For a 160cm female, the ideal weight range is generally considered around 51 kg to 64 kg, corresponding to a healthy Body Mass Index (BMI) of 20-25, though factors like muscle mass, age, and body composition matter, with roughly 56kg being a common mid-point for a healthy BMI.
You can use this table to determine your acceptable weight range for your height (in cm), by finding the weight corresponding to a BMI level of 20 and 25. For example, if you are 160cm tall, your ideal weight range is between 51.2 and 64.0 kg, and you are obese if you are above 76.8 kg.
No, 56 kg (about 123 lbs) for someone 160 cm (about 5'3") tall is considered a healthy weight, not overweight, with a Body Mass Index (BMI) of approximately 22, falling within the normal range (18.5-24.9). While BMI is a good indicator, other factors like muscle mass, body composition, and where you carry fat can also affect health, so consulting a doctor is always best for personalized advice.
Your healthy weight range in Australia is generally a Body Mass Index (BMI) between 18.5 and 24.9, calculated from your height and weight, indicating a normal weight, but it's a guide, with ranges like 18.5-24.9 considered healthy, 25-29.9 overweight, and 30+ obese, with waist circumference also important for assessing risk, say NSW Health, Medibank, and Healthdirect, Australian Institute of Health and Welfare, Better Health Channel, and Cancer Australia.
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.
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.
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.
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.
You should step on the scale first thing in the morning. That's when you'll get your most accurate weight because your body has had the overnight hours to digest and process whatever you ate and drank the day before.
160 (presumably pounds, as kg is already the target unit) is approximately 72.57 kilograms (kg), calculated by multiplying 160 by the conversion factor 0.45359237, which is often rounded to about 72.6 kg or 73 kg for simplicity in daily use.
For example, if you weigh 56 kg and your height is 160 cm, your BMI is almost 22, which is within the normal range.
For adults ages 20 years and older, BMI incorporates weight and height, but it does not take age or sex into account. A woman tends to have more body fat than a man with the same BMI. Likewise, an older person tends to have more body fat than a younger person with an equal BMI.
How to get your BMI down
BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body composition, and racial and sex differences, say researchers from the Perelman School of Medicine, University of Pennsylvania.
New research from body-positive fashion app Mys Tyler shows that the average Australian woman wears size 16. The data was pooled from over 32,000 Mys Tyler users, which has been weighted to be representative of Australian women aged 18 to 75 as well as verified by global research firm Insights Exchange.
A 70kg woman usually falls into a Medium (M) to Large (L) dress size, depending heavily on height, body proportions (bust, waist, hips), and the specific brand's sizing, with some charts placing 70kg at the upper end of Medium and others at the lower end of Large. For example, some guides link 70kg with a Medium, while others connect it to a Large, so checking the brand's specific size chart with your measurements (bust, waist, hips) is crucial.
A women's Medium (M) can be either a size 12 or 14, or even both (12-14), depending on the brand, country (US, UK, Aus), and whether it's a top or bottom, but generally, size 12 often aligns with Medium, while size 14 can lean towards a Large (L), though some retailers use 12-14 as a unified Medium. Always check the specific brand's size chart, as sizing varies widely.
The answer is yes — but not as drastically as you may think. Metabolism drives the body's basic functions, including converting food into energy to be used immediately or stored for later use. Research shows that metabolism starts to slow down after age 60,2 which may lead to body composition changes or weight gain.
