My experience in the 1:1 diet by CWP

My sponsor was amazing and kept me on track all the way. I found my favourite products which worked brilliantly for me and meant I didn’t struggle too much to stick to plan. I was really surprised to reach my target weight as nothing had worked so successfully for me in the past. I even managed to go beyond my realistic target weight to reach my dream target weight. It was the perfect diet for me.

Fantastic plan

Fantastic plan, fast but safe weight loss that’s taught me how to eat for the future and stopped me yo-yo dieting! Having a consultant that cares and is available to me is brilliant and saves sitting in big groups with no personal support like other diets

It works

It works!
I lost just over 1 stone for my holiday.
If you are unsure, like I was. Don't hesitate. Give it a try. The meals are nice. My plan was easy to follow and my weekly weigh ins were relaxed thanks to Karen my consultant.

Best diet I ever did and I lost 6 stone…

Best diet I ever did and I lost 6 stone on it and no nasty side effects just plenty of choice. I love the way you can combine it with everyday foods and everything is calorie counted for you. I still follow the plan in my everyday eating because it’s so easy and I’ve maintained my weight too.

This weight loss plan really works!

After trying every weight loss plan out there this was the only one that worked! I loved the fact I had my very own One2one consultant who was there for me every step of the way. The products were so nice and the plan was easy to follow the weight literally dropped off and I have been maintaining since loosing 4 stone after learning the way forward with portion control.

The best plan I’ve ever done

The best plan I’ve ever done! My baby was 1 at the time and I needed convenient fast weight loss. I honestly felt incredible on the products (I did step 2) and enjoyed my main meal with my family. I lost 3 stone in 10 weeks and have now been maintaining since 2013!

If you’re thinking of giving this a try, do it! But do it properly and be careful with your choice of consultant. Make sure they offer exactly what you’re looking for in terms of support. Good luck! X

Don’t think about it…do it!!!

I was thinking about doing the 1:1 diet for a while, every other diet failed and I just wasn’t getting anywhere.
I first looked at the website which was very informative and I got excited to start. It was really easy to find a consultant near to me on the website.
To be honest they all sounded lovely! They had been on my journey and that made me feel comfortable.
My first appointment was amazing, it was like talking to a friend.
I loved the one to one face to face and my consultant put me at ease with any worries I had.
She made a plan for me and it was brilliant.
She touched base with me during the week and it was nice to have the support.
The products are really nice and it just didn’t feel like I was on a diet!
I did step 3 through my journey so I could have an evening meal with my family.
The app is fantastic, lots of recipes and I loved seeing my progress which was very motivating.
For the first time I was losing weight, with support & feeling good..
I lost a total of 2.5 stone!
The best bit, the support doesn’t stop once you’ve reached your goal.
It’s there for as long as I want it.
My consultant took time to get to know me, my lifestyle and my weaknesses. She helped me every step of the way and I couldn’t have done it without the 1:1 Diet and the amazing support!
Thank you 1:1 Diet for making me feel amazing again!

Success on The 1:1 Diet

When I took the plunge to do The 1:1 Diet, I had no idea how much I’d enjoy it, I thought I’d scrape through like I’ve done on all the other diets, loose some weight but end up putting every pound and more back on but 3 years on there hasn’t been a single pound gained!
Everything about it I found so enjoyable, I loved every single meal replacement product, I looked forward to consuming them, no preparation, fuss free, low maintenance, the way it worked around life and work and how it was making me feel, inside and out, which is why I found it so easy to succeed and the icing on the cake were the incredible weekly results, in 14 weeks I’d lost 4 stone and a went on to loose a total of 6 stone, all in about 7 months.
The first week or two like any other diet is tough, but when I got my first weeks weighing, it just spurred me on for the next week and then on!
It was money well spent, you can’t put a price on your physical and mental health and this has changed my life completely, the confidence I have is incredible and loosing the weight has cured all my ailments, I feel amazing and I’d recommend this diet to anyone 100%

The best diet ever!

I can honestly say it's the best diet ever for quick, long term results!
So nice to have one to one support throughout to keep you on track. It's not easy to start with, you'll even think your crazy to attempt it but after a couple of weeks it gets easier and you never feel hungry!
I lost 5 stone and it's still off!
What have you got lose!!?
