It also may help stave off chronic diseases, like heart disease and type 2 diabetes, as well as act protectively against certain cancers. (34) The diet is also a boon to mental health, as it’s associated with reduced odds of depression. (34) There’s even some data to suggest it can be supportive in relieving symptoms of arthritis, according to a paper published in April 2018 in the journal Frontiers in Psychology. (35)
Pros: Technically a subtype of low-carb diet, the keto diet is unique: By depriving your body of carbohydrates, you not only force your body to become fat-adapted, but also, if you keep protein low as well, elevate your levels of ketone bodies, which is basically a sign your body is running on fat. The keto diet puts you in a unique metabolic state called ketosis wherein your brain burns ketones instead of glucose—and, in doing so, supposedly leads to clearer thinking. Physically, eating such a high amount of fat significantly increases your body’s ability to burn body fat, according to the study analysis. Research also shows keto athletes have a higher VO2 max, and are able to lose fat without losing strength or power.
Normal dietary fat contains mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate, leading to more food choices and larger portion sizes. The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil. Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant. The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.
Anna Taylor, RD, CDE, a licensed dietitian at the Cleveland Clinic in Ohio, says very-low-carb diets can hurt people with type 2 diabetes if done incorrectly. She and Keratsky say it’s important that anyone with diabetes who wants to try a low-carb or ultra-low-carb diet meet with a dietitian or physician to create a plan and make sure their eating style won’t react negatively with their current medicines.
The study, which was conducted by ETH Zurich in conjunction with University Children's Hospital Zurich, involved feeding mice two different types of diet (a ketogenic diet and a high fat diet, which causes the liver to become resistant to insulin) and then performing standard metabolic tests on them. Using specialized procedures the researchers were able to determine the effects of internal sugar production from the animal (mostly the liver), and sugar uptake into tissues (mostly the muscle), during insulin action.
Benefits The main ingredient in hummus, chickpeas pack an impressive amount of fiber (more than half of a woman’s 25 g daily quota), as well as iron, zinc, folate, and magnesium, according to a paper published in November 2014 in the journal Applied Physiology, Nutrition, and Metabolism. (15,16) The stats above are for a whole cup, but you only need ½ cup per day to reap the benefits.
Obviously, if you could keep the weight off, it may help in preventing diabetes. There are many risk factors for diabetes, but the Diabetes Prevention Program in 2002 followed 1,079 people with prediabetes. This groundbreaking study showed that 58% were able to prevent the progression of developing diabetes through diet and exercise. Want to know what the great news is? They didn’t have to eat 20 carbohydrates per day to achieve this!
“We do not recommend the diet,” he says. “It works for weight loss, and the liver insulin resistance we observe might be transient. But the diet is simply not necessary and probably not the best choice for weight loss,” he says. “Ketogenic diets are often very low in fiber, which may have bad effects on gut health and overall health, especially over a long term. Diets high in fiber and low in fat work equally well or better than low-carb plans, in many studies, to achieve weight loss and lower glucose intolerance.”
The primary outcome was the change from baseline to week 16 in hemoglobin A1c. Changes in all variables were analyzed by the paired t-test or Wilcoxon signed-ranks test, as appropriate. Linear regression analysis was used to examine predictors of change in hemoglobin A1c. A p value of 0.05 or less was considered statistically significant. Statistical analysis was performed using SAS version 8.02 (SAS Institute, Cary, NC).
Cyrus Khambatta earned a PhD in Nutritional Biochemistry from UC Berkeley after being diagnosed with type 1 diabetes in his senior year of college at Stanford University in 2002. He is an internationally recognized nutrition and fitness coach for people living with type 1, type 1.5, prediabetes and type 2 diabetes, and has helped hundreds of people around the world achieve exceptional insulin sensitivity by adopting low-fat, plant-based whole foods nutrition.
This article is a perfect example of the misinformation regarding diabetes and insulin resistance. The authors stance against the ketogenic diet is a simple, “its just too hard, I cant live without fruit.” She projects her lack of willpower to her audience. Ketogenic diets are a great way to reduce insulin levels and get to the root of the problem.
The diet suggests a specific number of servings of the recommended foods listed above. The sample plans provided by the National Heart Lung and Blood Institute (NHLBI) are based on 1600, 2000, or 2600 calories daily. For 2000 calories a day, this translates to about 6-8 servings of grains or grain products (whole grains recommended), 4-5 servings vegetables, 4-5 fruits, 2-3 low fat dairy foods, 2 or fewer 3-ounce servings of meat, poultry, or fish, 2-3 servings of fats and oils, and 4-5 servings of nuts, seeds, or dry beans per week. It advises limiting sweets and added sugars to 5 servings or less per week. The plan defines the serving sizes of each these food groups.
The ketogenic diet is a medical nutrition therapy that involves participants from various disciplines. Team members include a registered paediatric dietitian who coordinates the diet programme; a paediatric neurologist who is experienced in offering the ketogenic diet; and a registered nurse who is familiar with childhood epilepsy. Additional help may come from a medical social worker who works with the family and a pharmacist who can advise on the carbohydrate content of medicines. Lastly, the parents and other caregivers must be educated in many aspects of the diet for it to be safely implemented.
One downside to a ketogenic diet for weight loss is the difficulty maintaining it. “Studies show that weight loss results from being on a low-carb diet for more than 12 months tend to be the same as being on a normal, healthy diet,” says Mattinson. While you may be eating more satiating fats (like peanut butter, regular butter, or avocado), you’re also way more limited in what’s allowed on the diet, which can make everyday situations, like eating dinner with family or going out with friends, far more difficult. Because people often find it tough to sustain, it’s easy to rely on it as a short-term diet rather than a long-term lifestyle.
