"Chubby" isn't a clinical term, but generally refers to having a higher body fat percentage, often falling into the overweight category (Body Mass Index (BMI) 25.0–29.9) or the lower end of obesity (BMI 30+), indicating excess fat distributed across the body without severe health risks yet, unlike "fat" which implies more significant accumulation and greater health risks. It's a softer term than "fat," suggesting more evenly distributed, less extreme body fat, but still above a "normal" weight.
Body mass index (BMI)
below 18.5 – you're in the underweight range. 18.5 to 24.9 – you're in the healthy weight range. 25 to 29.9 – you're in the overweight range. 30 to 39.9 – you're in the obese range.
For men, 20% body fat is generally considered in the "acceptable" or "average" range, bordering on "fitness" or slightly overweight, with some extra fat but no clear muscle definition, while for women, 20% is in the "fitness" or "good" category, showing some definition but not overly lean. The term "chubby" is subjective, but at 20% body fat, most people won't look extremely lean, though it's healthy for men and good for women, falling within typical ranges before obesity becomes a concern, say 8fit and InBody USA.
BMI between 18.5 and 24.9: you are in a healthy weight range. BMI between 25.0 and 29.9: you are considered to be overweight. BMI equal to 30.0 or above: you are considered to be obese.
Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. A body mass index (BMI) over 25 is considered overweight, and over 30 is obese.
The traditional diet in Japan is built around a base of rice and other grains, with plentiful consumption of vegetables and fruits, and also fish, but relatively little animal fat, meat and sweets. In Japan, the presentation of the food is very important, and particular attention is given to the colors and textures.
A weight of 70kg can fall within the healthy weight range for various individuals. Height plays a significant role. A shorter individual might find a BMI of 70kg within a healthy range, whereas a taller person could potentially fall into the overweight or even the obesity category using the same metric.
There is no single medical definition of "chubby," but generally speaking, a chubby body type is defined by a round, plump physique, a round face, and fuller midsection and arms.
You can be lean but still have hidden visceral fat which wraps around the organs in your abdominal cavity and is more dangerous than subcutaneous fat (the fat just beneath the skin that most of us think of as fat). This is what we call “skinny fat” or TOFI (Thin on the Outside, Fat on the Inside).
Sleep deprivation has long been linked to an increased risk of becoming overweight or obese. Researchers found that getting less than seven hours of sleep resulted in weight changes and may lead to weight gain, either by increasing food intake or decreasing energy burned.
Unhealthy body fat distribution
You may have a normal BMI but if you have a large waist circumference, you may have more fat in your abdomen than elsewhere. For men, an unhealthy waist circumference is greater than 40 inches. For women, an unhealthy waist circumference is greater than 35 inches.
The term skinny fat or normal weight obesity (NWO) refers to a person who is normal or below normal weight but has a higher than optimal body fat percentage and often lower than optimal lean body mass. A person with a skinny fat body type can have very high amounts of body fat as compared to a lean body mass.
Some health organizations define a healthy waist size very generally as 35 inches or less for women or 40 inches or less for men. Other experts also take height or hip measurements into consideration. Does waist size determine body fat? It's possible to have a large waist without being overweight.
14 is probably in the overweight category (depending on height obviously) and is not slim.
According to the CDC, people with a BMI of 18.5 or less are underweight. Those who fall between 18.5 to 24.9 are normal weight. Those between 25 and 29.9 fall within the overweight range. Health professionals characterize individuals as obese if they have a BMI greater than 30.
More importantly, men prefer girls with curves, as they feel more comfortable and secure when hugging or holding hands. And compared to skinny girls, chubby girls are more likely to be seen as sexy and feminine. Many men actually prefer girls with curves, as they think such girls are more lovable and charming.
Chubby = a bit plump, still within a range that can look healthy/cute. Fat = excess body fat, usually linked to being overweight or obese. "CHUBBY" AND "FAT" are often used interchangeably, but they can have different connotations.
Whether 80kg (176 lbs) is "heavy" for a woman depends on her height, body composition (muscle vs. fat), and frame, as Body Mass Index (BMI) can categorize it as overweight or obese for shorter women but might be healthy for taller individuals with significant muscle mass, though a BMI over 30 (obesity) is generally considered unhealthy for most. A single number doesn't define health; factors like fitness level, strength, and body shape matter more than just weight.
BMI Categories – What Your Results Mean
If you're 165 cm tall, a healthy weight is between 54 kg and 68 kg. If you weigh over 81 kg, your BMI is above 30, placing you in the obesity range.

The Japanese 80% rule, known as "Hara Hachi Bu", is a Confucian principle advising people to stop eating when they feel about 80% full, not completely stuffed, to support health and longevity. This practice encourages mindful eating, helps prevent overeating, and is linked to lower rates of illness and longer lifespans, particularly observed in Okinawan centenarians. It involves slowing down during meals, listening to your body's fullness cues, and appreciating food as fuel rather than indulging to the point of discomfort.
The hope is that the campaign will encourage healthy lifestyles and keep diabetes, heart disease and strokes in check. Still, it is not a crime to be fat in Japan, as most of these viral posts state. Japanese citizens can't be fined or imprisoned for being overweight.
