Hi, I'm Heidi, I'm a part of a multi award-winning team and I cover East Sussex, Kent.

I get it! I have tried multiple diets over the years, and none of them really worked or fitted in easily with my lifestyle. Then I discovered the One2One Diet and my life changed!

What’s the difference? A huge range of products, feeling satisfied at each meal, simple to follow diet plans, but the real game-changer – one to one support.

I have lost 4 stone so far and you can too! Having someone in your corner, cheering you all the way and being there when you really need them is what I offer.  I would love to share everything I know with you so that you can have this success for yourself - let's do this together!

I offer online consultations and virtual weekly weigh-ins, alongside daily support via text, WhatsApp, and over the phone. But if technology isn't your bag, then don't worry, I also offer in-person consultations and weigh-ins at a social distance. You choose whatever is going to work best for you.

If you want someone who understands what being overweight is like and can offer you the kind of support you really need, then I’m your woman! 

Get in touch via phone, email or my social media channels, or just hit the big pink button at the top of this page and request a callback. I will always respond straight away, as I totally get that when you're ready, you are really READY!

"I had gained weight at the beginning of lockdown and felt completely out of control, right from the start I felt comfortable with Heidi and knew she would be the right person to support me. Heidi has been amazing, her knowledge, positive attitude and never-ending encouragement meant that in just 4 weeks I have lost 1 stone 2lbs. I am over the moon with those results and know that Heidi will be with me on the rest of my weight loss journey giving me so much confidence to reach my goal. I would recommend her to anyone."

"Heidi is brilliant! I was nervous about going on The 1:1 Diet but Heidi explained everything clearly and thoroughly. She is always available for answering questions, recommending recipes and top tips to help achieve your weight loss goal. Its been four weeks so far and I've shed over a stone! The proof is in the pudding, and you can even have puddings on this diet too! I highly recommend contacting Heidi if you are serious about sorting out your weight. Thank you Heidi!"

How do I find the right Consultant?

When you put in your postcode, you’ll see all the Consultants nearest you. Don’t worry if they’re not on your doorstep – lots of our Consultants are happy to come to you. Take a look at their profile and read what the dieters they have helped so far say – that should help you find someone on your wavelength. If you want to find out more before making an appointment, you can call, text or drop them an email.

How’s this different to other diet plans?

The 1:1 Diet is a lot more flexible than other weight-loss plans and it’s the ONLY one that gives you dedicated, one-to-one support from your own personal diet Consultant. That means your diet is designed for you, and only you. Together with your Consultant, you’ll work out an easy-to-follow eating plan that fits with your routine and gets you the results you want.

What’s the Awards and Achievements panel on Consultant’s webpages?

You might have noticed each Consultant has an awards and achievements panel on their profile. Being a Consultant brings loads of benefits and as they build their business, Consultants achieve awards for their hard work. This might be from superb support to all of their clients to help them hit those weight-loss goals, to helping others in their team build their own successful business. The 1:1 Diet is all about recognising and rewarding these efforts and part of the reward is giving Consultants badges on their webpage, to show you what they’ve achieved.
