Jason Vale’s Juicy Oasis Boutique Health Retreat and Spa is on the shores of a beautiful Portuguese river that’s been dammed (so more of a lake), about 90 minutes’ drive from Lisbon airport, near Sertã.

At the end of week one

If you’re thinking about a juice fast/feast and you don’t want to go too hard core, then this luxurious resort might well be the retreat for you. You get delicious juices at 10:30, 13:30, 16:30 and 20:00, plus various additional shots (e.g. ginger and beetroot or celery and cucumber). It doesn’t sound like a lot but it’s more than enough to keep you going without any hunger pains.

One of the advantages of a juice feast like this is that you have more energy and you certainly need that if you are going to engage in the wide-ranging optional timetable: daily walks, yoga, rebounding, volleyball, throwball, meditation … swimming (in the pool and also the lake), sauna, massage treatments … relevant and inspiring films such as May I be Frank and Simply Raw … there’s plenty to do to keep your mind off food … and plenty of opportunities to help increase your fitness as well.
