Research into the effectiveness of low-carbohydrate, high fat (LCHF) diets for preventing weight gain and diabetes has produced conflicting results, with some suggestion that diet suitability is not generalizable, but specific to individuals. Overall, for prevention, there is no good evidence that LCHF diets offer a superior diet choice to a more conventional healthy diet, as recommended by many health authorities, in which carbohydrate typically accounts for more than 40% of calories consumed.

From baseline to week 16, the mean body weight decreased significantly from 131.4 ± 18.3 kg to 122.7 ± 18.9 kg, BMI decreased from 42.2 ± 5.8 kg/m2 to 39.4 ± 6.0 kg/m2, and waist circumference from 130.0 ± 10.5 cm to 123.3 ± 11.3 cm (Table (Table3).3). The percent change in body weight was -6.6%. The mean percent body fat decreased from 40.4 ± 5.8% to 37.0 ± 6.0%. Systolic and diastolic blood pressures did not change significantly over the 16 weeks. The mean heart rate decreased from 81.2 ± 12.9 beats per minute to 74.6 ± 14.0 beats per minute (p = 0.01).

Positive science on ketosis coupled with personal successes passed by word-of-mouth have driven more people to explore the ketogenic diet, says Volek. More recently, the keto diet hints at having a promising therapeutic role in cancer, Alzheimer’s, Parkinson’s and polycystic ovary syndrome (PCOS). Research is still early in many areas, but Volek suspects there will more definitive answers on the wider scope of the diet’s benefits within the next decade.
In general, people on ketogenic diets tend to consume a lot of foods high in monounsaturated and saturated fats such as olive oil, butter (often butter from grass-fed cows is recommended), avocado, and cheeses. The high oleic types of safflower and sunflower oils (but not the regular forms of these oils) are also good choices, as they are high in monounsaturated fats and low in polyunsaturated fats.
“I have an interest in diabetes and preventative medicine and have started recommending intermittent fasting in combination with a low-carb, high-fat diet to all of my patients both for treatment and reversal of diabetes and general good health and prevention. I recommend the Diet Doctor website to all of my patients so they can find the best information from knowledgeable experts regarding living a low-carb lifestyle, from educational videos to amazing recipes and everything in between.”
The failure of Big Pharma to develop an Alzheimer's drug has been well-documented in the corporate-sponsored "mainstream" media. As Alzheimer's diagnoses continue to increase, drug companies are scrambling to develop the next big drug to market to seniors. In modern times, the most successful drugs in sales, so far, have been cholesterol-lowering statin drugs, as one out of every five people over the age of 50 are now taking drugs to lower one's cholesterol, raking in billions of dollars for pharmaceutical companies. The sick irony to this is that lowering one's cholesterol artificially is directly linked to declining cognitive health and diseases such as Alzheimer's, since 25% of one's total cholesterol is located in the brain. The failed scientific hypothesis behind these drugs is that cholesterol is a cause of heart disease, and that diets high in saturated fats contribute to high cholesterol. However, the actual science shows almost the opposite, and when one looks at death rates, for example, lower cholesterol rates do not equate to longer life - in fact the converse is true: higher cholesterol levels lead to longer life spans. The pharmaceutical industry and the U.S. government cannot afford to reverse their warnings against saturated fats and cholesterol, however, as it would be the same as confessing that the entire statin drug industry has been a scam, and that statin drugs actually cause more harm than good. This is the main reason why the USDA must continue supporting a low-fat diet and condemning saturated fats, even though the science does not support their positions. It is no surprise, therefore, to learn that peer-reviewed scientific studies continue to show that the high-fat ketogenic diet supports cognitive health and can help prevent or reduce cognitive diseases such as Alzheimer's. Here are four new studies just published on the high-fat ketogenic diet related to cognitive health, and preventing Alzheimer's Disease.
Animal proteins (meat, fish, etc.) have very little, if any, carbs. You can consume them in moderate amounts as needed to control hunger. Overall, choose fattier cuts of meat rather than leaner ones. For example, chicken thighs and legs are preferable to chicken breasts because they contain much more fat. We’ve got quick keto diet chicken recipes to help.
Eat fats with all your meals. Fats are the cornerstone of the ketogenic diet, and will encourage your body to burn fatty ketones for fuel. Typically, calories from fat should comprise 80 – 90% of your meals. (However, you cannot eat unlimited fats on a ketogenic diet; the calories can still add up and cause weight gain.) Examples of fatty foods include:
The Bulletproof Diet (download the roadmap for free here) counters these side effects by keeping protein levels even lower. It is a cyclical ketogenic diet, which means you eat keto for 5-6 days a week and then do a weekly protein fast, which lowers inflammation and kickstarts fat-burning. This is much better for your body and spurs weight loss even more. The Bulletproof Diet also involves a carb re-feed day, where you eat slightly more carbs than usual. Since keto diets mimic starvation, you want to make sure your body knows that food isn’t scarce (this is especially important for women trying to conceive).
