There's no single "ideal weight" for everyone; it depends on height, age, sex, and body composition, but the Body Mass Index (BMI) offers a general guide, with 18.5 to 24.9 typically considered a healthy range for adults, though it doesn't distinguish muscle from fat. Other methods use formulas based on height (like the Devine or Robinson formulas), while waist-to-height ratio and overall fitness also provide insights into a healthy weight.
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.
It is calculated according to BMI = weight/height² . The optimal, healthy range for BMI is between 18.5 and 24.9. Our ideal weight calculator converts this back into weight, presenting to you the range of appropriate weights for your height.
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.
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.
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.
A BMI of 29.1 for a 5'2" 160 lbs female indicates overweight status and an elevated risk for some health issues. However, the significance of BMI should be viewed within the context of overall health, body composition, lifestyle factors, and other individual circumstances.
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.
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.
Using figure rating scales, Aniulis et al. (27) found that the most frequently selected ideal body had a BMI of 19.79, closely followed by an underweight ideal of 18.26. Ahern et al. (28) found that a BMI of 20 was considered the most attractive, while Swami et al.
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.
However, BMI cannot differentiate between body fat and muscle mass. This means there are some exceptions to the BMI guidelines: Muscles – body builders and people who have a lot of muscle bulk will have a high BMI, but are not overweight.
Therefore, a BMI between 25 and 35 kg/m2 may be optimal for health in the older population. Data from this study suggest that the optimum BMI range is 31–32 kg/m2 for female and 27–28 kg/m2 for male.
Calorie Deficit
Decreasing the amount of calories consumed on a daily basis will inevitably aid weight loss and as a result, lower BMI. By creating a food diary and tracking the amount of calories consumed with each meal, will ensure that you are eating within your recommended allowance and taking accountability.
Ozempic is typically recommended for individuals who have a BMI of 30 or higher, which falls into the obese category, or for those with a BMI of 27 or higher who have additional health concerns such as high blood pressure, type 2 diabetes, or high cholesterol.
No, a BMI of 23 is considered within the healthy weight range (18.5–24.9) for most adults, not "fat," but it's important to remember BMI doesn't measure body fat directly; well-muscled individuals might have a higher BMI with low fat, while others with a low BMI could still have high body fat.

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.
