Energy intake

Energy intake refers to the amount of calories or energy that a person consumes through food and drinks each day. In scientific terms, it's measured in units called kilocalories (kcal) or joules, and represents the fuel your body needs to power everything from basic functions like breathing and heartbeat to physical activities like exercise. Understanding energy intake is crucial because when it balances with energy expenditure, your body weight remains stable, but consuming more energy than you burn leads to weight gain while consuming less results in weight loss.
