What people are saying:


Check out The What IF Plan®


"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!"

"I went from a size 16 to a size 10 following The What IF Plan and it gave me more energy, I felt more control and I had way more energy to exercise. The plan is very flexible and easy to follow and if I did take a day off, it was very easy to start the next day with the two meals and 16 hour fast. I was in the best shape ever sticking to your plan (I was in size 10 River Island Jeans!) and now, I am expecting baby number 2 I can’t wait to get back on the plan once my baby is born and I get clearance from my GP!"

"I found out that I possess inflammation markers, which means my joints are prone to being inflamed and sore. Even though I’m already taking an omega-3 supplement, I found out that I needed to take even more as well as fatty acids. It makes sense for someone with my condition to have these DNA results, but once you actually see it in writing it helps you to get a better understanding of what is going on inside your body, and how you can change things through your diet. Within two weeks on the What IF Plan, my skin started to clear up! I really noticed that eating well made a difference. Also I used to moan that my skin was ‘grey’ but I have a much brighter complexion now. I’ve been having more make-up free days than ever. Within a couple of weeks my eyes looked brighter and the autoimmune ‘brain fog’ I live with daily started clearing. The What IF Plan has made a huge difference to my fatigue, strength and mental health. I have way more energy and I am even waking up easier in the morning. Also I feel fuller quicker. I’m not craving my usual sweet treats come 8pm, which is great. All in all I feel an overall sense of wellness even though I’m still in so much pain, and that is really amazing! I’m sticking to the plan now as much as I find it really easy to stay on track. The fact that the plan has given me so much choice with my meals means I don’t feel like I’m missing out on anything. If anything I’m gaining more recipes and eating things I wouldn’t usually have cooked with."

"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!"

"I wish I had known about genetically appropriate diets during my playing career, and how my body responded to nutrients such as carbs, fats, and lactose. Having this knowledge is a huge advantage in helping you achieve your weight loss and fitness goals. The USA rugby 7’s squad, which I coach, have already benefitted significantly from Kate’s knowledge, and have experienced some great results following their personalised, DNA-based nutrition and fitness plans. I am very excited to be able to offer my clients at The Athlete Factory their own genetically appropriate diets and fitness plans, too."

"In the health and fitness world, information is of paramount importance. The information I gathered from the DNA plan has enabled me to precisely design my training programs, nutrition plans and even change my lifestyle. Now I can rest assured that how I train, eat and live is perfectly in tune with my genetics. Having implemented these changes over the last 6 months, my own personal progress has been greater than I could have imagined. My improvements in the gym, from fat loss, lean muscle gain and improved performance have all exceeded my expectations. I urge all my clients to take this route so I can tailor their health and fitness plans to suit their individual genetic profile."

Jamie Sawyer

"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 well-being has been fantastic. I’m less anxious, more balanced and more positive. It literally feels like a cloud has been lifted."

Sophie Barton
Journalist/Former Closer Magazine Executive Editor

"Following my diet and skin plan has improved my skin massively - just take a look at my before and after photos! I now have a personalised nutrition plan, personalised skincare product plan and personalised skin treatment plan! I have been advised what supplements I personally need to promote optimum skin health and slow down the rate of photo-ageing. Skin treatments are a minefield, but having had my Anti-ageing Skin DNA Test I know exactly which treatments I will benefit from most, and even the right skincare products for me."
