Hi, we're Karen & Fergus!

Karen and Fergus

Welcome from Karen and Fergus.

Would you like to take control of your weight?  Whether you just want to look your best for a special occasion or for longer term health reasons, you're in the right place.

After our own experience of the plan (a combined 9 stone lighter*) we can confidently recommend it to others. We subsequently trained as consultants so that we can help others who want to make a change in their lives too.

The 1:1 Diet by Cambridge Weight Plan is designed to help you get the weight off in a safe and healthy way - and keep it off.  It did it for us and has done for thousands of others too.  This is not a fad diet - it actually works. Compelling medical evidence supports the benefits of the The 1:1 Diet.

We offer a positive and supportive approach to help you. You'll get 1-2-1 assistance - no group weigh-in in front of a crowd of strangers. A plan tailored to your needs and goals. The meal replacement products provide a tasty, nutritious, measured and convenient way of following the plan. You don't experience constant hunger, making it relatively easy to stay on plan while you steadily lose the excess weight, whether it be a few pounds or several stone. The CWP male slimmer of the year 2018 shed an incredible 17 stone.  It can be done!

Starting on the journey can be a little daunting but we will be there to guide you along the way.  If you have a friend or spouse who would benefit from the plan too, it can bring the added advantage of being able to support each other. Situations will arise where you face temptations that test your commitment, but the easiest option is simply to keep to the plan.

Being able to fit back into those clothes that were just too good to throw out - well that's an awesome feeling.  Being able to climb stairs without getting out of breath - fantastic. Getting compliments from everyone on how good you look - priceless.  Reversing medical conditions like type 2 diabetes - life changing.

We cover Edinburgh and the Lothians from our bases in Straiton and Corstorphine.

Just text, call or email to set up a free and confidential, no obligation consultation.

Testimonials from our clients

"I overheard a conversation where someone was saying to Fergus that he looked like a "shadow of his former self".  I asked him what he meant, and Fergus talked to me about CWP.  I told him that I’d been struggling to lose some weight for a couple of years, and he suggested that I should give CWP a try.  I managed to reach my target weight loss of 8Kgs in just 6 weeks* and the best part is that I have managed to keep it down there after the completion of the program with Karen and Fergus' great support."


"“Having had hypothyroidism problems for many years and constantly struggling with my weight, I have managed to achieve losing 2 stone 4 pounds* so far! Karen and Fergus are such an inspiration with their own CWP journey.  They have been a massive help in my success to date, finding what was best to suit my health. I know that they will be there to help me reach my goal on my continued weight loss journey.” "


"I have found the plan really easy to follow and it fits around my lifestyle with a mixture of products that need microwaved and others ready to eat or drink."

"I have found Fergus and Karen very friendly, encouraging and supportive as I journey to reach my goal."


"I’ve been on plan now for 3.5 months.  The results have been remarkable and better than I could have hoped for.  I did not expect to lose 3.5 stone so quickly and I’ve now reached my target weight.  The support from my consultants Fergus and Karen has been brilliant.  They’ve kept me motivated and supported at our weekly check ins and whenever I have sent them a message seeking advice they’ve always responded straight away.  I will not hesitate in recommending The Mackays to anyone looking to start their own weight loss journey."



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.
