Health and Fitness God’s Way for Life to the Fullest

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 in good shape, 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’s not about rocking the hardest abs or getting that perfect model body. It’s about enjoying life to the fullest. It’s about being there for your family and loved ones 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 had a heart to take care of ourselves as well as we do others?

Fully Alive uncovers and unpacks the Word on health. It’s time for the next chapter in your life. You don’t have to stay overweight, out of shape, and ashamed of your body. You can be fit and healthy. You can be Fully Alive!


“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. I no longer see how I can sincerely love the Lord and willingly ignore the fact that He absolutely has a “best” for me in this area and that I was bought and paid for and that it is my responsibility, no, my privilege, to willingly bring this part of who I am under submission to Him. Why? Because it is His good pleasure that I live fully alive. Open your heart, read this with a willingness to learn, and the victory will be yours. I journey with you. It is indeed, war.”  —Sarah Musick, Christ-follower, wife, mother of 6 (with 7 on the way), and worship leader

“For nearly a decade, I have enjoyed building a friendship with Deryl and Tracy that now can be described more as family. Being given the honor to mentor with Deryl as he worked this year to complete this God inspired mission, has more than blessed me personally. I have grown in my understanding of how every aspect of our lives is so important to God. I have learned to respect and love how He made me so that I can serve His purpose for my life reading through the chapters of this book. I encourage you to be prepared for your heart to receive the message God has for you as you take the journey to read Fully Alive. You will discover God’s heart and design for your health!”  —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, Social Media and Communications Consultant

“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 Horning, CIHC, Founder, Energetic Wellness Coaching
