About us

The 1:1 Diet, originally known as The Cambridge Diet, was launched in the UK in 1984 and has helped thousands of people worldwide lose weight and live healthier, happier lives.

Developed, tested and validated by expert nutritionists and researchers

“Your body gets all the nutrients it needs and uses its fat stores for energy. And because the diet is high protein, you don’t lose muscle mass or have cravings.”

Where it all began

Cambridge Weight Plan goes way back. We can trace its roots back to the 60s, when biochemist Dr Alan Howard started to research the perfect diet. Since 1984, when The Cambridge Diet became commercial in the UK, thousands of people from all over the world have used our help, support and products.

We’d like to think that the dieter's experience of Cambridge Weight Plan is a bit like having a friend by their side. But not like a nagging friend. More like a really supportive, knowledgeable, wise and experienced friend cheering them on.

In 2018, the plan was renamed The 1:1 Diet by Cambridge Weight Plan because we’ve always been about one-to-one. Our biggest asset has always been one-to-one relationships, whether that’s between a dieter and their consultant or between a consultant and their team. Our brand is built on these relationships and we wouldn’t want it any other way.

Our Corby HQ

Our home has been sunny Corby in Northamptonshire since 1986.

In 2014, the company became employee owned and a member of the Employee Ownership Association (EOA). We're super proud to say we won the Employee Owned Business of the Year Award 2019 for our dedication and commitment to empowering employees.

We operate from three buildings on the Weldon North Industrial Estate in Corby, where we manufacture all our sachets, bars, meal packs and tubs. Our Ready to Drink range and Step Up meals are made by manufacturing partners both in Yorkshire and Europe.

The 1:1 Diet by Cambridge Weight Plan is proud to be a zero-landfill company. All the waste products generated at our site in Corby are either sent for recycling or used in energy from waste reprocessing.
