Be careful if you hear that some fitness trainers advise you to go on a ketonic diet. Under Australian law they are not allowed to offer such information when not qualified. These diets were popular in the 1970s and 80s sometimes known as the Aitkens, Zone, or low Carb diets and have appeared under other names over recent times. They were made popular by trying and sadly, believing they are the way to quick weight(fat) loss. These are very dangerous and are often peddled by those with no qualifications in the area what-so-ever. Always consult with a professional dietician or qualified (university) nutritionist before embarking on these crazy regimes. There are many articles on the internet claiming research proves these diets work. Sadly they are never back by any real science backed evidence even though they will claim they are.

A report published by researchers at the Cincinnati Children’s Hospital Medical Center in the Journal of Neurology in 2000 described life-threatening cardiac complications in some children on a ketogenic, diet. A 5-year-old child, who developed cardiomyopathy, or heart weakening, prompted cardiac studies of all children under similar treatment in the clinic. Fifteen percent were found to have physical and electrical heart abnormalities. Excessive diuresis, or water elimination, and increased cholesterol related to high dietary fat intake were associated with the heart abnormalities. Adjustment of dietary fats and nutrients resolved most problems.
Compensate for the nutritionally unbalanced nature of a low-carbohydrate, ketogenic diet by taking nutrients you miss when you limit your consumption of grains, flours and fruits. Dr. H.C. Kang of Inje University College of Medicine in Seoul, Korea, reporting in a 2005 issue of the journal Epilepsia, documented that malnutrition combined with the diuretic nature of the diet can lead to electrolyte imbalances, liver damage and pancreatitis in the short term. Osteopenia, kidney stones and cardiac problems can develop after long-term dieting.
You might experience unpleasant sensations and discomfort on a ketogenic diet, according to Epilepsy.com. Dizziness, nausea, vomiting and diarrhea, also noted by Kang’s patients, are not uncommon. The high fat content and diuretic nature of the diet can cause some of these symptoms. In addition, poor regulation of dietary fat, which replaces some carbohydrates, can actually lead to weight gain on the diet, along with a danger of cardiac problems from increased cholesterol.
