Alright, sooo, let me figure out where to start here.
PROTEIN and KIDNEYS:
Basically the research they did in 2003 found that higher protein diets can accelerate kidney disease in those who are already at risk. It will not create it in those who are not at risk. High protein will create a greater amount of nitrates in the blood which simply mean drink more water. Basically if you are drinking enough water, there is not even a supposed negative side effects… Does that make sense?
Here’s a little more info –> “Dehydration forces the kidneys to work harder to clean toxins from the blood. Kidneys not only filter the blood, but they also help regulate blood pressure and the number of red blood cells. Increased protein intake leads to a build-up of nitrogen in the blood. The nitrogen ends up at the kidney in the form of urea, where it needs to be cleaned from the blood and got rid of in the urine. The resulting increase in urination can cause dehydration, which can lead to strain on the kidneys” – This is from the director of the American Kidney
Some more quotes on their findings –>The researchers found that in women who had normal kidney function, there was no link between high-protein diets and a decline in renal function. But those who already had a mild kidney problem who ate a high-protein diet, particularly one high in meat protein, showed some deterioration. Dairy or vegetable protein was not linked with worsening kidney function. AND also… “Elizabeth Ward, founder and president of the British Kidney Patient Association said: “If you have healthy kidneys, you can’t eat enough protein to damage your kidneys.”..
There is not a higher correlation of Kidney Failure associated with Ketosis… none… not even implied. Additionally one should note that a low carb diet is really not higher than the recommended dosage of protein so its really not even considered a high protein diet. Its just higher in protein than a non-low carb diet.
Ok, moving on…
INSULIN:
Just a couple things to day about this. First off, carbohydrates and sugars spike insulin levels which lead to sugar crashes, and more detrimental, insulin spikes. Insulin resistance is a growing epidemic. The constant insulin spikes caused by starchy carbohydrates and foods high on the Glycemic Index are leading to the pancreas not producing insulin at all… Researchers have been seeing this happening more and more as the low fat craze hit the media. Not to mention that several studies have shown that when you have insulin spikes, you have greater appetite which leads to overeating. There was a study conducted a few years back that took cute little rabbits and placed tubes directly into their stomachs. They gave half the rabbits sugar water basically (directly into their stomach) and the other half a saline solution… then they monitored the amount of food they ate over the next 24 hours. It showed that the rabbits with the sugar water actually ate a significantly greater amount of food than the rabbits that did not have the sugar. That was an earlier study, at the moment it is pretty common knowledge that insulin levels are directly proportional to appetite and food consumption.
KETOSIS (How it works):
Basically yes its is the switch from burning sugar for energy into burning fat for energy. Does it use your fat storage’s for energy? No that’s actually a false statement. It does burn fat, from foods and from your fat storage’s for energy. Is it unhealthy or dangerous? Not at all. Basically your body is made to work two ways… sugar or fat as energy. We are naturally hunters and gatherers… Sometimes we burn sugar, sometimes we burn fat. During the winter months when berries and fruits were rare, our bodies would use the fats used on meats to sustain us through winter. Our body does prefer sugar to fats, but it is not unhealthy or dangerous to use one vs the other. If anything sugar is much more dangerous than fats.
FATS and CHOLESTEROL:
Fat does not make you fat. Fat is not stored without carbs… what does that mean? Well its actually that fat is not stored without insulin and carbs spike insulin levels. You need carbs in order to store fats… here is something that tries to break it down the science of it (This is causing insulin resistance… as well as epidemics of child diabetes among many other health issues.)
“As alluded to earlier, without alpha-glycerol phosphate present, fatty acids cannot be bound into triglyceride (which is stored body fat). Therefore: (and this wraps it up)…You cannot gain fat on a ‘high fat/low carb’ diet.”
Article here —> High Fat Diet
Fat does not clog arteries or cause high cholesterol.
Here are a couple cholesterol links… this shows that hydrogenated oils are the biggest and worst culprit for clogged arteries… and if you’ve ever read a food label for crackers or bread or any refined carbohydrate you will know that they are packed full of trans fats (hydrogenated and partially hydrogenated oils). Coincidence that we blame fats when all the conglomerates are pumping out these refined carbs packed full of trans fats?
“Hydrogenated fats, also known as trans-fats, are three times more dangerous than saturated fats, because they increase the bad cholesterol and decrease the good cholesterol. Hydrogenated fats are hidden in many processed products such as cakes, biscuits, cookies, cereals, rolls, candies, breads and fast foods.”
Here’s a link Lower Bad Cholesterol
Additionally there is a growing number of research – this particular study was conducted by Duke University — that shows that low carb diets actually increase good cholesterol while lowering bad cholesterol… this is a report of the 2005 study . This was a 6 month study..
Cholesterol
Another study was released in July of 2008 that was conducted over a period of 2 years that shows staggering results
2 year study
What is commonly mistaken for fats is actually a combination of fat AND carbohydrates. That is clogged arteries is a result of eating things like french fries, Philly cheese steak, Cheeseburgers, steak and potatoes, pizza and any other number of foods that mix high carbohydrates (spiking insulin) with high fats… Fat cannot be stored in the body without binding to alpha-glycerol phosphate. When you don’t have carbs, your body literally poops out the fat that is not used for energy. It cannot be stored in your body, arteries, or otherwise. Here is an interesting article that I think is well worth the read… it is in addition to a growing number of evidence in this realm
Fat won’t make you fat There is also Lots of new studies like the one I linked above that show that ‘high fat / low carb’ diets actually increase good cholesterol while decreasing triglycerides and bad cholesterol.
Saturated Fats
Here is someones criticism of the studies against fat — all of which as a researcher become very important. Such as all the studies of fat in diet didn’t record the number of carbohydrates being consumed along side these fats. A huge error for those of the scientific community to ignore other diet variables. Bad Science
KETOACIDOSIS:
I’d like to also point out that Ketosis is commonly mistaken by nay Sayers as Ketoacidosis — “Ketoacidosis should not be confused with ketosis, which is one of the body’s normal processes for the metabolism of body fat. In ketoacidosis, the body fails to adequately regulate ketone production causing such a severe accumulation of keto acids that the pH of the blood is substantially decreased.” Many people refer to ketosis as a “dangerous metabolic state” but they are actually referring to Ketoacidosis which symptoms are pretty severe including vomiting, weakness and confusion. It is most common and dare I say ONLY occurring in Type 1 diabetics who cannot produce insulin, and in alcoholics who are experiencing severe dehydration among other consequences of high alcohol consumption and lack of nutrition.
Here is a wikipedia link http://en.wikipedia.org/wiki/Ketoacidosis
OTHER COMMON LOW CARB MYTHS:
Good Article with some myths though. As a very important side note – People have lots of misconceptions about low-carb diets. There are a lot of common MYTHS about low-carb eating all over the internet. The assumption is that you eat bacon and cheese and steak and that’s all… that’s completely untrue. In fact most research shows that low-carb “dieters” actually increase their vegetable intake… “A recent study suggests that the major change in eating patterns for dieters on low-carbohydrate diets has been the addition of large amounts of vegetables and salads to replace carbohydrates removed from their diet. The report was published in the open access journal Nutrition Journal.
I find this to be very true for myself… I eat WAY more veggies when I’m low carbing. My fiber intake is tripled and the carbs that I do get are complex carbs from veggies, not starchy simple carbs and sugars. The foods I eat the most are Zucchini, Spinach, Raspberries, avocados, cucumbers and tofu.
Here’s a link to this article… just one of many. http://www.naturalnews.com/021141.html
Here is a really good read on the 7 most common myths of low carb diets…
Low Carb Myths
I’m sure that you wouldn’t disagree that a diet highest in fiber and vegetable isn’t bad for you. You do eat fats as well but I don’t necessarily see how its higher than normal. I eat Avocados, a piece or two of cheese a day, and I do use cream for my coffee, and have salmon maybe once a week and maybe some cream cheese here and there to spice things up. I also eat a LOT of flax seed meal and nuts. I’m not sure that anyone looking at it from a realistic perspective can say that is an unhealthy diet.
Lastly there is an extremely long and comprehensive article published in the New York Times a few years back that is packed with some great stuff… You can find it here –> http://query.nytimes.com/gst/fullpage.html?res=9F04E2D61F3EF934A35754C0A9649C8B63&sec=health&spon=&pagewanted=7
Here is the low-carb food pyramid for those of you interested. Does this really look unhealthy?

Ok.. I’m done for now, that was a lot.
