Nutrition & Lifestyle Guides from our GPs

The evidence on diet and lifestyle is frequently oversimplified, often contradictory, and sometimes wrong by the time it reaches a headline.

Patients ask us about nutrition and lifestyle more than almost any other topic, and the answers are rarely as simple as the advice they have already read online. These guides look at what the research actually shows: on diet and cardiovascular risk, ultra-processed foods, supplements, alcohol, sleep, exercise, and the lifestyle factors with the strongest evidence behind them. We cover the topics we are asked about most in clinic, written by GPs who apply this thinking every day and who understand that sustainable change is more useful than a perfect protocol nobody follows.

Our Approach

We try to separate signal from noise. The Mediterranean diet has decades of robust evidence behind it. Calcium supplements have a more complicated story. Cold plunges are interesting but the evidence is limited. We say so, clearly, rather than overstating what we know. Exercise remains the single most powerful longevity intervention available, and sleep is a clinical variable we take as seriously as blood pressure. These are not lifestyle opinions — they are clinical positions supported by evidence, and they inform how we advise patients in every consultation. These guides bring that thinking online, on topics from muscle growth and recovery to dietary sugar, alcohol, and what your wearable is actually telling you. Nutrition and lifestyle consultations can be discussed as part of any GP appointment or health screening package.
