From Fit to Fat to Fit: The Journey That Changes How We See Fitness

September 20, 2023

Ever heard of “Fit to Fat to Fit”? If not, don’t worry, you’re not alone. It sounds like a tongue twister or a crazy challenge—but it’s actually a fascinating fitness experiment and TV show that flips how we think about weight loss and fitness coaching.


In this blog, we dive into the story behind “Fit to Fat to Fit,” why it’s so eye-opening, and what it can teach anyone starting their fat loss journey. Plus, we’ll sprinkle in some fun podcast banter and relatable stories from real life!


What is Fit to Fat to Fit?

  • The premise: A fit personal trainer deliberately gains a significant amount of weight — up to 70 pounds in about six months — to experience what it’s like to be overweight.
  • Then: The trainer embarks on the challenge of losing that weight and returning to fitness.
  • Why: This journey builds empathy and a deeper understanding of the struggles people face with weight loss.
  • Outcome: The trainer writes a book and stars in a TV show documenting the experience.


The Shocking Stats

  • The trainer went from 8% body fat to 32% body fat.
  • He gained 70+ pounds in six months — faster than many expected.
  • This firsthand experience revealed how easy it is to gain weight when you "let go," despite what genetics myths say.


Why This Experiment Matters

As one of the hosts, Caleigh, shares from personal experience, there can often be a disconnect between trainers and clients. Trainers might come from athletic backgrounds and not fully grasp the mental and physical challenges faced by those new to fitness or dealing with excess weight.

  • Empathy is key. Coaches who have lived through struggles with weight or fitness can better relate and guide clients.
  • Fitness isn't one-size-fits-all. Not everyone grew up playing sports or working out, so starting a journey can feel daunting.
  • Personal stories help. Many trainers today were once clients themselves — they’ve walked the path.


Real Talk: The Emotional Side of Fat Loss

The experiment shows that losing weight isn’t just about discipline or willpower. It’s a tough battle with cravings, mindset, and body resistance.

  • The trainer realized how hard the body fights to maintain its new fat.
  • This insight helped him develop empathy for clients who struggle with similar challenges.
  • The journey was not only physical but deeply emotional.


Lessons From the Show and Beyond

  • Not all “fit” bodies are functional or ready for real-world athletic challenges.
  • Shows like Physical 100 and American Ninja Warrior highlight how strength and endurance differ across sports.
  • Many “fit” people might look amazing but still feel insecure or inadequate compared to others.
  • Fitness goals should be personal and realistic—not just chasing someone else’s physique.


Why You Should Care About Fit to Fat to Fit

  • It highlights the importance of empathy in coaching and fitness.
  • Shows the complexity of weight loss beyond diet and exercise.
  • Reminds us that everyone’s fitness journey is unique.
  • Encourages those starting out to be patient and kind to themselves.


Key Takeaways: Fit to Fat to Fit in a Nutshell

  • A fit trainer gained 70 pounds to experience life as an overweight person.
  • The rapid weight gain defied genetic expectations.
  • The journey deepened the trainer’s empathy and understanding.
  • Not all trainers start as athletes—many learn through their own journeys.
  • Fitness is more than muscle—functional strength matters.
  • Everyone’s path to health and fitness is different, so comparison isn’t helpful.
  • Emotional struggles with food and body image are real and valid.
  • Personal trainers with transformation experience can better relate to clients.
  • Media and shows can misrepresent what “fit” truly means.


Final Thoughts

“Fit to Fat to Fit” isn’t just a catchy phrase — it’s a powerful reminder that real empathy in fitness comes from understanding the full journey, including the struggles and setbacks. Whether you’re just starting or deep into your fitness goals, remember it’s about progress, not perfection.

TikTok’s Latest Obsession: The “Aggressive Cut” Now let’s get into the meat of today’s episode—because TikTok won’t stop screaming about aggressive cuts . If you’ve somehow missed the trend: An “aggressive cut” is basically a dramatic calorie deficit designed to create fast weight-loss results. People love it because: You see changes quickly You’re less likely to quit early It feels like progress on steroids (without the steroids) One viral creator breaks it down like this: Find your maintenance calories using a TDEE calculator Subtract 800 calories for 3 months Eat 1 gram of protein per pound of bodyweight Get 12k–15k steps a day Lift 3–5 days per week , 6–10 reps per set Train until you’re 1–2 reps shy of failure Sounds simple… but is it smart? Sustainable? Safe? Well, that’s what we unpack—realistically, hilariously, and with zero diet-culture nonsense. The Bottom Line If you’ve ever wondered: “Should I try an aggressive cut?” “Why does TikTok think starving is a personality trait?” “Am I the only mom who doesn’t force handwashing before snacks?” This episode is for you. It’s equal parts science, sass, and “wait… did we really say that on a microphone?
