Potential results

What does a successful cycle look like?

Realistic ranges from the scientific literature on these habits — until our community's real data takes over.

−1 à −3 kg

📊 Transparency: these ranges are references from the scientific literature¹, not promises. Your body is unique — which is exactly why every challenge is measured by YOUR body checks. From launch, this section will display the community's real, anonymised results, challenge by challenge.
