Hi, I'm Catherine!

I would love to help you!

So, what is your dream?

What is your goal?

Is it similar to mine?

I wanted to lose a few kilo’s- Eight kilos was my goal. I wanted to feel better about myself. I longed to fit clothes from high street shops, and get myself fitter. I wanted to look a bit younger too!

In 5 months I had achieved that and more! I lost over 18 kilos*, gave up sugar- and believe me that changes your life! Two years later it’s still off . I learned how to manage my food to manage my weight- with The 1:1 Diet by Cambridge Weight Plan- I had the tools to succeed. 

Key to my success was the support and guidance from my consultant. She understood the plan inside out, and had the knowledge and experience to support me to not only lose weight, but to maintain that loss.

Whatever your reason for wanting to lose weight, I  can help you every step of the way. I’ll provide one to one support and weekly weigh-ins, to keep you focused and motivated.

 My passion is to help you achieve your dreams of losing weight, keeping it off and provide you with the skills to manage your weight forever. Just like me!

Losing weight and dieting can seem like a daunting task, especially if you are doing this on your own. Where other diets have left you without support, or there has been no encouragement from a REAL person, you can be rest assured that as your personal consultant I will be with you on every step of your journey.

"I came on plan in April 2018 and I've lost 3 stone. I can't tell you how pleased I am with the results and with Catherine’s guidance I know I will keep it off. I've learned how to manage my food intake and how my body and food relate. 1:1 Diet by Cambridge Weight Plan is so much more than shakes- it’s a holistic approach to long term results. Call Catherine and ask her to help you achieve the same results I have.  You won’t be sorry you did!"

"I've been steadily putting on excess weight since my late 30s and now in my mid 40s decided enough was enough. Catherine has been invaluable in helping me with my weight loss journey. She checks in regularly to see how I'm getting on and gives me heaps of encouragement, plus tips for when I have a social event so I don't get off track. I am only a few weeks in with the Cambridge Weight Plan but am already down a size and am feeling a lot better for it!!  "

Jude Lee

"I can strongly recommend Catherine Hardysmith as a 1:1 consultant. Catherine gives you daily encouragement and tips to get you through difficult periods and I haven’t felt hungry once. She is very inspirational and very accommodating. A pleasure to work with on this journey ????"

"I’ve been sitting at an unhealthy weight for over 15 years.  Many diets and food plans were tried as weddings and holidays passed without much success.  I heard about the Cambridge 1:1 Plan and now the weight is falling off.  Catherine’s been instrumental in ensuring that I know all about the programme providing me with advice, knowledge, motivation and tips to staying on plan.  Catherine’s encouragement has allowed me to be comfortable with my eating habits – both while staying on plan and on the odd food adventure out.  Over 1.7 Stone in 5 weeks and still going.  Absolutely brilliant."

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.
