What people were sceptical about first

  • “Hannah Futrell noted that while the program was expensive, it was not as costly as IVF. She concluded it was 'so worth it' because it addressed her blood work, home products, and pantry to improve her overall health.”Hannah Futrell
  • “Jessica Montehermoso initially had to convince her husband that the cost was worth it. She now views the couple thousand dollars spent as a small price compared to the long-term diseases they are preventing by adopting this lifestyle.”Jessica Montehermoso
  • “And the price point is very affordable when you are looking at treatment options.”Kimber Krosschell

Frequently asked

How do I stop the cycle of starting a new diet every Monday and failing?
Marilyn Bright found that isolating health from faith led to a cycle of 'starting over every Monday' and giving up by Tuesday. She broke this trap by joining Fast To Faith, which integrated mindset, health, and scripture rather than just 'starving herself' through fasting. — Marilyn Bright
Is Fast To Faith just another weight loss program?
According to Marilyn, weight loss is just the surface level of the program. She emphasizes that Fast To Faith goes deep into mindset and soul work to change a person's entire life, making it a comprehensive transformation rather than a standard diet. — Marilyn Bright
What kind of coaching support does Fast To Faith provide?
Marilyn describes her coach, Melissa, as a 'cheerleader' who used compassion and scripture instead of guilt or pressure. This supportive sisterhood was invaluable to Marilyn's success in achieving her health goals. — Marilyn Bright
Is Reimagined Health worth the cost compared to IVF?
Hannah Futrell noted that while the program was expensive, it was not as costly as IVF. She concluded it was 'so worth it' because it addressed her blood work, home products, and pantry to improve her overall health. — Hannah Futrell
Can functional medicine help with unexplained infertility?
Yes, Hannah turned to Reimagined Health after conventional doctors labeled her case 'unexplained' and recommended IVF. By focusing on root causes like thyroid health, inflammation, and mental health, she was able to conceive naturally. — Hannah Futrell
Does Reimagined Health involve the partner in the process?
Hannah emphasized that the program included her husband, noting that partners often get neglected in fertility journeys. She felt it was vital that they were both on the same page and feeling their best. — Hannah Futrell

Based on interviews with Dr. Autoimmune customers · September 11, 2026

Dr. Autoimmune customers have recorded 12 first-hand video interviews with Share One since September 2025. Every figure below is a count of what those people said on camera — not a survey, a clinical trial or a marketing claim.

Asked what changed for them, 7 of the 12 described symptoms resolved or reduced, and 3 described clearer systems and processes. One of them put it this way: “In my opinion, he has more background as to what could be causing those symptoms.”

On timing, 5 people described how long it took before they noticed a difference. The most common answer was 2 weeks – 2 months (2 of them).

Dr. Autoimmune is not the only source of evidence here: 675 interviews across 123 organisations touch on functional medicine, which is what makes the comparison on this page worth reading rather than a single company's testimonials page.

“He is actually listening to symptoms of patients rather than just going for the regular standard of traditional medicine.” — Laura Moreno
