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.
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].
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. If your BMI is 18.5-20, you're a bit underweight and can't afford to lose more.
Believe it or not, skinny people often do NOT possess the low body fat one might expect due to their low muscle mass in relationship to what body fat they do have. Lean people, on the other hand, possess a much higher amount of lean body mass (mostly muscle) coupled with a very low amount of body fat.

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.
You can check if you're underweight by using our BMI healthy weight calculator, which shows your body mass index (BMI). If your BMI is below 18.5, this suggests that your weight may be too low. If you're underweight, or you're concerned that someone you know is, tell a GP or practice nurse.
If you have a BMI of less 18.5, you're technically considered underweight. If your flexed biceps measure less than 13.3″ in circumference, that's a good sign that your muscles are smaller than average, and so you could be considered skinny.
The best measure of whether you are a healthy weight is the body mass index (BMI). This is calculated using your weight and your height. In adults, a healthy weight range is a BMI of 18.5 to 24.9. If your BMI is under 18.5 then you would be considered underweight.
Being small, or even underweight according to the numbers, doesn't mean you need to gain weight. A healthy weight isn't necessarily “seen” and not a sign that something is wrong or that a person has an eating disorder.
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.
Earlier research has found that the most desired BMIs are approximately 18-20, considerably below the average or typical values of young women in well-fed populations.
Common reasons for someone to have belly fat even when they're skinny is: Being too sedentary (inactive), which builds visceral fat around the organs and abdominal fat. Eating too many processed foods, which stores at the belly.
He explained that "muscle is more dense than fat, so an identical volume of it will weigh more than fat." Exercise physiologist Krissi Williford, MS, CPT, of Xcite Fitness, agreed and said even though your muscle mass weighs more than your fat, "it takes up less space, which is why you look leaner and more toned."
Maintaining a healthy body weight is important, but it should not be confused with being physically fit. Simply being thin does not protect you from health conditions related to a sedentary lifestyle.
Mostly, losing weight is an internal process. You will first lose hard fat that surrounds your organs like liver, kidneys and then you will start to lose soft fat like waistline and thigh fat. The fat loss from around the organs makes you leaner and stronger.

The phrase 'skinny fat' or metabolically obese normal weight (MONW) is used to describe someone who appears to be lean, but actually has a high body fat percentage. If they were to calculate their body mass index (BMI) or even weigh themselves, they may appear to be healthy, but this can be deceiving.
“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.”
All in all, it can take anywhere from one week to several months to see noticeable weight loss results. It all depends on your daily activity level, your exercises, and how much you eat each day.
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.
Thin means not having a lot of extra flesh on the body; this is the opposite of fat. Slim means being gracefully thin whereas skinny means being unattractively thin. This is the main difference between thin, slim and skinny.
Even thinner than 'skinny' is scrawny (also a slightly informal word). Someone who is scrawny is so thin that their bones stick out: He was a scrawny little kid. Gaunt, meanwhile, is used to describe a very thin face, sometimes a face that is thin because a person is ill: Her face was gaunt and grey.
