There's no single "ideal weight" for a girl, as it varies greatly by height, body composition (muscle/fat), and individual build, but health guidelines often focus on a healthy Body Mass Index (BMI) range (18.5–24.9) or use formulas like Hamwi, suggesting a healthy weight is relative to height, not just a number. What men find attractive varies, but health and confidence are universally appealing, so focusing on being healthy and comfortable in your own skin is key.
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.
50 kg (about 110 lbs) isn't a "perfect" weight for everyone; it depends heavily on your height, body composition (muscle vs. fat), age, sex, and frame size, with it potentially being healthy for shorter individuals but underweight for taller people, so using a BMI calculator and consulting a doctor is best for a personalized assessment.
A BMI of less than 18.5 kg/m² is considered underweight. A BMI between 25 kg/m² and 29.9 kg/m² is considered overweight. A BMI of 30 kg/m² or higher is considered obese. To check your BMI, type your height and weight into the BMI calculator for adults from the National Institute of Health.
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.
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.
Whether 80kg (176 lbs) is "heavy" for a woman depends on her height, body composition (muscle vs. fat), and frame, as Body Mass Index (BMI) can categorize it as overweight or obese for shorter women but might be healthy for taller individuals with significant muscle mass, though a BMI over 30 (obesity) is generally considered unhealthy for most. A single number doesn't define health; factors like fitness level, strength, and body shape matter more than just weight.
Adult BMI example
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.
A 45 kg woman may fall within the underweight category based on a BMI calculator, yet her overall health could be jeopardized by this condition. Extreme leanness, like any other deviation from a healthy weight range, is linked to potential health complications.
In adults, overweight, or pre-obesity, is defined as a BMI of 25-29.9 kg/m², while a BMI ≥ 30 kg/m² defines obesity.
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.
Female ideal body weight = 45.4 kilograms (100 lb) + 0.9 kilograms (2.0 lb) × (height (cm) − 152)
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.
“After a swim or a shower, your body can absorb 1 to 3 cups of water, increasing your true weight by a few pounds.”
If you're weighing yourself weekly, research shows that we're generally at our heaviest on a Sunday night and at our lightest on a Friday morning, so weighing in before breakfast on a Wednesday can give us the most accurate reading of our current weight [6].
Starting between ages 30 and 40, you may find losing weight and exercising more challenging. The exercise you do may not have the same effect as before. It's not necessarily a sign that something is wrong. This weight gain in middle age—known as “middle-age spread”—is a natural consequence of aging.
According to the Centers for Disease Control and Prevention (CDC), most 13-year-old females weigh around 76 to 158 pounds (lb), and most 13-year-old males weigh between 75 and 158 lb , but this can vary widely. The CDC has set guidelines for healthy weight and body mass index (BMI) in children.
