Are you sick of…

Weight loss shouldn’t be
an impossible puzzle.

  • ?Putting all your energy into workouts with no results
  • ?Overly restricting your diet
  • ?Getting worn out by strict eating plans
  • ?Putting weight back on as soon as the diet ends
  • ?A lack of support on your health journey

Violet lost 6kg

“I lost 6 kilos, 8.5% of my body weight, and I am thrilled!”

“As an emotional eater I put on weight I found extremely difficult to lose, even working out all the time. The three phases are simple to follow, backed by evidence, with a realistic meal plan that allows cheat meals and drinks. It gives you the tools to keep living a healthy life after the challenge.”

The September 2025 challenge winners were George, down 8.8kg, and Michelle, down 5.6kg.
