1. Find your own lane – don’t take on someone else’s nutrition or health identity.
2. Run trial and errors – don’t come to any overly firm conclusions.
3. Lean in – don’t do anything that isn’t sustainable – get more support if you need it.

Nicki Thompson has spent over 20 years working in health and fitness, with experience spanning personal training, group fitness coaching, health coaching, and gym management. Her journey began when she was first introduced to the gym in her early twenties, sparking a passion for fitness that never left her.

Despite outwardly appearing “in shape,” Nicki’s relationship with health was far from balanced. Behind the discipline, calorie tracking, and intense training, she was caught in a cycle of extreme restriction followed by secret bingeing, driven by control rather than self-care. No matter how much she knew about nutrition and fitness, lasting change felt out of reach.

Everything shifted when Nicki turned her focus to mindset, habit change, and the psychology of behaviour. She discovered that willpower is limited, and that real transformation comes from self-awareness rather than force.

Fasting became a pivotal tool in her own healing. Beyond the physical benefits, it offered clarity, calm, and the space to observe patterns without judgement. This reframing of fasting as a practice of awareness, not punishment, became central to her approach.

Nicki is now a certified Functional Nutrition Health Coach, Cognitive Behavioural Coach (CBT), Rational Emotive Behavioural Coach (REBT), and Goal Success Coach. She specialises in helping women step out of all-or-nothing cycles and build sustainable health grounded in self-trust, flexibility, and long-term progress.

1. Set a goal, decide what that is, what you want and what’s the bigger vision that you see for yourself.
2. Write down the actions that you would do when you have achieved that. Make a list of actions of what this version of you looks like.
3. Create affirmations based on points 1 & 2.
