Losing weight is hard enough — juggling it alongside 80-hour workweeks as a doctor may sound impossible.
But Dr. John Go did just that, dropping 75 pounds and keeping it off for good. Today he shares the exact system he now uses to automate nearly the entire process using AI.
Through ChatGPT, he’s built a simple flow for calculating macros, designing efficient grocery lists, and even meal prepping his favorite dishes, all while staying on track to his goals.
The best part? It doesn’t require willpower, boring meals, or a single dollar out of your pocket.
If you’re busy, struggle with traditional dieting, or feel paralyzed by information overload, this guide could change everything.

How AI Makes Fat Loss Simple — and Nearly Foolproof
Dr. Go, a full-time ophthalmologist, learned the hard way that traditional dieting methods are time-consuming and often inefficient.
He spent countless hours Googling calorie formulas, tracking food manually, and meal prepping from scratch. But as he explains, most of that effort was unnecessary.
“Honestly, most of it was way harder than it needed to be,” he says. “Now, AI does 90% of the work for me. I just follow the plan.”
The key, he says, is setting things up correctly from the beginning. That starts with knowing your numbers.
Step 1: Get Personalized Macros in Seconds
The foundation of any fat loss plan is understanding your caloric needs and how much of each macronutrient (protein, carbs, fat) to eat. But finding accurate numbers can take hours of research.
With AI, it takes 10 seconds.
Simply open ChatGPT and type a prompt like:
“I’m a 35-year-old male, 5’9 tall, 165 lbs. I work a mostly sedentary job but lift weights 5 days a week and do cardio twice a week. I want to lose 1% body fat per week. Help me calculate my daily calories and macros.”
In moments, ChatGPT replies with:
- Maintenance calories: 2,550 cal/day
- Fat loss target: 1,700 cal/day
- Protein goal: 160g/day
Even better, you can ask ChatGPT follow-up questions like, “What if my weight stalls for 2 weeks?” or “How should I split meals to stay full?” It provides scientific explanations so you learn while you go.
Step 2: Keep Your Favorite Foods — Just Smarter
Most diets fail because people cut out the things they love. That leads to cravings, cheating, and burnout.
Dr. Go flips that problem on its head with ChatGPT. His process?
- Pick a favorite food — like chicken pad kra pao (Thai basil chicken).
- Find any online recipe and paste the URL into ChatGPT.
- Use this prompt:
“Make this Thai basil chicken recipe higher in protein, lower in calories, and good for meal prep. I want 6 servings. My goal is 1,700 calories and 160g protein/day. Provide a new recipe version, grocery list organized by store section, and detailed prep instructions.”
ChatGPT instantly delivers:
- Lean protein swaps (e.g., ground chicken breast)
- More veggies for volume
- Lower oil content
- Exact portion sizes tailored to his macros
- Grocery list sorted by store section (produce, protein, pantry, etc.)
“It still tastes amazing,” he says. “No bland diet food — just smarter food.”
Step 3: Streamline Meal Prep With Time-Saving AI Tips
Like most people, Dr. Go used to dread Sundays. Hours in the kitchen. Piles of dishes. Wasted ingredients.
Now, AI simplifies the process from start to finish.
Once you have a recipe, you can ask ChatGPT:
“Create a meal prep workflow for this dish that minimizes total time and maximizes efficiency. How should I batch cook and assemble it?”
For Thai basil chicken, ChatGPT replied:
- Chop all vegetables at once
- Cook a large batch of rice separately while stir-frying the protein and veggies
- Pre-portion into airtight containers
- Store extras in freezer-safe portions
Result: Prep time dropped from 4 hours to just 45 minutes.
Bonus tip from Dr. Go:
Ask: “What other meals can I make with the same ingredients?”
ChatGPT will suggest new ideas to help you reduce waste and create menu variety with minimal cost.
Step 4: Track Progress Without Guesswork or Guilt
Even the best plans need adjustments. Plateaus happen. Hunger fluctuates. Life gets in the way.
But ChatGPT can help you adapt without stress or second-guessing.
Dr. Go recommends tracking:
- Daily weight (focus on weekly averages, not single days)
- Total weekly calories and protein intake
- How well you followed your plan
Each week, plug that info into ChatGPT and ask:
“Here’s my average weight and calories this week. Am I on track to lose 1% body fat per week?”
ChatGPT will analyze your inputs and suggest tweaks — whether you need to lower calories, increase protein, add cardio, or just stay consistent.
Plus, you can troubleshoot day-to-day issues:
- “I’m starving between meals — how can I feel fuller without adding calories?”
- “I’ve stalled for 2 weeks — what’s the best next step?”
It’s like having a 24/7 coach in your pocket.
Why This System Works — Even for the Busiest People
What makes Dr. Go’s approach different is sustainability. There’s no crash dieting, no anxious tracking, and no giving up the foods you love.
Instead of relying on motivation, it relies on systems. Systems powered by AI — free, fast, and fully personalized.
“It would have saved me years of trial and error,” Dr. Go says.
He adds, “Sustainable weight loss isn’t about willpower — it’s about having the right system.”
Quick Recap of the AI-Powered Process
- Use ChatGPT to calculate your personal calorie and macro targets.
- Convert your favorite meals into macro-friendly, meal-preppable dishes.
- Generate grocery lists and prep instructions that save time and prevent waste.
- Track and troubleshoot weekly with AI to stay on-target.
No gimmicks. No starvation. Just smarter use of technology to make healthy living achievable — even with a jam-packed schedule.
