A healthy weight in kilograms (kg) varies by height, but generally falls into a Body Mass Index (BMI) range of 18.5 to 24.9, indicating a low risk for health issues, though factors like age, sex, and body composition matter. For example, a person 178 cm tall might have a healthy weight between approximately 58 and 74 kg, while someone 165 cm tall would aim for 50-65 kg, highlighting the need to use your specific height.
70kg (about 154 lbs) can be a healthy weight, but it depends heavily on your height, body composition, and overall health, as it falls within the normal Body Mass Index (BMI) range for many people but could be overweight for shorter individuals or underweight for very tall ones. For instance, a person 1.75m (5'9") tall with 70kg has a normal BMI, but height is key, so consulting BMI charts or a doctor is best for a personalized assessment.
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.
Body mass index (BMI)
A BMI calculation provides a single number, which the Centers for Disease Control and Prevention (CDC) categorizes as follows: A BMI of less than 18.5 suggests underweight. A BMI of between 18.5 and 24.9 suggests a healthy weight range. A BMI of between 25 and 29.9 may indicate overweight.
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.
A healthy weight for your height depends on factors like sex, body composition, and age, but generally, a Body Mass Index (BMI) between 18.5-24.9 is considered normal, which translates to weight ranges like 100-127 lbs for 5'1" or 110-140 lbs for 5'4" (for a BMI of 19-24), with broader ranges for "ideal" or moderate health. Use online calculators or charts based on your height, and remember these are guides; consult a doctor for personalized advice as BMI doesn't account for muscle mass.
A male who is under 200 pounds or 90 kilograms. 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.”
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.
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.
Why does weight gain happen faster with age? Dr. Mansuri: The metabolism naturally slows down with age, meaning the body burns fewer calories at rest and during physical activity. There is also a gradual loss of muscle mass, known as sarcopenia, which further reduces metabolic rate.
A weight of 70kg can fall within the healthy weight range for various individuals. Height plays a significant role. A shorter individual might find a BMI of 70kg within a healthy range, whereas a taller person could potentially fall into the overweight or even the obesity category using the same metric.
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.
Infants 0-12 months: weight (kg) = (0.5 × age in months) + 4. Children 1-5 years: weight (kg) = (2 × age in years) + 8. Children 6-12 years: weight (kg) = (3 × age in years) + 7.
14 is probably in the overweight category (depending on height obviously) and is not slim.
The country with the highest adult obesity rate is typically one of the Pacific Island nations, with Nauru often cited as number one, followed closely by American Samoa, Tokelau, and the Cook Islands, with rates exceeding 69% of the adult population. These island nations in Oceania consistently rank highest due to complex factors like diet changes and genetic predispositions.
Whether 56 kg (about 123 lbs) is "heavy" for a girl depends entirely on her height, body composition (muscle vs. fat), frame size, and age, as this weight can fall into a healthy range for taller individuals but might be considered heavier for shorter individuals. For example, a 160 cm (5'2") person with a BMI around 22 (normal range) could weigh 56 kg, while a shorter person might be in the overweight category, emphasizing that BMI is just a guide, and factors like muscle mass and how you feel are important too.
It is considered underweight, but not terribly underweight. The BMI for this height and weight is 18.3 and anything under 18.5 is underweight and might threaten health. A normal, healthy weight for your height would be between 111 and 150 pounds … so I would not be too worried about your current weight.
Ideal body weight (men) = 50 kg + 1.9 kg for every inch above 5 feet. Ideal body weight (women) = 49 kg + 1.7 kg for every inch above 5 feet.
