Is ‘Entropy’ the Future of Health Tracking? Deepinder Goyal's Temple Announces New Metabolic Biomarker
Deepinder Goyal has announced "Entropy," a new biomarker from his startup, Temple, designed to measure real-time metabolic expenditure via a temple-mounted sensor. Ranging from 1 to 250, the score aims to replace heart rate as a more precise energy metric. Although early access is available, the technology currently lacks peer-reviewed scientific validation or public technical specifications.
Entrepreneur Deepinder Goyal has introduced a new biomarker named "Entropy", developed by his health-tech startup, Temple, which aims to measure the real-time metabolic cost of human life. According to Goyal, the metric is captured exclusively via a sensor worn on the temple region of the head.
Understanding the Temple's Entropy Metric
Entropy functions as a live digital score, displayed on the Temple platform and updated every second. The index ranges from 1 to 250, with lower values corresponding to deep states of rest, often observed in experienced meditators, and higher values reflecting peak physical exertion, such as that seen in elite athletes.

The company claims this biomarker offers a more precise view of energy expenditure than traditional heart-rate tracking. In internal testing across more than 100 cardio sessions, Temple reported that Entropy correlated with a metabolic cart—a standard laboratory instrument—with a coefficient of r=0.93, significantly outperforming heart rate monitoring, which recorded an r=0.55.
Key Performance Indicators: Entropy Maxima and Minima
- Beyond a singular live reading, Temple has introduced two related benchmarks to help users track their metabolic efficiency:
- Entropy Maxima: This represents the highest level of metabolic output an individual can reach during physical exertion, which the company suggests should be pushed higher to demonstrate a more capable body.
- Entropy Minima: This measures the lowest metabolic state achieved at rest, with the company advising that users aim to reduce this resting cost over time.
- Market Availability and Scientific Scrutiny
While Temple has opened applications for early access to its platform via its website, the company has yet to disclose specific technical details, pricing, or supported hardware devices. Furthermore, the startup has not released any peer-reviewed scientific validation for its claims regarding the biomarker.

The initiative follows earlier discussions surrounding Temple’s experimental focus on monitoring cerebral blood flow. While the startup positions its work as a significant health-tech breakthrough, some industry observers have raised questions regarding the scientific standing of such wearable innovations and the necessity for independent clinical validation before widespread adoption.
