Navigating Perimenopause: A Recalibration of the Entire Hormone System

Similar to puberty, perimenopause is a recalibration of our entire hormone system.

As we reach our mid-30s, our bodies begin a hormonal recalibration that often goes unnoticed but can have a significant impact on our well-being. This transitional phase, known as perimenopause, can last anywhere from two to ten years leading up to menopause. During this time, physical and emotional changes can affect how you feel, and understanding perimenopause can be key to maintaining energy, mood, and comfort.

What Happens in Perimenopause?

Perimenopause brings a series of hormonal shifts that affect our menstrual cycle and overall health. One major shift is the decline in progesterone levels, which often happens faster than the decline in estrogen. This leads to a state of “unopposed estrogen”, where estrogen levels are high relative to progesterone. This hormonal imbalance can contribute to many of the symptoms you might experience:

• Low progesterone can increase anxiety, breast pain, heart palpitations, night sweats, migraines, and heavy periods.

• Excess estrogen or unopposed estrogen contributes to irritability, heavy bleeding, breast tenderness, and weight gain.

Recognising Unopposed Estrogen Symptoms

If these changes resonate with you, know that you’re not alone, and there are ways to manage these symptoms to feel more balanced. The imbalance created by unopposed estrogen during perimenopause can lead to a range of symptoms, such as:

• Heavier or longer periods due to a thicker uterine lining

• Shorter menstrual cycles (less than 25 days)

• Breast tenderness, swelling, or lumps

• Difficulty staying asleep, especially waking mid-sleep

• Increased menstrual cramps and migraines

• Premenstrual mood swings and anxiety

• Weight gain, particularly around the abdomen and thighs, without dietary changes

Supporting Your Hormonal Health Through Perimenopause

The good news is that many of these perimenopausal symptoms can be alleviated. Nutrition, movement, and stress management are foundational for keeping hormones in check, and our Go Diet Free program has been designed to support you in building these habits.

In addition to lifestyle changes, we use several evidence-based strategies to help balance hormones, including:

Nutritional Support for Estrogen Metabolism

Fibre, Magnesium, B vitamins, and DIM support estrogen breakdown. Low fibre intake can lead to reabsorption of estrogen and worsening symptoms

• Cruciferous vegetables help shift estrogen into more favourable pathways - broccoli, cauliflower, cabbage, Brussels sprouts

• Fibre is essential for eliminating estrogen via the gut - aim for 5-6 handfuls of veggies daily, and a serve of nuts or seeds

Protein for Hormone Balance

Protein supports hormone production, liver detoxification, and blood sugar stability, and helps reduce cravings, energy crashes, and overeating

• Aim for ~20-30g protein per meal

• General guide: ~1.2-1.6g per kg body weight per day (adjust for activity levels)

• Prioritise: eggs, fish, chicken, red meat, Greek yoghurt, legumes

Carbohydrates & Weight Management

Excess refined carbohydrates can drive insulin resistance and fat gain. Higher body fat = increased estrogen production

• Focus on quality over quantity - start at about ½ cup of carbohydrates per meal

• Reduce: sugar, processed snacks, refined carbs

• Prioritise: vegetables, berries, legumes, whole food carbs

Nervous System Support

Support GABA - the brain’s calming neurotransmitter, which can improve sleep, mood, and stress resilience

• Magnesium & B6 may reduce PMS, headaches, muscle tension, and hot flushes

• Taurine can further support calming and nervous system regulation

Histamine & Hormone Symptoms

High histamine may worsen migraines, breast tenderness or skin irritation. Estrogen and histamine can amplify each other. A low-histamine approach may help in some cases (individualised)

Liver Support (Key for Hormone Health)

The liver is responsible for breaking down and clearing estrogen

• Support it by:

  • Eating enough protein

  • Including bitter greens (rocket, kale, herbs)

  • Staying well hydrated

• Reduce “liver loaders”:

  • Alcohol

  • Excess sugar

  • Ultra-processed foods

Body-Identical Hormones

This may be helpful for some women with more significant symptoms. Progesterone support can improve sleep, mood, and cycle symptoms, but should be discussed with a practitioner and healthcare provider

Extra Support Is Here

Perimenopause may bring new challenges, but you’re not alone in navigating this phase. Recognising the role of these hormonal shifts can be empowering. With the right support, perimenopause can become a manageable and even transformative period.
