Shake up your gut health

Sketch of intestines indicating gut bacteria and health benefits

A happy, healthy gut environment (your microbiome) is the epicentre for maintaining many different aspects of your health.

Of course, the most obvious is keeping you “regular” (goodbye to constipation and diarrhoea), but a robust microbiome can also support mood regulation, better sleep and a strong immune system. It can even influence the likelihood of developing allergies, and their severity if you do! All of these things, along with the gut’s ability to help manage a healthy weight, make it abundantly clear that, for long-term health, we’ve got to start from the inside.

What is the microbiome and why is it important? 

The microbiome consists of trillions of bacteria, viruses, fungi and other microbes that live mainly in your large intestine or colon – some good and some…not so good. Together these organisms weigh around 1-2kgs and, until relatively recently, they have been largely ignored.

Over the past few years, a number of scientific studies have shown that having the right variety and proportion of “good” bacteria in your gut is vitally important for your long-term health. It’s a bit like rainforests being vital for the overall health of the planet.

We also know that by eating the right foods and practising a lifestyle that nurtures a healthy microbiome, your gut produces substances that act as natural mood boosters and can help reduce anxiety.

As you get older, having lots of “good” bacteria living in your gut is increasingly important because they help you fight infection and prevent the onset of type 2 diabetes, as well as depression and common gut disorders like irritable bowel syndrome (IBS).

Why are The Fast 800 shakes so good for your gut?

We developed The Fast 800 shakes to provide a quick and convenient way to get gut-loving nutrition when time or circumstances make it tricky to eat a meal. Made from natural ingredients, The Fast 800 shakes help you look after your gut health by providing a good source of fibre, prebiotics and probiotics.


Dietary fibre is important for digestive health and regular bowel movements. Fibre also helps you feel fuller for longer, can improve cholesterol and blood sugar levels and can assist in preventing some diseases such as diabetes, heart disease and bowel cancer.

The Fast 800 shakes are high in fibre, containing an average of 14 grams of fibre per 100 grams. The fibre in the Fast 800 shakes mainly comes from flaxseeds. In addition to being high in fibre, flaxseeds are also packed with nutrients, including anti-inflammatory omega-3 oils.


Prebiotics are a type of plant fibre that your body can’t absorb, but when digested, encourage the growth of “good” bacteria in your gut. You’ve probably heard of probiotics, which are healthy micro-organisms that rely on prebiotics to survive and thrive. Prebiotics and probiotics work together to help maintain a healthy digestive system.

The Fast 800 shakes contain inulin, a prebiotic fibre found in many vegetables like asparagus, onion, garlic, chicory root and Jerusalem artichoke. Inulin helps keep you feeling fuller for longer and helps control blood sugar levels, all the while feeding the probiotics in your gut and encouraging them to grow.


Probiotics are live micro-organisms found in bacteria, yeast or fungi, that help keep your digestive system healthy by controlling the growth of harmful bacteria. Probiotics promote a healthy balance of gut bacteria and have been linked to a wide range of health benefits, including improved digestive health, immune function and weight loss.

The Fast 800 shakes contain a probiotic blend (Bacillus Coagulans) which helps keep your gut feeling healthy!

The Fast 800 is an innovative approach to healthy living and weight loss based on the latest scientific research. Developed in conjunction with Dr Michael Mosley, the online programme is for those that need more support and guidance for achieving long lasting health. If you join the online programme, you will receive Mediterranean-style menus with weekly HIIT and resistance training plans that are tailored to your level of fitness.
