Some people have a naturally low BMI due to physical characteristics that run in their family. A high metabolism. If a person has a high metabolism, they may not gain much weight even when eating high-energy foods. Frequent physical activity.
Unfortunately, less than one in 50 people fall into the naturally slim category. Professor John Speak-man, who led the study from the University of Aberdeen, said: “Often when people talk to super-lean individuals, they say that they can eat whatever they want.

Body size is not as much of an indicator of health as you might think. Weight and health are not correlated. Your health depends more on what you eat and how well you manage stress than the number you see on the scale. Health can exist in every size.
After the yearlong study, findings showed that heavier men with obvious bellies were able to last for an average of 7.3 minutes in bed, while thinner men barely lasted for two minutes, being more likely to suffer from premature ejaculation.
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. You also may have a naturally small appetite.

Anorexia nervosa is a clinical diagnosis, like most mental health disorders, meaning that there is no specific laboratory test or imaging study that can confirm the diagnosis. Constitutional thinness is an underweight state with no changes in eating behaviors.
The secret to staying skinny is eating less... not exercising more, study finds. Skinny people don't exercise more than the rest of us — they just eat less, a study suggests. It has long been thought that naturally slim people move more so are able to eat whatever they like.
What exactly counts as being "skinny?" Some healthcare experts believe a BMI in the 15-18 range to be clinically underweight.

From the two illustrations, lean muscle is the healthier option in the long run because it is easier to stick to a routine that offers flexibility and is also a much more natural way to stay fit and workout.
The scientists found that thin people have a variant of what's known as the ALK gene. It's this variant of the gene that facilitates a resistance to weight gain, no matter what diet you're on, a finding suggested by follow-up experiments with mice and flies.

We might think of weight-related genes as having a 'skinny' and 'curvy' allele. Thinner parents are likely to have more of the skinny alleles,increasing the chance of passing them on to their children. A child who inherits more of the skinny alleles from their parents will be naturally thinner,” she added.
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.
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.
