Ketoacidosis occurs mainly in people with type 1 diabetes if they do not take insulin. In diabetic ketoacidosis (DKA), blood sugar and ketones rise to dangerous levels, which disrupts the blood’s delicate acid-base balance. People in ketoacidosis feel extremely ill and experience profound dehydration, vomiting, abdominal pain, and weakness. DKA requires hospitalization so that IV fluids and insulin can be given to gradually and safely lower blood sugar.
The understanding of “What is a Keto Diet” has become blurred thanks to the proliferation of Keto Diet “experts”. Many of these “experts” recommend several variants of Keto Diet and lifestyles which they claim can be modified to any walk of life. However, in most instances what they are actually recommending are Low-Carb lifestyle programs. These are neither weight loss programs, nor Ketogenic. With that said, there’s nothing wrong with adopting a Low-Carb lifestyle, but if your goal is weight loss, then changing your eating lifestyle should come after you’ve achieved your weight loss goals.
Recently, many of my patients have been asking about a ketogenic diet. Is a ketogenic diet safe? Would you recommend it? Despite the recent hype, a ketogenic diet is not something new. In medicine, we have been using it for almost 100 years to treat drug-resistant epilepsy, especially in children. In the 1970s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss.
Luiza Petre, MD, a board-certified cardiologist and weight management specialist in New York City, suggests focusing on eating more low-carb, fiber-rich foods that can help beat this bowel issue. “Try fibrous vegetables, such as broccoli, asparagus, and cabbage, consume more fat like MCT oil, coconut oil, or ghee, and, as always, drink plenty of water,” she says.
“Your liver produces ketones all the time, but the rate depends on carbohydrate and protein intake,” says Jeff Volek, Ph.D., R.D., a professor of human sciences at Ohio State University. When the majority of your diet is made up of of carbs and protein, ketogenesis slows. Replacing carbs and protein with fat will put your body into ketosis, thus ramping up ketone production. This takes about three days to induce.
The research on how diet affects PCOS is minimal, but there is one compelling study on the ketogenic diet and women with PCOS. In this study, five overweight women ate a ketogenic diet (20 grams of carbohydrates or less per day) for 24 weeks. The results were astounding — average weight loss was 12%, free testosterone decreased by 22%, and fasting insulin levels dropped by 54%. What’s even more impressive is that two of the women became pregnant despite previous infertility problems.
