Level 4 Nutrition & Performance: how it’s helped my clients
Completing my Level 4 PT qualification in nutrition has given me a far deeper understanding of how to support fat loss, performance, and long-term health. Most importantly, it’s helped me coach real people with real preferences and habits.
Prior to completing my Level 4 qualification, I often found myself tiptoeing around nutrition when clients asked about it. I was conscious of my scope of practice and cautious about offering advice without the right qualifications behind it.
However, there is no getting around the fact that nutrition is the most fundamental pillar when it comes to seeing real, sustainable results. Training matters but without addressing nutrition head on, progress will always be limited.
As more clients came to me with goals around body fat loss, and as my own passion for nutrition continued to grow, I decided to invest in my Level 4 qualification in Weight Management and Sports Performance.
Since completing the course, my confidence in discussing nutrition has increased a lot. I’m now able to provide clear, evidence-based guidance on food choices and lifestyle behaviours, alongside scientifically backed recommendations around meal timing and macronutrients. This allows me to face nutrition head on and deliver advice that is practical and firmly within scope. Below are three client examples that show how small, informed changes can make a big difference.
Robert
Robert trains with me three times a week and wanted to reduce body fat in prep for a trip away. Rather than immediately prescribing rules or restrictions, we started with awareness. I asked Robert to log his food using an app we could both access. The initial goal was simply to observe what and how he was eating.
What became clear quite quickly was that we didn’t need drastic changes. By slightly reducing portion sizes and making more intentional protein choices, Robert was able to sit in a calorie deficit without cutting out foods he enjoyed.
One of the biggest wins was Robert’s consistency. Even on indulgent days, he tracked everything. This allowed us to shift perspective away from daily “good” or “bad” eating and instead look at energy balance across the week. A higher-calorie day could be followed by a few more focused days, without guilt or panic.
Robert left for his trip to Australia 2.5kg lighter and, in his words, the leanest he’d been in years.
David
David wanted to lose body fat ahead of his 70th birthday celebration. He’s a keen runner and strength trains twice a week.
When we reviewed his usual eating habits, it became clear that much of the excess energy was coming from small, easy-to-overlook additions. Things like jars of marinade used regularly were quietly pushing calories up.
By tidying up these areas, David was able to create a modest calorie deficit with very little disruption to his routine. Over Christmas he still enjoyed a few mince pies, but again, awareness changed everything. He understood his energy balance and how to get back on track, rather than feeling he’d “ruined” everything. He also noticed how much easier it was to stay on track with his nutrition if he had slept well and avoided alcohol.
Zoe
Zoe has trained with me twice a week for two years and has built excellent strength and muscle tone. With a wedding coming up in May, she wanted to feel confident in her outfit on her friend’s special day.
Once we began tracking her intake, what stood out immediately was how little she was actually eating. This was likely contributing to low energy and slower muscle gain.
Her protein intake was sometimes as low as 40–50 g per day. We increased this to around 90–100 g, alongside increasing her daily steps. I also encouraged bigger, more balanced breakfasts to stabilise her energy and reduce afternoon snacking. I suggested she stopped grazing throughout the day and ensured she was well fed but still in a small deficit all day.
Another key change was carbohydrate timing. When I noticed how low her carb intake on training days, I prompted her to include simple carbs, such as fruit, before training sessions. This helped her lift with more intent and get more out of each session.
The Bigger Picture
A lot of the time, I’m not telling clients to eat less. I’m telling them to eat more: more protein, more fibre, and often more carbohydrates.
When people have limited nutrition experience and want fat loss, it’s common to assume that crash dieting or extreme restriction is required. In reality, if the goal is to change body composition, we want to preserve lean mass, build skeletal muscle, and lose body fat.
That is achieved through a small, sustainable calorie deficit, consistency over time, and increased daily movement (NEAT: non-exercise activity thermogenesis), alongside structured resistance training.
To build a strong, robust, athletic physique, we must fuel with intention and confidence, not fear. It takes whole, balanced and real food to build a physique we are proud of!
Robert’s Testimonial
“I’ve been training with Martha for two and a half years. She always makes an effort to change goals and keep my program fresh and we decided to put more focus on my nutrition.
I thought I was eating a fairly healthy diet, but Martha encouraged me to log all my calories using My Fitness Pal and by adding her as a friend in the app, she gets to see what I eat too.
The downside to this is the occasional stern look from Martha when I scoff a Cadbury Creme Egg or give in to that late night McNugget craving. I’m only human after all…
The upside to tracking is the ability to see exactly where your excess calories come from and make adjustments.
I was shocked to learn that a few less cashews on breakfast porridge can reduce my daily calorie intake by 10%! One of my regular meals was a rack of pork ribs, that I didn’t realise was a whopping 1300 calories. Now I eat 2/3rds of the rack and use the leftovers for a protein rich lunch the next day.
None of the changes I’ve made have involved suffering or deprivation. But by targeting the worst elements of my diet and making small tweaks, I’ve managed to consistently lose 1kg per month”.
