MY NEW BOOK

The Queer Guide to Nutrition & Lifestyle

COMING 21st SEPTEMBER 2026

Published by Jessica Kingsley Publishers.

A new edition of Naked Nutrition, expanded and updated for the next chapter of LGBTQ+ health.

This book brings together nutrition, functional medicine, mental health, body image, sexual wellbeing, transgender health, HIV, party culture, addiction, recovery, and family building.

Written from clinical experience and lived reality, it offers an evidence-informed approach to queer wellbeing that goes beyond generic health advice. It recognises that health is shaped by more than just food and fitness. It is shaped by identity, stress, shame, pleasure, community, access to care, and the stories we carry in our bodies.

Practical, inclusive, and grounded in real life, The Queer Guide to Nutrition & Lifestyle is for LGBTQ+ people and for anyone who wants to better understand queer health.

My Approach

Health is never only physical. It is shaped by biology but also by identity, stress, relationships, culture and the ways we have learnt to cope. My work looks at how these parts interact, rather than reducing a person to a set of symptoms or forcing them into a standard protocol.

Nutrition

Evidence-informed nutrition and functional medicine, with attention to symptoms, energy, digestion, hormones, medication, sleep and everyday life.

Identity & Behaviour

Body image, perfectionism, shame, belonging and the patterns that shape how we eat, cope and care for ourselves.

Healing & Integration

Healing is not another thing to perfect. My approach is trauma-aware and may include breathwork, nervous-system work or altered-state integration when appropriate.

About Daniel

I’m a Functional Medicine Certified Practitioner, nutritionist, author and speaker with more than fifteen years of clinical experience.

I work across nutrition, queer health, body image and healing, bringing evidence-informed practice together with an understanding of identity, culture and lived experience.

I’m the author of Letting Go of Perfect and The Queer Guide to Nutrition and Lifestyle. Alongside working internationally with private clients and organisations, I speak about what health can look like when we move beyond rigid rules, constant optimisation and the pressure to be perfect.

MY MOST PERSONAL BOOK

Letting Go of Perfect: A Gay Man’s Guide to Healing from Body Dysmorphia

OUT NOW

Published by Jessica Kingsley Publishers.

Body dysmorphia is rarely spoken about openly, particularly among gay men. Letting Go of Perfect is my most personal work to date, bringing together lived experience and clinical insight to explore how body image, shame, and control take shape.

This book is for anyone who has felt trapped by comparison, performance, or the pressure to be a certain version of themselves. It offers a more honest alternative to quick-fix body image solutions, focusing instead on releasing the pressure of who we think we should be and returning to who we truly are.

Speaking

I speak with evidence, warmth and candour about queer health, body image, perfectionism and the relationship between identity, wellbeing and performance.

I’m available for keynotes, panels, workshops, interviews and selected advisory projects.
