Fueling Your Fitness: Why Women Should Never Skip Pre-Workout Nutrition

calderkristina

Perimenopause is the transitional phase leading up to menopause, characterized by changes in menstrual cycle patterns and hormone levels, specifically a decline in estrogen. The hormone fluctuations during this period can have various physiological and metabolic implications. Here's why perimenopausal women might consider avoiding working out in a fasted state:

  1. Hormonal Fluctuations and Energy Levels: During perimenopause, the fluctuations in estrogen and progesterone can lead to energy dips, mood swings, and disrupted sleep patterns. Exercising in a fasted state can further exacerbate feelings of fatigue and energy depletion.

  2. Muscle Preservation: As estrogen levels decline, women are at a higher risk of losing muscle mass. Exercising in a fasted state can increase the risk of muscle protein breakdown. To preserve muscle, it's beneficial to have a source of protein before workouts.

  3. Bone Health: Declining estrogen levels also impact bone density. Fasted workouts can lead to a more pronounced acidic environment in the body, which, over time, might be detrimental to bone health. Proper nutrition can help buffer this acidic environment.

  4. Metabolic Changes: Some studies suggest that perimenopausal women may experience changes in insulin sensitivity. Exercising in a fasted state can lead to low blood sugar levels, leading to symptoms like dizziness, light-headedness, or even fainting.

  5. Stress and Cortisol: Perimenopause can be a stressful time for many women, both physically and emotionally. Fasted workouts can elevate cortisol (the stress hormone) levels. Chronic elevation of cortisol can have various negative implications, including weight gain, especially in the abdominal area.

  6. Mood and Cognitive Function: Many women report mood swings, anxiety, and even memory or concentration issues during perimenopause. Proper nutrition, including a balanced intake of essential fatty acids, amino acids, and glucose, can support mood and cognitive function. Exercising on an empty stomach might not provide the necessary fuel for optimal brain function.

  7. Weight Management: While some believe fasted workouts can promote fat loss, the evidence is mixed. For perimenopausal women, the potential muscle loss from fasted workouts might offset any benefits of slightly increased fat oxidation. Moreover, muscle mass is crucial for maintaining a healthy metabolic rate.

It's essential to recognize that every woman's experience of perimenopause is unique. While these are general considerations, some women might feel okay exercising in a fasted state. However, given the physiological changes during this period, it's always advisable to approach fasted workouts with caution and to consult with healthcare professionals about any significant changes in exercise or nutrition habits.



Pre-Workout Macronutrient Recommendations:


1. Carbohydrates: They are the primary fuel source for high-intensity workouts. Consuming carbs before a workout can help ensure that muscle glycogen stores are adequately filled.

  • Amount: About 30-60g of carbohydrates 30 minutes to an hour before the workout. The exact amount can vary based on the workout's intensity and duration.

  • Type: Opt for easily digestible sources, especially if eating just before the workout. Examples include bananas, rice cakes, or a smoothie with fruits.

2. Protein: Consuming protein before a workout can help reduce muscle protein breakdown during the exercise.

  • Amount: About 20-25g.

  • Type: Lean sources like chicken, turkey, tofu, or a protein shake.

3. Fats: Since fats are digested slowly, consuming a large amount right before a workout can lead to discomfort. However, if your pre-workout meal is 2-3 hours before exercising, including a moderate amount of fats is fine.

  • Amount: Keep it low if eating just before the workout. If eating 2-3 hours prior, you can include about 10-15g of healthy fats.

  • Type: Avocado, nuts, seeds, or olive oil.


Post-Workout Macronutrient Recommendations:


1. Carbohydrates: Replenish glycogen stores depleted during the workout.

  • Amount: The recommendation is usually a ratio of 3:1 or 4:1 carbs to protein for endurance workouts. For resistance or strength training, a 2:1 ratio can suffice.

  • Type: Fast-digesting carbs like rice, potatoes, or fruits can help with quicker recovery.

2. Protein: Aids in repairing and building muscle tissue.

  • Amount: About 20-30g.

  • Type: Whey protein (for a quick amino acid release), casein (for a sustained release), eggs, chicken, or fish.

3. Fats: They're not as crucial post-workout as carbs and protein. However, adding some healthy fats can be beneficial, especially if the post-workout meal is also a regular meal.

  • Amount: Around 10-15g, but it's flexible based on individual needs and goals.

  • Type: Avocado, nuts, seeds, or fatty fish like salmon.

Remember, these are general guidelines. Individual needs can vary based on body weight, metabolism, fitness level, and specific goals (e.g., muscle gain, fat loss, endurance training). It's always beneficial to work with a nutritionist or dietitian to tailor recommendations to personal needs.
