terms of body composition, a calorie is certainly not just a calorie. Let's break this down even further... When you eat carbohydrates you will inevitably raise blood glucose levels. When blood glucose levels rise, insulin is released. Insulin is an incredibly potent anabolic hormone, and is the main inhibitor of lipolysis which is the breakdown of stored fat. In order for glucagon to be released, which is a catabolic hormone responsible for breaking down stored fat to be used as energy, blood glucose levels must be substantially decreased. Insulin and glucagon are like day and night; they can not co-exist. What I'm saying is that being fat is not just about eating to many calories. It's more about having continuously elevated levels of insulin. In the long term, this is known as hyperinsulinism, and is one of the main causes of obesity and insulin resistance. Controlling insulin levels in the long run is the golden ticket to staying lean, and there is no better way to control insulin levels than by following a high fat ketogenic diet. Ok, so far this makes sense...So how do you do it?Getting into a ketogenic state is not easy for a lot of people. This is because of the dreaded adaptation that must take place; and unfortunately, this adaptation period can be longer for some than others. So realize that going into this, you either have to be fully committed or it won't work. This is not a yo-yo diet. This is a lifestyle. There is no point suffering through three days of an incredibly low carb diet trying to get into a state of ketosis, to only ruin it by binging on a bag of peanut M&M's and cinnamon raisin bagels; as this will only set you right back to square one. You see, the adaptation period can be quite painful for some, because it is not only your body that must switch over from primarily burning glucose for fuel to using ketones, but your brain as well! So expect to not feel your greatest the first couple days ( for me it wasn't all that bad, I just felt a little lightheaded and had an odd craving for baby corn?...), but realize this is normal and it will not last forever. I got through it, and so can you! Because once you have reached ketosis, you will feel fantastic! You're energy levels will be consistent throughout the day and you will also notice that your hunger will also stay in check. You just have to suck it up and rough it out for a few days that's all... Now it's time to answer the big questions... What to eat? The answer is quite simple. You will be eating a lot of...prep yourself, this may scare you...FAT! That's right, not a low carb/high protein, but a low carb/high fat diet is what is going to lead to the most substantial amount of fat loss. Fat is not the enemy. It never has been. Yet fat has un-rightfully received one of the worst reputations in nutritional history. Well, it's time to wipe that slate clean. Carbs are the true enemy and they must be destroyed. Here is Dr. Greg Ellis. He is going to tell you that fat is not bad for you and why you should not just eat a high protein diet. I suggest you listen to him. Thank you Dr. Ellis. Now I personally like to keep my fat around 50-60% of my calorie intake. This has worked best for me. Obviously everyone is a little different, so experiment with the ratios and see what works best for you. Protein is around 30-40% and carbs are around 10-15% Here is what I eat a lot of: Extra-Virgin Olive Oil-EVOO Nuts and Seeds Cheese of all shapes and sizes Natural and preferably organic peanut and almond butter Fish of all varieties Organic eggs (these are always organic for me as I often eat them raw) Poultry Pork Fibrous Veggies Red meat of all varieties (preferably organic) Avocados Whole Raw Milk By no means is this list exclusive. The Benefits of a Low Carb LifestyleAlright, alright, already! I know I've kept you in suspense long enough. And I know! What would this post be without one of my famous, semi-awkward/semi-nude pics of myself? That is the number one reason that I opt for a low carb lifestyle. As it is the only way of eating that has allowed me to maintain a single digit body fat percentage year round, while still being able to make substantial strength and performance gains. But pleasing aesthetics are only a small part of the many benefits to be had from following a low carb lifestyle. Now I just got done writing a 15 page research paper on the federal reserve, so the last thing I want to do is list a bunch of sources again. So I'm leaving it up to you to verify my claims for yourself. But I am telling you, the studies are out there, I have thoroughly read many of them, and you can certainly find them if you try. But for me, the most important experiment ever undertaken was my own, which was conducted upon myself. I know what benefits a low carb lifestyle has brought to me and they simply can not be argued. However, here is the link to one study that proves the effectiveness of a low-carb diet over a low-fat diet http://www.annals.org/content/140/10/769.short Other benefits of a high fat, low carb lifestyle include: 1. Decreased serum triglyceride levels 2. Increase in good cholesterol, decrease in bad cholesterol 3. Increased levels of testosterone 4. Increased insulin sensitivity 5. Consistent energy levels throughout the day 6. The right to eat bacon, and probably the most important reason... 7. You don't have to worry about your toes falling off! So you see, fat is not the enemy. It never has been. Fat is not what makes you fat. Carbs are what make you fat. I'm sticking to a low carb lifestyle because I know it works, and it works damn well And I'm keeping my toes too damnit! Questions? Comments? Rebuttals? Post them in the comment section! Just keep it cool. Commentszach 03/17/2011 14:17

"Big" Pete is right, it is way to hard to follow a low carb diet at college, or any sort of a healthy diet for that matter. I put on 20lbs during my college years. Beer and pizza will do that to you

John--I hear you man, food prep here is all about the bottom dollar and unfortunately, like sex, carbs sell. Don't get me wrong, I eat omlettes and salads and shit here, but they are not always availible. I have no vehicle also, so trips to the store are a real rarity because it takes me almost an hour and a half to get there on public transport.

What is your take on Greek yogurt and oatmeal? Do you put those in your diet as well? Is the cheese you eat low fat?
Reply
Pat 03/18/2011 04:02
Hey Terry, you may be able to get away with plain greek yogurt on occasion if you are following a ketogenic diet; oatmeal however is probably not a good idea if you want to maintain a ketogenic state.

While I agree that a ketogenic diet is beneficial, I would just like to point out the flaw in your female standard. Women below 12% bodyfat tend to lose bone mass and suffer many lifelong ill effects. Granted, some women can go under 12% and be ok, but that is the exception.

Terry, I had a friend who lived in Florida for a while and he actually drank the raw milk for "pet purposes" and said he never had a problem with it. If that were my only option, I'd go for it, but I'll leave that one up to you though.

I stayed on a maximum of 30g carbs / day for about 3 months. Not sure if that was long enough to adapt. Things I noticed was that I was very worn out from my normal weekly training, and I also put on some lbs or five of new fat tissue.
Reply
Pat 03/22/2011 11:32
3 months is more than enough time to adapt especially if you were limiting carbs to less than 30% a day...that is unless you were refeeding every couple of days or so, then I can see how such problems would arise.

Nice posting Pat and i am a firm believer in this dietary approach. However, over the past few years I have become aware of the need to balance the alkalinity in our bodies. There are now numerous studies and publications which support the fact that an overly acidic environment in the body leads to amongst other things disease and at worst cancerous cells.

Pat Flynn 03/24/2011 14:19
Craig here is an excerpt from an article that my good friend and colleague Brian Petty RKC wrote a while back that clears up a lot of the confusion about the alkaline balance in our bodies when following a ketogenic diet.

I recently attempted a virtually no-carb diet for a couple of weeks. During that time I experienced dizziness, blurred vision and an overall lack of ability to focus. I workout with kettlebells/bodyweight 3-5 days a week and do brazilian jiu jitsu 2x/week. During the 2 weeks, I lost no weight. I was flat lined.
Reply
Pat 03/30/2011 09:17
Hey Mike, sounds to me like you just had a very rough adaptation period. The blurred vision, lack of focus, and dizziness is all related to glucose levels, specifically in your brain. Your brain run on on either glucose of ketones. SO you opted to cut out all your carbs at once, which in turn significantly dropped your blood glucose levels and called all those side effects. It is not until you have reached a state of ketosis and when your brain starts using ketones for fuel that you will feel better and start losing weight.

Great post Pat, thanks for sharing. I'm just starting out the Paleo diet, and this information has made it that much easier. I have a question if you don't mind answering it--After your body is in ketosis for a long time, how much would eating carbs mess with your ability to re-enter ketosis? Would I start from day one, and have to go through a couple low-energy days, or does the fact that I was previously in ketosis for a long stretch of time increase my ability to re-enter that state? I'm just wondering how one small cheat meal, or a social meal where I'd have/want to eat something with carbohydrates (pizza party or what-have-you), would effect the ketosis state of my body.

I feel like after reading this over again, and reading all the comments this time, then I am much like your friend Marcus... Even though we both agreed that I'm in my head a lot lately and psyching myself out. I know you say scales lie and mirrors don't but now I'm thinking that the mirrors are changing and that I just look disgusting. I'm gonna keep with this a little longer before I switch back to my older diet. I agree when Marcus said it was because of the calorie intake, on my old diet I NEVER went a calorie over 1200, now between almonds and chicken and all that jazz I'm sure that I am soaring way above that number. (I understand the view on a calorie is a calorie) I just think for my body it either is a. not working. b. Working and I'm just a psycho. hahah

John, for an athlete and/or somebody who is looking to maximize performance as a primary goal as opposed to weight loss, then yes, I would recommend either taking some waxy maize or vitargo post workout to replenish muscle glycogen. I will put a post up shortly about this, but for sheer weight/fat loss, no I would not recommend swallowing a bunch of carbs post workout

Maybe you could also describe what you mean by binge and purge, and how you apply it. If you lose your ketogenic state after having been in it, how long does it take to get back in it and do you feel bad while making the transition again?
