For a female who is 4'11" (150 cm) tall, an ideal weight range is generally considered to be around 39 to 48 kg (86 to 105 lbs), though this can vary based on muscle mass, body frame, and age, with some charts suggesting a slightly higher end. A healthy Body Mass Index (BMI) range (18.5-24.9) for this height often falls within the mid-to-upper part of this scale, around 48-54 kg.
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.
Short answer: generally underweight. At 160 cm and 45 kg the body mass index (BMI) is 17.6 kg/m2, below the World Health Organization's underweight threshold (BMI < 18.5). That number alone doesn't prove illness, but it does indicate increased risk for health problems and suggests at least an evaluation is warranted.
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 restroom and before eating or drinking anything, because your body has had time to digest overnight, leading to less fluctuation from food, liquids, and daily activities. Weighing at the same time, with minimal clothing, and under consistent conditions helps track trends more accurately than weighing at night when weight is higher due to meals and hydration.
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.
How to get your BMI down
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.
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.
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.
Ozempic is only licensed as a type 2 diabetes treatment in the UK. Another semaglutide-containing injection called Wegovy is licensed for weight loss. NHS doctors can't prescribe Ozempic for weight loss, but a private doctor may be willing to prescribe Ozempic off-label.
It is not known if Ozempic® will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people. Do not use Ozempic® if you or any of your family have ever had MTC, or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
Women with a waist size greater than 35 inches and men with a waist larger than 40 inches are at higher risk for heart disease and Type 2 diabetes, according to the National Heart, Lung, and Blood Institute.
BMI Categories – What Your Results Mean
If you're 165 cm tall, a healthy weight is between 54 kg and 68 kg. If you weigh over 81 kg, your BMI is above 30, placing you in the obesity range.
Does Drinking Water Aid Weight Loss? There is evidence to support the claim that drinking water can aid weight loss. A study by the National Institute of Health on overweight women found that increasing water intake led to a reduction in body weight, body mass index (BMI) and body fat percentage.
Remember meals, drinks and daily changes in schedule can affect weight readings. A couple of pounds here or there are not signs your body is changing. This is why weighing yourself after a bowel movement but before a meal helps maintain accuracy.
