Louise Parker has been transforming clients’ lives for over 20 years. Whilst studying for her drama degree, she qualified as a personal trainer and spent the next decade training clients all across the world. An inspirational coach, Louise identified the importance of embedding lasting change at a behavioural level rather than only focusing on nutrition and exercise, laying the foundations for our method today.

Louise created her Method for anyone wanting to lose weight: busy mums, fitness fanatics and everyone in between. That includes everyone at The Parker Practice, because we’re all too familiar with fad diets and quick-fix solutions.

Louise knew how traditional weight-loss plans could quickly become emotional roller coasters, leaving you drained of energy and sapped of confidence. Which is why she’s always treated her clients not as hardcore gym bunnies, but as normal people with the same hang-ups and negative experiences we can all relate to. She recognised the typical struggles and frustrations, and from that came to the conclusion that the secret to losing weight is nurture not punishment.

Louise has published three Sunday Times Bestselling books and is regularly featured in the press. Louise is an ambassador of The Prince's Trust ‘Change a Girl’s Life’ initiative. She personally coaches a small number of clients each year; typically those with demanding lifestyles or exceptionally high-profiles.

Louise splits her time between the clinic in London and her home in Sussex, and has three daughters aged 13, 11 and 7.


We’re proud to be an Ambassador of The Prince’s Trust ‘Women Supporting Women’ group. The mission of Women Supporting Women is simple: to provide the right help to nurture, empower and inspire young women to build their own futures through employment, self-employment, education or training.
