Why You’ll Love It

GP16:8 is a less restrictive Intermittent Fasting programme for milder weight loss and weight management. It's easier to follow for people who are less inclined to plan and have busy, unpredictable schedules. You'll simply select an 8-hour eating window, during which you'll consume all meals, snacks, supplements and caffeinated drinks for the day following the GP Principles. You'll then fast for the remaining 16 hours - most of which will be whilst you sleep.

    A sustainable, stress-free programme!

    The most sustainable and stress-free programme I've ever worked with. There are so many resources to help along the way and I found the Wellness Consultation especially helpful to get started. I would highly recommend GP16:8!

    I’ve been on GP for the last year. First starting on 4:3 and losing over a stone. I found the 16:8 then helped me lose 3-4lbs a week and maintain my weight when needed. Both plans are amazing but 16:8 definitely is the one for me!!!
