Life Sciences Entrepreneurship & Price Transparency in Healthcare with Dr. Jeffrey Roh, Susie Kataoka, and Dr. Tony Little
In this first audio/video episode of Ventures, we discuss with Dr. Jeffrey Roh, Susie Kataoka, and Dr. Tony Little the importance of cost and price transparency in healthcare today. We also discuss the current landscape/opportunity for starting new ventures in the life sciences.
COVID-19 Science Logbook (Jan-May, 2020)
This logbook is where I recorded my notes on COVID-19 from January 2020 through May 2020. For future posts on COVID-19 and/or SARS-CoV-2, follow my “COVID-19” topic on my subscribe page.
Coronavirus Disease 2019 (COVID-19): Understanding the epidemiology, biochemistry, and cognitive biases regarding the spread of — and our reaction to — SARS-CoV-2
With so much misinformation out there and understandable concern regarding this disease (COVID-19), and the virus that causes it (SARS-CoV-2), the goal of this article is to help provide a scientific foundation to better process information and decide how to act. I’ll introduce the basics of epidemiology, how epidemiologists around the world are considering and responding to COVID-19, what SARS-CoV-2 is exactly and how it spreads, the status of vaccines and antiviral drug developments, and what cognitive biases are at play as we individually and collectively react to this global pandemic.
The link between acrylamide, coffee, and cancer: Here’s what scientists know (and don’t know)
A judge in California ruled this week that Starbucks, 7-Eleven, and many other businesses that sell coffee need to warn consumers via food labels about the ingestion of acrylamide. California’s Prop 65 states that businesses selling products that contain one or more of 65 chemicals shown by scientists to cause cancer and/or reproductive disease must give customers a “clear and reasonable” heads up.
The Science of Healthy Fats
The world is waking up to the reality that sugar and refined carbohydrates are more to blame for the diseases of western civilization than salt or fats. Still, there remains confusion about the health implications of consuming fat. What does modern research have to say about the effects of saturated fat, omega-3s/6s/9s, and short/medium/long-chain triglycerides? What are nutritionists referring to when they use the term “healthy fats”, and what exactly makes fat healthy versus unhealthy?
The science of salt and electrolytes (are we consuming enough?)
Modern science has revealed that we were wrong (and fooled) yet again. As it turns out, mineral deficiencies are likely more of a problem than we realize, as not consuming enough salt and electrolytes is both easy to do and dangerous for our health.
The Science of Optimal Sleep: Introduction to Nutritional Biochemistry, Part 5
In the previous four articles in this series we looked at fat loss, muscle gain, hydration, and flexibility. Here, we finish the series by turning our attention to sleep.
How to increase muscle flexibility: Introduction to Nutritional Biochemistry, Part 4
In the first three articles in this series we looked at fat loss, muscle gain, and hydration. Here, we turn our attention to the science behind muscle flexibility.
How to stay hydrated (and reduce headaches, hangovers, and fat): Introduction to Nutritional Biochemistry, Part 3
In the first two articles of this series we looked at the science behind how to shrink fat cells and grow muscle cells. Here, we take aim at hydration.
How to grow muscles: Introduction to Nutritional Biochemistry, Part 2
After looking at the science behind how to shrink fat cells in the previous post of this 5-part series, we now turn our attention to muscles and how to increase their size.
The calories vs. hormones debate for shrinking fat cells: It’s both…and it varies from person to person, season to season
So there are pro-macro and anti-macro tribes out there, each with valid arguments. (If you’re not up on the lingo, when a fitness-y person asks “what are your macros?”, they are asking what your daily calories are from carb/protein/fat).
How to shrink fat cells: Practical Nutritional Biochemistry, Part 1
We’re going to laser-beam in this 5-part series on the basic science behind how to shrink fat cells, grow muscle cells, get flexible, stay hydrated, and sleep well. We’ll move quickly and link to a variety of sources for further reading.
The 43+ health benefits of ketogenic dieting (in addition to weight loss)
For those unfamiliar, ketogenic dieting is any diet plan “low-carb” enough to switch your body into a state of producing and burning a significant amount of ketones, specifically acetoacetate (AcAc) and its derivatives beta-hydroxybutyrate (BHB) and acetone. These molecules, especially AcAc and BHB, are used by the brain and other tissues for energy, and facilitate a number of health benefits that I’ll address below.
Summarizing the science behind ketogenic (low-carb) diets
After publishing The Science Behind Fat Metabolism a couple weeks ago, I received a tremendous amount of helpful feedback from scientists, medical professionals, and other health experts. Cheers, Internet. I appreciate the feedback and refinement. I’ve updated the article accordingly and will continue to do so as more comments are submitted. I also got a bunch of questions about low-carb dieting, hence my attempt in this article to summarize the underlying science. As always, if you read anything below that needs changing, let me know and I’ll do so quickly.
The Science Behind Fat Metabolism
The concentration of glucose in your blood is the critical upstream switch that places your body into a “fat-storing” or “fat-burning” state. The metabolic efficiency of either state — and the time it takes to get into one from the other — depends on a large variety of factors such as food and drink volume and composition, vitamin and mineral balances, stress, hydration, liver and pancreas function, insulin sensitivity, exercise, mental health, and sleep.
