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, on the other hand, is a chronic disease and a risk factor for a range of health conditions. Directly or indirectly, it might require management and attention over the course of a person ...
The researchers cautioned that considering obesity solely as a risk factor, rather than a disease, may prevent individuals who are unwell due to obesity from accessing timely care.
At least 300,000 premature deaths, and $90 billion in direct healthcare costs are caused by obesity and sedentary lifestyle per year in the US alone. [23] The risk is higher among those that sit still more than five hours per day. It is shown to be a risk factor on its own independent of hard exercise and BMI.
Tailored activity to one's fitness level also encourages the body to heal properly and prevent any injuries as a result of exercise. [16] Physical inactivity leads to less energy expenditure and is a factor that impacts obesity rates in both children and adults. [17]
The CDC has found that obesity is the single strongest risk factor for severe COVID-19 illness. [51] Complications are either directly caused by obesity or indirectly related through mechanisms sharing a common cause such as a poor diet or a sedentary lifestyle. The strength of the link between obesity and specific conditions varies.
Numerous large studies have demonstrated that eating ultraprocessed food has a positive dose-dependent relationship with both abdominal obesity and general obesity in both men and women. [27] Consuming a diet rich in unprocessed and minimally processed foods is linked with lower obesity risk and less chronic disease.
Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity.As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients (low-fat, low-carbohydrate, etc.), have been shown to be no more effective than one another.
