Cody Crone, a 56-year-old YouTuber, successfully transformed his health by using ChatGPT to create a personalized fitness and nutrition plan. Over 60 days, he lost 13 kilograms through disciplined adherence to AI-designed diet and exercise routines. Crone's regimen focused on whole foods, regular workouts, quality sleep, and hydration, proving the potential of AI as a free fitness coach.
, and the outcomes were nothing short of remarkable. Over the course of just 60 days, he shed an impressive 13 kilograms, dropping from 209 pounds (approximately 95 kg) to 183.8 pounds (roughly 83 kg).On May 17, Crone uploaded a video to his YouTube channel documenting the entire process—from his motivations to the structured diet and disciplined routine that helped him reach his goals. Rather than depending on popular weight loss drugs or shortcuts, he followed a focused plan centered around nutrition, physical activity, proper sleep, and hydration, all designed through an AI consultation.
"I made ChatGPT my nutritionist and fitness expert," he stated.
Crone's meals followed a minimalist yet nutrient-dense format. His day typically began with a protein-rich breakfast consisting of four eggs, half a pound of lean, grass-fed ground beef, and a third of a cup of steel-cut oats. He made sure to avoid sugar and opted for premium-quality salt along with a greens supplement to boost his micronutrient intake.
For dinner, his plate included a third of a cup of jasmine rice paired with eight ounces of lean, hormone-free, grass-fed meat, such as New York steak. He added healthy fats through either high-quality olive oil or half an avocado. Processed foods, seed oils, refined sugar, and dairy were all completely excluded from his diet.
Crone was deliberate about using the highest quality ingredients available—organic produce, grass-fed proteins, and hormone-free meats formed the foundation of his food intake.The AI-generated plan emphasized structure and discipline. Crone consumed just two meals per day within a strict eating window, ensuring no food was eaten after 5 PM. Supplementation was tailored for both pre- and post-workout needs and included creatine, beta-alanine, whey protein, collagen, magnesium, and other health-enhancing compounds.He woke up daily at 4:30 AM and exercised in his home garage at 6:00 AM. These workouts lasted between 60 and 90 minutes and were done six days a week. Crone maintained that he did not have access to a gym but did have some kettlebells at home. He bought some basic equipment, as AI suggested, and turned his garage into a mini makeshift gym.
For optimal rest, his evenings followed a strict digital detox. He avoided screens an hour before bed, used blackout curtains, and stayed away from synthetic bedding. Eating a small amount of local raw honey before sleep helped improve his rest. Hydration was also essential—he drank about four liters of water daily, stopping intake by early evening to avoid disrupting his sleep.
His nights were dedicated to seven to eight hours of deep, uninterrupted rest, free from noise, light, and electronic distractions. He also ensured he got 15–20 minutes of morning sunlight each day to support his circadian rhythm.
To track progress, Crone monitored his weight each morning in a fasted state and recorded the results in a journal, allowing AI to tweak his plan as needed.
Importantly, Crone clarified that he did not turn to any commercial weight loss products like Ozempic. His transformation was powered purely by whole foods, regular exercise, quality sleep, and consistent discipline—crafted and guided entirely through the support of artificial intelligence.
