Daiso Weight Scale InBody — From 5,000 won product specifications to comparisons with public health centers

Many people weigh themselves every day at home but have no idea whether they're actually losing body fat. Now that word's been spreading about Daiso selling a 5,000-won InBody scale, I've been getting more and more questions like "Doctor, is this one enough?" I hear this question almost every week in the clinic too.

Why the Daiso InBody Scale Is Popular

The Daiso body composition scale has product number 1056372 and costs 5,000 won. This is the product everyone calls the "Daiso InBody." It doesn't just weigh you—it displays body weight, BMI, body fat mass, body fat percentage, skeletal muscle mass, muscle mass, body water content, visceral fat index, and basal metabolic rate (BMR) all at once.

The measurement range goes up to 180kg, displayed in 50g increments. It operates with 2 AAA batteries, and when you install the dedicated app (OKOK / O'KOK International), measurements are automatically recorded via Bluetooth connection and graphs can be generated. The ability to register and manage multiple family members separately is another feature that people just starting a diet really appreciate.

For 5,000 won, the specs are quite generous. I completely understand the temptation to think "So I don't need to go to the public health center for an InBody—I can just use this instead?"

Accuracy Compared to Public Health Center InBody

This is probably what you're most curious about. Among actual user reviews, there are cases where people measured themselves on the Daiso scale and the public health center's InBody equipment on the same day.

• Weight: Many reviews say that both devices showed similar values.
• Body Water: Daiso 38.2kg, Public Health Center InBody 35.4kg. There was a difference of about 2.8kg.
• Muscle Mass: Daiso 50.1kg vs Public Health Center 45.5kg. A difference of about 4.6kg.
• Skeletal Muscle Mass: Daiso 25.9kg vs Public Health Center 26.7kg, which were relatively closer.

While weight can be trusted to some extent, it is safer to view body composition figures such as body fat, muscle mass, and water content as "for reference" rather than absolute values. There are frequent instances where muscle mass increases by 1kg one day and decreases the next; in most cases, this is due to slight changes in measurement conditions rather than actual changes in the body.

What is different about the home-use InBody Dial?

"InBody" is a company name. The large equipment found in gyms or public health centers are also products from the same company. The home-use InBody Dial series (H20·H30·H40) is a scaled-down version of that technology for easy home use. Only products with the InBody logo are official lines of InBody Co., Ltd.; most other products called "InBody scales" are actually body composition scales made by other companies.

Although there are differences between models in the Dial series, they basically measure weight, body fat percentage, muscle mass, and visceral fat. When linked with the InBody app, you can also check Body Mass Index (BMI), waist-hip ratio, body water, protein, minerals, basal metabolic rate, and body type coordinates. While the price range is much higher than Daiso products, this is the line preferred by those who want values closer to the equipment at public health centers.

The selection criteria are surprisingly simple: "Can you go to the public health center 1 time a week, or do you want to measure every day at home?" For those who find the act of daily measurement motivating, getting a device—whether it's from Daiso or the InBody Dial—will be helpful.## Perspective from Baekrokdam Korean Medicine Clinic — Direction of Change Matters More Than Numbers

When I look at InBody results together with patients in the consultation room, there's something I always emphasize. The "trend" measured on the same device under the same conditions is far more important than the number itself.

In traditional Korean medicine, weight loss is not viewed solely as how many kilograms of fat were lost. We also look at whether swelling tends to decrease well for your body constitution, whether muscles are being adequately supported, and whether appetite patterns have stabilized. I often see patients who check their Daiso scale every day and get upset over the numbers. They'll gain 1kg one day due to water retention, then lose it the next day and interpret it as "I lost weight because I didn't eat yesterday."

Especially during the first 1week of dieting, patients who rapidly lose 5~7kg are almost always in the phase where body water is being cleared first. True body fat changes come gradually after that. That's why I guide patients taking herbal medicine to "weigh yourself 1 time(s) per week, on the same day, at the same time."

Small Habits to Improve Measurement Accuracy

Even with the same Daiso scale, how you measure can cause the numbers to fluctuate. We accept that there's a limit to accuracy, but we can reduce the range of fluctuation.

• Weigh yourself first thing in the morning after using the bathroom, on an empty stomach.
• Wipe your feet so there's no moisture where they contact the electrodes, then step on the scale.
• Weigh yourself about 3 times on the same day and at the same time each week, and take the average to reduce erratic fluctuations.
• Don't weigh yourself right after exercise or right after a sauna. Muscle mass can appear distorted because water has been lost.
• If your basal metabolic rate (BMR) shows as 1496kcal, don't take it as an absolute value—use it only as a reference to get a sense of "this is where I stand relative to my usual activity level."

Action Points — Things You Can Do Right Now

Let me organize some things you can start changing from today.

• A Daiso body scale can be used daily, but only log results 1 times per week. If you record every day, it's easy to get thrown off by fluctuating noise.
• Measure your waist circumference with a tape measure along with your weight. Even when body fat percentage fluctuates, waist circumference is quite reliable.
• Once a month, get checked with a public health center InBody to calibrate your home scale's error direction. You'll develop a sense like, "Ah, mine tends to overestimate muscle mass by about 4 kg."
• When weight plateaus, don't cut your diet further just based on Daiso scale readings. When muscle decreases, your basal metabolic rate drops as well.

If a Daiso body scale is around 5,000 won and has this level of specs, it's a genuinely useful tool. However, a tool is just a tool—those numbers don't tell you everything about your body. Building a habit of measuring at the same time every day and just observing the direction of change makes a much bigger difference. If you find yourself frustrated because InBody numbers keep plateauing, or if edema and body water fluctuations are so large that you can't see real changes at this stage, another option is to work on aligning your body constitution together with the herbal weight management program Baekrok Gambi-jung (tablet). We can look at the graphs together in the clinic and design your next month.
