I did the protein diet back in the 70's, Dr. Atkins. My husband and I had gone hiking the Uintas. Long story short. Got sick. Ended up in the hospital. Tests showed Giardia. Yes my not so smart hubby at the time said it was ok to drink some water trickling down a rock. I can see that big rock now.Dear Doctors: I mentioned to a friend that I’m starting a low-carb diet that puts your body into ketosis. She said not to because ketosis is one of the dangerous complications that can happen to people with diabetes. Is that right? If so, how can low-carb diets ever be safe?
Dear Reader: Your friend made a fairly common mistake. She has confused ketosis, which is a shift in how the body uses energy when carbohydrates are not available, with ketoacidosis, which is a serious complication of Type 1 diabetes.
The names are similar because both involve chemicals known as ketones. These are an alternative fuel source that the liver makes from stored fat. This occurs when glucose, which is derived from carbohydrates and is the body’s go-to source of energy, is in short supply. However, ketosis and ketoacidosis are not the same thing. Unlike ketosis, which is generally safe, ketoacidosis is a grave and life-threatening condition. Also known as diabetic ketoacidosis, it occurs in people living with Type 1 diabetes when their insulin levels become too low. This results in a buildup of ketones in the bloodstream, which causes the blood to become dangerously acidic. The condition is usually triggered by hormone imbalances that result from certain types of illness, or by a problem with insulin therapy.
Diabetic ketoacidosis is a medical emergency. Without immediate care, it can lead to death. Although it is seen most often in people living with Type 1 diabetes, under certain conditions, it is possible for it to occur in someone with Type 2 diabetes as well.
For those who don’t have diabetes, are in good health and are not pregnant, ketosis can be a safe and effective way to help with weight loss. It’s a metabolic state that is achieved by strictly limiting the amount of carbohydrates in the diet. Without carbohydrates to process into glucose for fuel, the body switches to burning stored fat for energy instead. It takes three to four days of eating 50 grams or fewer of carbohydrates to nudge the body into ketosis.

Well, the tests showed that I was in ketosis too. I explained to the Dr. that I was doing the high protein diet..Atkins. He started telling me how dangerous it was. Then he went and got copies of papers that showed how dangerous Dr. Atkins diet was.
I wasn't too worried because it was explained in Atkins book.
