How it works

Science, not guesswork.

Developed to address your health from the inside, out

Developed by Nutritionist, Donna Aston, and her team of medical and health professionals, our evidence-based program has been built using a foundation of sound clinical data to identify and address dysfunction at its core.


This is what separates us from programs focussed solely on the tip of the iceberg – weighing less.


While the breadth of research and experience that underpins our programs is complex, it enables us to deliver accurate, simple-to-follow programs, designed to optimise health from the inside, out.

Frequently Asked Questions

I’m time-poor. Is there a lot of cooking and preparation required?

Your meals can be as simple or as complex as you wish. Our recipes are designed to assist you with preparation, variety and inspiration for meals and are not complicated to follow.

I have to cook for others in my household. Can this be done?

All recipes are commonly enjoyed by the entire family, whether or not they are on the program. We recommend you cook the basic meal and family members can add ‘extras’ if they wish.

How important is it that I exercise on this program?

VERY! I used to say that nutrition was 80 per cent of the fat loss equation, however, I now know it’s 50-50 exercise and nutrition. Contrary to popular belief, the exercise is not about burning calories. Regular exercise changes the way your metabolic system functions – increasing insulin sensitivity (your muscles have a bigger appetite to draw sugar from your blood) and regenerating mitochondria (the ‘engine’ within your cells). Basically the more muscle you have, the more metabolically-active tissue you have and the more fat you will burn, even at rest. Nutrition makes a great difference to improving half of your metabolic function, but exercise fulfils the other half. Consistency, intensity and frequency are imperative. Exercise is also important to improve overall strength and mobility.

Will I have enough energy to exercise?

It's a common misconception that we may curl up in the fetal position and feel lethargic and weak when we ‘diet’. On some programs, this may be the case, however, the program is structured precisely to create changes in the way your metabolism functions, so you will, in fact, have more energy to exercise. With the intermittent nature of the scheduling and specific timing of meals, you will experience (by around day 5) a boost in your metabolic rate and growth hormone output, giving you an almost euphoric feeling. Your blood sugar will be more stable than ever as your body switches over to burning stored body fat as its primary fuel source. The result – fat loss and endless energy!

Are the supplements important?

In a word – VERY! The supplement regime (selection and timing) has been customised for your specific needs. Each has a purpose, from helping you to manage blood sugar and cravings to building a healthier gut, enhancing your digestive health and improving your cholesterol profile (if required). If you do not take them as outlined in your program, you risk sub-standard results.

What happens after the 28-day program? How do I maintain my results?

Throughout the 28-day program, you will also be privy to an exclusive education process, personally designed by Donna Aston, to provide you with the knowledge and skills to maintain your results for a lifetime. Once you’ve completed the initial 28-day program, our support and guidance continues with your customised maintenance plan.

Following completion, you will have the option of registering for the AstonRX membership. This monthly or annual membership provides you with a customised LIFE meal plan, which you can follow to maintain and/or continue achieving results. This membership also provides ongoing access to your original 28 day plan, our private forums, a range of clinical supplements, recipes, blog posts, online fitness and, of course, our ongoing support.

If you haven’t quite reached your goal, or if you need another ‘boost’ to reach your next goal in months to come, members have the option to complete a program repeat at a heavily discounted price.
