These Terms and Conditions cover two related but distinct things:
These two things work together: the 12-month commitment gives you the time to lose weight and build lasting habits; the No-Regain Guarantee™ gives you financial protection once you've done that and come off medication. If you leave the programme early, the No-Regain Guarantee™ simply does not apply.
By enrolling in a 12-month commitment plan, you acknowledge that you have read, understood, and agree to be bound by these Terms and Conditions.
The No-Regain Guarantee™ applies only to new members who enrol in and start the Second Nature Weight Loss Programme on or after 1 March 2026 on a 12-month commitment plan.
Members enrolled prior to this date, transferred from earlier programme versions, or restarting an existing membership are not eligible.
Second Nature reserves the right to determine eligibility based on enrolment records.
You must be enrolled in and have completed the full 12-month commitment plan. Members on monthly rolling plans, 3-month plans, or 6-month plans are not eligible for the No-Regain Guarantee™.
If you cancel your 12-month plan early or fail to complete all 12 monthly payments, you forfeit eligibility for this guarantee.
You must not have used any prescription weight-loss medication in the 6 months prior to starting treatment with Second Nature, including (but not limited to): Orlistat, Mysimba, or GLP-1 receptor agonist medications such as semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro), or liraglutide (Saxenda).
If you disclosed prior prescription weight-loss medication use at the time of enrolment and Second Nature accepted your enrolment and processed payment, you acknowledge that this does not qualify you for the No-Regain Guarantee™.
You must have been assessed and approved for treatment by a Second Nature clinician.
If you and your clinician decide to stop medication early — for example due to side effects, tolerability issues, or because it is no longer clinically appropriate — this does not automatically disqualify you from the guarantee. Provided you continue to engage with the Programme (coaching, behavioural support, and lifestyle guidance) and meet the other eligibility criteria, you may still be eligible to claim.
The key requirement is that any change to your medication is made in consultation with your Second Nature clinician and recorded within the Programme.
During the active treatment phase, you must:
The Programme combines prescribed medication with behavioural and lifestyle support. Eligibility requires participation in the Programme as designed — medication use alone is not sufficient.
Following clinician-guided medication discontinuation, you must demonstrate reasonable participation in the maintenance phase, including:
Second Nature may assess engagement using activity and participation data recorded within the app. Failure to meet the engagement requirements set out in this section may result in loss of eligibility, at Second Nature's reasonable discretion.
You must reach a clinically agreed goal weight during active treatment, as recorded in the Second Nature app. Your Goal Weight is the lowest weight recorded during the active treatment phase.
Your clinician may recommend discontinuing or adjusting prescribed weight-loss medication at any point during the Programme. This may happen for a number of reasons, including (but not limited to):
Medication discontinuation is a clinician-led decision made in your best interest — it is not a condition imposed to lock you into a prescription. You are free to discuss stopping medication with your clinician at any time.
Stopping medication does not mean leaving the Programme. You may continue to access coaching, behavioural support, and all other Programme features after discontinuing medication.
For the purposes of the No-Regain Guarantee™, the Guarantee Period begins once medication discontinuation has been confirmed by your clinician and a stabilised weight measurement has been recorded following the Stabilisation Period. If you stop medication without consulting your clinician, Second Nature may not be able to verify your discontinuation date, which could affect your ability to make a claim.
A claim may be made if your recorded weight increases by more than 20% of the Total Weight Lost between your Starting Weight and Goal Weight.
Example: If you lose 20 kg (from 100 kg to 80 kg) and later regain more than 4 kg (i.e. your weight exceeds 84 kg), you may be eligible for a pro-rata refund.
Weight regain is assessed after the Stabilisation Period following medication discontinuation. This period allows for normal physiological adjustment and will be determined by the clinical team. Weight fluctuations during the Stabilisation Period do not count towards the regain threshold.
All weight measurements used for the purposes of this guarantee must be recorded within the Second Nature app or submitted through an approved verification process as reasonably requested by Second Nature.
The No-Regain Guarantee™ applies for 12 months following clinician-guided discontinuation of medication.
To make a claim, you must submit a refund request within 30 days of first meeting the regain threshold (i.e. within 30 days of a recorded weight that exceeds 20% of Total Weight Lost above your Goal Weight).
Claims submitted outside this 30-day window will not be accepted.
Your refund request must include:
Requests must be sent to: support@secondnature.io
Second Nature will acknowledge receipt within 5 business days and aims to process valid claims within 30 business days.
Refunds will be prorated to reflect the proportion of weight regained beyond the 20% allowance.
Example: If you lose 20 kg and later regain 6 kg (30% of Total Weight Lost), you have exceeded the 20% threshold by 10 percentage points. Your refund will reflect the excess regain beyond the 20% threshold proportionately.
The maximum refund payable under the No-Regain Guarantee™ shall not exceed the total Weight Loss Service subscription fees paid by you during your 12-month commitment plan.
The following are excluded from any refund calculation:
The No-Regain Guarantee™ will not apply if:
For clarity: Stopping medication because of side effects, clinician recommendation, or a mutual decision with your clinician does notdisqualify you from the guarantee — provided you remain on the programme, continue engaging, and the change was made in consultation with your clinician and recorded within the Programme.
By selecting the 12-month commitment plan, you agree to a minimum subscription period of 12 consecutive months, billed monthly on the same date each month (or the nearest available date).
In return, you receive a £25 discount per month compared to the standard monthly price — a total saving of £325 over 12 months.
We understand that circumstances change. If you need to leave the programme before completing the full 12 months, you can do so — particularly if:
If you leave early:
Leaving early is not a penalty — but the No-Regain Guarantee™ is designed for members who complete the full programme. If you leave for clinical reasons, you simply return to the standard terms without the guarantee.
The 12-month commitment plan includes:
There are no hidden fees. Medication and programme support are included together in one monthly price.
At the end of your 12-month commitment, your subscription will automatically continue on a rolling monthly basis at the then-current standard monthly rate unless you cancel before the renewal date.
Weight data, photographs, and other personal information submitted in connection with a claim under the No-Regain Guarantee™ will be processed in accordance with Second Nature's Privacy Policy. By making a claim, you consent to the use of this data for the purposes of assessing and verifying your claim.
Second Nature reserves the right to amend these Terms and Conditions at any time. Changes will not apply retrospectively to members already enrolled under an existing 12-month commitment plan with the No-Regain Guarantee™, except where required by law.
Any material changes will be communicated to you via email or through the Second Nature app.
These Terms and Conditions shall be governed by and construed in accordance with the laws of England and Wales. Any dispute arising under or in connection with these Terms shall be subject to the exclusive jurisdiction of the courts of England and Wales.
