This is the highest level of sustained daily nutrient consumption that is considered to be safe for, and cause no side effects in, 97.5% of healthy individuals in each life stage and sex group. The definition implies that the intake level would cause a harmful nutrient excess in just 2.5%.
In 2022, over 1 billion people lived with obesity worldwide (879 million adults and 159 million children), representing more than a double of adult cases (and four times higher than cases among children) registered in 1990.

The researchers found that for men under 65 and for women under 50, having excess weight for over a decade was linked to a 25-60% increase in cardiovascular events such as stroke or heart attack.
This study was conducted during World War II on a group of lean men, who restricted their calorie intake by 45% [14] for six months and composed roughly 77% of their diet with carbohydrates. [13] As expected, this malnutrition resulted in metabolic adaptations, such as decreased body fat, improved lipid profile, and decreased resting heart rate.
Research backs this up: Young men who consumed more protein while losing weight and on an intense exercise regiment gained about 2.5 pounds of muscle, while the young men who consumed less protein ...
If too much weight is gained, serious health side-effects may follow. A large number of medical conditions have been associated with obesity. Health consequences are categorised as being the result of either increased fat mass ( osteoarthritis , obstructive sleep apnea , social stigma) or increased number of fat cells ( diabetes , some forms of ...
