About the Book…
Why We Drink Too Much is an evidence-based exploration of alcohol use, drinking culture, and public health, written by British surgeon and researcher Charles Knowles. Combining scientific research, medical insight, and lived experience, the book examines how alcohol became embedded in society and what modern research reveals about its impact on behaviour, wellbeing, and long-term health.
Inside the book, readers explore:
The science of alcohol’s effects on the brain and body
Cultural and historical drivers of drinking behaviour
Evidence around alcohol use and health outcomes
Psychological and social influences on consumption
Questions shaping modern alcohol research and public discussion
Designed for readers seeking clarity rather than instruction, the book supports informed reflection on alcohol use and wider societal attitudes.

FAQs
Below are a few example questions about alcohol, the science behind drinking, and the book Why We Drink Too Much by Charles Knowles. You can explore more on the “Ask the Author” page and the “FAQs about Alcohol” page elsewhere on this site.

I think that this is possible although many would disagree. The medical position is that there “is no level of alcohol consumption that is safe”. I think that if the occasional drink brings joy in people’s lives then this is OK. It is simply a question of balancing the pros and cons (what I call the drinking scales). The problem is that for many of us, the scales are not very accurate.

I think society is definitely changing its views, especially in the younger generation where about one quarter of 16–25-year-olds now abstain from drinking. I am not big on fashionable anti-corporate or anti-government narratives regarding motivations to drink (we have been manufacturing alcohol for 15,000 years and animals also chose to consume it) but I think we can rightly question why so little has been done to curb the harms and societal cost of alcohol – especially in the UK. This is not party political – it is economics. At the time of writing this, the UK Prime minister has just returned from selling Whiskey to China.

There is no single threshold at which alcohol suddenly becomes harmful, but risk increases as consumption increases. In the UK, current guidelines suggest keeping intake below 14 units per week, spread over several days, as a way of limiting long-term health risks rather than guaranteeing safety.
If you’re interested in how these guidelines were developed, the Science Updates section explores the evidence behind alcohol and health in more detail.
-
Why We Drink Too Much explores the biological, psychological, and cultural reasons humans consume alcohol. The book combines scientific research with personal insight to examine our complex relationship with drinking.
-
Health exists on a spectrum, and many people who drink alcohol also engage in healthy behaviours. However, alcohol offers no health benefit of its own, and its effects need to be considered alongside sleep, diet, exercise, and mental wellbeing.
“A compelling and fascinating exploration of why we drink—and why some of us can’t stop. The author lays bare his soul in a raw, honest account of his struggles with alcohol, interwoven with world-class scientific insight into the brain, genetics, and the powerful pull of this drug. A must-read for anyone, especially those seeking to understand the hidden forces that drive us to drink too much."
Dr Andrew Jenkinson, Bestselling author of ‘Why we Eat too Much’.
