Zomato co-founder Deepinder Goyal's health-tech startup Temple has introduced "Entropy," a trademarked biomarker tracking real-time metabolic cost on a scale of 1 to 250. Worn on the forehead, the device monitors metabolic changes with an r=0.93 correlation to lab calorimeters, outperforming standard heart-rate metrics.
MUMBAI — Neuro-technology and longevity startup Temple has officially unveiled a proprietary health-tracking index branded as "Entropy". Spearheaded by Zomato co-founder Deepinder Goyal, the health-tech venture claims that the newly developed software algorithm accurately measures the body's real-time metabolic expenditure, or the direct "cost of being alive," from a non-invasive wearable device. The disclosure marks a major shift for the food-tech billionaire into deep-tech biomedical research as consumer tech entities scramble to move beyond basic pulse-point calculations.
The 1-to-250 Score: A Micro-Dashboard for Your Metabolism
According to corporate and technical parameters shared by Temple on June 18, 2026, Entropy manifests as a continuous, live numerical score updating second-by-second on the platform's mobile interface. The algorithmic framework translates complex biometric data onto a standardized scale ranging from 1 to 250.
The metric reacts dynamically to a vast spectrum of immediate daily variables that manipulate human metabolism, including nutrient intake, stress fluctuations, caffeine ingestion, deep sleep cycles, strength training, and cold exposure. The startup notes that a score of 1 represents the absolute deepest state of biological rest historically recorded only during fleeting moments in highly experienced meditators while 250 delineates the peak physical output ceiling observed in elite athletes.
Outperforming Traditional Heart Rate Trackers in Lab Benchmarks
A key pillar of Temple’s scientific proposition is that Entropy offers vastly superior accuracy in tracking metabolic burn compared to traditional consumer smartwatches. Goyal revealed that the research team benchmarked Entropy directly against a laboratory-grade metabolic cart (calorimeter) the medical industry's gold standard for calculating exact energy expenditure.
Across more than 100 rigorous cardio training sessions, the Entropy algorithm matched the calorimeter’s actual metabolic curve with an exceptionally high correlation coefficient of r = 0.93 (p < 0.001). In comparison, standard heart rate tracking formulas achieved a low correlation of just r = 0.55, demonstrating that heartbeats per minute remain an imprecise proxy for true instantaneous calorie expenditure.
Dual-Axis Optimization via Minima and Maxima Metrics
To help users systematically gauge their overall physical aging and structural vitality, Temple has accompanied the live score with two supplementary benchmarks: Entropy Minima and Entropy Maxima.
Entropy Maxima: Captures the highest metabolic output an individual can successfully summon under max physical strain. This reflects a body's peak athletic envelope, a ceiling that naturally degrades as humans age.
Entropy Minima: Tracks the lowest operational energy baseline the body drops to during absolute rest. Temple's core research links this to observations in the animal kingdom, where a lower resting metabolic cost correlates tightly with prolonged lifespans, similar to tortoises.
The business operates under Continue Research, a specialized longevity division backed by a massive $54 million seed round from elite venture networks including Peak XV Partners and Info Edge Ventures. While early access registration has crossed over 100,000 requests on the Temple Platform, medical professionals emphasize that the proprietary Entropy index still awaits independent, peer-reviewed clinical validation.

Quote Section
"Heart Rate doesn't come even close to this level of precision in calculating the cost of being alive," executive chairman Deepinder Goyal stated in an official technical brief summarizing the calorimeter benchmark tests.
"According to officials close to the venture's engineering pipeline, the proprietary sensor reads blood flow dynamics non-invasively near the temporal artery, accessing signals unavailable to traditional wristband wearables."
Why It Matters
If peer-reviewed validation confirms Temple's correlation metrics, the feature could revolutionize consumer preventative health by replacing laggy heart-rate approximations with true metabolic tracking. This allows individuals to instantly quantify how specific meals, stress triggers, or workout structures impact their body's biological efficiency and biological aging trajectories.
Key Facts at a Glance
The Biomarker: Temple has developed "Entropy," a real-time metabolic tracking index.
The Scale: The proprietary score reads between 1 (deepest meditation) and 250 (elite athletic flow).
The Accuracy: Logged a near-perfect r=0.93 correlation with gold-standard medical metabolic carts, significantly outperforming heart rate monitoring (r=0.55).
Dual Monitoring: Introduces Maxima and Minima indices to track an individual's performance ceiling and resting metabolic baseline over time.
FAQ Section
How does Temple's device measure the Entropy biomarker?
Unlike conventional wrist-based smartwatches, the Temple wearable is a minimalist device worn on the head. It tracks hemodynamic signals and blood flow non-invasively directly from the temporal artery, which sits close to the central circulatory system.
Can I buy the Temple device and track my Entropy score right now?
Not yet commercially. The startup is presently operating in a controlled beta-testing phase. While early access applications have topped 100,000 entries, only a small cohort of initial users has been cleared for testing, with no official commercial launch date or pricing announced.
Is the scientific data behind the Entropy index peer-reviewed?
No. While internal testing has demonstrated highly accurate tracking curves against clinical calorimeters, the methodology and data algorithms have not yet been published in independent, peer-reviewed medical journals.
