【Latest Trend】Summer Sees Approx. 17% Increase in Gene Testing Kit Usage (Compared to Other Seasons' Average) – Growing Diet Demand Highlights 'Body Type-Focused' Trend

Campingcar Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director and President: Makoto Yorimasa) announced that an analysis of usage data for its gene testing kit, 'Gene Doctor,' revealed an approximately 17% increase in users during the summer season compared to the average of spring, autumn, and winter.

This analysis suggests a rise in demand for efficient results and a growing interest in 'body type-based dieting' alongside the increasing diet demand for summer.

Analysis Overview

Target of Analysis: 'Gene Doctor' user data

Analysis Period: April 2024 - April 2026

Analysis Method: Comparison of seasonal user numbers (Spring, Autumn, Winter average vs. Summer)

Key Findings from the Analysis

The following trends were confirmed from this analysis:

・User numbers increase in the summer season compared to the average of other seasons.

・Usage is concentrated particularly from just before summer into summer (June to August).

・The rise in short-term diet needs may be influencing the increase in usage.

Our company analyzes these results as indicating a strengthening diet-oriented mindset that emphasizes 'efficiency' and 'methods suited to oneself.'

Summer Sees Approx. 17% Increase in Users, Diet Demand Becomes Evident

According to this analysis, the number of 'Gene Doctor' users significantly increased in the summer season, showing an approximately 17% rise compared to the average of spring, autumn, and winter.

Furthermore, a year-on-year increase of approximately 18% was observed, indicating a trend of continuous demand expansion.

Usage peaks particularly in June, making it the month with the highest annual usage. The trend of demand concentrating just before summer became clear.

This is thought to be due to the increasing diet needs driven by a desire for short-term body shape improvement.

Background: Short-term Orientation and 'Time Performance' Emphasis Influence Diet Behavior

Ahead of summer, when lighter clothing is worn, interest in dieting tends to increase from spring to early summer. In recent years, with the spread of a 'time performance' (Tai-pa) mindset that emphasizes cost-effectiveness, there has been a strong need to 'achieve results efficiently without waste.'

On the other hand, in pursuit of short-term results, there are cases where individuals self-diagnose and adopt methods like dietary restrictions or fasting, leading to inefficiencies and risks due to methods not suiting their body type.

・Weight loss not as expected

・Rebounding

・Health deterioration due to stress from restrictions

It is not uncommon to face such failures.

Growing Interest in 'Body Type-Matched' Dieting

Against this background, interest in 'dieting that chooses methods suited to one's body type' has grown in recent years. Individual differences exist in tendencies for fat and carbohydrate metabolism, and ease of muscle gain, which are considered factors causing different results even with the same method.

Our company analyzes from these usage trends that a shift towards dieting that emphasizes 'first knowing one's body type' is progressing.

Gene Testing as One Option for Dieting

Campingcar Co., Ltd.'s 'Gene Doctor' gene testing kit allows for the analysis of individual body type tendencies by collecting saliva.

From the analysis results, it is possible to understand:

・Whether one tends to gain weight from carbohydrates

・Whether one tends to gain weight from fats

・Ease of muscle gain

And receive suggestions for appropriate diet and exercise methods for each. This is expected to enable efficient and sustainable dieting tailored to one's body type, rather than relying on unreasonable restrictions.

Future Outlook

As short-term diet demand for summer increases, the importance of approaches emphasizing 'efficiency' and 'individual optimization' is expected to grow further.

Campingcar Co., Ltd. will continue to support the realization of healthy lifestyles by catering to each individual's body type through gene testing.
