For a 5'2" (157 cm) person, a healthy weight range is generally around 47-60 kg (104-132 lbs), but this varies by gender, body frame, and muscle mass, with some charts suggesting closer to 49-58 kg for women and 48-59 kg for men, emphasizing that formulas are estimates and consulting a doctor for personal advice is best.
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.
56kg is smack bang in the middle of the healthy BMI range, however it depends also on your frame (like are you big boned, wide-hipped/shouldered?) and musculature (if you are very muscular you may want a few extra kg to account for the extra muscle).
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.
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.
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.
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.
How to get your BMI down
Most people begin to notice a shift in the appearance of their face around their 40's and 50's, with some also noticing a change in their 30's. But with these physical changes brought on by aging also comes a change in the appearance of our face - Luckily, there is treatment available.
Boosts Your Metabolism
Drinking water helps the body burn fat. Studies show that drinking 17 ounces of water can increase the metabolic rate by 30% in both men and women. Even mild dehydration can slow down metabolic rate by 3%.
Do resistance training and high-intensity workouts – Lifting weights and doing exercises that use resistance weights or the weight of the body helps build muscle. Muscle mass has a higher metabolic rate than fat, which means that muscle mass requires more energy to preserve and may increase your metabolism.
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 size 8 is generally considered a Small (S) in US sizing but can sometimes be an Extra Small (XS) in Australian (AU) or UK sizing, though it often falls into a Small (8-10 AU/UK) for many brands, with some brands sizing it as XS (6-8 AU/UK) for tops/dresses, highlighting that sizing varies significantly by brand, so always check the specific size chart.
Under 18.5 - you are very underweight and possibly malnourished. 18.5 to 24.9 - you have a healthy weight range for young and middle-aged adults. 25.0 to 29.9 - you are overweight.
Body mass index (BMI) is a medical screening tool that measures the ratio of your height to your weight to estimate the amount of body fat you have. Healthcare providers calculate BMI by using weight in kilograms (kg) divided by the square of height in meters (m2).
BMI doesn't differentiate between fat, bone and muscle; therefore, it may be less accurate for older people, who tend to lose muscle mass and bone density as they age. (That's why people over 65 may benefit from a slightly higher BMI, between 25 and 27.)
