He received his PhD in Nutritional Sciences at the University of California, Berkeley in 1993. His postgraduate training included a postdoctoral fellowship in cardiovascular disease epidemiology at Stanford. Dr. Gardner is passionate about two central questions that keep him up at night and get him to jump out of bed most mornings. The first of these is: What can people eat and drink (or avoid/limit) to optimize their health? Dr. Gardner has recently shifted much of his energies to a second and more challenging question: What forces and factors can successfully motivate people to improve their food and beverage choice behaviors? Study Discussed: Gardner et al., 2018 – Effect of Low-Fat vs Low-Carbohydrate Diet on 12-Month Weight Loss in Overweight Adults and the Association With Genotype Pattern or Insulin Secretion: The DIETFITS Randomized Clinical Trial

Ari Snaevarsson currently works as a dietetic technician at a residential treatment center for patients with eating disorders. He graduated from Gettysburg College with his Bachelor's in Health Sciences and worked there also as a research assistant. His Capstone research was titled "How aggressively can hospitalized adolescents with anorexia nervosa be refed to prevent irreversible adverse outcomes or death?" In addition, Ari works, separate from the eating disorder field, as a Precision Nutrition Level 1 certified nutrition consultant at True Fitness & Nutrition. In This Episode We Discuss Defining anorexia nervosa & refeeding syndrome How and why we see severe hypophosphatemia play out What is the current standard of care for hospitalized anorexic patients? Is their alternatives to current standard practice that have potential? What sort of surpluses lead to appropriate rates of weight gain? Differences between whole food refeeds vs. feed tube vs. TPN (intravenous)

Go to the episode page here. Jordan Feigenbaum is an experienced strength coach who also has his medical degree and residency training. In addition to a veritable laundry list of credentials, Jordan is also an elite powerlifter. In This Episode We Discuss Benefits of strength training for health Why aren't recommendations to do resistance training not more widespread in medical practice? Misinterpretation of evidence-based practice Is it better to recommend people do "any exercise they like" or persuade them to strength train?

James Krieger is the founder of Weightology. He has a Master's degree in Nutrition from the University of Florida and a second Master's degree in Exercise Science from Washington State University. He is the former research director for a corporate weight management program that treated over 400 people per year, with an average weight loss of 40 pounds in 3 months. His former clients include the founder of Sylvan Learning Centers and The Little Gym, the vice president of Costco, and a former vice president of MSN. James is a published scientist, author, and speaker in the field of exercise and nutrition. He has published research in prestigious scientific journals, including the American Journal of Clinical Nutrition and the Journal of Applied Physiology. In This Episode We Discuss The recent systematic review and meta-analysis that James co-authored on training frequency and strength gain Volume for strength & hypertrophy: how many sets should you do? How much difference does a calorie surplus make for muscle gain? How much difference does a calorie surplus make for strength? What variables outside of training volume drive results? healthiq.com/sigma

Arthur Lynch is a exercise physiology researcher currently pursuing his PhD at the University of Limerick. His current research focuses on the role of HMB supplementation on hypertrophy and strength performance in well-trained individuals. Arthur is an accomplished drug-free powerlifter, representing Ireland at the last two IPF World Championships and heading there again this year. He is current Irish Powerlifting Ferderation national champion in the -93kg class. Arthur coaches online here at Sigma Nutrition, working with powerlifters of all levels. healthiq.com/sigma

Special guest host Ciaran O' Regan interviews Dr. Israel Halperin about research and application of S&C coaching. Israel is a post-doctoral researcher at Memorial University of Newfoundland. Israel completed his PhD at Edith-Cowan University, Australia in conjunction with the Australian Institute of Sport (AIS). His research centered on the effects coaching feedback has on the performance of resistance trained subjects and combat sport athletes. Israel spent the 3 years working with the four Olympic Combat sports in the AIS Combat Centre as a sport scientist. Over the years Israel has trained many world-class combat sport athletes as an S&C and Muay Thai coach. Israel has international competition experience in Muay Thai, and has spent 2 years in the U.S and a year in Thailand for training and competition purposes. He also holds two black belts. In This Episode We Discuss: Israel's background as athlete, coach and scientist The role of strength and conditioning in open loop sports and the cost to benefit analysis of GPP vs SPP An evidence-based approach to designing combat sports training sessions Becoming comfortable with the uncertainty and chaos of working with humans Humility as a scientist and a coach and being willing to change our views in light of evidence Becoming aware of our biases and what to do about them This episode is brought to you by Health IQ.

Dr. Andy Galpin of CSU Fullerton talks about blending evidence and practice, as well as the potential beneficial and detrimental roles of technology for making training decisions. Andy is a tenured Professor in the Center for Sport Performance at CSU Fullerton. Andy spent 4 years studying the structure and function of human skeletal muscle at the single cell level, a feat which earned him a PhD in Human Bioenergetics in 2011. This also resulted in the friendship with frequent collaborator Dr. Jimmy Bagley and the ability to open up his own "Biochemistry and Molecular Exercise Physiology Laboratory" at CSU Fullerton. He now focuses his attention on teaching classes (Sports Nutrition, Exercise Physiology, Designing Exercise Programs, Applied Strength and Conditioning, Athlete Assessment and Measurement, etc.) and running the BMEP lab (which studies the acute responses and chronic adaptations of human skeletal muscle in response to high force/velocity/power and fatiguing exercise from the whole body, down to the individual muscle fiber and even into the individual DNA. The team does this by taking muscle biopsies from non-athletes and elite athletes from different backgrounds (e.g. normal college student, MMA fighter, Boxer, Weightlifter, etc.) and use highly sophisticated laboratory techniques and equipment to address questions about single fiber "type", size, function, protein quantity, diameter, mitochondria, and myonuclear function. In This Episode We Discuss: Communication of scientific concepts Physiology of the adaptive response Decision-making process for how to decide on whether a specific technological tool is useful to use Assessing readiness to train: in either remote athletes or combat athletes where you can't visually see them for every session This episode is brought to you by Health IQ.
