What Is the Bredesen Diet?

Making mindful decisions about the foods you eat, and when you eat them, builds the foundation for overall health. Neurologist Dr. Dale Bredesen developed KetoFLEX 12/3 as guidelines for healthy eating practices to reduce inflammation and promote brain function, backed by research. Continue reading to learn what the Bredesen Diet is and how to implement it in your life.

Ketosis and the Bredesen Diet

When you think of the average American diet, cheeseburgers, french fries, and fried chicken probably come to mind. Although what people eat varies around the world, much of the typical diet consists of far too much red meat, high-fat dairy products, processed foods, refined carbohydrates, added sugars, salt, and calories. These foods can cause inflammation in the body, especially disruptive to brain health.

The good news: lifestyle changes today can prevent diseases tomorrow.

Thanks to new research, we can better understand how the body processes food and practice healthier eating habits based on science. In his book, The End of Alzheimer’s, neurologist Dr. Dale Bredesen explores the impact of different daily eating habits on health. Early results from a successful clinical trial found that reaching a state of ketosis provides optimal health results.

Ketosis happens when your body uses fat as its primary source of fuel. It’s a metabolic state created when you consume high-fat foods and low amounts of carbohydrates.

A daily ketogenic diet consists of:

  • Fat (70–80%)
  • Protein (10-20%)
  • Carbs (5-10%), about 40 grams per day or less

After observing thousands of patients, Dr. Bredesen developed KetoFLEX 12/3, a mildly ketogenic, plant-rich, highly nutritive diet mixed with intermittent 12-hour fasting (including 3 hours before bed).

Consuming a high amount of carbohydrates and saturated fats with low fiber intake can lead to inflammation and potential insulin resistance. Switching from carb-based metabolism to healthy-fat–based metabolism, achieved through KetoFLEX 12/3, results in the healthier metabolic state of ketosis.

Health benefits of the Breseden KetoFLEX 12/3 Diet include:

  • Reduced inflammation
  • Metabolic flexibility and less insulin resistance, critical for brain health
  • Healthy autophagy (the body’s way of cleaning out damaged cells)
  • Prevention of “leaky gut” caused by inflammation and typically brought on by the consumption of sugar, gluten, or dairy

What Should I Eat?

Like a car engine, your body needs fuel to run. Putting high octane fuel in your car will help it run smoother and get better gas mileage. Similarly, putting nutrient-dense foods into your body changes will help it function better. Follow these recommendations from the Bredesen Diet to fuel your body:

Avoid Added Sugars, Grains, and Processed Foods

A study found that processed foods with added ingredients, like baked goods, frozen dinners, breakfast cereals, or candy, can have negative health effects. Instead, KetoFLEX 12/3 recommends eating foods closest to their natural state, like fresh produce or meats from local farms.

Supplement Your Diet with Brain-healthy Nutrients

A 90-day clinical trial found that supplementing your diet with healthy nutrients such as ginkgo leaf extract, phosphatidylserine, and turmeric promotes brain function.

Aim for Low Glycemic Foods

Glycemic index classifies carbohydrates and measures their potential to raise blood sugar and how quickly they raise your blood sugar. Not all carbs are created equal: nutritionists recommend eating foods with a lower glycemic index, like leafy vegetables and whole grains, which cause a slower and lower rise in blood sugar. Avoid simple carbohydrates, like soda and dessert, with a high glycemic index.

Follow a Mediterranean Diet

The Ikaria Study examined one of the healthiest, longest-living communities in the world on an island in Greece. Their secret: lots of healthy fats, such as olive oil, avocados, nuts, and seeds, key staples of the Mediterranean and Bredesen diet.

Avoid Fruit Juices

Fruit juices tend to have high levels of concentrated sugar and calories. Choose whole fruit instead, which has more fiber and less sugar content.

Indulge Freely in Greens

In his book, The End of Alzheimer’s, Dr. Bredesen writes, “Go crazy in the produce aisle or preferably in your garden or local farmer’s market.” The Bredesen Diet recommends 6-9 cups of non-starchy vegetables and leafy greens per day, gradually increasing the amount.

Minimize Meat and Dairy Consumption

Certain animal products cause inflammation. Dr. Bredesen recommends prioritizing animal protein rich in docosahexaenoic acid (DHA), found in salmon, mussels, oysters, and snow crab. Foods with choline, like eggs, liver, and grass-fed beef, also support overall health, especially memory.

Avoid Cooking at High Heats

A study found that foods cooked at high temperatures tend to contain harmful advanced glycation end products (AGEs), which could increase the risk of cognitive disorders.

Introduce Prebiotics and Probiotics

The Bredesen Diet recommends gradually introducing prebiotic foods such as mushrooms, jicama, and leeks as well as prebiotic foods with live active cultures such as sauerkraut, kimchi, sour pickles, miso soup, and kombucha, to improve gut health.

Eat Fish

Fish provides a great source of omega-3s, which can help reduce inflammation. Just make sure to avoid fish that tend to have high mercury levels. Refer to the acronym SMASH (salmon, mackerel, anchovies, sardines, and herring) for the safest fish to eat.

Get Tested for Food Sensitivity

A test for sensitivities will reveal foods contributing to leaky gut or inflammation and ingredients you should eliminate from your diet.

Extra Tips for the Bredesen Diet

Follow these tips to help the transition into a Bredesen Diet and begin the changes toward a healthy lifestyle:

Take MCT oil when initially making the transition into ketosis. This supplement helps combat some of the energy dips you may feel when initially changing your diet.

Invest in a ketone meter to track ketone levels in the blood. The Bredesen Protocol recommends levels of beta hydroxybutyrate from 0.5 mmol/L to 4 mmol/L, which indicates a state of mild ketosis.

Combine the Bredesen Diet with lifestyle changes like physical activity, stress management, and supplementation for best results (for personalized recommendations, check out Apollo Health’s ReCODE app).

Make small changes, one at a time. Commit to incremental changes that you’ll actually stick to, like cooking healthy recipes weekly or reducing sugary foods.

Start early—prevention is best. Research has shown that a healthy lifestyle early in life can have long-term benefits to protect cognition.

Making major lifestyle changes might feel overwhelming at first. But, these adjustments to follow the recommendations researched by Dr. Bredesen have tremendous benefits to promote brain function and overall well-being. Take charge of your health.
