When people think about nutrition for performance, they often focus on what they eat around training. Enough fuel to get through a session, tick the workout off, and move on with the day. In this blog, our Registered Dietitian Sophie explains how fuelling well isn’t just about workouts but, crucially, it’s about supporting consistency across your entire day.

"We see this often: people structure their nutrition around training, but still feel flat or overwhelmed for the rest of the day." Sophie Registered Dietitian at SPG

Training Isn’t the Only Place Under-Fuelling Shows Up

It’s common for people to structure their nutrition around their gym sessions. On the surface, that can look like things are “working.”

But what we often see is this:

Energy is just enough to get through training
The rest of the day feels flat, foggy, or overwhelming

If you’re under-fuelling, it won’t only show up in the gym. It shows up as:

Low energy at work
Feeling more irritable or snappier than usual
Struggling to focus
Having no patience left for anyone by the end of the day

This is especially common for people juggling work, parenting, training, and busy schedules.

Your Body Isn’t Lazy, It May Be Simply Conserving Energy

When you don’t eat enough to meet your daily demands, your body adapts.

As Sophie explains, the body can shift into a kind of conservation mode or “low power mode”:

Energy levels drop
Mood can dip
Focus and patience decline
Consistency becomes harder not just with exercise, but with day-to-day life

This isn’t your body failing you. It’s your body asking for more fuel.

Dietitian Assures - Fuelling Supports Consistency

At SPG, we care deeply about long-term progress, not short bursts of effort followed by burnout. Consistency is what drives results in training, recovery, and in work and life outside of the gym.

Fuelling well supports that consistency. When you meet your energy needs, training feels more repeatable, recovery improves, mood and focus stabilise, and you have more capacity for the rest of your day.

This is where working with a dietitian can make a meaningful difference, not through rigid meal plans, but through practical, individualised strategies that fit real life.

Fuel Your Workout - But More Importantly, Fuel Your Day

Yes, fuelling your training matters. But for most people, the bigger unlock is learning how to fuel the entire day, not just the hour you spend exercising.

At SPG, our dietetics support is designed to help clients:

Sustain energy beyond the gym
Feel better day to day
Build habits that support long-term consistency and progress

Because performance doesn’t stop when your workout ends. If you want support with fuelling in a way that actually fits your lifestyle, our dietitians are here to help.
