Death rate from obesity, 2019. Obesity is a risk factor for many chronic physical and mental illnesses.. The health effects of being overweight but not obese are controversial, with some studies showing that the mortality rate for individuals who are classified as overweight (BMI 25.0 to 29.9) may actually be lower than for those with an ideal weight (BMI 18.5 to 24.9).

Share of adults that are obese, 1975 to 2016. Obesity is common in the United States and is a major health issue associated with numerous diseases, specifically an increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, and cardiovascular disease, as well as significant increases in early mortality and economic costs.

Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
Obesity has been observed throughout human history. Many early depictions of the human form in art and sculpture appear obese. [2] However, it was not until the 20th century that obesity became common — so much so that, in 1997, the World Health Organization (WHO) formally recognized obesity as a global epidemic [3] and estimated that the worldwide prevalence of obesity has nearly tripled ...
These diseases include coronary heart disease, stroke, cardiomyopathy, arrhythmia, and heart valve or heart chamber problems. Cardiovascular disease is the leading cause of death in the United States and worldwide. [3] [4] In the United States, cardiovascular diseases account for one out of four deaths. [5]
Diets, not just in terms of obesity but also of food composition, can have a major impact on underlying factors (see also #Aging below), with reviews suggesting i.a. that a 20-years old male in Europe who switches to the "optimal diet" could gain a mean of ~13.7 years of life and a 60-years old female in the U.S. switching to the "optimal diet ...
Life expectancy may be confused with the average age an adult could expect to live, creating the misunderstanding that an adult's lifespan would be unlikely to exceed their life expectancy at birth. This is not the case, as life expectancy is an average of the lifespans of all individuals, including those who die before adulthood.
In the example of the obesity-cardiovascular disease relationship, the obesity is the collider, the outcome is cardiovascular disease, and the unmeasured variables are environmental and genetic factors – given that obesity and cardiovascular disorders are often associated with each other, medical professionals may be reluctant to consider ...
