Obesity is a medical condition, sometimes considered a disease, [8] [9] [10] in which excess body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over 30 kg / m 2 ...
In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. [2]
According to the Obesity Action Coalition, medications that may cause weight gain include: Anti-depressants: SSRIs such as Paxil, Zoloft, Celexa, and Prozac, and tricyclic antidepressants
The body volume index (BVI) was devised in 2000 as a computer, rather than manual, measurement of the human body for obesity and an alternative to the BMI BVI uses 3D software to create an accurate image of a person so BVI can differentiate between people with the same BMI rating, but who have a different shape and different weight distribution.
The study included 42 men and 63 women who, based on their body mass indexes, were not overweight or obese. They compared them to 23 men and 55 women who either were overweight or had obesity.
The study followed nearly 17 million people, the majority of whom were in the 26-75 age range, and found that after climbing steadily since 2013, rates of obesity in the U.S. fell 0.15% in 2023 ...
Obesity can have particularly damaging effects in young women as they begin menstruating earlier than non-obese girls, essentially enhancing the defects associated with obesity and fertility. [4] Obesity also affects fertility in men.
The reasons are biological and irreversible. As early as 1969, research showed that losing just 3 percent of your body weight resulted in a 17 percent slowdown in your metabolism—a body-wide starvation response that blasts you with hunger hormones and drops your internal temperature until you rise back to your highest weight.
