My passion is helping people reach goals they have struggled to achieve. While weight loss and body composition are the most active part of my practice, I also work with clients diagnosed with conditions such as osteoporosis and sarcopenia.

“Tired, bloated, weight gain, just not myself” – these are the most common complaints I hear from women navigating midlife. If this sounds familiar, the answer really isn’t a new fad diet or adding more stress with harder workouts. An important change you can make is simply adjusting what’s on your plate.

As our hormones shift, our nutritional needs change dramatically. What worked in your 20s and 30s won’t necessarily deliver the nutrition and results your body needs now. It’s time to shift your focus to nourishment, not restriction, to live better.

To build a stronger, more energized you in perimenopause and beyond, there are four key nutrients to focus on: protein, fats, carbohydrates, and fibre. Getting the right balance of these key players is what’s most important!

1. Protein: Your strength framework

Think of protein as the building blocks for your muscles and bones – the framework that anchors your strength. Protein is vital for longevity, functional strength, and a healthy metabolism.

Builds and preserves muscle

You know that strength training is your best weapon against age-related muscle loss. But without enough protein, you simply won’t get the maximum benefit from those squats and deadlifts!

Supports bones and joints

Strong muscles translate into better bone density, speed up recovery, and keep your joint tissues strong and supple.

Boosts stable energy

Protein stabilizes your blood sugar, keeps your metabolism fired up, and helps you crush those frustrating mid-afternoon energy slumps.

Suggestion

Aim for at least a palm-sized serving of protein at every single meal (e.g., turkey, lean beef, fish, cottage cheese, edamame beans, chickpeas, or a quality protein powder). For a precise target, aim for 1.2–1.6 grams of protein per kg of body weight over the day.

2. Fats: Essential hormone and brain support

Often fat is seen as bad, but the right fats are vital for everything from hormone production to a healthy, focused brain.

The hormone builders

Key hormones like oestrogen and progesterone rely on fat for their production. As your levels fluctuate, healthy fats help your body regulate and support the entire endocrine system.

Reduce inflammation

Omega-3s (found in oily fish, flax, and walnuts) are powerful anti-inflammatories that support mood, memory, and focus – essential for brain health in midlife.

Aids absorption

Vitamins A, D, E, and K are fat-soluble. Without healthy fats in your meal, you literally can’t absorb these vital vitamins!

Suggestion

Add a thumb-sized portion of healthy fats to your meals: olive oil, avocado, nuts, seeds, or a serving of oily fish.

3. Carbs: Fuel, not the enemy

Carbohydrates are your body’s preferred energy source, the fuel that powers your workouts and your brain.

Fuel your workouts

If you are doing strength or cardio sessions, you need carbs to replenish your energy stores. They also help produce serotonin, your “feel-good” hormone.

Stabilize mood

Skipping the right carbs can lead to blood sugar crashes, brain fog, and irritability. Consistent energy keeps your mood stable.

The type matters

Always focus on complex carbohydrates – whole grains, beans, root vegetables, and fruit – over highly processed options.

Suggestion

Include a fist-sized serving of complex carbs with your meals: quinoa, brown rice, oats, legumes, or sweet potato.

4. Fibre: The gut health powerhouse

Fibre impacts everything from digestion and gut health to energy and hormone clearance.

Supports gut health

A diverse, fibre-rich diet feeds your gut microbiome – a system linked to your immunity, mood, and hormone regulation.

Manages blood sugar

Fibre slows sugar absorption, helping you feel fuller for longer and stabilizing your energy.

Reduces bloating

It keeps your digestive system moving, which is crucial as digestion can become sluggish with changing hormone levels.

Suggestion

Aim for 25-30g of fibre a day. Load up on all kinds of vegetables, berries, legumes, seeds, and whole grains.

Bring it all together

Stop overthinking! Use this simple framework to build every meal and ensure you’re supporting your strength and energy goals:

Nutrient

EXAMPLE

Fueling tips to start today

  1. Upgrade breakfast: Swap simple toast or cereal for more protein e.g. eggs, cottage cheese.
  2. Carry a water bottle: Easier to keep hydrated
  3. Keep moving: Strength training and walking actively aid digestion and metabolism.

Not every meal will be ideal. Focus on the pattern of consistency over time. Your body is resilient – just keep aiming for the right balance!
