Overview
This episode of the Mel Robbins Podcast, featuring Dr. Stacy Sims, addresses the shortcomings of male-centric fitness and nutrition advice for women. Dr. Sims, an expert in exercise physiology, explains the biological differences between men and women and provides practical, science-backed strategies for women to optimize health, body composition, and stress resilience.
Gender Differences in Fitness and Health
- Most fitness and nutrition guidelines are based on male data and generalized to women, leading to poor outcomes for women.
- Women are biologically distinct from men in muscle composition, hormone cycles, and stress responses.
- Products and fitness advice are often "shrink and pink" versions for women, which is insufficient and misguided.
Key Fitness and Nutrition Mistakes for Women
- Following male-centric advice (e.g., fasted training, high cardio, intermittent fasting) often leads to fatigue, increased fat, and lack of progress for women.
- Skipping breakfast or exercising on an empty stomach increases stress hormones, leads to muscle loss, and promotes fat storage.
- Women need a small amount of food, especially protein, before morning exercise to optimize energy, metabolism, and recovery.
Evidence-Based Recommendations for Women
- Prioritize eating 30 grams of protein or a small meal (protein coffee, yogurt, oats) first thing in the morning.
- Split breakfast if not hungry early, and focus on steady eating opportunities throughout the day.
- Align circadian rhythms by eating earlier and avoid late-night snacks; this lowers cortisol, improves sleep, and supports metabolic health.
- Avoid fixating on thinness; building muscle improves body composition, bone health, and long-term cognitive resilience.
Exercise and Strength Training Guidance
- Strength training is essential for women at all ages to maintain muscle, bone, and cognitive health.
- Women's muscles fatigue less quickly, so shorter rest periods between sets are effective.
- In mid-30s and beyond, shift to heavy, low-rep (6–8 reps) strength training to offset hormonal changes.
- High-intensity interval (sprint) training is more effective and time-efficient than excessive cardio.
- Newcomers should focus on movement quality and community; start with bodyweight and simple at-home routines before progressing.
Environmental and Recovery Strategies
- Women benefit from moderately cool water for cold exposure (55–60°F/15–16°C), while ice baths may be too stressful.
- Sauna use (10–15 minutes, twice weekly) improves cardiovascular health, metabolism, and stress resilience.
Supplement and Nutrition Advice
- Creatine (3–5g daily) is safe and beneficial for women's brain, bone, and muscle health.
- Consistency and simple preparation (ready snacks, protein options) help maintain nutrition amid busy schedules.
- Focus on nutrient-dense, minimally processed foods, following a "grandparent diet" model.
Empowerment and Mindset Shifts
- Encourage body positivity and empowerment for women in fitness spaces.
- Community and support are key to sustaining strength training habits.
- Shift emphasis from appearance to functional strength, resilience, and long-term health.
Decisions
- Women should eat a small amount of protein or food before morning exercise.
- Strength training, especially heavier low-rep lifting, is recommended for women over 35.
- Replace excessive cardio with strength and high-intensity intervals.
Action Items

- TBD – All listeners: Share science-based advice and body positivity with women and girls in your life.
- TBD – All listeners: Prepare nutrient-dense snacks and simple meals for busy days.
Recommendations / Advice
- Do not follow generic or male-oriented fitness trends; tailor approaches to female biology.
- Focus on health, strength, and resilience over thinness or scale weight.
- Use online resources or community programs to learn movement and strength basics.
- Consider creatine supplementation for comprehensive health benefits.
