In This Episode We Discuss Distinguishing between COVID-19 (disease) and the actual novel coronavirus (SARS-CoV2) What is different about this specific coronavirus compared to others This coronavirus has a respiratory droplet transmission The difference between respiratory droplet and airbourne transmission Time from exposure to SARS-CoV-2 to symptom The disease mechanism Current case reports on those hospitalized In those who have recovered, do we know yet whether they can be reinfected or if they have established immunity? Is the severity of the disease impacted by the length or magnitude of the exposure? On average, for someone infected how many people will they likely infect. How it compares to other viruses in terms of lethality and transmissibility Why social distancing (and potentially self- isolation) is so important Impact on healthcare system Mortality rate is not inherent to the virus alone, but mediated by how the healthcare system holds up, as well as population demographics, etc. Response needed now: a) public health/governmental; b) individuals (context dependent)

Dave Feldman is a software engineer and runs the Cholesterol Code website. In 2015 Dave adopted a low-carb high-fat diet, which improved his overall health. However, upon seeing his LDL-cholesterol skyrocket, he set out learn all he could about blood lipids and health. Dave has gained prominence as a "LDL-skeptic" and promoter of his "lipid triad" hypothesis. This lipid triad relates to a situation where one sees high LDL-C, high HDL-C and low triglycerides. Dave hypothesises that in such a context, the high LDL-C does not confer high risk of cardiovascular disease. This is counter to the current consensus position of the lipid hypothesis, where LDL plays a causal role in atherosclerosis development.

Dr. Chris Melby is a Professor in Food Science and Human Nutrition at Colorado State University. He has a long-standing research focus on the interplay between dietary eating patterns and exercise/physical activity in regard to energy metabolism and positive and negative energy balance. In recent times Dr. Melby has published work on the relationshop between energy flux and the probability of maintaining a previous loss of body weight. Long-term maintenance of weight loss requires sustained energy balance at the reduced body weight. This could be attained by coupling low total daily energy intake (TDEI) with low total daily energy expenditure (TDEE; low energy flux), or by pairing high TDEI with high TDEE (high energy flux).
