What is Healthy Weight?

Weight is the sum of all tissues such as muscle, bone, fat, and water. It is a comprehensive number that reflects the most basic mass status of your body.

Affected by water, diet, and salt intake, weight can fluctuate significantly within a day. Therefore, a single day's number doesn't prove much. We suggest you focus on the trend of the weekly average, which is more meaningful than obsessing over data from a single weigh-in.

Why are Underweight or Overweight Risky?

Maintaining a reasonable weight range is the first step in preventing chronic diseases:

  • If Overweight: Usually means excessive body fat accumulation, which significantly increases the metabolic burden on high blood pressure, type 2 diabetes, and the cardiovascular system.
  • If Underweight: May indicate insufficient muscle reserves or bone loss. This not only lowers basal metabolism but also increases the risk of future osteoporosis, especially after entering old age, where the probability of falling and fractures will rise.

Comprehensive Assessment

Weight is just one part of the health puzzle. To judge whether your weight is truly "healthy," you can't just look at the size of the number.

In PeakWatch, we suggest you combine BMI, Body Fat Percentage, and Fat-Free Mass (Muscle Reserves) for a comprehensive judgment. Only when these indicators are all within a reasonable range is your weight truly high-quality healthy weight.
