Most nutrition advice is generic by necessity. Levels is built around a simpler idea: your body's response to food is not generic, so the feedback shouldn't be either.
Levels is a metabolic health app that combines meal logging, wearable integrations, and — for members who add it — a continuous glucose monitor (CGM) to show, in near real time, how specific meals, workouts, sleep, and stress move your glucose. It layers a proprietary Metabolic Score on top of that data so a spike in a chart becomes a simple number you can act on.
It is not cheap once you add sensors, it is not a diagnostic tool, and it is not necessary for everyone. But for people who already track their training and sleep and want to close the loop on nutrition, it can turn abstract "eat healthier" advice into something concrete and personal.
The LuxeWell position: Levels will not fix a bad diet by itself. But if you have ever wondered which of your "healthy" meals are quietly working against you, it answers that question with more precision than almost anything else available direct-to-consumer.
Quick Verdict: Is Levels Worth It?
Yes — for the right person. Levels is worth it if you want personalized, immediate feedback on how food affects your body and you are willing to pay for a recurring membership plus sensor costs to get it.
The strongest reason to try Levels is not the app polish or the AI-generated insights. It is the Metabolic Score — the ability to see, meal by meal, whether a specific choice worked for your body or quietly worked against it.
If you already treat sleep and training as performance levers and have never had a clear way to test nutrition the same way, Levels can feel instantly valuable. If you just want general "eat better" guidance, it is more tool than most people need.

What Is Levels?
Levels is a metabolic health company built around one central idea: nutrition advice is generic, but your body isn't. Instead of another meal-tracking app that counts calories in isolation, Levels layers your food log, your wearable data, and — when you add it — real-time glucose data into one system designed to show you what actually works for you.
You can start with the app alone, connect an existing CGM, or get a sensor through Levels' telehealth partner network. From there, the platform can add lab testing, biomarker tracking, and clinician or dietitian support as you go deeper. It is built as a system you can start small with and expand, not an all-or-nothing purchase.
The core idea is simple: two people can eat the "same" healthy meal and have very different glucose responses. Levels automates the process of noticing that difference and translating it into a Metabolic Score and specific next-step guidance, instead of leaving you to guess from a generic nutrition chart.
The company's medical advisory board includes names readers of longevity content will recognize, including metabolic health researchers and authors like Dr. Ben Bikman and Dr. Rob Lustig, and its coverage in outlets like the WSJ, NYT, and Men's Health reflects its position as one of the earliest and best-known players in consumer CGM.
The Features That Matter Most
Metabolic Score
Every logged meal gets a 1–10 score based on how your glucose actually responded, turning a chart into a simple, repeatable signal.
Continuous glucose monitoring
Optional CGM sensors (Dexcom Stelo, Dexcom G7, or Abbott FreeStyle Libre 3) track glucose around the clock, not just at a single fingerstick moment.
Flexible meal logging
Log meals by text, photo, or barcode, with macro breakdowns and food-quality feedback built in.
AI health insights
Adaptive programs surface patterns like "your glucose runs higher on days with under seven hours of sleep" automatically.
Wearable and lab integration
Connects with Apple Health and wearables like Oura and WHOOP, plus lets you upload past bloodwork and biomarker panels into one view.
Guided programs
Structured paths for goals such as glucose control, heart health, and weight management for members who want more direction than raw data alone.
How Levels Actually Works, Day to Day
Most new members start with a short quiz that recommends a starting plan based on your goals, budget, and whether you already own a CGM or wearables. From there, the day-to-day rhythm looks similar across plans, just with more or less glucose data layered in.
1. Take the quiz
A short intake recommends Build, Core, or Complete based on your goals and current setup.
2. Log meals and habits
Text, photo, or barcode logging feeds macro and food-quality feedback from day one, even without a sensor.
3. Wear a sensor (optional)
CGM plans include a telehealth prescription and sensor shipment; most sensors are worn for roughly 10–14 days per cycle.
4. Review patterns
The app correlates glucose with meals, workouts, sleep, and stress, and the AI insights layer flags what to try next.
Levels Pricing and Plans
Levels is structured as three entry points rather than one fixed price, so the "real" cost depends heavily on which plan you choose and how many sensor cycles you use per year. All plans are HSA/FSA eligible.
| Plan | Price | What's Included |
|---|---|---|
| Build your system | $15/mo ($80 billed annually) |
App, food logging, AI health insights, adaptive programs, wearable data import, past bloodwork uploads. Glucose monitoring, labs, and dietitian support are optional add-ons. |
| Core (recommended) | $41/mo ($499 billed annually) |
Everything in Build, plus 2 essential lab panels (28+ markers), 1 month of continuous glucose monitoring, and clinician review of your data twice a year. |
| Complete | $167/mo ($1,999 billed annually) |
Everything in Core, plus 2 comprehensive lab panels (100+ markers), 2 months of CGM with free shipping, a 50-minute functional nutritionist session, and dedicated concierge support. |
Pricing shown reflects Levels' published rates as of August 2026 and can change. Sensors beyond what's included in a plan, additional lab panels, and extra dietitian sessions are available as add-ons at additional cost. Always verify current terms directly with Levels before purchasing.
Value rule: Build is a reasonable way to try the app and habit tracking cheaply. The real value proposition of Levels — seeing your own glucose curve — only shows up once you add CGM through Core, Complete, or an add-on sensor. Signing up through the link in this article adds 2 free months to any annual plan, which meaningfully improves the math on Core or Complete.
Why Glucose Data Matters, Even Without Diabetes
Glucose monitoring has traditionally been a diabetes-management tool, checked with occasional fingersticks. A CGM changes the resolution entirely — instead of a handful of snapshots, you get a continuous curve that shows exactly how a specific meal, workout, or short night of sleep moved your glucose, in the moment it happened.
That resolution is what makes the feedback feel personal rather than generic. Two "healthy" breakfasts — say, oatmeal versus eggs and avocado — can produce very different glucose curves depending on your own biology, and a CGM is one of the few ways to actually see that difference instead of guessing from a nutrition label.
For non-diabetic users, this is framed as a wellness and awareness tool rather than a diagnostic one. Levels is explicit that its products are meant to support a healthy lifestyle and are not intended to diagnose, treat, cure, or prevent any disease, and should never be used for medication or insulin dosing decisions.
Evidence context: Large, long-term randomized trials on CGM use in healthy, non-diabetic adults are still limited, and current diabetes-care guidelines focus CGM recommendations on people already being treated for diabetes. Levels' own reported outcomes are drawn from retrospective analysis of its member base, not a controlled clinical trial — useful signal, but not the same as peer-reviewed proof.
What the Data Shows: Reported Member Results
Levels publishes retrospective outcome data pulled from its own member base. It is worth reading as directional evidence from a large, real-world population rather than as a clinical trial, since there is no control group and no peer review.
Figures reflect members who started outside optimal ranges (e.g., HbA1c improvements among members who began in the prediabetes range). Based on retrospective analysis of the Levels member population, not a clinical trial. Individual results will vary and should not be read as a guarantee.
The Metabolic Score: Levels' Best Feature
Raw glucose charts are useful, but most people do not want to interpret a squiggly line after every meal. The Metabolic Score compresses that curve into a single 1–10 number per meal, based on how high your glucose rose and how quickly it came back down.
In practice, this is what makes Levels stick for people who try it. A bowl of white rice might score a 3. Swap in cauliflower rice with the same protein, and the same meal might score an 8. That kind of immediate, personalized comparison is a faster teacher than most nutrition guidance, because it is specific to your own body rather than a population average.
The tradeoff is that the scoring algorithm is proprietary and not independently peer-reviewed, so it should be treated as a helpful directional signal — not a clinical-grade metric.
Best use case: someone who already logs training and sleep, eats what they'd call a "healthy" diet, and wants to find the specific foods that are quietly working against their energy, cravings, or focus.
CGM Sensors and Wearable Integration
Levels does not manufacture its own sensor hardware. Instead, it supports Dexcom Stelo, Dexcom G7, and Abbott FreeStyle Libre 3, and lets you connect a sensor you already have or get one prescribed through its telehealth partner network as part of a plan.
That software-layer approach is Levels' real differentiator. Owning a raw CGM sensor gives you a glucose number; Levels' value is in the app layer on top — the Metabolic Score, the AI-generated pattern insights, and the ability to see glucose alongside sleep, workouts, and stress in one view.
On the wearable side, Levels connects with Apple Health and platforms like Oura and WHOOP, so if you already track sleep and recovery, that data can feed directly into your metabolic insights instead of living in a separate app.
| Feature | Levels | Raw CGM alone (e.g., Dexcom Stelo direct) |
|---|---|---|
| Glucose data | Yes | Yes |
| Per-meal scoring | Yes | No |
| Wearable + sleep integration | Yes | No |
| Lab and biomarker tracking | On Core/Complete | No |
| Ongoing cost | Membership + sensor | Sensor only, lower cost |
Getting Started and Daily Use
Onboarding has a bit more friction than a typical app download because CGM sensors are prescription devices in the U.S. After picking a plan, CGM members go through a telehealth intake with Levels' partner network before a sensor ships. That step is quick for most people, but it is a real gate, not a formality.
Once a sensor arrives, applying it takes a few minutes and it is worn on the back of the upper arm, generally water-resistant enough for showers and swimming. Most sensor cycles last roughly 10–14 days, after which higher-tier plans include additional sensor months and Build-plan members can add sensors separately.
Day to day, the main habit is logging meals — by text, photo, or barcode — and occasionally checking in on the glucose chart and AI insights. Between sensor cycles, the app still works for meal logging and habit tracking, so the experience does not simply stop when a sensor runs out.
Practical note: if you dislike wearing a device on your arm, do not want a telehealth step in your onboarding, or are not willing to log meals consistently, the CGM tiers of Levels will feel like more friction than value.

- Optional labs and clinician review let you go deeper without switching platforms
What we do not like
- Full CGM experience adds real, recurring sensor costs on top of membership
- Requires wearing a sensor on your arm to unlock the core value
- Not a diagnostic tool and not intended to manage diabetes or medication dosing
- Long-term outcome evidence in non-diabetic users is still emerging
- Metabolic Score algorithm is proprietary and not independently peer-reviewed
- Telehealth prescription step adds friction to onboarding
Levels Alternatives
Levels is not the only metabolic health platform built around CGM data, and it is not always the cheapest. The right alternative depends on how much you want a human coach involved versus a self-serve, data-first experience.
| Alternative | Best For | Compared With Levels |
|---|---|---|
| Nutrisense | People who want 1:1 support from a registered dietitian | Similar CGM-based data with more built-in human coaching; Levels leans more self-serve and AI-driven |
| January AI | Predictive glucose insights without always wearing a sensor | Can estimate glucose response from food photos alone; Levels' Metabolic Score is more precise once you add a real sensor |
| Signos | Weight-management-focused CGM users | More narrowly weight-loss-oriented; Levels covers a broader set of metabolic and longevity goals |
| Dexcom Stelo (direct) | Buyers who just want raw glucose numbers cheaply | Lower ongoing cost but no Metabolic Score, meal logging, or wearable integration layer |
| Function Health | Broad biomarker and lab-panel tracking over time | Deeper lab coverage but no continuous glucose monitoring; better paired with Levels than used instead of it |
Who Should Buy Levels?
Longevity-focused optimizers
If you already invest in sleep and recovery tracking, Levels closes the nutrition gap in your data.
People with prediabetes or insulin resistance concerns
Under a doctor's guidance, real-time glucose data can make dietary changes feel far more concrete.
Data-driven biohackers
If you like closed feedback loops and A/B testing your own habits, this is built for you.
Anyone overwhelmed by generic advice
If "eat clean" advice has never quite worked, personalized glucose data can explain why.
Weight-management-focused users
Seeing which foods spike glucose and appetite can make sustainable changes easier to stick to.
Wearable enthusiasts
If you already use Oura, WHOOP, or Apple Health, Levels adds the missing nutrition layer.
Who Should Skip It?
Skip Levels if your budget is tight, you are not willing to wear a sensor on your arm, or you are mainly looking for a diagnostic tool — Levels is explicitly not intended to diagnose, treat, or manage any medical condition.
It is also not the right fit if you know you won't act on the data. The Metabolic Score is only useful if you are willing to actually log meals and adjust based on what you see; without that follow-through, the sensor cost is hard to justify.
If you have diagnosed diabetes or another condition that requires glucose monitoring for treatment, that should be managed with your healthcare provider and a clinical-grade monitoring plan — not primarily through a wellness app.
Frequently Asked Questions
What is Levels and how does it work?
Levels is a metabolic health app that connects meal logging, wearable data, and optional continuous glucose monitoring (CGM) to show you how food and lifestyle choices affect your body in real time. It rates meals with a proprietary Metabolic Score and turns patterns in your data into guidance.
Do I need a prescription for the Levels CGM sensor?
Yes. In the U.S., continuous glucose monitors are prescription devices. Levels handles this through a telehealth partner as part of signup, so you do not need to arrange a prescription with your own doctor first.
Which CGM sensors work with Levels?
Levels supports Dexcom Stelo, Dexcom G7, and Abbott FreeStyle Libre 3 sensors. You can get a sensor through Levels or connect one you already have.
How much does Levels cost?
Levels offers three starting points: Build your system at roughly $15/month, Core at roughly $41/month with essential labs and one month of CGM included, and Complete at roughly $167/month with comprehensive labs, extended CGM, and concierge support. Pricing is lower when billed annually, and sensors beyond the included allocation cost extra.
Is Levels worth it if I don't have diabetes?
It can be, for the right person. Levels is built for generally healthy adults who want to understand their own glucose response to food, not as a diabetes management tool. If you mainly want personalized, immediate feedback on nutrition choices, it can be a genuinely useful lens even without a metabolic diagnosis.
Can Levels diagnose diabetes or prediabetes?
No. Levels is intended to support a healthy lifestyle, not to diagnose, treat, cure, or prevent any disease, and it should not be used for medication or insulin dosing decisions. Talk to a healthcare provider about diagnosis and treatment.
What's the difference between the Build, Core, and Complete plans?
Build is the app-only entry point, with glucose monitoring, labs, and dietitian support available as optional add-ons. Core bundles one month of CGM with essential lab panels and biannual clinician review. Complete adds comprehensive labs, extended CGM with free shipping, a nutritionist session, and dedicated concierge support.
Does Levels work with my other health devices?
Yes. Levels connects with Apple Health and wearables such as Oura and WHOOP, and lets you upload past bloodwork so your glucose, sleep, activity, and lab data live in one place.
The LuxeWell Edit Verdict
Levels is not cheap once you add sensors, it is not a diagnostic tool, and it will not fix a bad diet on its own. It is also one of the more genuinely useful ways to replace generic nutrition advice with feedback specific to your own body.
Buy it if you already track sleep and training, want personalized rather than generic nutrition guidance, and are comfortable paying for a membership plus sensor costs to get it.
Skip it if you are budget-constrained, unwilling to wear a sensor, or looking for a diagnostic tool rather than a wellness and awareness platform.
Our final take: for data-driven optimizers who have never had a clear way to test nutrition the way they test training, Levels is one of the more compelling metabolic health tools available direct-to-consumer.
