Rupali is a holistic health practitioner who knows there are no magic pills or 'one-size-fits-all' solutions in healthcare. A registered New Zealand pharmacist, she runs her virtual clinic, Pause.Breathe.Live, focusing on Functional Nutritional Therapy. Specializing in gut health, she offers functional testing to guide clients toward true healing.
It’s almost become a cultural norm: middle-aged men with growing bellies, low energy, and yes, even a little breast tissue. Often dismissed as a "dad bod" or “just aging”, these changes are actually signs that the body is under stress and adapting in ways we might not realise. As a functional health practitioner, I don’t just look at weight or hormones in isolation, I look at what’s burdening the body and where the imbalance really began.
It’s not just about aging – It’s about bodily burden
As men age, testosterone levels naturally decline. This decrease can lead to symptoms such as reduced muscle mass, decreased libido and increased fatigue. But the speed and severity of these changes vary greatly depending on lifestyle, stress, nutrition, and metabolic health. Hormonal shifts in men aren’t just genetic destiny- they're often the result of chronic stress, ongoing blood sugar imbalances, disrupted sleep, poor diet, alcohol or environmental exposures- things we can become aware of and reduce.
In functional nutrition, we always ask: What is contributing to the body’s dysfunction or overload?
How body fat affects hormones
Fat (adipose tissue) isn’t just passive storage, it’s metabolically active. In fact, excess abdominal fat in men can directly influence hormonal balance. Fat tissue contains an enzyme called aromatase, which converts testosterone into estrogen- yes, in men too. ₁ Over time, this can create a hormonal loop that increases fat storage, reduces libido and leads to symptoms like fatigue or gynecomastia (enlarged breast tissue). ₁
So the more weight you carry around your middle, the more hormonal imbalance you might experience and the harder it becomes to lose weight. It’s a feedback loop. This imbalance contributes to symptoms often associated with andropause, including:
Decreased libido
Erectile dysfunction
Fatigue
Mood swings
Loss of muscle mass
Increased abdominal fat ₂ ₃
These symptoms don’t just impact physical health- they can influence confidence, relationships, and overall quality of life.
Blood sugar & stress: The underrated duo
Most men aren’t thinking about blood sugar unless they’ve been told they have diabetes. But even without that diagnosis, riding the blood sugar rollercoaster- skipping meals, relying on caffeine, snacking late at night or eating lots of refined carbs places the body under constant stress.
This pattern triggers the release of cortisol, the stress hormone. Chronically elevated cortisol levels can suppress testosterone production, ₂ encourage fat to accumulate around the belly, ₃ and lead to insulin resistance. All of this puts more strain on your hormonal system.
If this becomes your everyday norm, your body prioritises survival over vitality. That’s when you feel sluggish, struggle to recover from workouts, lose motivation, or notice changes in mood and libido.
The big picture: it’s about foundations
In functional nutrition, we don’t chase symptoms. We go back to the basics and ask: what is the body trying to tell us? Then we reduce the burden so it can come back into balance.
This includes:
Balancing blood sugar - by eating nutrient-dense meals, regulating meal timing and reducing refined sugars
Nourishing the body - with quality proteins, healthy fats and a variety of whole foods
Building stress resilience - supporting the nervous system and giving the body the safety it needs to heal
Improving digestive health - because proper absorption of nutrients like zinc, magnesium, and B vitamins is key for testosterone and energy production
When done consistently, these foundations can shift how your body feels and functions, naturally.
This isn’t about quick fixes
There’s no magic supplement or workout that can override a chronically burdened system. Functional health is about understanding the deeper story behind your symptoms- your stress load, your environment, your food, your sleep and working with your body, not against it.
If you’ve been told “this is just part of aging”, I want you to know that’s not the whole story. Your body isn’t failing, it’s adapting. It’s time we listened.
