Nutrition & Exercise tips for Women | Stacy Sims, Phd

Nutrition Timing

Stacy Sims emphasizes the importance of nutrient timing and adequate caloric intake for women, particularly around exercise. She notes that women often experience negative effects from fasted training, such as increased fat accumulation and hormonal imbalances. To combat this, Stacy suggests consuming some food before workouts to signal the brain that nutrition is available, which helps maintain energy levels and hormonal balance 1.

Women do better with some food on board, so it doesn't mean you have to get up at 4:30 and have a big breakfast before you work out at 5:30, but you have something on board that signals the brain that there's some nutrition coming in.

Additionally, she advocates for the 80/20 rule in nutrition, where 80% of the time is spent adhering to a structured diet and 20% is reserved for indulgence without guilt 2.

   

Hormonal Balance

Diet plays a crucial role in hormonal balance, particularly for women experiencing menopause or engaging in athletic activities. Stacy Sims discusses how hormone replacement therapy and contraceptives can influence training and body composition, emphasizing the need for tailored exercise and nutrition plans to maintain lean mass and bone density 3. She highlights the risks associated with low energy availability, such as amenorrhea and increased injury risk, stressing the importance of monitoring menstrual cycles as indicators of overall health 4.

If you are amenorrheic, defined by three months of no period, then you are increased for bone stress fractures, increased risk of inflammatory responses, poor cardiovascular function, poor recovery, and then we see a plateau and a decrease in performance.

Understanding these factors can help women optimize their health and performance.

   

Supplements & Testing

Stacy Sims explores the role of adaptogens and supplements in supporting women's health, particularly in managing stress and hormonal balance. She mentions adaptogens like ashwagandha and rhodiola, which can help modulate cortisol levels and enhance parasympathetic responses 5. For those interested in understanding their hormonal profiles, Stacy recommends specific hormone tests, such as estradiol on day two and progesterone on day 21 of the menstrual cycle, to gain insights into hormonal fluctuations 6.

If you really want to dig down and see like what your hormone profile is, we say get an estrogen or estradiol test on day two and a progesterone test on day 21.
