GLP-1 Hub: Support, Community, and Weight Loss

Send us Fan Mail
Fiber is suddenly showing up everywhere, from soda and candy to pasta and protein snacks. But more fiber isn’t automatically better, especially when it leaves you feeling bloated, uncomfortable, or confused about what your body actually needs.

Registered dietitian and GLP-1 user Ana Reisdorf sits down with David Istier, founder and CEO of gutzy Organic, to discuss the gut microbiome, prebiotics, probiotics, and why different sources of fiber can feel different in your body. David also shares how his experience helping launch GoGo squeeZ in the United States—and the health challenges he faced while building his own company—led to the creation of gutzy.

For people taking GLP-1 medications, the central takeaway is simple: eating less makes the nutritional quality of what you eat even more important. Ana and David discuss how to look beyond protein and fiber marketing claims, prioritize real food, and find convenient options for days when appetite is low.

**IN THIS EPISODE**

- Why different sources of fiber may feel different in your body
- How fiber became the food industry’s newest marketing trend
- Why more fiber isn’t automatically better

**ABOUT THE GUEST**
David Istier is the founder and CEO of gutzy Organic. Originally from France, David began his career in food marketing and later helped launch GoGo squeeZ in the United States. After experiencing significant stress and health challenges while building his own company, he became interested in plants, prebiotic fiber, and gut health. That experience eventually led him to create gutzy Organic and its refrigerated fruit-and-vegetable pouches.

Tara Rothenhoefer was one of the earliest participants in a tirzepatide clinical trial, before the medication had a brand name. After a lifelong battle with obesity, she began the trial in 2020 at 342 pounds. Eighteen months later, she had lost 132 pounds. But when the study ended, she faced a year without medication, uncertainty around access, and the emotional work of learning how to live in a body she had never known before.

In this episode, Tara shares what changed when food noise finally quieted, why medication alone was never the whole story, and how she learned that “more weight loss” is not always the goal.

IN THIS EPISODE
- Tara’s lifelong experience with obesity, dieting, and weight stigma
- How a radio ad and a clinical-trial opening changed the course of her life
- What it was like to join an early tirzepatide trial with only a 25% chance of receiving the medication
- The role of nutrition support, movement, and gradual behavior change
- Losing 132 pounds in 18 months—and what happened when the trial ended
- Navigating medication access, shortages, judgment, and compounded medication
- Why the scale and clothing sizes can become a new kind of obsession
- Recognizing when continued weight loss was no longer healthy
- What long-term maintenance looks like after a major weight change
- Using medication as one tool in a broader, ongoing relationship with health

ABOUT THE GUEST
Tara Rothenhoefer is a wife, mom, and grandma who, after a lifelong battle with obesity, joined a clinical trial for tirzepatide in 2020 that led to her 222-pound weight loss. Featured on numerous national platforms, including The Today Show, Good Morning America, and the Tamron Hall show, she now shares her journey to encourage and inspire others, while navigating maintenance and living life in a small body for the first time ever.

Your scale isn't measuring weight...it's measuring fear, shame, and whether you believe your GLP-1 is working.

Registered dietitian Ana Reisdorf sits down with Brian Baumal, a registered psychotherapist who lost 100 pounds, kept it off for 14 years, and recovered from two eating disorders. He explains how the scale can become exposure therapy, why shame drives the "lose it fast" thinking that sets you up to fail on Ozempic or Zepbound, and how to stop tying your worth to a number.

IN THIS EPISODE
- Why weight gain on a GLP-1 sends you into a spiral (and how to stop it)
- Using the scale as exposure therapy: the CBT-E "collaborative weighing" technique
- How shame causes quick weight loss goals, black-and-white thinking, and failure
- Why Ozempic and Zepbound don't eliminate food noise completely — and why that's normal
- Habit change vs. the underlying psychology of emotional eating

ABOUT THE GUEST
Brian Baumal is a registered psychotherapist based in Toronto, Canada, trained in depth psychotherapy with a practice focused on the emotional and unconscious drivers of weight, eating, and shame. He has adapted cognitive behavioral therapy for eating disorders (CBT-E) into a weight management approach. Brian lost 100 pounds and has kept it off for nearly 14 years, and is recovered from two eating disorders — exercise bulimia and binge eating disorder.

That "miracle" peptide in an unlabeled vial isn't the same science as your GLP-1,  and the FDA is meeting this week to decide the fate of seven of them.

Registered dietitian and GLP-1 user Ana Reisdorf sits down with Tanna Donalson, PA-C, owner of Redbud Medical in Denver, where she prescribes, manages, and monitors peptides for her patients every day. After 15 years in trauma and emergency medicine, Tanna built a practice around exactly this: knowing what each peptide is, what it actually does for a patient, and how to run it safely. Together they break down why semaglutide (Ozempic) and tirzepatide (Zepbound, Mounjaro) belong in a category all their own, the seven peptides on the FDA's table, and the two questions that reveal whether a peptide provider is legit.

IN THIS EPISODE
- What a peptide actually is, and why your GLP-1 is NOT the same thing as BPC-157 or TB-500
- The seven peptides the FDA is reviewing: BPC-157, KPV, TB-500 (the "Wolverine complex"), MOTS-c, DSIP, Semax, and Epitalon
- The "funding gap" — why peptides that can't be patented never get human clinical trials
- Six things the FDA worries about in an unlabeled vial, from identity and purity to the cancer/angiogenesis risk
- The two questions that tell you if a peptide provider is legitimate (503A/B pharmacies and third-party certificates of analysis)

ABOUT THE GUEST
Tanna Donalson is a Physician Assistant and Owner of Redbud Medical in Denver Colorado. Her background is in Trauma and Emergency Medicine and she is now specializing in Women's Health and Wellness, Peptides, Weight Loss, Hormones and all things preventative care to help people live longer, healthier lives.

Your GLP-1 can quiet the food noise, but the psychologist who helped big food companies engineer your cravings says it can't erase them...and thinking it will is why weight comes back.

Ana Reisdorf, registered dietitian and GLP-1 user, talks with Dr. Glenn Livingston, psychologist and author of Defeat Your Cravings (2M+ readers), who spent years consulting for big food companies before losing 80 pounds himself. They break down why the craving center of your brain has no concept of long-term goals, why "everything in moderation" backfires, and how to use Ozempic, Wegovy, Zepbound, or Mounjaro as a training tool instead of a wake up skinny pill.

IN THIS EPISODE
- Why food cravings come back on Ozempic, Wegovy, Zepbound, and Mounjaro — and how to handle them
- The "extinction burst": why cravings get worse right before they go dormant for good
- How to stop overeating with one specific food rule instead of "everything in moderation"
- Why your GLP-1 works like a personal trainer holding the bar, not a skinny pill
- Why fasting on a GLP-1 backfires and how fast you should actually lose weight

ABOUT THE GUEST
Glenn Livingston, Ph.D. was the long time CEO of a multi-million dollar consulting firm which has serviced several Fortune 500 clients in the food industry. You have likely seen his work and appearances in many articles and news segments on major publications and media over the years. Disillusioned by what traditional psychology had to offer overweight and/or food obsessed individuals, Dr. Livingston spent several decades researching the nature of bingeing and overeating via work with his own clients AND a self-funded research program with more than 40,000 participants. He earned his Ph.D. in psychology from Yeshiva University in 1991.
