Plain terms for a free programme.
TATSERRUN is a free education and lifestyle programme. It is not medical advice, diagnosis or treatment, and it does not prevent or cure any disease.
If you have a medical condition, are pregnant, or take prescribed medication, consult your doctor before changing your diet or your activity level. If something feels wrong while following the protocol, stop and seek medical advice.
Results differ from person to person and nothing here is a guarantee that you will lose weight or reach any particular outcome.
Honest daily entries. Fabricated data makes the study worthless for everyone else in the cohort, and is grounds for removal.
Enrolment is free until 31 December 2026. There is no card, no upsell and no hidden charge. If that ever changes, it will change for new participants only, and you will be told in advance.
You can leave at any time, for any reason, and ask for your data to be deleted. No penalty, no explanation needed.
