Lifestyle Medicine:

What is Lifestyle Medicine?

Lifestyle medicine is evidence-based clinical care that helps people make sustainable changes to improve health and reduce chronic disease risk. The British Society of Lifestyle Medicine describes it as care that supports behaviour change through person-centred techniques, focusing on key lifestyle drivers such as nutrition, movement, sleep, mental wellbeing, relationships/social connection, and reducing harmful substances and behaviours.  

The six pillars of Lifestyle Medicine

In practical terms, lifestyle medicine is built around six core areas (often called the “six pillars”):  

• Healthy eating

• Physical activity

• Restorative sleep

• Mental wellbeing / stress support

• Healthy relationships / social connection

• Minimising harmful substances and behaviours (e.g., smoking, excess alcohol)

These pillars are also reflected in the Royal College of General Practitioners lifestyle medicine framework, reinforcing that this is a mainstream, clinical discipline—not a wellness trend.  

What Lifestyle Medicine is (and what it isn’t)

Lifestyle medicine is not “anti-medication.” Where medicines or hormones are appropriate, they can be vital. The aim is to ensure that treatment isn’t limited to symptom control alone—while also addressing the underlying drivers that influence long-term health.  

It also goes beyond generic advice. British Society of Lifestyle Medicine emphasises three elements:

1. recognising wider socioeconomic determinants of health,

2. using proven behaviour-change skills, and

3. applying knowledge of the six pillars.  

   
   

What does a Lifestyle Medicine consultation look like?

A lifestyle medicine consultation typically explores:

• your health story and priorities (what matters most to you)

• symptom patterns and triggers

• habits and routines across the six pillars

• realistic, personalised next steps, with follow-up to review progress and refine the plan

The approach is collaborative and practical—focused on what is achievable in real life, not perfection.

How does Lifestyle Medicine relate to Functional Medicine?

Lifestyle medicine and functional medicine share a similar “root-cause / whole-systems” mindset—asking why symptoms are happening and what may be driving them.

A simple way to think about the relationship:

Functional medicine and lifestyle medicine share a common emphasis on treating the whole person rather than isolated symptoms, but they differ meaningfully in their focus and methods. Functional medicine is a systems-biology approach that seeks to identify and address the root causes of disease, using detailed patient histories, advanced lab testing, and an understanding of how genetics, environment, and lifestyle factors interact to drive illness in each individual. Practitioners often consider investigating areas such as gut health, hormonal balance, and chronic inflammation to build a highly personalised treatment plan. Lifestyle medicine, by contrast, centres its therapeutic approach on evidence-based behavioural interventions — primarily nutrition, physical activity, sleep, stress management, and the avoidance of harmful substances — as the first-line treatment for chronic disease. Where functional medicine may employ a wide toolkit including supplements, specialised testing, and targeted protocols, lifestyle medicine keeps its lens deliberately on the six pillars of healthy living as both prevention and cure. In practice, the two can complement each other well, but functional medicine tends to ask why a patient is unwell at a biochemical level, while lifestyle medicine focuses on how sustainable daily habits can restore and maintain health.

Why it matters for women’s health

Women’s health concerns—such as perimenopausal symptoms, metabolic health, stress load, sleep disruption, mood changes, fatigue, and gut symptoms—are often influenced by multiple interacting factors. Lifestyle medicine provides a structured, evidence-based framework to support these drivers while working alongside conventional medical care where needed.
