Excess weight or obesity boosts risk of death by anywhere from 22% to 91%—significantly more than previously believed—while the mortality risk of being slightly underweight has likely been overestimated, according to new CU Boulder research. The findings, published Feb.
If you are underweight, you may be at greater risk of certain health conditions, including malnutrition, osteoporosis, decreased muscle strength, hypothermia and lowered immunity. You are more likely to die at a younger age. Underweight women have less chance of becoming pregnant than women who are a healthy weight.
People who start adulthood with a body mass index (BMI) in the normal range and move later in life to being overweight -- but never obese -- tend to live the longest, a new study suggests.
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range.
Too Skinny: What BMI is Considered Underweight? From a clinical perspective, an individual is considered “too skinny” if they are deemed underweight. According to the Centers for Disease Control, an individual is underweight if their Body Mass Index (BMI) is below 18.5 [1].
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.
The medical term for 'skinny fat' is technically MONW or “metabolically obese, normal weight” and “Sarcopenic obesity”. Skinny fat people are often a normal weight (or underweight!) but because of their sedentariness, lack of muscle, or poor diet, they have a high percentage of body fat.
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.
Women with a BMI of less than 18.5 are considered underweight. The average woman's height is 5 feet, 4 inches. If you weigh 107 pounds or less at this height, you are considered underweight with a BMI of 18.4. A healthy weight range for that woman would be 108 to 145 pounds.
Compared to normal weight, underweight was associated with increased all-cause mortality (HR: 1.37; 95% CI: 1.14-1.65).
Here's what your number means: Less than 18.5 = underweight. 18.5 to 24.9 = normal weight. 25 to 29.9 = overweight.
When it comes to body shape and longevity, it's more helpful to compare apples and pears. That's the message of a study published in the journal PLOS ONE that found that pear-shaped people, who have comparatively thinner waists than people shaped like apples, tend to live longer.
Some underweight people are physically healthy. Low body weight can be due to a variety of health conditions, including: Genetics. If you've been thin since high school and it runs in your family, it's likely that you were born with a higher-than-usual metabolism.
There are also different tiers of anorexia based on BMI ranging from mild (<17.5), moderate (16-16.99), and severe (15-15.99), to extreme (<15). A BMI below 13.5 can lead to organ failure, while a BMI below 12 can be life-threatening.
A high metabolism.
If a person has a high metabolism, they may not gain much weight even when eating high-energy foods.

“Thinness is a heritable trait”
So thin people not only stay slim “by not having the obesity genes, but they also have different genes that protect them” from gaining weight, she said. The research concludes that “thinness, like obesity, is a heritable trait.”
No, you are fine as weight is irrelevant at such an age unless you are 80+ kgs, but even then as long as your diet and lifestyle is healthy, you are healthy. With this, most kids do overcome fat and turn out to be healthy young adults in their post teen years.
The approximate height where 45 kg is slightly underweight and 60 kg is slightly overweight is 5′5″ (165 cm). At 5′7″, 45 kg is considered very underweight but 60 kg is normal. At 6′ (183 cm), both are considered underweight.
By weighing 50 kgs you would not fall under the underweight category but a healthy BMI range of (18.9).
If your BMI is 25.0 to <30, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obesity range.
“As a person's weight increases above the average, so too does the likelihood that their prior experience involves smaller bodies. Because the brain combines our past and present experiences, it creates an illusion whereby we appear thinner than we actually are.”
This phenomenon is sometimes called “phantom fat” or “phantom fat syndrome.” The medical term is body dysmorphic disorder, said Giovanni M. Billings, Psy. D., a psychologist who works with surgical weight loss patients. The disorder can involve other aspects of a person's self image, not just weight.
