Hi, we're Kerry & Mark !

Let's make that change

Hi we are Kerry and Mark and between us we have lost so far 7 and a half stone on the 121 diet. 

I started back in October 2021 and Mark joined me to give support and be a better version of himself. A little bit about me, I have been overweight all of my life and have tried every diet on the market and really need to do something this time to improve my health . I decided the 121 diet was for me as I could do the plan on products and food too and really liked the sound of the 121 consultations . 

I am based in Wallington South London but can support people all over the country whether you decide you would like a face to face meet up or virtual over the internet I will be here to support you . 

You can also find me over on Instagram Kerry.boom_121diet where I blog my journey and post recipies of my meals. 

Whether you have one stone to lose or 10 I will support you every step of the way.

* The weight lost and/or timeframes are particular to this slimmer. Everyone's weight loss journey is unique to them.


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.
