I’d seen somewhere on TikTok that you can upload a selfie to ChatGPT and ask what nonsurgical treatments you could consider. It gives you a full breakdown, like an AI cosmetic surgeon.
Pretty cool, especially given the cost of a cosmetic doctor.
But I’d tested out ChatGPT already for beauty advice and FaceApp to show me how I’ll age. I was looking for advice from AI that went deeper with insights based on my skin and what’s going on underneath its surface. It is the body’s largest organ, after all.
That’s when I discovered Noom’s new AI Face Scan feature, which promises longevity stats from a simple selfie in seconds. I had to try it, even though I was scared about what it would reveal. Years of partying hard and traveling the world likely accelerated my aging process.
Worth it, though.
Noom, a health and longevity platform, launched Face Scan and Future Me in October 2025, available for free to use via the app. Face Scan is powered by NuraLogix, while Future Me uses Haut.ai.
Let’s see my biological age according to AI.
Huberman-style health insights, using AI
To access the AI features, I downloaded the Noom app and created a login. Noom asked a few questions like my age, height, weight and health goals. Once I was set up, I navigated to the Health tab, then selected Health Insights.
I was presented with three options: Face Scan, Future Me and Body Composition Scan.

I was more interested in the health screening report to find out what AI predicted for my biological age, metabolic and heart health indicators and vital signs, as well as what Noom would recommend to improve it. Biological age tests are usually conducted through blood tests, and even then, they aren’t 100% accurate or indicative of overall health.
Selfie time, but do I dare do it without makeup? It’ll probably be more accurate.
Noom opened with its privacy policy, which you have to give consent for, then asked a few more questions, such as my birthday and whether I smoke, take any medications or have diabetes. This information is used for the biological age calculator. I scanned the privacy policy and couldn’t see any red flags.
Then it gave me some tips on how to take the best selfie. Basically, an intense close-up.
While it was loading, it gave more context about how it worked. Noom uses remote photoplethysmography (rPPG) to detect tiny changes in color and light absorption beneath the skin with the aim of determining blood volume and flow, heart rate, breathing and stress levels.
Photoplethysmography is the technology used in wearables, but studies are split on the validity of rPPG.
One study published in 2023 determined it was uncertain as to the extent that rPPG will be able to estimate blood pressure in real-world settings, due to physiologic, environmental and technical limitations. Another study (2021) stated, “image processing based approaches for rPPG have been shown to perform better than contact-based sensors for pulse rate determination.”
Noom has prefaced this in its fine print in the app, stating “Health insights in this report are for informational purposes only and do not constitute medical advice.”
What I saw next was what I feared: a biological age of 44 when I’m 37.
Granted, I took this photo with no makeup while recovering from an IVF procedure a few days ago. Growing up in the Australian sun likely didn’t help, either. According to Noom, it uses the “stress patterns from tiny color changes in the skin.”
Here’s what the report said:
Based on this, the AI app said I should focus on improving my cardiac workload and heart rate variability.
Next up, my metabolic health, which it said was optimal:
Looks like I need to work on the high triglycerides.
Next, I was hoping for a full report with lifestyle suggestions, but it directed me straight to a page to buy GLP-1 — drugs like Ozempic — to “lower my biological age.” Ouch.
This was a bit disappointing because it felt like the endgame was to get me to buy Noom’s products, rather than provide substantive advice.
So instead, I took all this information across to good ol’ ChatGPT for an action plan that I can review and reach out to my doctor about.
Here was my prompt: “I used Noom’s Face Scan feature to learn my biological age and health markers. Can you review the results and provide an action plan on how I can improve my health? I need to improve my cardiac workload and heart rate variability. It said I’m at risk of high triglycerides. Explain what all of this means and what I can do about it to reduce my biological age.”
Reviewing my results
I liked how I could feed all of the information from Noom into ChatGPT for further context. For example, ChatGPT told me the results don’t necessarily mean I’m “unhealthy,” but rather, I have physiological stress markers on the face, possibly due to inflammation and stress. It even said, “recent medical treatments can temporarily worsen bloat/inflammation.”
Thanks, ChatGPT.
Here’s where it got tactical with an action plan to reduce my biological age, improve heart function and lower triglycerides:
It also gave me a 30-day health optimization plan, which included 20-40 minutes of cardio, five minutes of HRV breathing, taking magnesium at night, a 10-minute walk after heavier meals, consuming 30-40g of protein with every meal, drinking 2 liters of water each day, getting morning sunlight and going to bed between 10:30 and 11 p.m. All of that was done daily — it also suggested several times a week of yoga or Pilates, strength training, using a sauna and taking long outdoor walks, as well as recommending a diet that was high in omega-3, low in carbs, low in alcohol, high in fiber and Mediterranean-style.
According to ChatGPT, following these basic tenets would improve my biological age within four to six weeks.
It’s important to note that this is not the same as an accurate medical diagnosis or treatment plan from a qualified clinician — and neither is Noom’s report either — so you should always consult your doctor when you have health concerns or are considering significant changes to your lifestyle (diet, taking supplements, etc.) — especially so that your medical information remains private.
The verdict
While I didn’t love Noom alone, I did find it useful to use those insights to prompt ChatGPT. I’ve ended the year with a big goal for 2026: to get serious about strength training. This reiterates health data I’ve explored with AI before.
Now I have a doable action plan to inform my new year’s goal setting.
