If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
Weight of a boy between 30-39 years should be up to 90.3 kg, while the weight of a girl should be up to 76.7 kg. Weight of a 40-49 years old boy should be 90.9 kg, while a girl should weigh 76.2 kg. The weight of a 50-60 year-old-boy should be up to 91.3 kg and the weight of the girl should be up to 77.0 kg.
Average adult human weight varies by continent, from about 60 kg (130 lb) in Asia and Africa to about 80 kg (180 lb) in North America, with men on average weighing more than women.
If your BMI is: 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.
Your body mass index, or BMI, is the relationship between your weight and your height. A BMI of 20-25 is ideal; 25-30 is overweight and over 30 is obese. If your BMI is under 18.5, you're considered underweight.
As you age, your muscle mass decreases and your fat mass increases. Fat is less metabolically active than muscle—you don't need as many calories to maintain fat as you do to maintain muscle. Hormonal changes can also lead to weight gain.
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.
Using a height of 1.73 m (5 ft 8 in) as a guide, as it squares to three and also lies conveniently between average adult male and female heights, overweight is defined as 75 kg and obese as 90 kg. The risk of the extra 15 kg, or 33 lb, is modest when compared with other risk factors.
under 18.5kg/m2 – you are considered underweight and possibly malnourished. 18.5 to 24.9kg/m2 – you are within a healthy weight range for young and middle-aged adults. 25.0 to 29.9kg/m2 – you are considered overweight. over 30kg/m2 – you are considered obese.
ICMR-National Institute of Nutrition (NIN) has redefined the ideal or reference Indian adult man and woman with regard to age to 19-39 years instead of 20-39 years. The body weight has been put at 65 kg for males and 55 kg for females while earlier, it was 60 kg and 50 kg respectively, which are a decade old.
BMI values of less than 18.5 kg/m2 are considered underweight. BMI values between 18.5 kg/m2 to 24.9 kg/m2 are healthy. BMI values between 25 kg/m2 to 30 kg/m2 are overweight. BMI values greater than 40 kg/m2 are considered obese.
Weight loss can be different for men and women. Men tend to gain weight until age 55, and then slowly start to lose it in the years that follow. This could be because men produce less testosterone after this age. Women, on the other hand, usually stop gaining weight once they hit age 65.
People who carry more weight tend to look a little younger. How much younger? Twin studies revealed that a person who has a BMI 4 points higher can look 2-4 years younger. The reason is that the face naturally loses fat as we get older.
Why does weight change as we age? As we age, metabolism — how the body gets energy from food — can change. This means that some older adults must become more active or eat fewer calories to maintain or achieve their ideal weight. Other older adults may lose weight unintentionally.
The finding of the study suggests that people in middle age certainly gain weight and it is harder for them to lose it, but slow metabolism is not the real reason behind it. It was revealed that from the 20s to the 50s the energy expenditure is the most stable.
Although the prevalence of obesity increases with age, weight gain is actually greatest across the younger years of adult life — late twenties and thirties — and diminishes gradually over time as adults get older, says Tucker.
Losing weight in your 30s may be more challenging than when you were younger, but it's not impossible. It's important to have patience and make mindful, nutritious choices. This includes eating a balanced diet, getting enough sleep, drinking plenty of water, and making sure to get your body moving.
A BMI calculation in the healthy weight range is between 18.5 to 24.9. For Black, Asian and some other minority ethnic groups, the healthy weight range is 18.5 to 23. For people of White heritage, a BMI: below 18.5 is underweight.
If you are losing weight rapidly or having trouble gaining weight, it may be time to contact your provider for help. A natural thin-build is OK, and if you maintain a healthy diet and exercise regularly – it's not a health concern.
The World Health Organisation (WHO) defines a healthy adult BMI as being between 18.5 and 25. A BMI less than 18.5 indicates underweight (possibly caused by disease, malnutrition or eating disorders such as anorexia nervosa) and a BMI over 25 as overweight (possibly caused by poor diet choices or lack of exercise).
