Did you know the Bible offers guidelines for health and fitness? To learn how our bodies work, Deryl W. Duer spent years referring to the One who designed them. He lost more than 100 pounds in the process, and what he learned will change your life!

Most of us want to be healthier, but we’re overwhelmed. There are thousands of fad diets and workout plans out there. But there’s a plan to health and fitness according to scripture. The full, abundant life Jesus promises in John 10:10 includes our health. It begins with the decision to glorify God in every area of our life—including our bodies. It’s not about how you look, it’s about experiencing life to the fullest. It’s about being there for your family in a long, satisfied life. It’s about honoring God and serving His kingdom to our best abilities.

  • What if we treated our bodies like the temples they are?
  • What if we followed the Bible’s guidelines on what we ate and how we exercised?
  • What if we applied the principles of stewardship to our bodies as much as we do other areas of our lives.
  • What if we had a heart to take care of ourselves so we could better serve God and others?

Fully Alive uncovers and unpacks the Word on health. It’s time for the next chapter in your life. You were designed to thrive, not just survive. Experience the dynamic physical and mental energy you were created for. You can be fit and healthy. You can be Fully Alive! It all starts here. Start now!




"“Deryl Duer has written a personal, inspirational, and challenging book showing the relationship between exercise, eating right, and biblical teaching. I knew Deryl when he was at his heaviest and unhealthiest, and it has been encouraging for me to watch his transformation, as well as his growing ministry in this pivotal area. I encourage you to ingest, digest, and act on his wisdom.”"

Kendell Easley, University Professor of Biblical Studies, Union University (Tennessee)

"“I am the Sarah that you'll read about in this book. I have loved the Lord for many years, with all of my heart and mind but had never been taught about loving Him with all of my body. God began stirring in my heart this need to find out what His Word said about how to eat and care for my body. He led me to Deryl. What Deryl did for me over several months he has now done for you through this amazing book. Open your heart, read this with a willingness to learn, and the victory will be yours.”"

Sarah Musick, Christ-follower, wife, mother of 6 (with 7 on the way), and worship leader

""For years I have been reading, researching and taking part in multiple programs targeting improvement in my health as well as understanding how important what I do is to God. Through Deryl's book I have learned at a much deeper level why following the principles outlined in this book make all the difference. I challenge anyone to read this book and be prepared to see what you are missing, and how to discover how to tap into a life you have always longed for but now can achieve. Thank you Deryl for listening, writing, and giving us a practical doable application for living Fully Alive!""

Denise Needham, CSO (Chief Strategy Officer), SurveyMe, Newport Beach, California

"“Through his irrefutable testimony, Deryl exhorts us to commit to life fully. To be “All In.” His honest, direct challenges are not formed in a bubble with a Bible, but with a life that contains tragedy and triumph. The Bible informs his experiences, giving meaning to his life, and in turn, to our lives. Our culture has grown weary of soft-spoken half-truths that make us feel better about our choices. Deryl’s bold statements, backed with science and spirituality, lead us to authentic evaluation of our life now and how it could be in the future. Whether you consider yourself a health nut or a couch potato, this book will take you deeper in your understanding of complete health. Just as in the exhilarating conclusion of The Chronicles of Narnia, Deryl calls to us, “Come further up! Come further in!” Read this and gain a renewed desire to be Fully Alive!”"

Jocelynn Bailey

"“Deryl has a passion to glorify the Lord in every aspect—and especially by being a steward of the temple that God has given him. In his book, he tells the story of his own dramatic 100-pound weight loss and transformation, encouraging others to be able to make the changes, too—and not out of vanity or as an idol, but as a tool to glorify the Maker of the heavens and the earth. He uses God’s Word and his own personal experiences to remind you of the truth of the gift of obedience in all things to Christ. I encourage anyone to pick up this book to edify your spirit, encourage your mind, and motivate your body into submission to Christ. Every word of God proves true, he is a shield to those who take refuge in him. (Proverbs 30:5) May you be encouraged through the passion that God has given Deryl to proclaim this message!”"

Keri Lappi, CIHC, Founder, Energetic Wellness Coaching

""Deryl Duer is the Dave Ramsey of health and fitness, and I believe that God has given him this ministry to make an incredible difference in the American church and to start a revolution. I'm excited to see where this movement leads. This book is life changing. I read one chapter a day so that I could truly digest all the incredible truths he dives into. This isn't another "diet book" or anything like that- this is about life change, heart change, mindset change. I wish I had read this YEARS ago, but I am so grateful to have this now. I am planning on giving this away as a gift to others on their health and fitness journey, and I fully intend to lead at least one small group through this phenomenal book.""
