Intermittent Fasting Plans and Nutrigenetics Testing for people in the Bristol area

The What IF Plan is the world’s first personalised Intermittent Fasting weight loss programme. It works with your body, not against it.

With our Intermittent Fasting plan you can achieve your happy weight, fall in love with your body again and feel confident. Within weeks you can be slimmer, healthier, happier and energised.

How does it work?

You do a quick saliva swab at home and send it to our UK lab in a pre-paid envelope for a nutrigenetics test and analysis. Then, within four weeks you can start the What IF Plan.

But nutrigenetics testing is just a small part of the process. We also gain insight into your genetic profile, your goals, lifestyle and environment which all contribute to a new, healthier you.

If you would like to find out more about Intermittent Fasting benefits there are many interesting, scientifically backed studies available, which add weight to how effective Intermittent Fasting is. It has been tested and studied and, most importantly, IT WORKS!

We wouldn’t have included Intermittent Fasting in our weight loss programme if we didn’t believe that it truly worked.

Why it works

Nutrigenetics testing reveals the way your body is built, so we can tailor your diet to fit your biology. With our help, you can use your DNA to understand your genetic make-up and finally regain control of your weight and body.

Unlocking your unique DNA using our nutrigenetics testing is the key to understanding how your body processes certain foods. Once you know that, following a personalised Intermittent Fasting plan is the most effective way to reach your goal weight and stay there, forever! It really is that simple with the What IF Plan.


 The What IF Plan has helped me massively lose my baby weight and get back in my size 10 jeans. Phase 1 and Phase 3 of the plan feel effortless and are part of my life now. I have never been on a nutrition plan like this as before it has been all about deprivation. I spent 3 days on Phase 2 and it really taught me to appreciate food and portion sizes and I now eat with mindfulness. The best bit of the plan is you can still eat treats now and again – nothing is banned. I found out I was very sensitive to carbs so I don’t need to ban these totally but I have reduced them and I feel better than ever. Would advise this plan to everyone!
