RE: Twistedlinks critique under the theory of the keto diet

Pros in blue, cons in black, both in green stress test:source 1 http://www.bodybuilding.com/fun/keto.htm 1.
The main benefit being that it increases the body's ability to utilize fats for fuel, which gets very lazy on a high carbohydrate diet. When on high carbohydrate diets the body can usually expect an energy source to keep entering the body. But in the state of ketosis the body has to become efficient at mobilizing fats as energy.
Really? High carbohydrates make your body stop burning fats? So, theyre saying, on a standard carbohydrate/protein/fat split of 50/25/25 all them 50% carbs (1500 calories worth) is going to be burnt, while fats wont? Fact:when the body has heightened its blood sugar levels to normal standards under homeostasis, it will convert all left over carbohydrates to glycogen, once all areas are full, it will convert this carbohydrate to fat, and isnt that good according to this diet? that your macronutrients are more-so fats? Also note
When on high carbohydrate diets the body can usually expect an energy source to keep entering the body.
So when eating 75% Fats in 5-7 meals throughout the day isnt making a constant energy source entering the body? surely if the body was hormonally responding to 5-7 fat filled meals, it would actually inhibit fat burning around the muscles unless absolutely needed, and still rely on dietary macronutrients? Fact:Most tissues prefer fats as energy than glucose, this includes muscles as a whole, and cardiac muscle (hence why cardio is good at burning fat) The only things that prefer glucose is the nervous system workings, and red blood cells. So when your body stores the carbohydrates-it will do this anyway, of course, if the body lacks glucose, the body does become more efficient at burning fats-that is true.
Another nifty thing about being in a state of ketosis is that if the body has no further use for ketones they can simply be excreted through urine as a waste product. This means that at times your body will be peeing out body fat! This is a novel theme because you body is very efficient at storing energy substrates for later use.
Peeing out bodyfat? where is the science behind actual whole fatty acid chains being broken down i the body and then entering the kidneys via water and urea to then be removed as a waste product? Doesnt sound good to me Little bit of knowledge-when a glucose ring is "unwound" into a chain structure-it is a ketone, just a little knowledge there.
Ketosis has a protein sparing effect, assuming that you are consuming adequate quantities of protein and calories in the first place. Once in ketosis the body actually prefers ketones to glucose. Since the body has copious quanities of fat this means that there is no need to oxidize protein to generate glucose through gluconeogenesis
. Fact:Gluconeogenesis will ONLY occur if glucagon is present in moderate amounts, glucagon is the hormone that will breakdown glycogen to glucose, Gluconeogenesis will ONLY occur if GLYCOGEN reserves are almost COMPLETELY used up, in other words, the liver will convert amino acids into glucose for energy. This will only occur under low levels of glycogen (glucose storage unit) what can we deduce from this? that gluconeogenesis ISNT a problem to ANYONE as long as they have carbohydrates with there meals, proteins will be used for building muscle vastly better with carbohydrates as a part of every meal (which may i say is what danmirage has been saying all along) The funny thing, is gluconeogenesis occurs with LOW glucose levels right? well your carbs are 5% so actually, ketogenic dieters are actually converting most of there protein INTO glucose, which is a complete waste.
Another benefit has to do with the low levels of insulin in the body, which causes greater lipolysis and free glycerol release compared to a normal diet when insulin is around 80-120. Insulin has a lipolysis blocking effect, which can inhibit the use of fatty acids as energy. Also when insulin is brought to low levels many beneficial hormones are released in the body such as growth hormone and other powerful growth factors.
This is just obviously dangerous, lowering insulin? come on guys, thats the problem diabetics have, not enough insulin, so when it comes to "carb up" time for all keto dieters, youre going to maybe have some side effects of diabetes folk, very high sugar blood levels, because your body is now become less efficient at producing insulin this is without a doubt one of the most worrying aspects of this diet.
Another small but very important benefit about the ketogenic diet is that when in the state of ketosis, ketones seem to blunt hunger in many people. I mean honestly, what is not better than being on a low calorie diet and not being hungry all the time like you usually are such as on a high carbohydrate diet. Since on the ketogenic diet you have to consume a lot of fat, which hold 9 calories, you are not getting much food volume. This makes not being hungry a very good thing when on the diet. When you add such thermogenics like the ECA stack and prescription appetite suppressants you won't even think about your next meal. It's kind of funny that when the Atkins' diet first came out one of the early criticisms was that the diet blunted hunger too much! What, is it mandatory to be hungry on a reduced calorie diet?
Eating loads of sweets will still keep you hungry, it is no benefit, other than eating even more fats, the body has hormonal responses to what youre putting in your body, this hunger is possibly from lack of glucose and glycogen Overall, what can you determine from this diet? 1.It will work 2.They only half ass the science behind it 3.It will **** your body up-big time. I wont deny it doesnt work-it does, and the blue and green part posted is the reason it works, including the fact that the high lipid amounts increase testosterone levels through the roof, helping use whatever protein left into building muscle better than non ketogenic dieters. This diet puts severe stress on the liver, AND the nervous system which prefers glucose, and it is your nervous system that gives you your strength and your immune system in many respects.
