The Best Smart Scales for Tracking Weight and Body Composition (2026)

2026年最佳体重与身体成分追踪智能秤

After years of sleepiness, the smart scale world has finally woken up—driven almost certainly by the GLP-1 craze, as millions of consumers find themselves wondering if those weekly jabs are actually working. 在经历了多年的沉寂后，智能秤领域终于苏醒了——这几乎可以肯定是由 GLP-1 热潮所驱动的，因为数以百万计的消费者都在想知道那些每周一次的注射是否真的有效。

What was previously a category occupied by dated gear has abruptly exploded, and for good reason. Today’s smart scales don’t just report on your weight; they do things like measure your heart rate and break down muscle composition, and some can even give you an eye on your heart health, courtesy of technology like integrated ECG systems. Through mobile apps, they can track all of this information over time. 曾经被过时设备所占据的这一品类突然爆发，且理由充分。如今的智能秤不仅能报告体重，还能测量心率并分析肌肉成分，部分产品甚至能通过集成心电图（ECG）系统等技术来监测心脏健康。通过移动应用程序，它们可以长期追踪所有这些信息。

The big shift in the category in the past year has been a flood of new full-body scanners hitting the market from all corners. Essentially bathroom scales with handlebar-based scanners, these don’t just use bioelectrical impedance analysis (BIA) to measure conductivity (and, thus, body fat percentage) through your feet. They can now scan through your hands, too, giving you a much more holistic (and ostensibly accurate) look at your body metrics than a floor scale will provide. 过去一年中，该品类最大的变化是市场上涌现出大量全新的全身扫描仪。这些设备本质上是带有手柄扫描仪的体重秤，它们不仅通过双脚利用生物电阻抗分析（BIA）来测量导电性（进而得出体脂率），现在还能通过双手进行扫描，从而比普通地秤提供更全面（且表面上更准确）的身体指标数据。

I’ve personally seen body fat percentage numbers swing up to 6 percent between the two types of scales. (Spoiler: The full-body scanner data is always higher.) 我个人观察到，这两种秤测出的体脂率数值波动可达 6%。（剧透：全身扫描仪的数据总是更高。）

Do you really need all that information? I’ve long suggested that it’s really the trend line that matters most, not the absolute numbers, and as long as your metrics are headed in the right direction, it doesn’t matter quite as much whether things are off by a small percentage. Consistent weigh-ins are the most important part of the process, along with tracking that information over time to determine whether your diet and workout regimen (or medication routine) is getting you the results you need. 你真的需要所有这些信息吗？我一直认为，真正重要的是趋势线，而不是绝对数值。只要你的指标朝着正确的方向发展，数值偏差几个百分点并不重要。持续称重是整个过程中最关键的部分，同时长期追踪这些信息，以确定你的饮食和锻炼计划（或药物疗程）是否达到了预期的效果。

Mind you, scale prices are headed up, and new full-body scanners can now top $600 for top-tier tech. That’s part of the reason why I still recommend a standard scale for most users, as these devices are considerably less expensive, and the results they offer are likely to be good enough for all but serious athletes. 需要注意的是，秤的价格正在上涨，顶级技术的全身扫描仪价格现在可能超过 600 美元。这也是我仍然向大多数用户推荐标准智能秤的部分原因，因为这些设备价格便宜得多，而且对于除专业运动员以外的绝大多数人来说，它们提供的结果已经足够好了。
