The UCSF team has discovered a molecular key to the diet's apparent effects, opening the door for new therapies that could reduce harmful brain inflammation following stroke and brain trauma by mimicking the beneficial effects of an extreme low-carb diet. Raymond Swanson, MD, a professor of neurology at UCSF, chief of the neurology service at the San Francisco Veterans Affairs Medical Center, and senior author of the new study. In the paper, published online Sept. 22 in the journal Nature Communications, Swanson and his colleagues found the previously undiscovered mechanism by which a low-carbohydrate diet reduces inflammation in the brain. Importantly, the team identified a pivotal protein that links the diet to inflammatory genes, which, if blocked, could mirror the anti-inflammatory effects of ketogenic diets. The high-fat, low-carbohydrate regimen of ketogenic diets changes the way the body uses energy. In response to the shortage of carb-derived sugars such as glucose, the body begins breaking down fat into ketones and ketoacids, which it can use as alternative fuels.
In rodents, ketogenic diets - and caloric restriction, in general - are known to reduce inflammation, improve outcomes after brain injury, and even extend lifespan. These benefits are less well-established in humans, however, in part because of the difficulty in maintaining a ketogenic state. In addition, despite evidence that ketogenic diets can modulate the inflammatory response in rodents, it has been difficult to tease out the precise molecular nuts and bolts by which these diets influence the immune system. In the new study, the researchers used a small molecule called 2-deoxyglucose, or 2DG, to block glucose metabolism and produce a ketogenic state in rats and controlled laboratory cell lines. The team found that 2DG could bring inflammation levels down to almost control levels. CtBP that acts to suppress activity of inflammatory genes. In a clever experiment, the researchers designed a drug-like peptide molecule that blocks the ability of CtBP to enter its inactive state - essentially forcing the protein to constantly block inflammatory gene activity and mimicking the effect of a ketogenic state. Peptides, which are small proteins, don't work well themselves as drugs because they are unstable, expensive, and people make antibodies against them. But other molecules that act the same way as the peptide could provide ketogenic benefits without requiring extreme dietary changes, Swanson said. The study has applications beyond brain-related inflammation. The presence of excess glucose in people with diabetes, for example, is associated with a pro-inflammatory state that often leads to atherosclerosis, the buildup of fatty plaques that can block key arteries. The new study could provide a way of interfering with the relationship between the extra glucose in patients with diabetes and this inflammatory response.
It is basically black coffee with a generous dollop of fat (could be ghee, high fat cream, olive oil). Many people on keto diet replace their breakfast with bullet coffee, and if you hear it from them firsthand, they will tell you how filling it is - moreover, it also keeps you charged and kickstart your day in the perfect manner. You can also have tea but milk is a restriction here - try black tea without sugar or try adding almond milk to your tea. It is said that to get the most from a ketogenic diet, it is important to also follow a workout routine. In fact many athletes, runners, cyclists follow a ketogenic diet when they are training. It is believed that following a ketogenic diet works on your muscle-to-fat ratio and increases the amount of oxygen present in your body. While there are many controversies surrounding the ketogenic diet, it is said to be safe for most people by keto experts.
The first category is of people who take medication for diabetes, for example, insulin. People taking medication for high blood pressure fall in the second category and the third category is of pregnant and breastfeeding women. Ketogenic diet is well known for its weight loss benefits but it is said to be an extremely beneficial diet for diabetes, pre diabetes, PCOS, heart ailments, alzheimer, acne and more. Many diabetics have benefited from the diet and have shown reduced blood sugar levels. This is primarily because the disease is linked to high blood sugar and impaired insulin in the body. A ketogenic diet helps a person lose weight, which is linked to Type 2 diabetes, metabolic syndrome and prediabetes too. A study proved that the diet helped in improving insulin sensitivity by 70 per cent. Many people advise against a ketogenic diet because we have always seen fat is the real evil and this diet makes you eat more of that. But there have been studies that showed improvement in HDL and blood pressure. Furthermore, the diet is also being tested on cancer patients and cancer survivors. Also, if you have had an issue with appetite control, then this diet will work wonders for you. Most people following keto diet have experienced dramatic hunger control - their appetite reduces considerably. So you eat less and lose more. Combination of Intermittent fasting with keto is also a great technique to lose weight faster. While the high-fat diet has several health benefits, there have been certain studies that state that in the long-term can have adverse health effects. Last but not least, it is important to consult your physician or a health specialist before you start the ketogenic diet. That is the reason it is always advised to start under guidance so you can avoid all health errors.
