Literature Reviews have been very popular. Thus, 2024 will start with science update.

1) Time restricted eating patterns are known to help physiology and metabolism by initiating a pause in the action of mTOR and muscle synthesis as well as inducing autophagy. Autophagy is critical to the clearance of broken or damaged cells following injury or disease. How does circadian biology play into this reality? From Cell Metabolism: “Circadian disruptions impact nearly all people with Alzheimer’s disease….plus a discussion on water, dehydration and prevention as well as a recipe of the week.

Briana Pobiner PhD
This weeks guest is super interesting. Briana Pobiner is a paleoanthropologist whose research centers on the evolution of human diet with a focus on meat-eating. Briana has a BA from Bryn Mawr College, where she created her own major called Evolutionary Studies. Then she completed a Masters degree followed by her PhD in Anthropology from Rutgers University. Briana is also an Associate Research Professor of Anthropology in the Center for the Advanced Study of Human Paleobiology at the George Washington University.
She has done fieldwork in Kenya, Tanzania, South Africa, and Indonesia and has been supported in her research by the National Geographic Society, the National Science Foundation and the Society for American Archaeology. We discuss some of her favorite field moments including a run in with a white rhino as well as discovering fossil bones that were last touched, butchered and eaten by one of her 1.5-million-year-old ancestors. Since joining the Smithsonian in 2005 to help put together the Hall of Human Origins, in addition to continuing her active field, laboratory, and experimental research programs, she leads the Human Origins Program’s education and outreach efforts which includes managing the Human Origins Program’s public programs, website content, social media, and exhibition volunteer training. Briana has also more recently developed a research program in evolution education and science communication. She is the recipient of the 2021 American Association of Biological Anthropologists and Leakey Foundation Communication and Outreach Award in Honor of Camilla Smith, and a 2021 National Center for Science Education Friend of Darwin award.

Donald Layman is currently a Professor Emeritus at the University of Illinois Urbana-Champaign College of Agricultural, Consumer and Environmental Sciences in the department of Food Science & Human Nutrition. Dr. Laymen earned his Bachelors Degree in Science in Chemistry and Masters Degree in Science in Biochemistry at Illinois State University. He then completed his Doctorate Ph.D. in Human Nutrition Nutrition and Biochemistry at the University of Minnesota.
His laboratory is working to define protein and amino acid requirements and the interrelationship between dietary protein and carbohydrates in adult health. The research is focused on the impact of diet and exercise on adult health problems of obesity, type 2 diabetes and the Metabolic Syndrome. Exercise is of obvious importance to health in maintenance of lean body mass, energy expenditure and weight control. Surprisingly little is known about amino acid requirements during exercise or the impact of amino acids on metabolic regulation. His group has helped to define roles of the branched chain amino acids (BCAA) in skeletal muscle metabolism. BCAA provide an important energy source for muscle during exercise and also serve as a critical regulator of muscle protein synthesis during recovery. During exercise, oxidation of BCAA increases, resulting in production of the amino acid alanine and a rapid decline in plasma levels of BCAA. Amino acid supplements prevent this decline in plasma amino acids, enhance recovery of muscle protein synthesis and interact with insulin to help stabilize blood glucose. They are continuing this research to define mechanisms for control of muscle protein synthesis and differences in dietary protein needs for men versus women and for adults with sedentary versus active lifestyles.
A very important conversation for all to understand. All ages are impacted by this knowledge.
