Dr. Stacy Sims, a leading expert in exercise physiology and nutrition science, has dedicated her career to revolutionizing how women approach training and nutrition. Her work challenges the conventional, male-centric approach to fitness, offering evidence-based strategies tailored to the unique physiological needs of women across different life stages. Drawing from her appearances on podcasts like the Huberman Lab and ZOE Science & Nutrition, along with her extensive research, this article synthesizes Dr. Sims' key insights, providing actionable guidance for women seeking to optimize their health, performance, and longevity.
The Need for Female-Specific Strategies
Historically, exercise and nutrition research has predominantly focused on men, leaving a significant gap in understanding the specific needs of women. Dr. Sims emphasizes that women's hormones, menstrual cycles, and life stages necessitate tailored approaches to training and nutrition. Ignoring these differences can lead to suboptimal results, increased risk of injury, and even adverse health outcomes.
Understanding the Hormonal Cycle
One of Dr. Sims' core principles is understanding and tracking the menstrual cycle. Hormonal fluctuations throughout the cycle significantly impact energy levels, metabolism, and recovery. By tracking their cycles, women can identify patterns in performance and recovery, allowing them to adjust their training and nutrition accordingly.
High Hormone Phase (Luteal)
The luteal phase, occurring post-ovulation to menstruation, is characterized by elevated levels of cortisol and increased inflammatory responses. During this phase, Dr. Sims recommends prioritizing nutrition and avoiding intense training to manage stress levels.
Impact of Oral Contraceptives
Dr. Sims also addresses the impact of oral contraceptives on training adaptations. Oral contraceptives can affect inflammation, oxidative stress, and hormonal balance, potentially influencing performance and recovery. Women using oral contraceptives should be particularly mindful of their nutrition and training strategies.

Fueling Strategies for Optimal Performance and Recovery
Dr. Sims emphasizes the importance of "fueling for the task at hand," tailoring nutrition to support training intensity and recovery needs. She highlights the critical role of protein, carbohydrates, and fats in optimizing women's health and performance.
Protein Intake
Protein is crucial for muscle maintenance, growth, and overall health. Dr. Sims recommends that women in their reproductive years consume around 1 to 1.1 grams of protein per pound of body weight daily. This translates to approximately 35 grams of high-quality protein within 45 minutes post-workout. Older women may require up to 60 grams due to anabolic resistance, a reduced ability to build muscle with age.
Pre-Workout Fuel
Consuming protein and carbohydrates before a workout is essential for stabilizing blood sugar and curbing cortisol levels. Dr. Sims suggests having 15 grams of protein plus 30 grams of carbohydrates (e.g., a protein-coffee shake) before training sessions.
Avoiding Fasted Workouts
Fasted workouts can increase cortisol levels, leading to higher stress and reduced recovery. Dr. Sims advises against training on an empty stomach, especially when cortisol levels are already elevated.
Carbohydrates and Fats
Dr. Sims recommends sourcing carbohydrates from colorful vegetables, fruits, and whole grains to support gut health and hormone balance. Healthy fats from nuts, avocados, and olive oil should also be included in the diet.

The Importance of Calories
For overall health and performance, it is vital that women consume enough calories, especially from proteins. The concept of "fueling for the task at hand" is highlighted, suggesting slight caloric deficits away from training times can help with fat loss while still supporting recovery. It's important to avoid getting overly focused on calorie counting, which can lead to neurotic behaviors and eating disorders.
Exercise Recommendations for Different Life Stages
Dr. Sims provides specific exercise recommendations tailored to different life stages, emphasizing the importance of resistance training, high-intensity interval training (HIIT), and polarized training.
Women Aged 20-40
For women in their 20s and 30s, Dr. Sims recommends focusing on resistance training and high-intensity workouts for metabolic control and cognitive health. Learning complex movements and integrating resistance training three to four times a week is ideal. High-intensity interval training (HIIT) and sprint interval training are essential for improving metabolic control, insulin sensitivity, and brain health.
Women Over 50
Women over 50 should emphasize jump training, heavy resistance training, and sprint interval training to maintain bone density and strength.
Resistance Training
Forming the bedrock of fitness, resistance training is highly recommended. For younger women, learning complex movements and integrating resistance training three to four times a week is ideal.

High-Intensity Interval Training (HIIT)
High-intensity interval training (HIIT) and sprint interval training are essential for improving metabolic control, insulin sensitivity, and brain health.
Polarized Training
A balance between high-intensity training and lower-intensity activities (like Zone 2 aerobic work) is suggested for optimal health.
Enjoyable Exercise
Engaging in enjoyable forms of exercise, like cycling or walking in nature, is also important for mental well-being.
Exercise Timing
Exercise can be optimized by timing workouts 30 minutes after waking, three hours after waking, or 11 hours after waking to improve performance and reduce injury. Exercising first thing in the morning can help establish a consistent wake-up time due to the body's anticipatory response. There's a link between exercise intensity and sleep need; too much intense exercise can lead to feeling unrested even with sufficient sleep.
Supplementation Strategies
Dr. Sims also discusses the potential benefits of specific supplements for women, including creatine, vitamin D3-K2, adaptogens, magnesium glycinate, and omega-3s.
Creatine
Supplementing with 5-10 grams of creatine monohydrate daily is beneficial for muscle strength and brain health.
Vitamin D3-K2
Vitamin D3-K2 should be taken in the morning for overall and bone health, especially if sunlight is limited.
Adaptogens
Adaptogens like ashwagandha or holy basil can help manage cortisol and stress.
Magnesium Glycinate
Magnesium glycinate can promote better sleep and relaxation.
Omega-3s
Omega-3s from fish or algae sources can help control inflammation.
Iron
Iron levels can drop during menstruation, leading to fatigue. Women should consider taking iron supplements during this time to maintain adequate levels. You can always check ferritin levels with your doctor to determine if this approach is right for you.
Urolithin A
Urolithin A is highlighted for its benefits on mitochondrial health and muscle strength. Most individuals cannot produce it naturally, making supplementation valuable.
Nutrient Timing and Performance
Nutrient timing plays a significant role in optimizing physical and cognitive performance. Proper nutrient timing around workouts can optimize muscle recovery, energy levels, and performance during exercise. Consuming high-quality nutrients, including vitamins, minerals, probiotics, and fiber, is essential for cognitive functions like memory, focus, and the ability to learn new things. Aligning food intake with the body's circadian rhythms (eating during daylight hours) supports better digestion and metabolism, which can positively impact both physical and cognitive functions. By strategically timing nutrient intake, especially around periods of activity and rest, you can maximize both physical and cognitive performance effectively.
Endurance Training Fuel
While Dr. Sims does not specifically address gender differences in fueling for endurance training, the general approach to endurance fuel can be applied to both men and women, with considerations for individual metabolic and physiological differences. Elite athletes often combine carbohydrate loading and ketone intake to enhance performance during long bouts of exercise. Carbohydrates replenish glycogen stores, while ketones provide a quick energy source.
Perimenopause and Menopause
Dr. Sims emphasizes that tailoring your fitness routine during perimenopause can prevent many unwanted shifts in metabolism and body composition. Even if youâre younger or postmenopausal, these principles build lifelong strength and vitality.
Cardio
Skip long, steady-state jogs or spins that spike cortisol without much payoff. Instead, they can worsen symptoms like fat gain or poor sleep. Limit High-Intensity Interval Training (HIIT) to 1-2 sessions per week, keeping them short (30 minutes total, including warm-up and cool-down). Go for 80-90% of your max effort in bursts (e.g., 30 seconds sprinting, 2-3 minutes recovery). This promotes glucose uptake, fights inflammation, and supports fat loss without over-stressing your system. Mix low-intensity âZone 2â cardio (like brisk walking or easy cycling) with high-intensity bursts. Aim for about 5 hours of moderate-to-vigorous activity per week (around 1850 MET minutesâthink brisk walks adding up).
Strength Training
Focus on compound moves like squats, deadlifts, push-ups, and rows. Do 5-10 reps per set, leaving 2-3 reps âin the tankâ to keep form sharp. Lift heavy enough to challenge yourselfâthis stimulates your nervous system and builds muscle to offset losses. Add box jumps or stiff-leg landings to boost bone density and power. Start Gradually: Beginners, spend 2 weeks to 4 months mastering form to avoid injuries like frozen shoulder, which are more common in perimenopause due to hormonal changes. Use bodyweight or light weights first.
Nutrition
Aim for 2-2.3 grams per kilogram of body weight daily (e.g., about 140-160g for a 70kg woman), spread across meals every 3-4 hours. Post-workout, get 40-60g of leucine-rich protein (like whey or eggs) within 45-60 minutes. Have 15g protein plus 30g carbs (e.g., a protein-coffee shake) before sessions to stabilize blood sugar and curb cortisol. Source carbs from colorful veggies, fruits, and whole grains for gut health and hormone balance. Add healthy fats from nuts, avocados, and olive oil.
The Importance of Muscle Health
Dr. Sims notes that skeletal muscle health is pivotal for longevity because muscle conditions like sarcopenia begin in muscle tissues before any outward signs of frailty or disease appear. Skeletal muscle acts as a glucose disposal unit, which helps in regulating blood sugar levels and insulin sensitivity. The body has a high rate of protein turnover, where about 300 grams of protein are turned over daily. Efficient turnover supports bodily functions like immune response, enzymatic activities, and other vital processes. Protein has a higher thermic effect compared to carbohydrates and fats, meaning more energy is required to digest, absorb, and use proteins. Dr. Huberman emphasizes that aiming for about 1 gram of protein per pound of ideal body weight ensures the body has enough resources to maintain muscle mass and overall health, thereby promoting longevity and enhanced quality of life
