Beyond the Bro-Science: Rethinking Exercise and Nutrition for Women Over 40
For decades, fitness advice has often been presented as one-size-fits-all. Yet, emerging research, particularly concerning women over 40, is challenging long-held beliefs about optimal training and nutrition. The idea that training with lower glycogen stores is inherently dangerous for women is increasingly being questioned, with experts emphasizing the body’s natural response to stress.
The Misunderstood Stress Response
The notion of “harmful stress” associated with exercising in a slightly depleted state is often misleading. According to Kerstin Brismar, professor of diabetes research at Karolinska Institutet, “Calling it ‘harmful stress’ is misleading. During exercise, the stress signal is part of the process.” Both men and women experience this physiological response, and it’s not unique to any gender, as highlighted by nutritionist Ellinor Nilsson.
Fueling Performance: It’s Not About Deprivation
While training fasted can be effective for some, it’s not always optimal. Nilsson suggests that a small amount of fuel before a workout can make a significant difference, particularly for strength training. “If you’re strength training and wish to get the most out of your session, having a little energy in your body can be beneficial.” This could translate to an extra repetition or improved overall performance, leading to better long-term results.
The Protein Priority: Why It Matters More With Age
As women approach their 40s and 50s, the body’s ability to build muscle naturally declines. This necessitates a greater focus on protein intake. Protein synthesis becomes less efficient, meaning a higher intake per kilogram of body weight may be required to maintain and build muscle mass. Current recommendations for those engaged in strength training often fall within the range of 1.2–1.6 grams of protein per kilogram of body weight daily.
Carbohydrates: The Often-Overlooked Component
In the ongoing nutrition debate, protein often takes center stage, but carbohydrates are equally crucial. They serve not only as a primary fuel source but also influence hormones that stimulate muscle growth. Brismar emphasizes, “You shouldn’t be afraid of calories or carbohydrates if you’re training hard.” Restricting carbohydrates too severely can actually hinder the benefits of exercise.
The Importance of Consistent Training
consistent training is paramount. Brismar points out that muscle mass decreases rapidly without regular exercise, regardless of dietary choices. And even with a perfect diet, building muscle is challenging without sufficient physical activity.
Did You Know?
Alcohol consumption can impact blood sugar levels and potentially lead to hypoglycemia. The body processes alcohol at a consistent rate, approximately 0.1 g of alcohol per kilogram of body weight per hour. Be mindful of this when considering post-workout recovery or evening activities.
FAQ
- Is it dangerous to train with low blood sugar? Short periods of low blood sugar during wakefulness are generally not harmful.
- How much protein do I need if I strength train? A common recommendation is 1.2–1.6 grams of protein per kilogram of body weight daily.
- Are carbohydrates vital for muscle growth? Yes, carbohydrates provide fuel and influence hormones that support muscle development.
