Small Group Coaching

Winter 2019 Session runs the week of January 7th through week of March 11th ("Rain Dates" are the week of March 18th).

Coaching Groups Begin...


Are you tired of the same old same old? Do you really want to start 2019 with the same old resolution--and yet another DIET?!


  • Deprivation in order to lose weight?

  • Maintenance that isn't ANYthing like the diet?

  • Trying to eat more of the foods you don't care for and not eating AT ALL the foods you DO like?



What other option IS there?

No…not another diet.

Isn’t that a relief?  

Thin Within is more about inviting God to change you…to transform you from the inside out... than it is about losing weight or “eating healthy.” This is real Romans 12:2 life-changing transformation!

Therefore, do not be conformed by the pattern of this world, but be transformed by the renewal of your mind. Then you will be able to test and approve what God's will is, His good pleasing and perfect will. ~ Romans 12:2


Dieting vs. Thin Within

What is the cost?

Ten Weeks of Group Coaching for ONLY: $350

(or two payments of $187.50)

But...does that price sound too steep?

Consider with us...You receive:

  • Long term value in learning and practicing using mind renewal tools
  • Unlimited access to the curriculum long after you complete the coaching group!
    (Be refreshed or use it to renew your mind!)

  • Additional input, feedback, questions and answers in real time by two coaches.
    Not one, but two! :-D

  • You will want to make different choices in the long haul!
  • You will save any money you spend on this program in food you won't be buying anymore!

Investing your time will bear fruit not just in your eating and attitude towards food and your body, but also in your character as you begin to apply the tools and principles you learn to other aspects of your life. Many participants find that what we teach in our coaching groups actually helps them in business, finances, or in overcoming intimidation with a difficult employer or family member. The rewards are plentiful!

Yes, but does it work?

will you lose weight?...WE did!

What do you get when you join the Thin Within Winter 2019 Group Coaching Program?

  • Daily (or hourly, if needed) support in our "secret" Facebook group (privacy is protected)
  • 10 weeks, 24-lesson curriculum with videos, audios, and workbook lessons all downloadable at the Thin Within Academy.
  • Weekly live group coaching calls with a small group (no more than 10) that will encourage you on your journey as you do for them on theirs.
  • Accountability, tips, tricks for those who want peace with their eating and with their body - at the level YOU need it!
  • Facebook connection throughout each week. (We do require membership in our Facebook group so you can receive assignments and announcements).
  • New "Porch Chat" and "Heart 2 Heart" videos created by the coaches each week and uploaded to our Facebook groups. These short videos are usually inspired by topics and needs that surface during our coaching calls.
  • For those who stick with the group, unlimited continued access to Fresh Wind, Fresh Desire at the Thin Within Academy, even beyond our session.
  • Prayer requests and prayers, sharing together of prayers, praises, gratitude given to God.

The "Game-Changer" for you might be our Thin Within small coaching group!

  • Would you like to...

    • Be a healthy size in 2019?


    • Eat and enjoy a broad variety of normal foods?


    • Experience peace with food, eating, and your body?


    • Gain freedom from fear of gaining weight or not losing?


    • Be equipped with tools to experience transformation of your thinking, beliefs, and actions?... and weight?

    • Experience the abundant life Jesus promises He came to give us?

    • Integrate your faith with a most vital aspect of life?


    • Develop meaningful relationships with others that will continue long after our coaching group session is over?

    God never intended for food to torment you, but to be a wonderful, delightful gift of His provision!


What can you expect in the Thin Within Winter 2019 Group Coaching Program?

  • Download and print Fresh Wind Fresh Desire, Thin Within's latest new curriculum to take with you into time with Jesus.
  • Begin each of 10 weeks with a short video (or two) that will preview our focus for the week.
  • Build intimacy with a small community and with the God of the Universe in our small, private Facebook group, including two coaches and 5 to 7 others who will walk with you on your journey for 10 weeks, and very likely beyond.
  • Share prayer requests and know you are being covered in prayer even as you pray for others.
  • Special goodies and surprises will be uploaded by your coaches each week. These include videos that we create just for you and your group members.
  • Struggling with a potential difficult event? Wondering how to navigate the waters of a wedding celebration or Holiday Picnic? You can ask your group members and coaches about it in our secret and private Facebook group.
  • Wrap up the week with a coaching group conference call. You will get to interact with your coaches and group members in real time, brainstorming, strategizing and benefiting from the experiences of your fellows.
  • Even after the 10 week session has concluded, you will maintain extended access to Fresh Wind Fresh Desire, including all the videos and audios at the Thin Within Academy.

Our curriculum includes:

  • Learning how to release extra weight and to be a natural God-given size by eating NORMAL food. No diet foods or off-limits lists.
  • Tuning in to your physical signals of hunger and satisfaction.
  • Developing a comprehensive view of our God through bible study and praise.
  • Freeing ourselves from the tyranny of the bathroom scale and leaning, instead, on the God-ordained hunger scale.
  • Finding a SANE approach to exercise! Joyful and worshipful!
  • Breaking free from the guilt/shame cycle.
  • Shifting our view of "Success".


Thin Within is a non-diet, mindful eating approach to lasting weight loss. Those who use the Thin Within approach eat normal food between the parameters of physical hunger and physical satisfaction. It doesn’t take much food and, by eating less of the foods we love, we are able to release extra weight!  It sounds so simple and really IS simple. We agree that it isn't easy, but it is SIMPLE.


Christina Motley and Heidi Bylsma (pictured to the right), veterans and coaches for Thin Within, invite you to join them for an intimate 10-week  journey of the heart and mind this Fall. There will be no more than a total of 8 participants in each  coaching group. Heidi and Christina will lead all groups through the study of Fresh Wind, Fresh Desire, a new curriculum we have written and designed just for you

Who's leading these groups?

Meet Heidi Bylsma


On this journey since 1999, Heidi released 100 pounds in under a year using the Thin Within principles. After remaining a healthy size for 7 years, during a challenging season, Heidi reverted back to old habits and behaviors. Desperate to experience the blessing of transformation that only God can perform, Heidi has discovered renewed joy in her walk with God and weight-release journey as she renews her mind with gusto once again!

Meet Christina Motley


As one of Heidi's one-on-one coaching clients in spring of 2014, Christina Motley was already a veteran of Thin Within. She nevertheless experienced challenges and struggles with consistency. It wasn't until she began to diligently renew her mind that she experienced the transformation that God alone can accomplish! Christina has been one of our coaches since we *began* the coaching groups. She is a DYNAMITE addition to our coaching program!

Our Assistant Coaches


Kelly has led many Thin Within Facebook classes going through the Rebuilding God’s Temple workbook series.




Kathryn has been at work supporting many of our Facebook groups including all of our coaching group members. She has also led Rebuilding God’s Temple workbook series classes. To date, Kathryn has released 65 pounds.

Now available to all coaching group participants

Thin Within Coaching Groups use our newest curriculum: Thin Within: Fresh Wind, Fresh Desire.

Access is available for you at the Thin Within Academy and is included in the coaching price. Where else will you get two enthusiastic Thin Within coaches, a great 24-lesson curriculum, 10 weekly coaching calls and 7 other participants to brainstorm, support and pray for you on this journey?!


Coaching groups are the most effective means to experience transformation. More than the large Thin Within workbook classes, more than the one-on-one coaching with Heidi. These small groups offer accountability, prayer, support, and tons of encouragement! Can you see yourself being a part? WE can!

Have you wondered why common sense

tells us that "Diets don't work"?

  • Accountability and support within the group are a vital part of these coaching groups. You will be a co-coach in a very real way! When you sign up, you are opting to bring all your insights to the others in the group, too. Don’t worry…We all have something to share, even if it is what we have discovered about what *doesn’t* work! :-)
  • Enjoy the enthusiasm and experience of two coaches for this more intimate journey.
  • FWFD (Thin Within: Fresh Wind Fresh Desire) includes 24 lessons as well as corresponding videos and audios. We throw out the stops and teach in detail how to use the a plethora of tools to renew your mind for your Thin Within journey. This is the GAME-CHANGER, causing us to “think God’s thoughts after him.”
  • The curriculum and coaching groups are where Christina and Heidi bring all their years of experience in Thin Within to you in a concentrated 10-week dosage!
  • We share the lessons we learned the hard way. 
  • You will be empowered to experience the blessing of  experienced sojourners. 
  • Fewer stops and stumbles happen for you on this journey as you learn from your coaches' mistakes! :-)
  • Interact with the others in your group in hour-long weekly group conference calls (accessible with a computer or phone)
  • Experience meaningful exchanges and discussion with your fellow group members and your TWO coaches (Heidi and Christina) via Facebook Secret Group.
  • In-between our weekly group conference coaching calls, we share assignments, victories, etc., in our Facebook group.
  • We begin the week of January 7th, 2019 and will end the week of March 17th, 2019.

God promises…

“Be transformed by the renewing of your mind.” (Romans 12:2).

We want to do whatever that means as our transformation hinges on it!


Even during these 10 weeks, if you “buy in,” giving everything you have, you will experience weight loss.

This IS it! The start of the *real* deal!


If you:

  • the exercises in FWFD
  • ...participate with your small intimate community of like-minded people with similar hopes, desires, and dreams
  • ...engage with the material
  • ...renew your mind

You will:

  • experience transformation from the inside out
  • deepen your spiritual life and connection to God
  • go on vacations and trips and celebrate holidays without dread that you will gain weight
  • go beyond the band-aid approach to the cause of the struggle we've had for years
  • never diet again!
