What my slimmers say about my support... (updated September 2020)

"Isabelle is a fantastic consultant. She is there whenever you need her and really keeps you motivated to stay on plan and reach your targets."

Ruth McVey 32

"I have been a costumer of Isabelle since just after Christmas 2019 and I have found her very professional. If I have any questions, I only have to send a text message and she responds very quickly. I reached my goal in June 2019 and I now look forward to our monthly  weight ins and catch up. I have no doubt I will continue to maintain my goal weight with Isabelle as my consultant. I highly recommend Isabelle to anybody wishing to begin a lifestyle adjustment. "

Cathy J.Heaton 74

"Isabelle is simply amazing. From the moment I met her I just knew she would be 100% behind me all the way."

"Isabelle made me feel so comfortable and confident. I am excited to see what the next couple of months will bring. With Isabelle's support I know I will hit my goal!"

Karen Creed 44

"Isabelle is a fantastic consultant, who really knows her stuff. I was really apprehensive as I had so much much to lose, but she put me at ease from the very beginning, her positivity rubs off on you."

"So far she has helped me lose 7 stone."

"Isabelle has a fantastic range of products to choose from so you never get bored with what you eat. She goes above and beyond to ensure your success and has provided door to door delivery since lockdown."

"Best decision I have ever made."

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.
