It's not about being "skinny" or "big," but about being healthy, fit, and having good body composition, as research shows fitness and muscle mass are better predictors of longevity than weight or leanness alone; a "skinny" person with high body fat (skinny-fat) can be less healthy than an overweight, active person, while being fit with muscle offers more protection than being thin but unfit, regardless of size.
Many people assume that having a smaller body or lower body weight is a sign of good health. But this is a common misconception. A person's weight is just one of many factors that influences their health. And, what's more, a low body weight can come with real health risks.
Body Shapes with the Highest Risk of Health Problems
Apple and pear body shapes tend to have the highest risk. Apples tend to be at greater risk for heart disease, diabetes, and strokes because they hold a larger amount of tummy fat.
The measure of body fat distribution, the WHR, was found to be the critical variable associated with attractiveness. Normal weight female figures with low WHR were judged to be most attractive and were assigned many desirable qualities.
For years, excess weight has been viewed as one of the biggest threats to health. But new research suggests the opposite may be true: Those who are too thin — or even on the lower end of a "healthy" weight — may face greater health risks than people who are overweight.
Several studies also back these findings. One study conducted by Northwestern University's Body and Media Lab polled both men and women about what female body type men were most attracted to. Most women believed men preferred skinnier body types, but most men actually chose heavier or curvier body types.
Women who weighed less at age 20 and put on less weight as they aged were more likely to live longer than heavier women. Height played a major factor: the study found women who were taller than 5 feet 9 inches were 31% more likely to live into their 90s than women who were less than 5 feet 3 inches.
The study, published in the Lancet Diabetes and Endocrinology, showed that life expectancy for obese men and women was 4.2 and 3.5 years shorter respectively than people in the entire healthy BMI weight range. The difference for underweight men and women was 4.3 (men) and 4.5 (women) years.
Yes, the idea that people see you as significantly more attractive (often cited as around 20% more) than you see yourself is a common concept in psychology, stemming from research suggesting we are overly critical of our own appearance due to familiarity and focusing on flaws, while others see a more complete picture including personality, kindness, and humor. This difference happens because you see yourself in mirrors (reversed) and photos (often unflattering angles/lighting) while others see you as you are, in real-time, noticing your overall vibe, confidence, and smile more than minor imperfections.
Again, women consistently chose the bodies of the guys who looked strong, lean, and athletic in a natural and healthy way. Being on the thinner side was perfectly fine, but being skinny wasn't. This time, though, more women preferred the most muscular guy over the skinny guy.
Nevertheless, the least attractive (cluster 1—thin torso and thin legs; or cluster 2—large torso and large legs) and the most attractive images (thin torso and medium legs) can be established.
That's largely due to hormones. Estrogen encourages fat to settle in the hips and thighs as a way of preparing the body for pregnancy. Genetics also play a big role in where your body prefers to store fat, and for some people, that means the lower body holds onto it longer than other areas.
ECTOMORPH. The extreme ectomorph physique is a fragile and delicate one. The bones are light, joints are small and muscles are slight. The limbs are relatively long in proportion and the shoulders droop.
Sometimes, being underweight can have more immediate adverse health effects than being overweight. Often, fatness is linked to high blood pressure and cardiac issues. But, being too thin takes a more immediate toll on your heart.
The physique of a slim waist, broad shoulders and muscular chest are often found to be attractive to both females and males.
West Virginia topped WalletHub's 2025 ranking of the most overweight and obese states in the U.S., published Nov. 4, while Colorado is the healthiest-weight state.
According to psychology, when we see ourselves in the mirror, we tend to think of ourselves as prettier, than how we actually look to others, in real life. That's the perception of the mirror, vs what you look like to others in real life.
Some people hit peak attractiveness in their twenties. Some people don't really hit their peak until they come into the maturity and elegance of their thirties or even forties. And some people age into silver foxes in their fifties. It really depends on the person.
Top 6 Signs You're Attractive
Being Over or Underweight. Everyone seems to understand that being overweight or obese can add stress to the body that accelerates the aging process, but so does being underweight. Not only this, but underweight people lack the pads of fat beneath the skin that plump out wrinkles.
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].
Other studies show that the lowest mortality in the entire range of BMI is obtained in the overweight range (25–29.9).
Hourglass is the rarest body type, with only estimated 8% of women having this figure. Here's the thing: hourglass bodies are versatile. The stereotypical hourglass is too narrow of a depiction that often fails to capture the true beauty and diversity of this shape.
Further lifestyle risk factors that significantly reduce a person's life expectancy include: obesity* (3.1/3.2 years), excessive alcohol consumption** (3.1 years, men only), and a high intake of red meat (2.4 years in women; 1.4 years in men).
While Shimizu and Colleagues10 found that blood type B was associated with longevity, Mengoli and Colleagues6 and Brecher and Hay12 concluded that group B was inversely correlated with age. In addition, there are isolated reports of group A7 and group O9 being associated with longevity.
