For a 170cm female, a healthy weight generally falls between 54 kg to 72 kg (119-159 lbs), with averages around 55-68 kg, but this varies greatly by body frame, composition, and age, with some calculators suggesting ideal weights like 61-62 kg. The Body Mass Index (BMI) range for this height is approximately 18.5-24, translating to roughly 54-69 kg.
So. Ideal body weight for someone with 170 cm height is 60 kg.
Convert your height from centimeters to meters (e.g., 170 cm = 1.7 m). Square your height in meters (1.7 m × 1.7 m = 2.89 m²). Divide your weight in kilograms by the squared height in meters (e.g., 70 kg ÷ 2.89 m² = 24.2 BMI).

An example is shown for an individual who weighs 80 kg (176 lbs) and stands 1.75 meters (175 cm or 69 inches) tall. Those measurements put that individual into the "overweight" category.
Using the example of a female who is 170 centimeters tall, their estimated ideal weight would be 170 - 105 = 65 kilograms.
"Chubby" isn't a medical term, but it generally refers to being in the Overweight BMI category (25.0 - 29.9 kg/m²) or starting to enter the Obese range (30+ kg/m²), though BMI doesn't account for muscle, body fat percentage, or body composition, making it a general guideline for adults. To find your weight in kg, calculate your BMI: Weight (kg) / Height (m)², and use the ranges (Healthy: 18.5-24.9; Overweight: 25-29.9; Obese: 30+) to see where you stand.
You are in your healthy weight range.
A healthy BMI for an adult is between 20 and 25. For older Australians over the age of 74 years, your general health may be more important than being mildly overweight. Some researchers have suggested that a BMI range of 22-26 is acceptable for older Australians.
At the same time, scientists uncovered another fact: men are also attracted to women with curves. This means that women with a BMI of 22.8 to 24.8 are the most appealing to men. This corresponds to a height of 170 cm and a weight of 70 kg.
Sleep deprivation has long been linked to an increased risk of becoming overweight or obese. Researchers found that getting less than seven hours of sleep resulted in weight changes and may lead to weight gain, either by increasing food intake or decreasing energy burned.
70kg isn't inherently heavy for a woman; it depends heavily on height, body composition, and build, but it often falls into a healthy range for taller women, while for shorter women, it could lean towards overweight. For example, a 175cm (5'9") woman at 70kg has a healthy BMI, but a 163cm (5'4") woman at the same weight might be considered borderline overweight, according to this article from The Daily Telegraph.
There is evidence to support the claim that drinking water can aid weight loss. A study by the National Institute of Health on overweight women found that increasing water intake led to a reduction in body weight, body mass index (BMI) and body fat percentage.
The distribution of the current BMI ranged from 17 to 35 for women and from 19 to 35 for men. The changes in BMI units ranged from 0.5 to 2.5 between the ages of 70 and 90 years but were greater for women than for men.
In Australia, a size 12 is generally considered a "straight" or "missy" size, falling within average ranges, but due to vanity sizing and inconsistent measurements across brands, it can represent different body sizes; health-wise, a larger waist (over 88cm for women) is a risk factor, and the actual average Australian woman is now closer to a size 16-18, meaning a size 12 is smaller than average, though "fat" is a subjective term related to body image and health metrics like BMI, not just a single number.
Ozempic is typically recommended for individuals who have a BMI of 30 or higher, which falls into the obese category, or for those with a BMI of 27 or higher who have additional health concerns such as high blood pressure, type 2 diabetes, or high cholesterol.
A waist circumference of more than 35 inches for women or more than 40 inches for men increases your risk. To correctly measure your waist circumference, stand and place a tape measure around your middle, just above your hipbones. Measure your waist just after you breathe out.
Generally used to refer to males who could be overpowered and taken advantaged of by other males who are above 200 pounds. Could also be used as a general statement about a male weighing approximately 140-160 pounds or 60-70 kilograms.” - Urban Dictionary.
BMI Categories – What Your Results Mean
If you're 165 cm tall, a healthy weight is between 54 kg and 68 kg. If you weigh over 81 kg, your BMI is above 30, placing you in the obesity range.
Whether 80 kg is overweight for a woman depends entirely on her height, as weight is relative to body size; using Body Mass Index (BMI) or height charts shows that for shorter women (e.g., under 160cm/5'3"), 80kg is likely obese, while for taller women (e.g., over 175cm/5'9"), it might fall within the healthy to overweight range, but always use a calculator for accuracy as BMI doesn't account for muscle.

But BMI Isn't Everything
According to Dr. Cerna, for some people, BMI can be skewed. “If you have a lot of muscle mass, such as in athletes and bodybuilders, your BMI will be overestimated. In seniors and people with less muscle mass, BMI may be underestimated,” said Dr.
