Practical nutrition & health advice for busy people (and families) on the go.

As a dedicated health coach with extensive experience, I specialise in partnering with individuals, corporate organisations and sports teams to foster sustainable, positive changes in habits and lifestyles for optimum health and performance As a qualified nutritionist and fitness coach, I am passionate about improving clients health, fitness & nutrition. I am also a busy mother of two young children and understand fully the daily challenge of making healthy food choices for our families given the time pressure we all experience in juggling daily life.

In cognitive behavioural therapy, we use tools like response cards to help clients talk back to sabotaging thoughts. Clients often work incredibly hard to build healthier habits around nutrition, movement and self-care and as a result they feel and see real improvements in their health and wellbeing. But long-term change also means recognising that old patterns can resurface under pressure. Knowing your triggers — and having a clear response to them - is key. This is how sustainable change is built: by addressing the thoughts that try to pull us off track, rather than ignoring them.

One of my clients finished my 10-week health programme this morning with fantastic results. Together, we identified that work stress can be a trigger for neglecting her self-care, nutrition and fitness. With this awareness, she is now prioritising her health alongside all the other “balls she is juggling.” She feels strong, confident and in control, having lost 3 stone and significantly reduced her health risks.

In our final session, we focused on identifying potential future triggers and creating a personalised response card — a clear, powerful reminder of how she chooses to respond when challenges arise, reinforcing calm, consistency and self-respect over old habits.

“My health is not negotiable. Taking time to eat well, move my body and reset my mind is not selfish - it is what allows me to cope, perform and feel like myself. I choose calm over chaos, consistency over burnout and self-respect over short-term pressure. I am in control and I protect the habits that make me feel strong, confident and well.”

I work with clients to build lasting, sustainable health habits and the mindset to protect them. If you’d like to learn more about my health coaching programmes, you’re welcome to contact me.

For many of us, making time for our health can feel like a struggle when there are so many other demands on our lives.
 My clients often tell me they know what to do, but need accountability, support and guidance to help them follow through and stay consistent — and that’s where I come in!

My job as a Health Coach is to work with you on sustainable behaviour change and mindset using practical CBT-informed tools, so you’re not relying on motivation alone.

The aim is long-term progress, realistic routines and habits that fit your life.

I’m now taking on a limited number of new clients starting in February. Full details are available via www.alvaosullivan.com

It’s hard to believe it’s almost six years since I started running my live, interactive Strength Pilates class every Thursday evening (7–8pm).

Each week, a fantastic group of busy women join me to work on building muscle, bone strength, mobility and overall resilience. No two classes are ever the same—I change things up weekly to keep it engaging, progressive and challenging.

Every movement is layered with options from beginner to advanced, so everyone can work at the right level for their body. What matters most to me is quality: strong form, precise movement, good flow and using the breath to support and control each exercise.

Because it’s live and interactive, I’m there to guide, support and give feedback throughout—so you’re not just following along, you’re progressing with intention.

Every class is recorded, and all sessions are available on YouTube, so you can revisit classes anytime or use them for extra practice when it suits your schedule.

If you’re busy, want to get stronger and value expert guidance from the comfort of your own home, you might be a perfect fit.

Why We Emotionally Eat After a Setback and How to Break the Cycle

You’re eating well, training consistently, feeling strong… and then life happens.

Routine slips. Stress rises.
And suddenly food becomes comfort, distraction or a way to cope.

When structure disappears, your self care is usually the first thing to drop off the list. Your meals become rushed. Your wellbeing gets sidelined and emotional eating fills the gap.

That’s when all-or-nothing thinking shows up:
“I’ve already messed up, so what’s the point”

Long-term health and weight management isn’t about stricter rules. It’s about learning how to prioritise yourself, even when life is busy.

That’s exactly what my 10-Week Health Coaching Programme is designed to do.

This isn’t a diet or a reset, It’s a short, supportive programme where we use cognitive behavioural therapy (CBT) based tools to:

• identify emotional eating triggers
• break unhelpful thought patterns
• rebuild a healthy structured fueling routine without restriction
• prioritise your health and self-care without guilt
• create long term habits that fit your life

Taking care of your health isn’t selfish… it’s the foundation that allows everything else to function better.

👉full details of the programme are on my website www.alvaosullivan.com or DM me for info 😊

Some days my body enjoys moving fast and furious — a functional training workout or a sweaty cardio class.
 Other days it wants to lift heavy and feel powerful
 And many days… it just wants to slow down — stretch, strengthen, breathe and reset with Pilates

If you find yourself skipping workouts because you “don’t have the energy” this is for you

Midlife training isn’t about forcing one style of exercise
 It’s about listening — and choosing the movement that supports you that day

The most important thing is making time for yourself
 And when that habit becomes consistent, we feel stronger — physically and mentally

Movement is powerful. 💪✨

Save this for days motivation is low 😊

The quality of the produce makes this plate truly delicious (and nutritious) Bollo Privilege oranges 😋 and creamy Fage 5% yogurt (with a sprinkle of my own roasted oats/seeds and coconut) and it’s still cheaper than a scone or croissant 🥐 !

A Simple Winter Habit to Support Immunity

As the days get shorter and winter settles in, we tend to think about immunity only when sniffles start appearing. But supporting immune health is really about what you do consistently, not reactively. One simple, food-first habit that’s especially useful in the winter months is adding fermented foods and a variety of plants to your diet.

What are fermented foods?

Fermentation is a natural process where bacteria or yeasts break down sugars in food. This process creates beneficial compounds and, in many cases, live microorganisms that can support gut health.
Common fermented foods include:
* Yogurt and kefir (with live cultures)
* Sauerkraut and kimchi
* Miso and tempeh
* Kombucha
* Fermented vegetables like pickles (naturally fermented, not vinegar-based)

Why gut health matters for immunity
Around 70% of the immune system is associated with the gut. The gut isn’t just about digestion — it’s a major communication hub between your immune system, metabolism and even mood.

A healthy, diverse gut microbiome helps:
* Train immune cells to respond appropriately
* Act as a barrier against harmful pathogens
* Regulate inflammation in the body

Fermented foods support gut bacteria diversity and also complement immune-supportive nutrients like vitamin D, zinc, protein and fibre — by helping your body use those nutrients more effectively by supporting digestion and absorption. They may also help regulate inflammation as certain fermented foods are associated with improved gut barrier function and reduced inflammatory markers, which is particularly helpful during cold and flu season.

How much do you need?

A good starting point:

* 1 small serving daily or most days
* Rotate types rather than sticking to just one
* Pair with fibre-rich foods (vegetables, whole grains, legumes) to feed the beneficial bacteria

If you have digestive issues, start slowly and see how your body responds.
