Yes, We’re A Little Different

At Thin Within, we’re not a diet program, we’re a whole person program, Yes, body, but also mind and spirit. Because when those three are flowing in harmony, change comes quickly.

Shame has no place with us. But kindness? Gentleness? Love? Ah, those we embrace in full measure.

Won’t you join us?

As a way to get to know each other we’d like to offer you access to a premium-style membership portal—for free. Launch your Thin Within Journey toward life-changing physical, emotional, and spiritual health with instant access to videos and a handbook to guide you in building a Thin Within life!

The Heart of Thin Within

It’s not about your weight, it’s about your heart.

It’s about knowing who you are.

It’s about knowing how deeply and vastly you are loved.

It’s about no longer beating yourself up for how much you weigh.

It’s about transforming your mind, because when the mind is truly renewed, the body will follow.

What People Are Saying

Hi! We are Heidi Bylsma-Epperson and Michael Epperson


We could tell you we lost weight once a long time ago and never gained it back. But that’s not the truth.

I (Heidi) have gained and lost, gained and lost.

And that has taught me (Heidi) the deepest lesson of my life.

I needed to learn that this body I’m living in is just a container for the real me. A me that is loved beyond measure, a me that is delighted in by my heavenly Father, a me that isn’t defined by the scale, a me that is stepping into the beauty of not hearing even a whisper of condemnation, a me that has truly been set free.

If you long for the same, please join us! So you can get to know us better, we’re offering a free  Build a Thin Within Life Handbook in downloadable and printable PDF format.
