ONE - Human Performance Institute A new result-driven approach to health and fitness

25/10/2026

Sandra, one of our head trainers and managers, explains some signs your body shows when that fat
loss is finally happening.

Here’s what you should be aware of:

1. You’re peeing more than usual. Just your body regulating fluids and glycogen differently as habits change.

2. You feel colder, especially hands and feet. Less stored insulation, more efficient energy use.

3. Your sweat smells different. Not worse. Just different. A sign your body is relying more on fat as fuel instead of quick carbs.

4. Sudden energy spikes. You’re calm… then suddenly productive. That’s your metabolism becoming more stable.

5. Your face changes first. Jawline, cheekbones, eyes looking sharper. Most people notice it before the scale ever moves.

6. Clothes fit… oddly/differently. Tighter where muscle is building. Looser where fat is leaving.

7. Sleep improves. Deeper nights, fewer wake-ups. Hormones start cooperating when stress and blood sugar stabilise.

8. Your mood evens out. Fat loss isn’t just physical. Clients often start feeling calmer, clearer, less reactive.

9. More definition without trying. Veins, lines, muscle shape; now there’s less covering the work you’re already doing.

10. Cravings quiet down. Craves may not go away forever, but they become more manageable. Hunger hormones begin to reset when consistency replaces guesswork.

Sandra always says this: “Fat loss isn’t dramatic when it’s done right. It’s subtle. Predictable. And
surprisingly boring, in the best way.”

Same coach. Every session.

He knows your training history, your work week, and what you lifted last Tuesday, and how to get you results that last.

That’s the difference between a trainer and a coach who sees the whole picture.

DM “STRONGER” and we will pair you up with the right coach for you.

Seb’s mornings, Monday to Friday:

DRINK: 500ml water + electrolytes. Refuel the body after the night.

DO: 15–30 min walk or cycle. Move, get fresh air, get some sunlight.

EAT: A balanced meal. Protein, carbs, fats, fibre. Everything the body needs to perform.

Weekends shift the order:

Drink. Eat. Train. Eat again.

Nothing complicated. Just the basics, done every day.

What’s the first thing you do when you wake up?

Don’t start with shame start with structure.

The comeback starts with a plan that meets you where you are. You don’t have to wait for a big moment to start. You don’t have to wait for the New Year, or after your birthday, or when you finish a big project at work.

Life will always keep on giving you a reason to doubt if you should start. Start where you are now and your future self will thank you.

At ONE you’ll find structure that will hold your real life. Even in the most messy weeks.

Come and see what we are all about (go check out our last slide).

January to May. Two sessions a week.

January: 69.4 kg, 11.14% body fat.
May: 72.3 kg, 9.29% body fat.

Joey gained +3.9 kg of lean mass. He got heavier and leaner at the same time, that doesn’t happen by accident. It happens by design.

Around 35 sessions. Each one built on the last. Load tracked, progress reviewed constantly and a plan that was adjusted.

No extra training days, no extreme diet and no starting over. Four months of structure, written in numbers.

Want to know what your numbers say? Comment “ASSESS” and we’ll book your free athlete assessment only valid this month.

NOT JUST. ANOTHER ONE.
