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).

Obesity is a disease characterized by having excessive body fat, increasing a person’s risk for many serious health problems, such as heart disease, diabetes, and even some cancers
Obesity is the source of about 15% of all preventable cancers. [5] [6] [7] In 2018, Chinese researchers performed a systematic review and comprehensive quantitative meta‐analysis of cohort studies reporting body mass index (BMI) and the risk of 23 cancer types, providing epidemiological evidence supporting the association between BMI and ...
A BMI of ≥ 35 kg/m 2 and experiencing obesity-related health conditions or ≥ 40 or 45 kg/m 2 is morbid obesity. A BMI of ≥ 45 or 50 kg/m 2 is super obesity . As Asian populations develop negative health consequences at a lower BMI than Caucasians , some nations have redefined obesity; Japan has defined obesity as any BMI greater than 25 ...
The study confirms that both obesity and metabolic syndrome increase our “breast cancer health burden” but supports, at least in part, differential associations for each risk factor with ...
About 40% of American adults are living with obesity — and for many, it can feel a bit like a roller-coaster as their weight fluctuates. Experts explain the science behind "yo-yo dieting."
While some negative health outcomes associated with obesity are accepted within the medical community, the health implications of the overweight category are more controversial. A 2016 review estimated that the risk of death increases by seven percent among overweight people with a BMI of 25 to 27.5 and 20 percent among overweight people with a ...
The obesity paradox is also relevant in discussion of weight loss as a preventative health measure – weight-cycling (a repeated pattern of losing and then regaining weight) is more common in obese people, and has health effects commonly assumed to be caused by obesity, such as hypertension, insulin resistance, and cardiovascular diseases.
