Intermittent Fasting Plans and Nutrigenetics Testing for people in the London 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’re in the London area and 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.


"Hi Kate, just wanted to give you a progress update. I’ve completed 3 weeks of the plan and have lost 14 pounds. Am restarting phase 1 again today and plan to continue until I lose the baby weight I put on. Not sure if I will continue to lose weight at this rate but am very pleased with the results so far!"
(R Minhas, 43, London).


"I am 10 weeks into the plan and I am already at my goal weight (lost 16 lbs) but I am carrying on as am sleeping so much better and have way more energy. Best I have felt for a long time."
(M Panton, 31, Data Analyst, London)


"My main reason for going on the plan was that I’ve suffered from Irritable Bowel Syndrome (IBS) since I was a teenager so I wanted to find a way of eating that helped reduce the symptoms, as well as make me feel more confident and energised. I don’t own a set of scales but I definitely felt my stomach getting flatter after the first two days, and general bloat around the mid-section and thighs disappearing. Also, my IBS symptoms (bloating, sluggishness etc.) have pretty much gone, which is great!"
N Stylianou, 34, Journalist, London.


 I have lost 4kg in 2 months on this plan and it has been so straightforward – I actually haven’t felt like I even tried to!"
P Morgan, 42, London, Investment Banker.


"Even though this is not a quick fix “diet” I have lost an inch off my waist in the first week on Phase 1 and 6lbs! I don’t even feel deprived at all. I am looking forward to seeing the results of 6 weeks on the plan."
T Rossi, 53, Health Worker, London


"I feel alive on this plan and total energised. Am 4 weeks in and I have already lost the last 9lbs I couldn’t budge and I am sleeping better, which is a major relief."
S Law, 38, Dental Nurse, London


"I went on the plan after seeing the review in The Evening Standard where the journalist had her IBS improve. I have IBS for 12 years and nothing has worked until now. I think all I can put it down to is that I am eating right for my genes. I think everyone would benefit from eating based on their genes. Have recommended to lots of people. Thank you The What IF Plan – the plan has helped me so much."
R Peters, 57, Civil Service, London
