"You've unlocked more than 24hrs in my day. My eating patterns now add energy & focus to my day, rather than take away from it. You've made changing simple! Keep it up!"

Rich / Structural Engineer

"Siri DeMarche is a wonderful coach--I can't recommend her enough. I've been through two personal programs with her (targeting different areas of my nutrition) and have created a lasting healthy lifestyle that I am actually excited to continue."

Kayt / Director of Creative Storytelling

"I started working with Habitually Holistic after a string of failed attempts to get healthier. Siri has a shame-free, sustainable, well-rounded approach that doesn't obsess over numbers or quick fixes. If you want an approachable & compassionate coach that can help you get on track while providing the background science for her recommendations, please check her out! Highly recommend. "

Rebecca / Physician's Assistant

"I never realized I had brain fog until Siri recommended a few changes to my diet. Now I think more clearly, calmly, and have more energy. "

Ben / Outdoor Enthusiast

"...I have so much more energy in the mornings and also feel less bloated when I wake up, also helps with those late night time munchies. I've already dropped some of the body fat that I gained back from COVID. Also your product recommendations are amazing! I could go on and on! "
