"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!!!" - Kerri Brown

This easy to follow programme is based on decades of scientific research and I'm a huge advocate for intermittent fasting. Designed to help improve sleep, support hormone balance and mood, reduce inflammation in the body and increase cognitive and mental health, G16:8 is a gentle approach focusing on healthy eating and nourishing the body rather than counting calories.

You'll select an 8-hour eating window that suits you, during which you'll focus on healthy, nutrient-dense, balanced meals. The kit features Feel Great Fibre and our Slim Me capsules, as well as a daily prebiotic to support your body during the day and to help reduce cravings. Following your 8-hour eating window, you'll fast for 16 hours, most of which is likely to be while you sleep.
