He completed his internship and residency in internal medicine at Michael Reese Hospital in Chicago and then a Fellowship in infectious diseases at the Mayo Clinic. 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.

The release of this episode coincides with the International Day of Women and Girls in Science, which has taken place annually on the 11th February, since 2016. The day recognizes the critical role women and girls play in science and technology. The International Day of Women and Girls in Science is implemented by UNESCO and UN Women, in collaboration with intergovernmental agencies and institutions, as well as civil society partners, that aim to promote women and girls in science. The day's purpose is to promote full and equal access to participation in science for women and girls. In this episode, we look back on a handul of women who have appeared on the podcast over the past 12 months, to highlight the outstanding work and achievements of women in nutrition science and health science research.

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).
