The Tudor Dixon Podcast: Ozempic, Obesity & the Body Image Crisis – Guest: Aimee Donnellan

Air Date: December 12, 2025
Host: Tudor Dixon
Guest: Amy Donnellan, author of Off the Scales: The Inside Story of Ozempic and the Race to Cure Obesity

Main Theme & Purpose

This episode explores the history, science, and social impact of Ozempic and other new weight loss drugs. Host Tudor Dixon interviews financial journalist Amy Donnellan, whose new book dissects how Ozempic became a cultural phenomenon, the complex relationship between food, body image, and health, and what these drugs reveal about obesity, stigma, and modern life. The conversation examines not only the drug’s medical origins but also how it sparked a seismic shift in attitudes about weight, food, and beauty standards.

Key Discussion Points & Insights

1. Origins and Rise of Ozempic

• Drug Development
  • Ozempic was originally developed for diabetes by Novo Nordisk. Its potential for weight loss was discovered during the rollout and subsequent patient observations.
  • Amy Donnellan learned of Ozempic during the pandemic, while reporting on pharmaceutical companies benefitting from ‘virus vices’ — unhealthy behavior spikes during lockdown.
  • "That was sort of the Ozempic effect. And that was the first time I had ever, this was 2020, the first time I had ever really heard or seen anything about Ozempic." (Amy, 03:40)
• Hollywood Discovery
  • The drug became a “miracle” in Hollywood around 2018, promoted by doctors to celebrities.
  • This contributed to the decline of the body positivity movement and revived ‘thinness’ as the aspirational standard.
  • "It crashed right into…really the peak of body positivity…once people realized there was this shot that they could take that could allow them to be thin, it seems like for a lot of people, body positivity just kind of went out the window." (Amy, 05:26)

2. Changing Food Environment and Societal Shifts

• Portion and Processed Food Changes
  • The serving size at fast food chains has increased dramatically—what was once “super size” is now the normal size.
  • Industrial food's proliferation coincided with more women entering the workforce, fueling demand for convenience meals full of sugar and preservatives.
  • "There was a big, big push at this time…then, as you're right, once people realized there was this shot…body positivity just kind of went out the window." (Amy, 06:42)
• Addictive Qualities and Marketing
  • The food industry's tactics, like free refills and cartoon mascots, have unwittingly encouraged overeating and fostered unhealthy relationships with food.
  • Host and guest discuss feeling "betrayed" by needing to scrutinize product labels as a normal part of food shopping.
  • "It's tiresome that we're even in this situation…there were some sort of cynical things that they did…cereal boxes, having cartoons…that to me, that feels like you're manipulating a consumer." (Amy, 20:48)

3. Genetics, Stigma, and Understanding Obesity

• Nature vs. Nurture
  • Case studies show that not all obesity can be attributed to poor eating habits or willpower, as illustrated by identical twin and family case studies.
  • "There doesn't really, in my opinion, seem to be much rhyme or reason to people becoming obese…that is, I would definitely think that the food industry is a factor in that." (Amy, 07:11)
• Genetics and Evolution
  • Amy recounts scientists’ frustration at industry leaders who refused to accept obesity as a disease with genetic roots, not just a character flaw.
  • "You survived if you could retain fat, that's what allowed you to…propagate the species…But…our bodies just don't work in that way" in today's abundant food environment. (Amy, 10:01)
• Stigma and Social Implications
  • Real-life stories reveal that people are treated differently after weight loss, even by close family.
  • "People treat you differently if you're not overweight…even my own father took longer to talk to me than he had in the past. That was kind of stunning." (Tudor, 11:36)

4. Ozempic: How It Works, Side Effects, and Who Uses It

• Physiology of the Drug
  • Ozempic mimics a powerful stomach hormone (GLP-1) that signals fullness after eating, powerfully reducing appetite and cravings for unhealthy food.
  • Prescribed for people with BMI > 30 or with associated health risks, not healthy-weight individuals.
  • "There’s a chapter of the book that really kind of goes through the side effects…most people…experience some level of nausea, diarrhea, like gastric issues." (Amy, 27:41)
• Microdosing & Abuse
  • Some healthy-weight individuals are obtaining the drug through dubious means and microdosing for cosmetic reasons, often risking serious side effects.
  • "People tell me all the lengths that their friends have gone to to get these drugs…Another thing is that they might like wear a bulky coat so they look bigger…" (Amy, 27:01)
• Long-Term Issues and Muscle Loss
  • Rapid weight loss from Ozempic causes much greater muscle loss than diet and exercise alone:
    • Diet/exercise alone: ~25% muscle loss during weight loss
    • Ozempic: ~40% muscle loss (especially risky for older adults, leading to falls and fragility)
  • "If you're on ozempic, you lose 40% muscle mass." (Amy, 39:32)
  • "That is really bad if you are older because you become more prone to falls." (Amy, 39:33)

5. Food Industry’s Current Response and Future Ramifications

• Industry Pivot
  • Big food brands are scrambling to market “healthier” products (protein pasta, fiber-rich breads, etc.) as Ozempic users crave less processed food.
  • "The people who are going on these drugs don't want their food…they walk right past the Doritos…and go straight for the produce aisle." (Amy, 23:56)
  • Attempts to mimic “mouthfeel” of whole foods in processed products are ongoing and somewhat dystopian:
    • "Big food is like…we've decided it's a mouthfeel thing…so now we're going to make it crunchier." (Tudor, 31:18)
• Philosophical and Societal Shifts
  • Some experts believe these drugs will become as commonplace as statins, with most Americans eventually using them due to high obesity rates.
  • "I've spoken to people who say that this will be like statins in the future." (Amy, 34:06)

6. Body Image, Desperation, and Unmet Societal Needs

• Desperation to Be Thin
  • Amy shares an anecdote: a woman not medically overweight pursues Ozempic illegally, willing to risk a shorter lifespan for thinness.
  • "She said, I would rather die thin at 60 than live until I was 80 and be fat." (Amy, 42:24)
• Body Positivity’s Limits
  • Both acknowledge that, despite cultural campaigns, deep-seated biases about weight persist among individuals, families, and institutions.
  • "Obviously our body positivity campaign didn't actually work." (Tudor, 43:29)
