The What IF Plan

The world's first Intermittent Fasting Weight Management Plan based on your DNA

The What IF Plan is the world's first Intermittent Fasting Weight Management programme based on an individual's DNA and blood markers.The What IF Plan DNA Test looks at genetic markers associated with weight loss and weight management.The plan also includes a baseline at-home finger-prick blood test, which considers potential causes as to why you may not be losing weight. The test looks at your thyroid function to check if it is your metabolism which may be the reason why you aren't losing weight. It also includes HbA1c (diabetes check), iron (to test for anaemia, a prime cause of fatigue and low energy), and vitamin D, which research has shown to impact body weight.

Intermittent Fasting has proved so effective for weight loss and maintaining that desired weight loss, but it isn't for everyone - individuals with Type 1 diabetes, uncontrolled thyroid issues, of the elderly or underweight should avoid. Instead, these individuals should opt for the Diet and Fitness Test instead, but if you want to give Intermittent Fasting a go or have tried it with success in the past just sign up here.

The What IF Plan includes the DNA test, finger-prick Weight Loss blood test, a 30-page report, meal plan, recipes, and a 60 minute Skype/phone consultation with a MSc. qualified Nutritionist to discuss your DNA results and report, and any specific nutrition concerns you may have.

How it Works

Once you have bought your DNA test online and we have received your order, we will send your DNA kit out by Royal Mail first class.

When you receive your DNA kit you will see that it contains your swab, your sample envelope (to put your DNA swab in once you have taken your sample), and a pre-addressed/pre-paid envelope which you place the sample envelope in.

Once the lab receives your DNA sample, it will take approximately 14-21 days to receive your DNA report.

Unfortunately, we are unable to process any blood samples, which are out of the UK. However, please enter the following promo/discount code at the checkout (NOBLOOD) and the blood test fee will be deducted from the cost for clients outside of the UK.

Anna Williamson“I have to say my initial scepticism has been proved wrong. I don't like "diets" but this is more a lifestyle plan (works out your DNA and genetic food intolerances) which I have to say has had some great results, not only have I lost a dress size of my baby bulge. but my hormones and mood swings have calmed down, and my overall mental, emotional and physical health feels on an even keel. I wanted to sort out my sluggishness and bad diet and this seemed worth a crack. I can tell you - it is!”

Nuria“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!”

Alex Leigh“The What IF Plan® is amazing. I have suffered in the past with depression and then post-natal depression and I wanted to look for something other than medication that I could do to help myself feel better. I discovered the DNA diet and fitness plan, which has transformed my life. I feel great knowing that I am eating and exercising in life with what my body needs and it has made a huge difference. Thank you so much.”

Alex Leigh, Fashion Model

Sophie Barton“Kate is incredibly informative and detailed. For me, the plan has been fantastic both physically and mentally. It's enabled me to make the right food choices, with the result that I'm much less bloated and my waist is smaller. More importantly though, the difference to my emotional wellbeing has been fantastic. I'm less anxious, more balanced and more positive. It literally feels like a cloud has been lifted.”
