The only diet that has worked for me.

This diet is so easy. I am useless in the kitchen so my nutrition generally is not the best, but the products are so easy to make. I don't need to take any supplements as all products have all the vitamins and minerals added so I am getting a fab boost too. Its the only diet where i have managed to lose fat quickly, other diets won't work for me as I have chronic pain and going through the menopause. The best thing is the support I have from my consultant. She is really there for me. I couldn't lose weight on my own, I have tried so many times. I recommend this diet. You get the results and there's support after too.

The 1:1 Diet changed my life

My 1:1 Consultant phoned me every day, encouraged me and shared my pride when I lost 4 stones in 3 months, I really
enjoyed the products and felt fitter than I had in years. Knowing each product provided 1/3 of my daily nutrition and knowing that research was carried out at Cambridge University made it a very safe way to lose weight. She helped with maintenance to keep my weight stable. I had no more knee pain and was able to return to nursing.

If you're serious about losing weight, this diet WILL work for you

This is the only diet that ever worked for me. I lost 3.5 stone in 3 months and it literally changed everything about my life. It seem a little bit expensive and some weeks I questioned whether I could justify the expense but it was a short term expense and it was honestly worth every penny.

Losing the weight took the personal misery out of my life and allowed me to participate in life without being held back by my weight.

It was all on a one to one basis so no group weigh ins and I had access to my consultant 7 days a week in the form of texts and calls on top of the weekly appointment so there was heaps of tailored support.

That was 13 years ago and I haven't regained the weight because my consultant showed me how to essentially reset my metabolism and make easy and sustainable changes to my eating habits.

This diet changed everything for me. I looked and felt so much better. My sleeping patterns improved. My patience grew and I was less irritable. My clarity of thought became significantly better. My energy levels went through the roof and my skin noticeably improved. All that plus I could get into a size 8-10 and look good in it so if you are serious about losing weight and are prepared to follow the plan without cheating then this WILL work for you.

Trust the process...it works!

I lost weight over 11 years ago and have maintained it ever since.
I was looking at a completely new weightloss approach (I was especially done with group settings) after being a yo-yo dieter all my life.
The plan gave me the reset I needed. I also learned so much about my body and how it reacted to different food groups (I was peri menopausal at that stage) that it gave me the tools I needed to then maintain successfully.

Changed my life

Sixteen years ago, I embarked on my journey with the 1:1 Diet, and I can confidently say it was a transformative experience for me. I managed to lose 2 1/2 stone in a remarkably short period, and what’s even more impressive is that I've maintained almost all of that weight loss since then.

What I found most appealing about the 1:1 Diet was its simplicity and structure. The plan was straightforward and easy to follow, which made it much less daunting than I initially thought. The range of products available catered to various tastes, so I never felt deprived or bored during my journey.

The weekly consultations were a game-changer for me. Having a designated time to check in with my consultant held me accountable and provided the support I needed to stay on track. These sessions were not just about weighing in; they were an opportunity to discuss my progress, celebrate my wins, and address any challenges I faced. This consistent support was paramount to my success and kept me motivated throughout the process.

Overall, my experience with the 1:1 Diet was incredibly positive, and I can genuinely say it changed my life for the better. I now have the tools and knowledge to maintain my weight loss, and I’m grateful for the journey I embarked on so many years ago.

The diet changed my life.

The diet changed my life, I was as very overweight and had some health issues. I found the 121diet by CWP online. I contacted my consultant went and met her she was lovely, she supported me.
The meal replacement products all included the vitamins and minerals I needed to be healthy and happy on the diet.
4 months later I was 5 stone / 31kg down.
I have kept nearly all of that weight off since 2013. I can’t recommend the 121 diet enough.
