I was led to believe that large amounts if ketosis can have adverse health effects.

I just saw an Optimax slimming capsule commercial in which the model said, “that’s because I’m in ketosis: my body is burning excess fat …” etc

Are there dangers in such programs?

Controversy

Some clinicians regard eliminating carbohydrates as unhealthy and dangerous. However, it is not necessary to eliminate carbohydrates from the diet in order to achieve a state of ketosis. Other clinicians regard ketosis as a safe biochemical process that occurs during the fat-burning state. Ketogenesis can occur solely from the byproduct of fat degradation: acetyl-CoA. Ketosis, which is accompanied by gluconeogenesis (the creation of glucose de novo from pyruvate), is the specific state with which some clinicians are concerned. However, it is unlikely for a normal functioning person to reach life-threatening levels of ketosis, defined as serum beta-hydroxybutyrate (B-OHB) levels above 15 millimolar (mM) compared to ketogenic diets among non diabetics which “rarely run serum B-OHB levels above 3 mM.” This is avoided with proper basal secretion of pancreatic insulin. People who are unable to secrete basal insulin, such as type 1 diabetics and long-term type II diabetics, are liable to enter an unsafe level of ketosis, eventually resulting in a coma that requires emergency medical treatment.

The anti-ketosis conclusions have been challenged by a number of doctors and advocates of low-carbohydrate diets, who dispute assertions that the body has a preference for glucose and that there are dangers associated with ketosis. The Inuit are often cited an example of a culture that has lived for hundreds of years on a low-carbohydrate diet. However, in multiple studies the traditional Inuit diet has not been shown to be a ketogenic diet. Not only have multiple researchers been unable to detect any evidence of ketosis resulting from the traditional Inuit diet, but the ratios of fatty-acid to glucose were observed to be well below the generally accepted level of ketogenesis. Furthermore, studies investigating the fat yields from fully dressed wild ungulates, and the dietary habits of the cultures who rely on them, suggest that they are too lean to support a ketogenic diet. With limited access to fat and carbohydrates, cultures such as the Nunamiut Eskimos—who relied heavily on caribou for subsistence—annually traded for fat and seaweed with coastal-dwelling Taremiut.

The Inuit consumed as much as 15-20% of their calories from carbohydrates, largely from the glycogen found in raw meats. Furthermore, the blubber, organs, muscle and skin of the diving marine mammals that the Inuit ate have significant glycogen stores that are able to delay postmortem degradation, particularly in cold weather.

Whether a no-carbohydrate diet would be safe for non-Inuit is also disputed: Nick Lane speculates that the Inuit may have a genetic predisposition allowing them to eat a ketogenic diet and remain healthy. According to this view, such an evolutionary adaptation would have been caused by environmental stresses. This speculation is unsupported, however, in light of the many arctic explorers, including John Rae, Fridtjof Nansen, and Frederick Schwatka, who adapted to Inuit diets with no adverse effects.

Schwatka specifically commented that after a 2- to 3-week period of adaptation to the Inuit diet he could manage “prolonged sledge journeys,” including the longest sledge journey on record, relying solely on the Inuit diet without difficulty. Furthermore, in a comprehensive review of the anthropological and nutritional evidence collected on 229 hunter-gatherer societies it was found that, “Most (73%) of the worldwide hunter-gatherer societies derived >50% (=56–65% of energy) of their subsistence from animal foods, whereas only 14% of these societies derived >50% (=56–65% of energy) of their subsistence from gathered plant foods,” suggesting that the ability to thrive on low carbohydrate diets is widespread and not limited to any particular genetic predisposition. While it is believed that carbohydrate intake after exercise is the most effective way of replacing depleted glycogen stores, studies have shown that, after a period of 2–4 weeks of adaptation, physical endurance (as opposed to physical intensity) is unaffected by ketosis, as long as the diet contains high amounts of fat. Some clinicians refer to this period of keto-adaptation as the “Schwatka Imperative” after the explorer who first identified the transition period from glucose-adaptation to keto-adaptation.

Yeah a lot of wordy stuff that means you’d be mad to try it without researching your own genetic trail first.

Super-careful slimming people rarely use ketosis,
Even though the sound of it is something quite atrocious,
If you use it long enough, it can cause thrombosis,
Super-careful slimming people rarely use ketosis.

Nice

What about Hairytosis?
