Why You Feel Different in Your 40s (and What to Do About It)

If you’ve hit your 40s and found yourself wondering “Why do I feel so different in my body?” you’re not alone.
Maybe your energy is unpredictable, you’re gaining weight in places you never used to, your mood swings feel more intense, or you just don’t feel like yourself anymore.

I know this territory well—both from my own health journey and from working with hundreds of women through The Body Code, nutritional therapy, and quantum frequency work.
When I entered my 40s, my thyroid, hormones, and mood were a total mess. I was exhausted, foggy, and living in a body that felt out of sync with the life I wanted.

The good news? You can feel vibrant, energised, and confident again.
This guide will walk you through what’s really happening in your body, why “just pushing harder” doesn’t work, and how to address your hormones, nervous system, and subconscious patterns in a way that works with your body—not against it.

Why Energy Changes After 40

Our bodies are designed to shift with every decade, but the changes in our 40s can feel particularly dramatic. That’s because this is the stage where hormonal transitions, accumulated stress, and lifestyle patterns start to intersect.

Some of the main drivers include:

  • Perimenopause & menopause: Estrogen, progesterone, and testosterone begin to fluctuate, impacting mood, sleep, muscle tone, and metabolism.

  • Thyroid changes: Even subtle shifts in thyroid hormones can cause fatigue, weight changes, and brain fog.

  • Slower metabolism: Loss of muscle mass naturally slows calorie burn and impacts insulin sensitivity.

  • Stress load: Years of “running on adrenaline” catch up, leading to adrenal fatigue or insufficiency—not the place you want to be entering perimenopause.

These changes aren’t just about “getting older.” They’re your body’s way of saying: It’s time to be supported differently.

The Role of Hormones in Energy, Mood & Weight

Hormones are your body’s chemical messengers. When they’re balanced, everything flows—you have steady energy, a stable mood, and your metabolism works as it should. When they’re out of balance, the ripple effects touch every system.

Key players for women over 40:

  • Thyroid hormones → regulate metabolism, energy production, and mood.

  • Cortisol (adrenal health) → manages stress response; when too high or too low, it disrupts sleep, weight, and mental clarity.

  • Estrogen & progesterone → affect mood stability, muscle tone, and fat distribution.

  • Insulin (pancreas function) → impacts belly fat, energy crashes, and sugar cravings. Poor insulin sensitivity is one of the main culprits behind stubborn midsection weight.

In my own healing journey, I found that once I began clearing subconscious patterns around being deserving and self-love, I was naturally more motivated to nourish my body well. I prioritised protein to maintain muscle mass, support hormone production, and stabilise blood sugar—something I now see as essential for women over 40.

I’ve also seen incredible changes in clients when we combine nervous system realignment with tailored nutritional support.
One woman in her 50s came to me stressed, depleted, and unsure what to try next. Using The Body Code, we reset her nervous system, then muscle tested to see what her body truly needed. The answer? Simple trace minerals, electrolytes, and a few gentle diet changes. She started feeling better almost immediately—calmer, more energised, and more balanced—without needing to return to HRT.

This is the power of working with the body’s exact needs, instead of throwing generic solutions at it.

All of these changes can also have a huge impact on your gut health. As we age, the make-up of our gut microbiome begins to change as well, which can lead to digestive trouble such a bloating and discomfort.

How Stress & the Nervous System Play In

If your hormones are the messengers of your body, your nervous system is the switchboard that controls how those messages are sent and received.
When the nervous system is balanced, it communicates clearly with your hormonal systems. When it’s dysregulated—stuck in fight, flight, or freeze—it throws those messages into chaos.

Stress Chemistry vs. Hormone Harmony

Chronic stress keeps cortisol high for long periods of time. Over time, your adrenal glands can shift from overproducing cortisol to barely producing it at all—a state often called adrenal insufficiency.
For women in their 40s, this is not the state you want to enter perimenopause in. Without resilient adrenals, every hormonal change feels more intense: mood swings are sharper, sleep is harder to maintain, and energy drops feel like brick walls.

And here’s the kicker:

  • High cortisol disrupts progesterone production, contributing to mood swings, anxiety, and heavier periods.

  • It also increases insulin resistance, making belly fat harder to lose and afternoon energy crashes more common.

  • On top of that, constant stress diverts resources away from your thyroid, further lowering energy and slowing metabolism.

Why Nervous System Regulation Comes First

You can eat the perfect diet and take the best supplements, but if your body is in survival mode, it will always prioritise safety over repair.
That’s why in my work, nervous system realignment is the first step.

With The Body Code, I can pinpoint and release the trapped emotions, old patterns, and imbalances that are keeping your nervous system on high alert.
Once your body feels safe again, your hormones have a chance to stabilise, your digestion works better, and you can absorb and use the nutrients you’re giving yourself.

The Confidence-Energy Cycle

When stress is calmed and hormones begin to rebalance, everything starts to feed into a positive cycle:

  1. Energy rises → you feel more motivated to move your body.

  2. Movement builds strength → muscle helps regulate insulin and burn more energy at rest.

  3. Better insulin sensitivity → easier fat loss, especially around the belly.

  4. Improved body composition → confidence grows, which feeds back into better habits.

This is how midlife vitality is built—not through crash diets or punishing exercise, but by aligning your nervous system, hormones, and subconscious patterns so your body can thrive.

The Subconscious & Emotional Connection

Hormones don’t just respond to physical changes—they respond to your emotional state and the beliefs running quietly in the background.
If you’ve ever noticed that stress, grief, or anxiety throws your cycle, appetite, or sleep out of balance, you’ve felt this connection firsthand.

The Invisible Patterns That Keep You Stuck

From childhood through adulthood, your subconscious mind collects beliefs about who you are, what’s possible for you, and how safe the world is.
Some of these are supportive. Others—often formed in moments of fear, rejection, or stress—can quietly limit you for decades.

For women over 40, I see a few patterns come up again and again:

  • “I don’t deserve to prioritise myself.”

  • “This is just what happens when you get older.”

  • “I’ll never feel like I used to.”

  • “If I slow down, everything will fall apart.”

These beliefs don’t just affect your mood—they shape your physiology.
When you feel undeserving or unsafe, your body is more likely to stay in stress mode. Cortisol stays high, progesterone drops, thyroid slows, and insulin resistance increases.

My Own Turning Point

One of the most powerful shifts in my own healing came when I uncovered what I call an “allergy to being deserving.”
On some deep level, my subconscious had decided it wasn’t safe for me to fully receive the life and health I wanted. This was driving subtle self-sabotage—skipping meals, staying up too late, ignoring my body’s cues.

Through The Body Code, I was able to identify and release this pattern. And something unexpected happened: I wanted to nourish myself better. I started eating more protein, supporting my blood sugar, and naturally moving my body—not because I was forcing myself, but because I finally felt I was worth caring for.

Emotional Healing as a Hormone Reset

When we release these subconscious blocks and create a sense of safety, your nervous system calms, cortisol drops, and your body becomes more responsive to positive changes.
Suddenly, diet changes stick. Movement feels enjoyable. Your energy rises, which feeds back into confidence—and the cycle of health builds momentum.

This is why in my work, emotional healing isn’t separate from hormone health—it’s the gateway to it.

My Journey Back to Energy

When I hit my 40s, I was running on fumes.
My thyroid, hormones, and mood were a complete mess. I had been diagnosed with clinical depression, and despite knowing a lot about nutrition and health, I couldn’t seem to pull myself out of the exhaustion and overwhelm.

I tried to push through, but my body wasn’t having it. Every crash diet or burst of exercise left me more depleted. I realised I couldn’t “out-discipline” my way to feeling better — I had to change my approach.

That’s when I began working on myself using The Body Code and other tools to realign my nervous system, reset my adrenals and endocrine system, and clear the subconscious programs that were quietly running the show.
One of the most powerful shifts came when I released that “allergy to being deserving.” Without that weight, I naturally started eating in a way that supported my health—more protein for hormone production and muscle maintenance, stabilising my blood sugar, and nourishing myself like I mattered.

As my energy rose, my motivation returned. I started moving my body more, not out of guilt or pressure, but because I wanted to. That positive cycle—more energy → more movement → better body composition → higher confidence—changed everything.

A Client’s Story

One woman in her 50s came to me feeling constantly stressed, fatigued, and frustrated with her hormones. She didn’t want to go back on HRT, but didn’t know how to feel better without it.

We began by realigning her nervous system using The Body Code, helping her body shift out of chronic stress mode. Then I muscle tested to see what her body needed nutritionally. The answer was surprisingly simple: trace minerals, electrolytes, and a few gentle dietary changes.

Within days, she felt calmer, more energised, and more balanced. Her sleep improved, her mood lifted, and she began to feel like herself again—without needing to add more medication. Sometimes, the most effective changes are the ones that are precisely matched to what your body is actually asking for.

Both my own experience and my clients’ results have shown me the same truth: when you work with your body—physically, emotionally, and energetically—you can feel vibrant, strong, and confident at any age.

Holistic Steps to Reclaim Energy After 40

Reclaiming your energy, balancing your hormones, and feeling confident in your body after 40 isn’t about doing more.
It’s about doing the right things — in the right order — so your body can work with you instead of against you.

Here’s the framework I use with my clients:

1. Support Your Nervous System First

Your body can’t heal or balance hormones while it’s in survival mode.
Before we change diet or exercise, I help you realign your nervous system using The Body Code to release trapped emotions, old stress patterns, and subconscious programs that keep cortisol high.

At home: Try daily breathwork or gentle grounding techniques to signal safety to your body. Even 5 minutes can make a difference.

2. Balance Blood Sugar to Reset Your Pancreas

Stable blood sugar is essential for reducing belly fat, improving mood, and restoring energy.
That means eating in a way that supports insulin sensitivity — the opposite of the “crash and crave” cycle that many women over 40 find themselves in.

Key tips:

  • Prioritise protein at each meal to support muscle, hormones, and satiety.

  • Pair carbs with protein or healthy fats to slow glucose spikes.

  • Avoid skipping meals if it leads to energy crashes and sugar cravings.

When I muscle test for clients, pancreas and insulin imbalances are incredibly common—and often overlooked. Addressing them early changes everything.

3. Nourish Your Body with Targeted Support

Your body heals faster when it has the building blocks it needs.
I work with both nutrient frequencies (installing the energetic blueprint of vitamins, minerals, amino acids, and adaptogens) and, if needed, high-potency practitioner-only supplements to quickly correct deficiencies.

This can mean simple, powerful additions — like trace minerals and electrolytes — that improve hydration, energy, and hormonal function almost immediately.

4. Rebuild Strength & Energy Reserves

When you start feeling better, movement becomes enjoyable again.
Gentle strength training, resistance bands, or even bodyweight exercises help maintain muscle, which is essential for a healthy metabolism after 40.
The more muscle you keep, the better your insulin sensitivity, energy levels, and confidence.

5. Install Supportive Truths & Quantum Frequencies

Once the body is out of stress mode, I install supportive truths into the subconscious—statements like “It’s safe for me to feel good now” or “I am worthy of a vibrant life”.
I also install quantum frequencies for hormonal balance, energy production, and overall vitality so your cells are literally resonating with health.

6. Protect Your Adrenals for Perimenopause & Beyond

Healthy adrenals mean you can transition through perimenopause without the dramatic energy crashes, mood swings, and sleep issues many women experience.
By addressing adrenal function now—physically and energetically—you set yourself up for a smoother, more vibrant next chapter.

💡 Remember: You don’t have to overhaul your life overnight. You just have to give your body the right signals and support.
When physical, emotional, and energetic systems are aligned, your body naturally finds its way back to balance.

Part of reclaiming your energy after 40 can mean easing the monthly rollercoaster of PMS or PMDD. The Body Code can help by pinpointing the emotional, energetic, and physiological imbalances driving your symptoms—so you can feel more balanced all month long. You can read more in my post on How The Body Code Can Help with PMS and PMDD.
