Life-changing – and I never thought this diet would be for me!
I was sceptical at first and had convinced myself from misinformation that a diet of meal replacements was not for me. How wrong was I?!
After exploring the facts and chatting it all through with my amazing consultant we decided that Step 3 would fit perfectly with my lifestyle. It suited my family routine, my budget, and the timescale I was aiming for. I originally set out to lose 3 stone, but the plan was so easy to follow that I actually reached my ultimate goal – losing 4 stone! Which I have maintained for over 18 months.
I still use the products daily as part of my maintenance routine. They’ve become part of my everyday life – not just for convenience, but because of the health benefits I’ve felt from using them.
The support from my consultant has been second to none. Having someone who truly understands the journey, and who is always there to guide and encourage you, made all the difference. It wasn’t just a diet – it was a full support system.
Quite simply, this has been the easiest and most effective diet I’ve ever done. I honestly can't recommend it highly enough.

The only plan I would ever use

The only plan I would ever use. The support of my consultant was incredible and 100% contributed to my being able to go on and lose over 15 stone. No other plan offered me the weightloss option alongside that personal individual tailored support

3 stones lost in 3 months

I followed Step 1a of The 1:1 Diet by Cambridge Weight Plan for my wedding.

I lost 3 stones in 3 months.

The range of products is very varied, something for everyone! You also get 100% of the required vitamins, minerals, nutrients needed.

The plan is straight forward and works. I have maintained my weight loss since.

Best weightloss program

I was apprehensive about this new way of losing weight. I went on plan in 2019 and with the support of my consultant I lost 2stone. What a transformation it made to my life and the way I looked at food and now i look and I feel great.

I would definitely recommend this weight loss program.

Consultant support

For me, the best thing about this diet is having my own consultant. I feel like I have someone to hold me accountable, we have a video call once a week and I find that keeps me motivated. The products are nice too, I especially like the ready made shakes.

It always works for me

The 1:1 diet is the only diet that works for me. I have an under active thyroid and even though I take medication the weight still creeps in and I find it impossible to lose it. That is why I love the 1:1 diet. I know I will lose the weight and get back to my ideal weight range. Also the one to one meetings with the consultant are fabulous. If I have any problems or messed up (cheated!) then my consultant has some wise words to help me draw a line! I am back into my slim clothes in no time 😊

My consultant was really there for me

My consultant was really there for me.

And supported me every step of the way on my journey.

The products taste great. And the flexble steps enabled me to have holidays, days out and celebrations and still lose weight.

I know my consultant is there for maintenance, and I can dip on and off plan wheneever I need to, to reset my boundaries.

Its changed my life. x

A weight loss program that actually works

I started this program on the 2/2/25 I had gained weight due to having surgery and being immobile. I found my consultant Gemma on Instagram my first appointment was via a video call from that moment she gave me the confidence and belief that I could achieve my goal she has created an amazing support group providing genuine care and advice. The products are varied I have a very sweet tooth so enjoy the bars but there is an array of products to choose from. To date in 12 weeks I have lost 1st 7 lbs . I was impressed by how quickly my weight reduced with no dip in energy levels I would recommend the 121 diet to anyone who wishes to loose weight and feel better

I’ve used other diets and lost 2 stone so far

I’ve used other diets and lost the weight but as soon as it’s lost you gain so quickly and double what you lost goes back on. This is because there is no help to maintain. So for me the 1:1 diet saved me from yo-yo dieting and helped with the maintaining. 100% worth all the effort and great support with 1-1 face to face you feel it’s catered to you. Allows you to open up and discuss what your food triggers are as no one else can hear you.

Great support, tasty products and a simple plan

My consultant was so supportive throughout my journey to target and beyond into maintenance.
The steps are easy to follow. The products are yummy, my favs- apple & cinnamon porridges, peanut bar, cappuccino shake. I also have a protein rich meal alongside my products.
I lost 5 stone in 6months and have never looked back
