Really? Search engine much? ;) You just searched for "Fat" and "glycerol" and "glucose" and "to" and brought up 500,000 random result which do not match your query. If do it correctly and put the phrase in " " - you see only 2 result. Fat is not converted to glucose and burned as glucose for energy. Glycerol is not glucose. They are both forms of sugar but glycerol only exists for a brief part of the WHOLE process and the final result is not glucose. This is one argument against ketogenic diets - that your brain run on glucose and fat oxidation does not create glucose which is the prefered food for your brain. This is why when you starting ketogenic diets, it takes usually 2 weeks to adjust and you get foggy and cant think well... becuase you brain adapts to new fuel type (ketones) |

glucose is the ONLY food for the brain- period. if what you are saying is correct + your mad se skills, then you should be able to provide a link refuting the science of what is graphically explained in this picture http://oi54.tinypic.com/209n9lx.jpg |
i'm going to let you slide on your comment stating ketones are energy for the brain.
(ketones are by-products of converting stored fat for energy) |

Best book on the subject is The Ketogenic Diet by Lyle McDonald for explaining the real science of it, backed by peer reviewed medical studies... not just random and wrong opinions of "bros". Even if you go to big bodybuilding forums, you get as much shitty and wrong info as you would get if you asked how to rank number 1 in google for "porn" on this forum. 1,000,000 people has opinions but only 10 people are doing it... of those 10, only 3 did it on purpose ;) |
listen, all i know is that if i eat 100g of fat today, my body cant take it to make glucose to feed my brain.. simple and short.... and your brain can use ketones in addition to glucose

a quick search does reveal that the brain can get energy from ketones, good to know!
The brain gets its energy from ketone bodies when glucose is less available (e.g., when fasting). In the event of low blood glucose, most other tissues have additional energy sources besides ketone bodies (such as fatty acids), but the brain does not. After the diet has been changed to lower blood glucose for 3 days, the brain gets 30% of its energy from ketone bodies.[4] After about 40 days, this goes up to 70% (during the initial stages the brain does not burn ketones, since they are an important substrate for lipid synthesis in the brain). In time the brain reduces its glucose requirements from 120g to 40g per day.[5] |

hence why you dont die if u stop eating carbs.. if all u ate from today was 100% fat, u would still survive and ur brain wont just shut off |

Again, you wrong about glucose. It is only a myth/misunderstanding that your brain only runs on glucose. One that is argued non-stop anytime someone attacks the idea of ketogenic diets as being harmful using the wrong logic that your brain can only run on glucose. There is only some parts of your brain that needs fuel from glucose and that is made in this case of ketogenic diets from amino acids. So, with that, I leave you with a quote from wikipedia: On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing part of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this for fatty acids. Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and fatty acids do not cross the blood?brain barrier. Fortunately, the liver can use fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and substitute for glucose |
keto is not very healthy, try something like p90x

before and after pics?

should we hug it out?
lololololololol!!! |
100g of carbs

i didn't read the entire thread, but you should be eating more then 12 carbs a day on keto.... just make sure they are from fiber.

Congrats on yours as well and yeah if keto didn't work for you to stick with, everyone si different. I'm finding this kind of diet extremely easy to eat, even eating out often. Quote:
I have read through the link you posted, it does slightly go against other stuff I have read, but I'm not qualified to really say who's right or wrong in that whole debate (and the one here between you and dyna mo / the demon) - so for the moment at least, I will stick with what's working for me. Aside from the first few days, I actually have a lot more energy, sharper brain and am even waking up much earlier than I used to (I used to hate mornings). So it would appear at least my brain is getting the glucose it needs at this time. Quote:

Or, look at vikings and/or eskimos. When you are at sea the majority of your time, or living in frozen lands, agriculture isn't really something on your mind. Quote:

How many calories a day do you keto guys get?
I struggle getting the supposed daily caloric limit on non-processed. |
congrats man :thumbsup
ive done this diet a few times and pretty difficult to do when you are traveling frequently... people always look at you weird when you order 8 sides of bacon and a water |
Interesting topic :)

If you are eating low-fat as you mentioned, yeah I would think it's hard for all-natural foods to add up - I'd suggest adding stuff like natural peanut butter or olive oil in moderation to boost your cals maybe ? |

Thus far they have all been pretty accommodating though. |

How come that bodybuilders who are cutting, and eat LOADS of carbs still get to the 8-9% BF? Most people who want to lose weight and retain muscle go for the 50/35/15.
(50% carbs, 35% protein, 15% fat) So that's exactly the opposite, loads of carbs, loads of protein, a little bit of fat. Also, how can you do a decent workout on that amount of carbs? Not dissing at all, but if I don't eat a decent carb rich meal + a banana, I surely can't deadlift or squat! |
