Hi, we're Terrie & Gordon!

Terrie and Gordon Diffey

We are a husband and wife team, offering support and advice any time of the day or week, from our home or visiting you.

As you can see from the photos, I was the one with the weight issues, but Gordon lived every 'up and down' moment with me: lacking in confidence, often in despair, not wanting to socialise, feeling out of control, constantly feeling guilty that I was letting my kids and husband down and no belief that it could ever change!

I had tried every diet and trend going - know the feeling?

Then 10 years ago my daughter's wedding was looming and I decided I couldn't bear the thought of being captured on film. I had to do something and was so glad that I found The 1:1 Diet by Cambridge Weight Plan. The feelings I got on that wedding day, having got down to my target weight, were unimagiable.

Although the journey has not always been easy I have learned that it is definitely possible and it is that definite possibility and unimaginable feelings we want to give you no matter what your reasons are for searching this website: to lose weight, deal with health issues or just to find the real you.

We can offer

  • confidential, personalised 1-1 support (although family, children and friends are very welcome), ongoing encouragement and advice throughout your journey and beyond
  • a personalised plan tailored to your life style and needs
  • appointments to fit round your schedule:daytime, evenings and weekends.
  • a support network through Facebook
  • an optional photo shoot when you reach goal
  • free weigh-ins for those enjoying maintenance

We are conveniently located on School Road in Upwell but we can also travel to you in Wisbech, March, Chatteris, Downham Market, Ely and all surrounding villages.

There are no registration, joining, consultation or cancellation fees: all you pay for are the products you purchase. Cash or cards taken.

Thinking about starting The 1:1 Diet by Cambridge Weight Plan but want to know more? Call, text or email and we will be more than happy to answer any questions.

Testimonials recieved from some of our clients -

"I would like to thank you for the excellent service you provided to me and Nikki in our bid to lose weight before our upcoming holiday. With only a few weeks to achieve this, you assured us that this could be done and helped us along the way with weekly meetings, updates and even the odd text message. We are both pleased with the results of using The 1:1 Diet and the service we recieved along the way. I would therefore have no hesitation in recommending you to any of my contacts in the future. Yours sincerely, Colin Freer"

"I would like to thank you for going the extra mile and a half after your 10 minutes talk the other week. My wife, Sue has been struggling with flavours due to the side effects of chemo therapy and your water flavourings seemed like the ideal solution. I expected to have to wait a week for these products but to my suprise you offered to drop them round later. You turned up as planned with bottles of each flavour prepared so that Sue could sample them. We will certainly be recommending your services to friends and coleagues. Kind regards, Colin."

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.
