Deepinder Goyal unveils Entropy biomarker to track metabolism in real time

MUMBAI: Life may be full of ups and downs, but Deepinder Goyal now wants to measure every one of them second by second. The Zomato co-founder has unveiled a new health-tech concept through his venture Temple, introducing a biomarker called “Entropy” that he says can track the body’s real-time metabolic cost. Positioned as a live measure of how much energy the body is expending at any given moment, the metric aims to provide a continuous view of human metabolism rather than relying on periodic health indicators.

Goyal described Entropy as a way to quantify the “real-time cost of being alive”. Unlike traditional health metrics that offer occasional snapshots, Entropy is designed to update every second, creating a constantly evolving picture of the body’s metabolic state.

The score operates on a scale of 1 to 250, where lower values indicate deeper states of rest and recovery, while higher readings correspond to intense physical exertion and heightened energy expenditure.

What makes the concept particularly intriguing is where the data is collected. Temple claims the biomarker can be measured through the temple region of the head, allowing continuous monitoring of metabolic activity throughout the day.

According to Goyal, the system dynamically responds to a broad range of everyday factors that influence metabolism. Everything from sleep, stress and exercise to meals, caffeine intake, meditation, cold exposure and strength training can alter the score in real time, offering users a minute-by-minute understanding of how their lifestyle choices impact their bodies.

Temple further claims that Entropy may offer a more accurate representation of metabolic activity than traditional indicators such as heart rate. Goyal said the company benchmarked the metric against readings from a metabolic cart, a laboratory-grade instrument used to measure energy expenditure as part of its validation efforts.

The data emerging from early observations has produced some notable results. According to Goyal, the lowest Entropy scores have been recorded among experienced meditators during deep meditation, while the highest readings have been observed in elite athletes operating at peak performance levels.

The announcement reflects the broader trend of health technology moving beyond simple fitness tracking towards deeper physiological measurement. As wearable devices and biometric tools become increasingly sophisticated, companies are racing to create new metrics that promise a more comprehensive understanding of human health.

However, questions remain. Temple has yet to publish detailed technical documentation or disclose the precise methodology used to calculate Entropy. As a result, the biomarker’s scientific validity and accuracy have not yet been independently verified by external researchers.

For now, Entropy sits somewhere between a promising breakthrough and an intriguing experiment. What is clear is that Goyal’s latest venture is betting that the future of health monitoring lies not just in counting steps or tracking heartbeats, but in decoding the body’s energy economy in real time.

The announcement was made through a post on X, where Goyal also invited users to apply for early access to the platform as Temple begins testing its new approach to metabolic tracking.
