What kind of results can I expect from Fast Start?

CSIRO research shows exceptional results for people following the Fast Start meal plan with shakes:

98% of members experienced weight loss
75% achieved clinically significant results (losing more than 5% of their body weight)
Average weight loss: 7.4% of body weight in the first 12 weeks

These outcomes not only support healthy weight loss, but can also help reduce risks associated with type 2 diabetes, heart disease, and stroke.

Can I continue using the shakes after the initial 3 weeks?

Yes — but it’s important to know that Fast Start shakes are designed to deliver a powerful weight loss boost during the first 3 weeks of your membership. This initial phase helps you lose weight quickly, control cravings, and build momentum for long-term success.

After the first 3 weeks, you’ll transition to the full CSIRO Total Wellbeing Diet meal plan, which reintroduces regular meals while maintaining structure and balance. However, you can still use the shakes as a flexible option to support your goals:

Replace breakfast or lunch for a quick, portion-controlled meal
Use shakes on busy days when you need a healthy, convenient choice
Maintain steady progress after your Fast Start phase
Support long-term weight management without calorie counting

The shakes are most effective during the Fast Start phase, but they remain a convenient and healthy part of your ongoing wellness routine.
