Dr. Lauren is a researcher and science communicator specializing in female physiology, exercise, and nutrition, and a former seasoned fitness professional with extensive hands-on experience helping hundreds of women in all stages of life. She is a co-owner of the MASS Research Review, which helps bridge the gap between cutting-edge research and practical fitness strategies for coaches and trainers. Lauren works to dismantle fitness and nutrition myths perpetuated without a scientific basis by fact checking claims made by online influencers. Lauren's scientific expertise and real-world experience as a fitness professional helps practitioners provide evidence-based recommendations to women in all stages of life. If you use social media for any of your health advice, this is an episode you need to hear. Joyce and Lauren explore how health and fitness misinformation spreads online — and why, once it takes hold, it can be surprisingly hard to “unlearn”. They break down how to judge the quality of evidence, including the differences between mechanistic studies, observational research and human clinical trials, and why correlation is not the same as causation. They also tackle some of the major myths Lauren works hard to debunk: fasted training, protein obsession, weighted vests, grip strength, collagen and creatine hype, vibration plates, and the way supplements are often marketed with exaggerated claims. Throughout, Lauren explains what the evidence does (and does not) support — and why mastering the basics matters far more than chasing the latest trend.
