Although the exact role of the keto diet in mental and brain disorders is unclear, there has been proof of its efficacy in patients with schizophrenia. And, to boot, it works to reverse many conditions that develop as a side effect of conventional medications for brain disorders, like weight gain, type 2 diabetes and cardiovascular risks. More research is needed to understand the role of the ketogenic diet in treating or improving schizophrenia, as the current available studies are either animal studies or case studies, but the benefits of a low carbohydrate, high-fat diet in neurology is promising.
An interesting effect on sexual function was induced by the nutritional intervention (Table S1; Figure 4). The EMAS-SF questionnaire reported no statistically significant changes for sexual activity in men (Figure 4A). However, the FSFI questionnaire for sexual activity in women evidenced that excitation (p = 0.043) and lubrication (p = 0.013) improved with statistical significance throughout the study. Moreover, from baseline to maximum ketosis, a statistically significant increase was observed in the score for the orgasmic domain (Figure 4B; 0.95; p = 0.034). Based on the FSFI mean total score, women included in this study showed sexual dysfunction (total score = 9.55) at baseline. This total score was improved at maximum of ketosis (total score = 10.48) and at the end of the nutritional intervention (total score = 9.8).
The insulin theory of obesity, in short, declares that the primary cause of obesity is higher carbohydrate diets because these diets increase insulin secretion more than any other diet. When insulin levels are high, fat storage will increase significantly and “starve” muscles and organs of energy. This causes increased hunger and overeating that results in obesity.
Drink lots of water. This is especially crucial on a low carb or keto diet. Why? When you eat carbohydrates, your body stores the extra as glycogen in the liver, where they are bound to water molecules. Eating low carb depletes this glycogen, which allows you to burn fat – but it also means you are storing less water, making it easier to get dehydrated. Instead of the traditional recommendation of 8 cups of water per day, aim for 16 cups when following a low carb lifestyle.
Regarding higher-carbohydrate diets, 20 studies reported higher energy expenditure, and this increase in energy expenditure was statistically significant in 14 of those studies. Overall, the evidence suggests that the carbohydrate and fat content of the diet has little impact on energy expenditure. In other words, low-carb diets do not have a significant metabolic advantage like many insulin theory proponents believe.
On the ketogenic diet, with carbs low, our bodies need to use glycerol from fatty acids in order to produce glucose (but under normal circumstances it doesn't use the fatty acids themselves). Producing glucose from glycerol is fairly inefficient, meaning our bodies have to break down a lot of fat to get a little glucose. Anytime our bodies do something inefficient it uses more calories than doing it the efficient way.
A ketogenic diet also has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term. There is even more controversy when we consider the effect on cholesterol levels. A few studies show some patients have increase in cholesterol levels in the beginning, only to see cholesterol fall a few months later. However, there is no long-term research analyzing its effects over time on diabetes and high cholesterol.
Low-calorie diets leading to rapid weight loss can cause headaches -- especially if your carbohydrate intake is too low. A study published in 2011 in the "Nutrition Journal" reports that symptoms of ketosis, which occurs when there is a buildup of metabolic byproducts called ketones in the body after breaking down fat instead of carbs as fuel -- include headaches, bad breath, weakness and constipation. To reduce your chance of getting a headache during weight loss, eat at least 130 grams of carbohydrates -- which is the recommended dietary allowance, or RDA -- daily and avoid losing more than 2 pounds per week.
“As a full-spectrum family physician since 2004, luckily I stumbled on the wonderful low-carb community two years ago after my amazing wife was forced to make dietary changes after surgery. I’ve never looked back! After transforming my own health, with help from resources like Diet Doctor, Jimmy Moore, and Dr. Jason Fung, I’ve committed to bettering the lives of my patients with intensive dietary management through LCHF and intermittent fasting. Empowering patients to make these lifestyle changes has truly brought back the joy of medicine for me. I am so thankful to all who have inspired me along the way.”
The keto diet (also known as ketogenic diet, low carb diet and LCHF diet) is a low carbohydrate, high fat diet. Maintaining this diet is a great tool for weight loss. More importantly though, according to an increasing number of studies, it helps reduce risk factors for diabetes, heart diseases, stroke, Alzheimer’s, epilepsy, and more1-6.On the keto diet, your body enters a metabolic state called ketosis. While in ketosis your body is using ketone bodies for energy instead of glucose. Ketone bodies are derived from fat and are a much more stable, steady source of energy than glucose, which is derived from carbohydrates.
The National Academy of Medicine recommends a minimum intake of 130 g of carbohydrate per day. The FAO and WHO similarly recommend that the majority of dietary energy come from carbohydrates. Low-carbohydrate diets are not an option recommended in the 2015-2020 edition of Dietary Guidelines for Americans, which instead recommends a low fat diet.
Keep an eye on your intake for nut or seed based foods, as they can be quite high in inflammatory omega 6’s. These include items like almonds, walnuts, pine nuts, sunflower oil and corn oil. Eating fatty fish and animal meat, keeping snacking to a minimum, and not over-indulging in dessert items that are dense in almond flour is usually enough to keep your omega’s at normal ranges.

There are numerous benefits that come with being on keto: from weight loss and increased energy levels to therapeutic medical applications. Most anyone can safely benefit from eating a low-carb, high-fat diet. Below, you’ll find a short list of the benefits you can receive from a ketogenic diet. For a more comprehensive list, you can also read our in-depth article here >
We’re going full on fats with breakfast, just like we did last week. This time we’ll double the amount of ketoproof coffee (or tea) we drink, meaning we double the amount of coconut oil, butter, and heavy cream. It should come to quite a lot of calories, and should definitely keep us full all the way to dinner. Remember to continue drinking water like a fiend to make sure you’re staying hydrated.
