Often, fatness is linked to high blood pressure and cardiac issues. But, being too thin takes a more immediate toll on your heart. Being underweight can lead to fatigue, dizziness, brain fog, fertility problems, and a weakened immune system.
If you are underweight, you may be at greater risk of certain health conditions, including malnutrition, osteoporosis, decreased muscle strength, hypothermia and lowered immunity. You are more likely to die at a younger age.
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.
The Bottom Line
Both obesity and being out of shape increases your chances for a number of diseases and early death. However, the person who is lean but doesn't exercise regularly may not be in such good health after all. Being active and fit is good for you regardless of your body size.
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.
Clinically underweight or dangerously skinny for a man would be: A BMI of 15, 16, 17, or 18. A weight of 100–120 pounds (46–55kg)
Many people use low body weight to excuse unhealthy eating and physical inactivity. But body weight is not the best indicator of internal well-being. A much better indicator is your diet. When it comes to your health, it's what's on the inside that counts and you really are what you eat.
So yes, you can be overweight or obese and 1) be fit and 2) be healthier as a result of being fit. The other side of the coin, and another important take home message, is that you can be normal weight, unfit, and be at a greater risk of dying from a heart attack than your obese, but fit, counterpart.
Originally Answered: Did being thin make you happier ? No - but there is a link. If you are overweight and DO mind it, being thin might help you to be happy - but many people find that was not the root cause, as they were more unhappy with themselves, not their body shape.
