Today, I am thrilled to connect with Dr. Zelana Montminy, who holds a doctorate in clinical psychology. Dr. Montminy developed her career speaking for and advising Fortune 500 companies and academic institutions. She regularly appears on Good Morning America, The Today Show, and Access Hollywood.  In our conversation, we unpack the concept of novelty bias, exploring how it shapes our neuroanatomy and compromises our conscientiousness. We debunk the myths of multitasking and task switching, and dive into generational shifts and our disconnection from ourselves and the world around us. We also highlight the vital role of the gut-brain connection, share practical social tools such as the Pomodoro Technique, and examine the transformative power of curiosity and awe.  This discussion with Dr. Zelana Montminy is an exciting and forward-thinking exploration of how our brains and bodies are programmed for distraction. Her book, Finding Focus, also offers a compelling narrative to help us get back on track. IN THIS EPISODE, YOU WILL LEARN: What is novelty bias?  How technology impacts our mental health and ability to empathize in the long term  Why are we seeing a loss of conscientiousness in the younger generations, and why do older generations tend to feel and process things more intensely? How constant exposure to technology affects the ability of the brain to process information  Generational differences in information processing The detrimental effects of multitasking on productivity and focusing ability, and the benefits of single-tasking and staying in the present moment How being in a constant state of fight or flight dysregulates the nervous system  The importance of nutrition, sleep, and hydration for mental health Tools and strategies to boost your ability to focus  The value of curiosity for problem-solving, resilience, and health Connect with Cynthia Thurlow   Follow on X, Instagram & LinkedIn Check out Cynthia’s website Submit your questions to [email protected] Join other like-minded women in a supportive, nurturing community: The Midlife Pause/Cynthia Thurlow  Cynthia’s Menopause Gut Book is on presale now!

Welcome to today’s Midlife Minute episode. I've received a wave of questions about the best ways to fuel workouts and how to recognize signs that you're not eating enough to support your exercise routine. This topic is particularly relevant because many women in my community have practiced fasting, intermittent fasting, or other forms of time-restricted eating for years, which can sometimes lead to chronic under-fueling. Stay tuned to learn how to spot the signs of under-fueling and ensure your body gets the energy it truly needs. IN THIS EPISODE, YOU WILL LEARN: How practicing intermittent fasting or time-restricted feeding for years can lead to energy deficits and poor workout recovery What happens to you when you’re middle-aged and your protein intake is too low? Why women have a higher risk of chronic under-fueling consequences as their progesterone, estradiol, and testosterone decrease with age  How chronically elevated cortisol negatively impacts women’s muscles, metabolism, and insulin sensitivity The importance of maintaining your muscles as you age Signs that indicate you may be under-fueling Strategies to support your health and performance in middle age Connect with Cynthia Thurlow   Follow on X, Instagram & LinkedIn Check out Cynthia’s website Submit your questions to [email protected] Join other like-minded women in a supportive, nurturing community: The Midlife Pause/Cynthia Thurlow  Cynthia’s Menopause Gut Book is on presale now!

Today, I had the honor of connecting with Ashley Koff. She is a leading voice in personalized nutrition and the founder of the Better Nutrition Program. With over 25 years of experience and the groundbreaking GLP-1 Optimization System to her name, she’s helped redefine how we approach sustainable weight health. In our conversation, we dive into how her book reframes the concept of healthy weight. We explore integrative perspectives on digestive health and GLP-1s, why many women blame themselves when they struggle to lose weight, and how Ashley’s framework helps them remove that self-blame. We also discuss issues surrounding info-besity and the “less is more” approach, natural ways to support appetite regulation and satiety signaling, key areas of digestive health, and the importance of detoxification. Ashley also shares the red flags she sees in women who are undernourishing themselves or over-fasting, things to consider when you want to stop taking GLP-1s, and her opinions on new drug therapies. Join us for today’s thought-provoking and insightful conversation around metabolic health and weight-loss resistance for women in middle age, perimenopause, and menopause. IN THIS EPISODE, YOU WILL LEARN: The interconnection that exists between digestion, hormones, and metabolic signaling How the hormonal fluctuation that occurs in perimenopause disrupts women's digestion What drives satiety?  How GLP-1 medications simply amplify, extend, or mimic an existing communication loop within the body rather than creating new pathways Why do women blame themselves when they cannot lose weight? How info-besity blocks the body from doing what it is naturally designed to do  Why detoxification is essential for supporting natural digestive and metabolic processes The red flags that indicate undernourishment or over-fasting in women What you need to think about before stopping GLP-1s Bio: Ashley Koff, RD, is the USA Today bestselling author of⁠ Your Best Shot⁠ (HarperOne) and founder of⁠ The Better Nutrition Program⁠ (BNP). An acclaimed weight-health expert and practitioner for more than 25 years, Koff is leading a transformative movement in personalized nutrition, turning “better, not perfect” choices into practical, sustainable strategies that deliver real outcomes. Your Best Shot introduces weight-health hormones (GLP-1, GIP, CCK, PYY) as the regulators of weight health, offering the first-ever assessment of their function and a personalized optimization system—shot or not.

I am delighted to reconnect with Dr. Jason Fung today. He is a trained nephrologist and world-leading expert on intermittent fasting and metabolic health. He has authored multiple books, including the New York Times best-seller, The Obesity Code, The Diabetes Code, and, more recently, The Hunger Code.   In our conversation today, we unpack the obsessive focus on the calories-in, calories-out model, which is neither practical nor effective. We explore the root causes behind the narrow-minded thinking that calories alone drive obesity, differences between types of hunger and conditioned responses, how hormones affect other hormones, and lessons about GLP-1s. We examine the critical importance of fiber and protein, and offer clarity around carbohydrates. We also cover the impact of meal timing, sleep, and circadian biology, the fat thermostat and sympathetic tone, nutrition, stress, and mindful eating, and dive into the issue of ultra-processed foods. Join us for an insightful conversation that challenges conventional wisdom and offers a nuanced and sustainable approach to understanding hunger, metabolism, and long-term health. IN THIS EPISODE, YOU WILL LEARN: “Calories in, calories out” framework is technically correct, but practically useless How the homeostatic, hedonic, and conditioned hunger types differ Dr. Fung shares his take on GLP-1 medications How fiber stimulates natural GLP-1 production Processed and natural carbohydrates produce vastly different glucose and insulin responses.

Today, I am thrilled to connect with Dr. Sonya Jensen, a naturopathic physician on a mission to transform how women understand themselves and their bodies. She believes women are central to their families and communities, and by supporting women, we create a ripple effect that supports the whole. In our conversation, we explore the sense of selfishness many women feel when advocating for their needs, and why choosing ourselves, especially in midlife, is essential. We discuss science-versus-soul transformations, gestational silence and trauma, and the physiological effects shaping this generation and those to come. We also unpack how stress impacts the immune system and autoimmunity, why stress reduction techniques are the key to vagus nerve activation, the link between mental health and hormones, womb-wisdom and generational influences, how grief and sadness can influence us profoundly, and the value of trusting our intuition and embracing the gifts of aging. I know you will enjoy this discussion with Sonya Jensen. She shares a gentle, loving, and kind message for women- one that is well worth reflecting upon. Be sure to keep an eye out for her upcoming book, Heal Your Hormones, Reclaim Yourself, scheduled for release in early 2026, where she connects hormonal chaos, emotional overload, and relationship pain through her integrative method. After the recording, Dr. Jensen noted a clarification: there were 50 famines in total during British rule in India, not 50 famines in a single year. IN THIS EPISODE, YOU WILL LEARN: How awareness practices can help you become more physically regulated when things feel overwhelming Why friable emotions are not due to personal failure or a faulty mindset How to reconnect with your body The benefit of body-based practices for supporting nervous system regulation    What is womb wisdom?
