How I use AI to Optimise My Health

In 2024, I decided to take a deeper, more structured approach to managing my health. I’ve always kept reasonably fit, ran regularly, gone to the gym, and tried (and failed miserably sometimes) to eat well. I wanted to make more informed, long-term decisions about my nutrition, training, supplements, and overall wellbeing. I didn’t want guesswork or conflicting advice. I wanted something that was based on my actual data and goals.

That’s when I started using ChatGPT not just to answer questions, but as a personalised health system. Something that could understand my individual context and help me make better decisions every day.

This experience also reinforced something we talk about often at Geeky Kids, where we run coding and AI courses for young people: when you use AI thoughtfully, it becomes a powerful problem-solving partner not just a tool.

Setting Up My Health Project

I began by creating a dedicated project inside ChatGPT where I uploaded all my key data. This included recent blood tests (from NHS online and yearly checks that I do privately), a food sensitivity panel, past test results, and a summary of my routines and health history. Some of the concerning markers included elevated ferritin, slightly high cholesterol, previous fatty liver (now resolved), and reactivity to several foods including dairy, egg white, gluten, cashews, and yeast.

Once that was set up, ChatGPT could work with the full picture. It started helping me interpret patterns, identify risks, and prioritise actions based on what mattered most.

Nutrition and Sensitivity Guidance

One of the first benefits was help with managing food sensitivities. My IgG test results highlighted a list of foods I needed to avoid or rotate. If in doubt, I would just ask the model rather than having to look up the file and search for the text in a 30 page document. ChatGPT helped me understand where these ingredients might be hiding, suggested alternatives, and helped me plan meals using foods I tolerate well.

It also guided how to structure a food reintroduction process over time. I could ask which foods to reintroduce first, how to space them out, and what symptoms to monitor. It remembered what I was avoiding and gave consistent answers whenever I had to check something.

This made food planning simpler and far more personalised. It was no longer guesswork or trial and error.

Supplement Strategy Based on Test Results

Once we identified my core health priorities, ChatGPT helped build a supplement plan to support them. That included addressing liver support, iron balance, inflammation, cognitive focus, gut health, and recovery.

It also explained the timing and interactions between supplements. I learned which ones to take with food, which on an empty stomach, and how to space them out during the day. It was no longer about taking whatever was trending but about using supplements strategically and safely based on my needs.

Building a Weekly Routine Around My Life

One of the most helpful outcomes was using ChatGPT to build a consistent weekly structure around my health goals. I shared how my week typically looks, including fasting windows, training times, family meals, and commuting.

With that context, ChatGPT helped me design a routine that supported my goals without disrupting daily life. It aligned supplement timing, meal planning, and fasting around real constraints like school runs, work hours, gym sessions, and cooking for the family. It helped me maintain energy on longer fasts, balance recovery after workouts, and simplify decision-making throughout the week.

The plan evolved over time. Whenever something changed in my schedule, sleep, or energy, I could ask how to adjust the routine without losing momentum.

Real-Time Health Decisions

The system became something I use daily. Because it has full access to my health data and preferences, I can ask specific questions and get relevant, reliable answers. Some typical questions I might ask:

• Is this food safe based on my test results?
• Can I take these two supplements together on a fasting day?
• Suggest a recovery-friendly dinner using only my safe ingredients.
• What does this blood marker mean, and what should I change in response?
  
• What can I order from Just Eat today? Or even sometimes I would be in a restaurant and just take a picture of the menu and let it help me decide. 

These are small but important decisions that come up often. Having a system that understands my biology and goals has made it easier to stay consistent, make fewer mistakes, and feel more confident about what I’m doing day to day.

This kind of interaction is very similar to how we encourage kids to think when learning to use AI. In our AI coding courses at Geeky Kids, we teach young learners how to build and use tools like ChatGPT in creative, context-aware ways whether for games, apps, or projects that solve real problems.

Why This Changed the Game

This setup doesn’t replace healthcare professionals, but it fills the gap between appointments and test results. It gives me a trusted assistant to help navigate the daily choices that affect long-term health.

I’m more confident about what I eat, how I train, and which supplements I take. I no longer waste time second-guessing labels or routines. Everything I do now has a reason behind it, backed by a combination of my data and current health science.

If you’re looking for a way to take better control of your health without getting overwhelmed, this kind of system is worth trying. You don’t need to be technical or obsessive. Just gather your information, define your goals, and start asking better questions.

That’s what I did. And for me, it’s made a huge difference. Simple, effective, and completely built around my life.

From Concept to Everyday Life

This is just one example of how I use AI as an assistant in my daily life. I’ve built expert systems for every aspect of my world from finance and investments to health, tech projects, and Geeky Kids itself. Each of these sits as a dedicated project or agent within OpenAI, powered by sophisticated prompts, curated data I upload, and all the knowledge ChatGPT brings through its training. It’s a pretty impressive and practical use of AI and exactly the kind of future-ready thinking we teach.
