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 38 - Triathlons, Endurance Training & Considerations for Female Athletes w/ Dr. Tamsin Lewis MD

In this episode, Dr. Bubbs sits down with Dr. Tamsin Lewis MD, functional medicine expert and elite endurance athlete, to talk all things endurance training: how she become UK Ironman champion, nutrition and training lessons she learned along the way, the importance of personalized training volumes to maximize results, considerations for female athletes, key biomarkers for assessing recovery and health, and so much more! Dr. Tamsin provides a ton of great tips and actionable insights to help you raise your game.

"Lay-Ups" In This Episode

  1. Gut distress is common in endurance athletes; “periodizing” carb intake can help to mitigate digestive issues.
  2. Individualized training load is crucial for optimizing endurance performance.
  3. Excessive carb restriction for endurance training can tax immunity, adrenals and sex hormones (particularly in females). 

"Performance Hacks" From This Episode

  1. A regular menstrual cycle is not directly related to body-fat (or leanness), but rather how much “stress” your brain perceives on the body.
  2. Genetic predisposition to endurance training can promote significant performance gains over the competition. (See Episode #24 with Athletigen CEO Dr. Jeremy Koenig!).
  3. Low bone density is directly related to low hormone levels (i.e. testosterone) and nutritional status (i.e. calcium, vitamin D, boron, etc.).

About Dr. Tamsin Lewis

Tamsin qualified with honours in Medicine & Surgery at Kings College London in 2004 and was awarded MRCPsych from the Royal College of Psychiatrists in 2009. After years of training in the conventional medical paradigm Tam-sin became disillusioned with the ‘band-aid approach and pharmaceutical dogma which pervaded daily practice in primary and secondary care. During this time she began competing in triathlons, and found her performance improved in direct correlation with the degree to which she optimised key bio-markers through lifestyle, nutrition, supplement and training adjustments. Tamsin spent 4 years as an elite And In 2014 she won Ironman UK as a professional at her first attempt at this distance - having never run a marathon prior - and ‘raison d’être’ is to empower people to redefine the way they think about health.
