Calorie controlled nutrition for busy days.
Mediterranean style shakes designed for The Fast 800 – low in simple carbs, high in fibre and protein.
While we recommend eating real food first, we understand people live busy lives and cannot always cook for themselves. To help people on these days, we have developed convenient, nutritional food – low in sugary and starchy carbs, high in protein, fibre and quality fats, formulated in line with our principles to take the stress out of healthy living.
Whether in place of a sandwich when you are busy at work, instead of a slice of toast on your way out of the door, or instead of a pizza at the end of a demanding day – our shakes can help take the stress out of healthy living.
Our shakes are 100% natural, 100% vegetarian and contain no artificial additives. They contain a carefully chosen blend of whey or vegetable protein, coconut, almonds, minerals and vitamins.
We offer Original and Vegan versions.

And, importantly, try not to aim for full meal replacements, but eat as a snack or a replacement meal from time to time, for example when you’re too busy to cook for yourself. Remember, in the long run real food is always best.
*If you have an inflammatory bowel condition, talk to your regular GP as an increase in fibre can have an impact on your condition.
