This is totally up to you. For best results we recommend at least 4 weeks, however if you are investing in a long lasting change (which will save you money and time), you may wish to commit for longer. Getting healthy doesn’t happen overnight! If your order multiple boxes but have to reschedule for some reason, your pre-paid boxes are valid for 1 year from the date of purchase.
If you want to test the water so to speak, you can always try our 3 day box or London weekend box first as a one-off.
