Happy Wednesday, all!

A lot of you really loved reading what our in-house nutritionist, Laura Jennings, had to say about abdominal weight gain a couple of weeks ago (so much, in fact, that I've stored it for any of you who may have missed it HERE).

And so, due to popular demand, I'd like to welcome Laura back for the 53rd edition of The Absolute Scoop!

Today, she is bringing her skills to The Scoop to help us understand why we should be thinking about our protein intake during perimenopause.

Why You Should Be Prioritising Protein In Perimenopause

Written by Laura Jennings - Deakin Researcher and Registered Nutritionist

Menopause is defined by twelve consecutive months without menstruation, marking the natural end of our reproductive years. In the UK, the average age for menopause is 51. However, many experience perimenopause—the transitional period before menopause—between the ages of 45 and 55, though it can begin as early as the late thirties and early forties.

During perimenopause, the amount of estrogen in a woman’s body is usually 20-30% higher than it was before perimenopause and the level of estrogen fluctuates unpredictably.

At the same time, your progesterone levels steadily decrease and can plummet further if you’re dealing with high stress, creating a hormonal rollercoaster. Symptoms vary among women but often include hot flashes, insomnia, night sweats, mood swings, weight gain, brain fog, and low libido.

You might be wondering, what does protein have to do with all this?

The good news is that even small dietary changes, especially focusing on increased protein intake, can significantly impact the frequency and severity of these perimenopausal symptoms. Researchers suggest that the body’s protein requirements increase during perimenopause due to hormonally-induced tissue protein breakdown.

If these needs aren’t met, women may consume excess calories from other sources in what is known as the Protein Leverage Effect, which can contribute to weight gain during perimenopause. This brings us to our first point about why protein becomes particularly important during perimenopause…

Weight Management

Protein is more satiating than fats and carbohydrates, helping you feel fuller for longer. According to Lauren Curtain, a Chinese Medicine Practitioner, women’s metabolism also undergoes changes during perimenopause and menopause, often tending more towards metabolic dysfunction. Energy expenditure typically decreases during menopause, owing to the loss of ovarian function and decreases in muscle mass.

Curtain suggests that emphasising protein intake can assist with supporting metabolism. Protein coupled with resistance exercise helps preserve muscle mass, which is important for maintaining metabolic rate and physical strength. Incorporating more protein into your meals can help control appetite and reduce overall calorie intake.

Improved Mood

Protein breaks down into glucose more gradually than carbohydrates and fats.

When you consume foods high in refined carbohydrates, your blood sugar levels can spike rapidly, leading to a surge of energy and feelings of euphoria. However, what goes up must come down, and these blood sugar highs and lows can cause significant mood swings.

The initial spike can make you feel hyper and upbeat, but as your blood sugar drops, you might experience sadness, frustration, or anger. Protein’s gradual release of glucose into the bloodstream helps prevent these extreme fluctuations, promoting consistent energy levels and emotional stability.

Distributing protein evenly throughout the day is an effective strategy for balancing blood sugar and managing perimenopausal mood swings.

Additionally, amino acids from protein-rich foods are essential for neurotransmitter production, which is critical for mood regulation. For instance, tryptophan, an amino acid found in protein, helps produce serotonin, a neurotransmitter that influences mood and sleep7.

Better Bones

Estrogen is crucial for bone health, and its decline during menopause can lead to a significant decrease in bone density—around 25% of women experience accelerated bone mass loss, increasing the risk of osteoporosis.

Protein plays a vital role in bone strength by supporting the synthesis of bone matrix, which is essential for maintaining bone structure and resilience.

Additionally, some proteins, such as soy-based products like tofu and tempeh can support the body’s natural production of IGF-I, a hormone that promotes bone growth. Studies consistently indicate that higher protein intake is associated with better bone density and a reduced risk of fractures.

Ensuring a diet rich in high-quality protein can therefore be a critical strategy for preserving bone health during and after menopause.

Muscle Mass Maintenance

As estrogen levels decline during menopause, women often experience a loss of muscle mass, which contributes to a slower metabolism and increased body fat deposition. Protein plays a crucial role in muscle repair and growth, serving as the building blocks for muscle tissue.

Adequate protein intake is essential for preserving lean body mass, which is critical for maintaining strength, mobility, and overall metabolic health. Research consistently demonstrates that higher protein consumption can help mitigate muscle loss during aging and support healthy body composition changes associated with menopause.

Supple Skin

Protein is essential for skin health during perimenopause, especially as collagen production declines. Collagen, a structural protein, maintains skin elasticity and firmness, but its production decreases with age, leading to wrinkles and sagging skin.

Amino acids, the building blocks of protein, are crucial for collagen synthesis. Ensuring adequate protein intake provides the necessary amino acids to support and maintain collagen levels, helping to preserve skin’s strength and youthful appearance during the perimenopausal transition.

How Much Protein Do You Need?

The Recommended Dietary Allowance (RDA) for protein in the UK is around 45g per day for women, but during menopause, you might benefit from slightly higher intake.

Aiming for 1 to 1.2 grams of protein per kilogram of body weight is a good place to start. That means for a woman weighing 70 kg this translates to approximately 70-84 grams of protein per day.

Best Sources of Protein

Plant-Based Proteins: Beans, lentils, tofu, tempeh, and edamame are great options for vegetarians and vegans.
Nuts and Seeds: Almonds, chia seeds, and hemp seeds offer protein along with healthy fats and fibre.
Whole Grains: Quinoa, farro, and bulgur are grains that add protein and other nutrients to your diet.
Protein powders, offer a convenient and effective way to supplement your protein intake, especially when time is limited, and you’re on-the-go.

Conclusion

Embracing a protein-rich diet can greatly alleviate your menopausal journey by supporting muscle mass, bone health, mood stability, weight management, and skin health.

Remember, it’s not just about increasing protein intake but integrating it into a well-balanced, nutritious diet. Power up with protein and navigate perimenopause with strength and vitality!
