“Why can’t I lose weight as easily now that I’m in my forties?” “Am I perimenopausal?” “Why is my sleep hygiene so bad?” “Why do I have inflammation?”
No, I’m not having a mid-life crisis. These are just some of the questions I’ve been bombarding ChatGPT with regarding my health lately. One could say I’m “prompting with purpose,” trying to decode the mysteries of vigor and vitality in this new decade. As more things seem to fall apart—one wrong move and there goes a knee—I realise I’ve never been so health conscious as I am now. To put it aptly: I’m in my healthmaxxing era. What is healthmaxxing, exactly? Well, according to ChatGPT, “it is a modern internet term derived from ‘maximising’ that means optimising your health as much as possible across all areas of life—nutrition, sleep, fitness, hormones, mental health, and longevity.” It’s not just simply about being healthy per se, but rather “systematically upgrading your biology and lifestyle.”
To do exactly that, I embarked on a personalised seven-day reset program designed by AI. It promised a science-based, sustainable to-do list that was tailored to focus on my goals of fat loss, lowering cortisol, reducing inflammation, and improving energy without pushing my body into stress overload. All that without making a single phone call or scheduling any appointment.
And regarding those incessant questions, turns out I’m not the only one. In Singapore, during the first week of January 2026 alone, over 2.6 million messages related to goal setting, fitness, and nutrition were sent to ChatGPT. Seems like it might not just be a “getting older thing”, but a world movement thing. This sector is big business now, with Global Wellness Institute reporting that the world wellness economy has reached a record 6.8 trillion dollars, and is forecast to hit 9.8 trillion dollars by 2029, up 35 percent since 2019.
“The reality is, many people do not struggle with knowing what to do; they struggle with doing it consistently when life gets busy, energy dips, or motivation fades. The reset was meant to help reduce that friction.”
According to Grace Chua, Head of Communications for Southeast Asia at OpenAI, this area is already one of the most common use cases for the tool globally, with more than 230 million people worldwide asking health and wellness related questions on ChatGPT each week. With a significant uptick in target setting and personal coaching prompts (up 40 percent) and fitness and exercise queries (up 21 percent) in January 2026 compared to December 2025, Chua postulates that “people are looking for practical, personalised ways to follow through on their goals. It’s less about consuming information and more about turning intention into action.”
While it is best used for education, structure and support and an easy, digestible way for people to “understand information, build routines that feel realistic, and make day to day decisions that feel more manageable,” she adds a necessary caveat: ChatGPT is a tool for structure and support, but “it is not a substitute for professional medical advice, diagnosis, or treatment.”
The seven-day strategy
They say it takes 21 days to form a habit, so why seven? Chua explains the idea was conceived after a wellness event in Singapore earlier this year, inspired by one of the top five local use cases—engaging ChatGPT for practical guidance and how-tos. Attendees felt they needed assistance and or inspiration on selecting healthier meal options, creating realistic post-work workout plans, or figuring out how to sleep earlier without staring at their devices till midnight. All very relatable queries. “The reality is, many people do not struggle with knowing what to do; they struggle with doing it consistently when life gets busy, energy dips, or motivation fades. The reset was meant to help reduce that friction.” In short, it’s more of a starter-kit to help enhance current routines or find preferable alternatives to build healthier habits.
So with that in mind, and leading a sometimes intense lifestyle myself as a working mother of two young children, I decided it couldn’t hurt to fine-tune a few things, based on an AI analysis. The appeal of “immediacy and accessibility” benefits Chua describes certainly seemed very low pressure and straightforward. To benchmark my experience, I recruited another forty-something, busy working participant, Yi Lian Ng-Groves, founder of Aweness and Yi Lian Ng Floral Atelier and consulted a qualified Nutritional Therapy Practitioner (NTP), Karmen Tang, founder of Good For You. The latter bridging the gap between the algorithm and the physiological reality of a seven-day reset.
For my reset, it all started with the prompts. I asked ChatGPT to “act as a nutritionist, endocrinologist, and lifestyle medicine advisor” and to “design a personalised seven-day reset program,” using my various profile metrics age, height, weight, activity level, sleep patterns, and stress levels. I also asked it to design a sustainable program that included a daily schedule, anti-inflammatory meals and snacks with simple recipes, workouts that support fat loss without increasing cortisol excessively, sleep optimisation habits, foods to avoid for hormone balance and inflammation. It rapidly generated a step-by-step guide covering morning, noon, and night, including anti-inflammatory meal plans and “cortisol-conscious” workouts. Turkey, lettuce wraps, five minute breathing sets and avoiding excess HIIT workouts? Seemed easy enough.
The expert take
For Tang, who is deeply ingrained in the traditional health and wellness sphere, she observes in recent times that “nutrition is shifting away from short-term dieting and towards outcomes people can feel and sustain,” like for instance better sleep, calmer digestion, steadier energy, improved focus, and so on. Adding that people are less interested in a single “fix,” and rather is seeing “a growing interest in nervous system regulation, because people are realising that you can’t “out-supplement” chronic stress and poor sleep.” And finally, she’s also noticed that “ingredient literacy is rising,” with more people questioning food brands and labels, using Large Language Models (LLMs) as a tool simplify confusing ingredient lists.
“Nutrition is shifting away from short-term dieting and towards outcomes people can feel and sustain.”
What impressed Tang most about the AI’s reset was its focus on fundamentals—protein, fiber, and sleep hygiene—rather than dramatic restriction. In essence, a return to the basics from the algorithymic side, and a consistency and prioritisation from the user to maximise results. From a NTP perspective, she says that actually seven days is a “useful window to stabilise blood sugar swings, establish more consistent meal timing, and reduce the noise from ultra-processed foods and alcohol. It can also highlight patterns quickly, like how caffeine timing affects sleep, or how low-protein mornings lead to afternoon crashes.” It’s enough time to create momentum and should be perceived more as a “diagnostic week” or “structured starting point”, with overall metabolic improvement more a longer term game. For a more tailored approach, Tang suggests including recent blood tests or gut health results into the prompts, and to pressure-test the recommendations, rather than treat them as medical advice.
Man vs. machine
I would tend to agree—the ChatGPT suggestions are super easy to take in, but a lot of it simply comes down to self motivation and following through—from prompt to physicality. Obviously there is also an element of neutrality when it comes to AI in that there is no dietician or personal trainer casting judgement. Tang highlights “neutrality can reduce shame and make it easier to start, especially if someone feels intimidated by wellness culture.” Ng-Groves elucidates, “at the end of the day, if you’re motivated or not, it doesn’t really matter whether it’s a human helping you or a machine. If you’re motivated, you’ll just find ways to get certain things done.”
In Ng-Groves’ opinion, seven days is certainly enough time to identify what’s possible and what’s not. Overall does she find AI a trustworthy source of information when it comes to her personal wellbeing? Ultimately, yes. “Being a human being with common sense, we can discern what it’s telling us and not take the information wholesale. AI combs through your history to give tailored advice at a super-fast speed, versus how we used to have to research bit by bit for the different information we need.” Her favourite part of using AI? That it can be customised pretty well to each individual.
As for me: Did I follow the reset to an absolute tee? No. Did I have a little sweet treat and a little doomscroll before bed? Guilty. Was there anything suggested that was surprising or groundbreaking? No. Was it easy to follow and completely doable? Yes. Overall I saw the AI intervention as more of a circuit breaker of habits, or even a reframing of how I was approaching my wellness—a road map to improvement, if you will. Plus, we don’t always have the time or resources for in person consultations, personal training sessions, or even planning our meals. This is where AI can fill a void. At the end of the day, it all still comes down to you, the human. But including suggestions by LLMs with our busy lifestyles is probably the best approach. Tang says “without a relationship and accountability, it can be easier to disengage, rationalise, or cherry-pick advice. In practice, the best results come when people use AI as support, but still have human accountability through a practitioner, community, or a clear system they can stick to.”
“At the end of the day, if you’re motivated or not, it doesn’t really matter whether it’s a human helping you or a machine.”
In terms of moving from reset to routine? Chua argues that a reset can “serve as a low-pressure entry point, but routine comes from iteration: reviewing what worked, identifying what did not, and adapting the plan until it realistically fits into one’s schedule.” One thing I realised through this experience is that small incremental change can lead to exponential outcomes. Working in tandem with AI for support, while putting in the work can really lead to real results.
