If enough weight is gained due to increased body fat deposits, one may become overweight or obese, generally defined as having more body fat (adipose tissue) than is considered good for health. [1] The Body Mass Index (BMI) measures body weight in proportion to height and defines optimal, insufficient, and excessive weight based on the ratio. [2]
On average obese people have a greater energy expenditure than normal weight or thin people and actually have higher basal metabolic rates. [45] [46] This is because it takes more energy to maintain an increased body mass. [47] Obese people also underreport how much food they consume compared to those of normal weight. [48]
Body composition in general is hypothesized to help explain the existence of metabolically healthy obesity—the metabolically healthy obese are often found to have low amounts of ectopic fat (fat stored in tissues other than adipose tissue) despite having overall fat mass equivalent in weight to obese people with metabolic syndrome.
That means muscular people, including athletes, can have high BMI and could be considered on paper to have obesity when in reality they do not have too much body fat, also known as adiposity.
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 ...
More than 40 percent of Americans classified as obese now say they experience stigma on a daily basis, a rate far higher than any other minority group. And this does terrible things to their bodies. According to a 2015 study, fat people who feel discriminated against have shorter life expectancies than fat people who don't. “These findings ...
The thrifty genotype hypothesis has been used to explain high, and rapidly escalating, levels of obesity and diabetes among groups newly introduced to western diets and environments, from South Pacific Islanders, [9] to Sub Saharan Africans, [10] to Native Americans in the Southwestern United States, [11] to Inuit.
Prevalence estimates of MHO have varied from 6 to 75 percent, [7] and it has been argued that between 10 and 25 percent of obese individuals are metabolically healthy. [8] One study found that 47.9% of obese people had MHO, while another found that 11% did. [3] It seems to be more prevalent in women than men, and its prevalence decreases with ...
