We are two sisters who are passionate about helping women with health, wellness, fitness, and overall life balance.

We developed Slim Mama Co. in 2018 because we have a passion for helping others, and we wanted to develop a platform to share our knowledge with as many women as possible!

We both bring unique backgrounds and experiences to Slim Mama Co. Nikki is a Solo Mama who has worked in the fitness industry for many years, including owning her own gym. She lost 20kg postpartum after having her gorgeous daughter Luna (who you will see modelling for us on our socials).

Kristy brings her expertise in nutrition and fitness to Slim Mama Co. In 2018, she graduated from the University of Wollongong with a Bachelor of Public Health (Health Promotion). She finished with a distinction average and was in the top 5% of her cohort. In addition to her academic studies, Kristy has worked in the fitness and weight-loss industry for 11 years as both a weight loss consultant and a personal trainer.


The Slim Mama Shake was developed because we wanted to design a meal replacement shake that will support you with your health and weight loss objectives and help you get your health on track - no matter how busy your day is!

We are often either too busy or too tired to have a nutritious breakfast - do you find yourself just grabbing something easy, quick, and full of calories instead? This habit not only impacts your weight loss goals and your overall health and well being, it also impacts your food mind set for the day. Start the day by making a good food choice.

The Slim Mama Shake is nutritious - and it tastes amazing too! It has a smooth and creamy texture, with absolutely no after-taste. Our shake is so delicious that you will look forward to having it each day.


Here at Slim Mama Co, we understand how hard it can be to find time to hit the gym and prepare meals while looking after yourself and your family. We also understand that you might not have the time or the brain space to stick to a crazy strict diet. This is why we are firm believers in the 80/20 rule - 80% health foods and 20% treat foods. The proof is in the pudding... and we love pudding! Let us help you get educated, find balance, get healthy and lose that unwanted weight without feeling like you’re only allowed to eat carrot sticks.

Our vision is to help you become the best version of yourself by helping you gain confidence, and love the skin you’re in!
