Frequently asked questions

Are the recipes and meal plans family-friendly?
Yes! While the program itself is not suitable for people under the age of 18, the recipes and meals are definitely family friendly. All you need to do is adjust the shopping list to accommodate any family members also following the meal plan. You may want to also adjust the portion sizes and proportions for those with different nutritional needs.
Can I still enjoy my favourite foods and socialise while on this program?

Of course! We’ve tried to make our program as easy and sustainable as possible and that means factoring in those fun social occasions, as well as your favourite treats. We have a food group that specifically caters for this called Indulgences which covers this. You can learn more about those here.

I have specific dietary requirements (e.g. vegetarian, vegan, allergies, gluten-free). Is this program suitable for me?

We have a gluten-free meal plan that can be chosen during setup, but at this time we do not have a specific vegetarian or vegan meal plan. The online program can be adapted to this style of eating however, and we have a great Help Article on how to do that here.

If you suffer from food allergies, you can absolutely substitute out food that you can't eat for things that you can. This is the beauty of our food groups as all food can be swapped within the same group. For example, if you can't eat nuts, you can swap this for avocado in the healthy fats and oils category, or if you can't eat bananas, you can swap this ingredient for apples. However, please be aware that at this time you cannot choose a meal plan that eliminates foods you are allergic to.

Are the meal plans budget-friendly?

We've tried to make our meal plans as cost effective as possible, filling them with regular supermarket ingredients and using leftovers later in the week to avoid wastage.

We even recently released a new Simple meal plan that is designed to be our quickest, easiest and most budget-friendly plan yet. You'll find new recipes and many no-cook meals that use just a few shortcut ingredients to save you time. The result is quick meals that cost less but still taste great!

I have a medical condition, is this program suitable for me?

We’ve tailored our 12 Week Program for the top four health conditions that can be improved with weight loss. If you suffer from prediabetes or type 2 diabetes, high cholesterol, high blood pressure or joint pain, our Health Conditions Programs are for you!

What makes your program different from other diets?

So many things! First and foremost, we don't believe in eliminating any foods or food groups, or in counting calories. Instead, our 12 Week Program focuses on eating all foods in moderation to to ensure you get optimum nutrition from whole foods.

Second, our program is also created by Australia's national science agency, so you know the program you are receiving has been tried, tested and validated.

And finally, we offer you a refund of $199 if you adhere to the scientifically formulated criteria. What could be better than that?

What kind of results can I expect?

Results are as unique as each of our bodies as everyone has a different starting point – some of our members have lost five kg and reached their goal weight, while others have lost 100 kg to reach their goal weight. But you can be confident that if you follow our program, you will lose weight. Why? Because it has been proven time and time again by science.

As a guide, the average rate of weight loss is about half a kilogram a week (averaged over 12 weeks). This might not sound like a lot but achieving this each week will add up to big losses over time – and losses that you’ll be able to maintain!
