Following sharp criticism from medical professionals regarding the wearable device Temple, startup founder and former Eternal CEO Deepinder Goyal spoke out on Friday to clarify that the gadget functions strictly as a fitness tracker and wellness device. He assured the public that rigorous scientific validation and independent studies will be shared as soon as the product reaches users.

In a series of posts on the social media platform X, Goyal explained that customers will be able to test the device's claims firsthand once it is delivered. He highlighted that the company has instituted a 14-day return policy, allowing users to return the device without any questions asked if they are unsatisfied.

Detailing the financial backing behind the project, he noted that Temple has consumed an investment of approximately 30 million dollars, which includes nearly 20 million dollars of his own capital. He argued that such a substantial financial stake and long-term commitment completely invalidate any suggestions that the product is fraudulent.

Goyal stepped down from his role as Eternal's CEO specifically to focus on Temple, emphasizing that his personal reputation is directly tied to the scientific accuracy behind the product.

He candidly admitted that Temple has not yet completed the clinical verification for all of its metrics, adding that the company will release this information as soon as such verification becomes officially available.

## Fitness Tracker Versus Medical Device
Reiterating the device's core purpose, Goyal stated that Temple is a fitness tracker and wellness device rather than a medical tool. He added that further scientific validation and independent studies will emerge as the product becomes widely accessible to users.

These remarks follow a wave of growing criticism from medical experts, most notably led by hepatologist Cyriac Abby Philips, widely known online as The Liver Doc.

Philips has publicly challenged the scientific validity of Temple, specifically questioning its ability to measure brain-related metrics through the superficial temporal artery. In multiple posts on X, Philips alleged that the company has failed to provide sufficient evidence supporting its claims regarding cerebral blood flow and other complex physiological parameters.

He argued that the currently available public materials and pre-print research papers fall short of fully substantiating the device's capabilities, accusing the firm of exaggerating the science behind its product.

## The Broader Debate Over Scientific Evidence
Critics maintain that independent peer-reviewed evidence must be presented before such health-related claims can be accepted by the public. They argue that consumer wellness gadgets require stringent validation standards.

In response, Goyal maintained that Temple will continue publishing its validation data moving forward and stands firmly behind its scientific methodology. This ongoing discourse has sparked a major online debate regarding the exact level of scientific proof consumer wellness gadgets should provide before making health claims.

## What this means for you
This high-profile dispute directly affects consumers who are considering purchasing new health and fitness wearable gadgets.

- **Across India:** Everyday consumers must now examine health gadget advertisements and scientific claims with greater caution. Buyers should wait for independent studies and clinical verification before investing money in emerging wellness technology.
- **For Buyers:** The company's 14-day return policy gives early adopters a risk-free opportunity to test the device themselves. If the gadget fails to meet expectations, users can secure a complete refund without facing complex questions.
- **Market Impact:** The ongoing debate places intense pressure on Indian health-tech startups to provide rigorous scientific proof for their marketing claims. Regulatory bodies and health watchdogs may tighten oversight on consumer wellness products moving forward.
- **Medical Sector:** The friction between medical professionals and startup founders highlights the need to clearly separate consumer wellness devices from actual medical equipment. This clash could lead to stricter industry guidelines for tech-enabled health tools in the future.

## Why this happened
This controversy was triggered by a direct clash between ambitious marketing claims made by a startup and the rigorous scientific standards demanded by the medical community.

- **Lack of Verification:** The primary catalyst is that the Temple device has not yet completed or published full clinical verification and independent peer-reviewed data for all of its metrics.
- **Physiological Skepticism:** Medical experts questioned the technological plausibility of accurately measuring cerebral blood flow through the superficial temporal artery using a consumer wearable.
- **Regulatory Concerns:** Doctors argue that marketing health-related consumer wellness products without robust medical validation sets a concerning precedent for public safety and consumer trust.
