There's no single "correct" height and weight; it varies by age, sex, genetics, and body composition, with growth charts (like CDC/WHO charts) showing ranges, not absolutes, for children, while for adults, Body Mass Index (BMI) between 18.5-24.9 is generally considered healthy, but lifestyle factors like diet and exercise are crucial for overall health.
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.
For Infants < 12 months: Weight (kg) = (age in months + 9)/2 For Children aged 1-5 years: Weight (kg) = 2 x (age in years + 5) For Children aged 5-14 years: Weight (kg) = 4 x age in years.
Changes in total body weight vary for men and women. Men often gain weight until about age 55, and then begin to lose weight later in life. This may be related to a drop in the male sex hormone testosterone. Women usually gain weight until age 65, and then begin to lose weight.
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.
Your most consistent and "true" weight is generally in the morning, after using the bathroom and before eating or drinking anything. This provides the most accurate baseline because your body has processed the previous day's food and fluids overnight, resulting in less fluctuation from digestion, water intake, and daily activities. Weighing at the same time, in the same minimal clothing, and under consistent conditions (like in the morning) helps track trends better than weighing at night or randomly.
5 Pound Weights
The heaviest weight recommended for older adults is 5 pounds. These can be used for exercises such as deadlifts, bicep curls, and shoulder presses. It's important to remember that the weight selection will vary based on an individual's strength level and physical ability.
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.
But over the long term, a person's growth may be affected by not getting enough sleep. That's because growth hormone is normally released during sleep. If someone consistently gets too little sleep (known as "sleep deprivation"), growth hormone is suppressed. Lack of sleep also can affect other hormones.
Based on extensive research, different BMI categories were set for older adults, where healthy weight was defined as a BMI ranging from 23 to 29.9 kg/m². This stems from the fact that researchers noticed that a BMI below 23 and above 33 is associated with a significantly increased risk of mortality.
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.
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.
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.
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.
The Devine formula for calculating ideal body weight in adults is as follows:
In fact, we begin to lose muscle mass at about age 30, with more rapid loss at around age 60 and beyond. Muscle tissue burns calories faster than other tissues, which means as we lose muscle, our ability to lose weight also diminishes.
“Research tells us that the number one reason for increased belly fat is a decrease in physical activity, but for women in the menopause transition, there are almost always other factors at play, including hormonal changes, stress levels, dysfunctional sleep patterns and some medications.” Marino explains why abdominal ...
The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.
