What exactly counts as being "skinny?" Some healthcare experts believe a BMI in the 15-18 range to be clinically underweight. This seems to fall pretty close to what many everyday people consider to be "skinny" with a BMI of 18 or lower frequently listed as the indicator of someone considered to be slim.
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. 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.
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.
Body Mass Index (BMI)
BMI scores of 20 to 24.9 are considered normal, scores of 25 to 29.9 are overweight, scores of 30 to 34.9 are obese, and scores above 35 are extremely obese. Scores under 20 are considered underweight. You can easily calculate your score using a calculator.
Underweight: Less than 19.1 for women, Less than 20.7 for men. Ideal weight: 19.1 to 25.8 for women, 20.7 to 26.4 for men. Marginally overweight: 25.8 to 27.3 for women, 26.4 to 27.8 for men. Overweight: 27.3 to 32.2 for women, 27.8 to 31.1 for men.
The Skinny on Underweight
The American Dietetic Association (ADA) defines the ideal body mass index (BMI) as between 20 and 25. Thus, anyone below that range would be considered underweight and those with a BMI from 18.5 to 17.5 extremely underweight.
Normal: BMI of 18.5 to 24.9. Overweight: BMI of 25 to 29.9. Obese: BMI of 30 or higher.
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to <25, it falls within the healthy weight range. 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.
According to the DSM-5, a diagnosis of anorexia nervosa (AN) or “anorexia BMI” requires that someone have a BMI of less than 18.5.
Weighing too little can contribute to a weakened immune system, fragile bones and feeling tired. 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.
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.
A BMI of 19 is considered a healthy weight. With a BMI of 19, no weight loss procedure is necessary or recommended.
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.
A BMI of 23 is considered normal.
A BMI of 22 is considered normal. With a BMI of 22, no weight loss procedure is necessary or recommended. Useful information: If you have a BMI of 29 or greater than 29 a bariatric surgery procedure will be needed.
Muscles are denser and heavier than body fat, so if you have high muscle mass, your BMI might indicate that you're overweight or obese. BMI treats a person's weight as one entity, instead of accounting for muscles, bone density and fat, which all make up a person's weight.
A BMI of 19 or 20. A weight of 110–120 pounds (50kg–54.5kg)
Ideally, your BMI should be between 18.5 and 24.9. A BMI of 25 or over indicates that the person concerned is overweight, while obesity is defined as a BMI of over 30. Someone with a BMI of 20.5 is therefore within the normal weight range (see table).
First, what is skinny fat? “Skinny fat” simply describes a state in which someone has too little muscle mass and too much body fat. People who are skinny fat often look normal or even skinny when wearing clothes, but look soft, weak, and flabby underneath. Hence the name, “skinny fat.”
BMI ranges
below 18.5 – you're in the underweight range. between 18.5 and 24.9 – you're in the healthy weight range. between 25 and 29.9 – you're in the overweight range. 30 or over – you're in the obese range.
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.
What's a normal BMI? A normal BMI is between18. 5 and 25; a person with a BMI between 25 and 30 is considered overweight; and a person with a BMI over 30 is considered obese.
