EPISODE 39 - Cognitive Decline, Alzheimer’s Disease & Potential Benefits of Low-Carb & Ketogenic Diets w/ Amy Berger

In this episode, Dr. Bubbs interviews nutrition expert and author of the Alzheimer’s Antidote, Amy Berger MS, who takes a deep dive into topics of brain health, cognitive decline and Alzheimer’s disease. Amy discusses how Alzheimer’s disease is an energy crisis in the brain, how the brain cells are effectively “starving” for fuel and the potential role low-carb and ketogenic diets may play in providing the brain with an alternate and effective fuel source. She also unpacks the physiology of beta-amyloid plaques, neurofibrillary tangles, and the critical role of cholesterol and key nutrients like choline and vitamin B12 in brain health. Lots of actionable and insightful tips here from Amy!

"Lay-Ups" In This Episode

1)          In Alzheimer’s disease is an energy crisis in the brain

2)          Brain cells, called neurons, are struggling to metabolize glucose effectively and “starving” for fuel.

3)          Alzheimer’s disease has been dubbed “type-3 diabetes” in the medical literature.

"Performance Hacks" From This Episode

1)          The predominant abnormality in Alzheimer’s disease (AD)is a reduction in the rate of glucose uptake by the brain (i.e. CMRglu) and AD patients have shown up to 45% reductions in CMRglu.

2)          Beta-amyloid plaques are present in higher amounts in AD patients, formed for a protective reason, however when produced in excess (often due to chronically high insulin levels) contribute to cognitive decline.

3)          The brain contains 25% of the body’s total cholesterol amount and higher cholesterol levels are associated with less likelihood of cognitive decline in old age.

EPISODE 10 - Paleo Nutrition, the Salt Debate, Calcium Balance & Longevity w/ Dr. Loren Cordain

In this episode, Dr. Bubbs has the honour of interviewing one of the world's most renowned scientists, NY Times best-selling author, and the founder of the Paleo Diet movement Dr. Loren Cordain PhD. He discusses how he first got introduced to Paleo nutrition by Dr. Boyd Eaton, what hunter-gatherer ancestors "didn't eat", weighs in on the salt debate, calcium balance and keys to longevity. Don't miss these phenomenal insights from one of the all-time leaders in nutritional science.

Paleo Nutrition "Lay-Ups" in This Episode (simple, easy, actionable items) 

1) "Eat Real Food" - Eat grass-fed and wild game meats, pastured chicken and eggs, wild fish and seafood along with plentiful veggies and modest amounts of fruit and starchy tuberous carbs like yams, yucca, carrots, etc.

2) Eliminate All Dairy & Gluten

3) Avoid Processed Paleo Foods & "Fat Bomb" Desserts

Paleo "Performance Hacks" From This Episode

1) Adjust your "macros" according to your lifestyle and activity level. More activity, more carbohydrates; less activity; fewer carbohydrates.

2) Salt - If you eat natural un-adulterated foods it's difficult to obtain more than 2,000mg of sodium in your diet. For longevity purposes, this is highly beneficial. (Dr. Bubbs note - stay tuned for more discussion on this topic around athletes and keto diet followers).

3) Bacon - Yes, it tastes great...but it's not Paleo. Eat in moderation (85/15 Rule)

Coffee Talk
