Are you ready to help people live happier, healthier, and more fulfilled lives? Health has become complicated for average people to understand. The right book can simplify matters by cutting through the clutter and delivering no-nonsense facts in an actionable plan.
Health book buyers want books that offer evidence-based guidance to improve their physical and mental wellness. Their top concerns are nutrition, sleep, and holistic health.
The same buyers are willing to spend money on products that complement the main book, like meal planners, mindfulness journals, and self-care journals. If you’re planning to enter this popular field, consider creating a complementary product to sell with your health book.
“Health” is a huge subject. You can choose a variety of subgenres that include:
Start by defining the simple, clear promise of your book. Is it a 12-week plan to increase flexibility using ancient Japanese longevity secrets? Is it a guide for first-time weightlifters who have never set foot in a gym? Maybe it’s a guide for living a happy, fulfilled life despite a serious diagnosis. Your promise should be short, snappy, and enticing to readers who are struggling with the problem your book promises to fix.
While you’re developing your core promise, think about your book’s target reader. Name their age range, health status, and other traits. Dig deeper to think about the reasons they normally face obstacles when trying to improve their health.
Are they too busy to find the right time? Are they overwhelmed by complicated routines or hard-to-find supplies? Do they have little extra money to spend on health food or exercise equipment? Name the problem they’re having. Explain how your plan addresses that obstacle and helps them get over it.
Readers of health books want evidence-based advice based on the latest research. You must prove that you’re a credible source they can trust.
When providing your research findings, choose peer-reviewed, scientific journals. Interview qualified experts. When you report the findings of a study, don’t state the findings as established facts. Always say the study “suggests” or “seems to conclude” something.
If you don’t have health credentials, you can still build credibility in the reader’s mind. Focus on your ability to analyze the research, your interviews with experts, and your experience helping others achieve their goals.
In a health book, it’s critical to keep your ethics. Be conscientious about saying upfront—and often—that the advice in your health book should not be considered medical advice. Encourage your reader to consult their own trusted health experts, especially if they’re dealing with specific conditions.
The publishing industry has certain standards for self-help and how-to books. Those categories include health books. Here’s a guideline for structuring your book to fit those standards.
Stick to a shorter length. Most health books range from 50,000 to 70,000 words. That’s considerably shorter than the average novel. Divide your book into 8 to 12 chapters plus front and back matter. Keep chapters short and readable with clear subheadings, callout boxes, and actionable lists.
Use the introduction to tell the reader your personal story. Describe the promise offered by the book. Explain how to use it.
Readers benefit from living examples. It’s helpful to create characters who are struggling with the same issues that they are and to show them how they overcame those problems. You can use actual people you’ve worked with, or you can create fictional composite characters. Don’t use actual people’s names or identities without their written, signed permission.
In the first and second chapters, explain the science that underlies your book’s premises. Use clear, simple language that demystifies the scientific information you’re sharing. If you’re using sample characters, introduce them here.
In the third and fourth chapters, lay the foundation of your plan. Take the reader through the steps they’ll need to take to be ready. These steps will ensure the person has everything they need to stick to the plan. Help them develop the right mindset for success. This might include things like:
In this chapter, you present the full, actionable program the reader will follow. Start with a quick overview that lists each of the steps. Follow with detailed instructions for each. Include tips and pointers for success. Focus on action. Include progress markers and signs that the plan is working.
Follow the plan with an outline of what readers can expect as they follow it. Note the changes they’ll experience, and point out the ways their bodies and minds are changing as they stick with it. Anticipate upcoming obstacles that the reader is likely to face, and offer ways to counter those problems. Encourage them to stick with it.
No plan for a complete health overhaul is complete without long-term maintenance. In this chapter, you’ll outline a plan for staying on the path of better health. Invite the reader to keep the book as a resource, and tell them they can restart the program whenever they want a boost of good health, or if they feel they need even more improvement.
At the end of each chapter that focuses on the plan, include:
In the closing chapter, include information about the studies you used and the experts you interviewed. Provide resources for readers who want to continue learning about the subject.
Use a warm, friendly voice that combines empathy and encouragement. Make it clear that you believe in the reader. As a health book writer, you are a combination of coach and teacher. You’re instructing the reader, but you’re also a source of encouragement and support. You may be an expert in the topic, but don’t talk down to your readers. It’s the quickest way to lose them.
Good teachers know that supplemental materials can reinforce what they’re teaching. Use worksheets, habit trackers, affirmations, and ways to celebrate small wins. Make it easy for readers by creating grocery lists, recipes, and simple, numbers-based progress trackers (for instance, minutes of movement, amount of healthy fiber or healthy fats in a meal, or number of good nights of sleep).
How do readers know your plan will work? User feedback is an important part of any self-help book.
