Programmes | 121 Dietitian

At 121 Dietitian, our bespoke nutrition programmes are designed to support individuals with complex dietary and health concerns. With over 30 years of experience, Gillian Killiner has developed structured programmes that aim to deliver meaningful results efficiently and effectively.

Her team provides in-depth nutritional assessments, health checks and targeted treatments. In addition, we use specialist tools and evidence-based strategies to help optimise your health.

Why Our Programmes Are Built to Get Results

Many people find it frustrating to attend repeated appointments and receive only small pieces of information each time — when everything could have been covered in fewer, well-planned sessions.

For example, you may attend one appointment only to be told you need to return multiple times. Six sessions later, you may have gained very little while juggling time off work and additional costs.

However, having only a single appointment without follow-up can also be problematic. Specific advice often requires review and adjustment to ensure it’s working for you.

Because of this, our programmes are structured to provide clarity, direction and measurable progress from the outset. As a result, we aim to reduce unnecessary repeat visits while still ensuring you have the right level of support at every stage.

Ongoing Support Throughout Your Programme

With our programmes, you are supported every step of the way rather than left to manage alone.

You will receive bespoke plans, practical recipes and structured shopping lists. In addition, we may recommend blood testing or targeted supplements where appropriate.

Importantly, our goal is to help you achieve meaningful progress within the first two appointments — without committing you to endless and costly sessions.
