Get a kickstart with Fast Start

Our Fast Start meal plan integrates meal replacement shakes with recipes designed specifically to work with them. Together, meal plan and meal replacement shakes form a simple, structured approach that helps you take control of your weight loss journey from day one. Whether you’re looking for convenience, craving control, or a motivating kickstart, the Fast Start meal plans offers an easier way to see real results.

Developed with support from the scientists at CSIRO, this unique combination delivers proven success. In a comprehensive study, 98% of participants lost weight, with 75% achieving clinically significant results. Members reported feeling more in control of cravings and lost an average of 7.4% of their starting weight within the first 12 weeks — a confident start to lasting success.

A meal plan designed for shakes — and success

The Fast Start meal plan is built around the shakes to ensure balanced nutrition and steady progress. In the first three weeks, you’ll enjoy 2–3 Fast Start shakes per day to replace breakfast and lunch, alongside a delicious CSIRO Total Wellbeing Diet dinner and healthy snacks. This phase helps your body adjust and your motivation soar. From week four, the plan transitions you back to regular meals while keeping the shakes as a convenient option whenever you need them.

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
80% reported feeling more in control of cravings after just 3 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.
