Weight gain, or þyngdaraukning in Icelandic, refers to an increase in body weight. This typically occurs when energy intake, primarily from food, exceeds energy expenditure. The body stores the excess energy as fat. Several factors can contribute to weight gain, including dietary habits, physical activity levels, genetics, and medical conditions.

Diet plays a significant role, with diets high in calories, unhealthy fats, and sugars often leading to surplus energy consumption. A sedentary lifestyle, characterized by low levels of physical activity, further exacerbates this by reducing the amount of energy the body burns. Genetics can influence an individual's metabolism and their predisposition to storing fat.

Certain medical conditions, such as hypothyroidism or Cushing's syndrome, can also cause weight gain. Additionally, some medications, including certain antidepressants and corticosteroids, may have weight gain as a side effect. Hormonal changes, particularly during pregnancy or menopause, can also contribute to increased body weight. Lifestyle factors like insufficient sleep and chronic stress have also been linked to weight gain. Understanding these contributing factors is crucial for managing and preventing unhealthy weight gain.
