How many calories should I eat a day?

To maintain a healthy weight, the number of calories a person should consume in a day depends on various factors, including age, gender, weight, height, and level of physical activity. According to the United States Department of Agriculture (USDA), the average adult needs between 1,600 to 3,000 calories per day, depending on their age and activity level. However, this number can vary widely depending on individual factors, and it is recommended that you consult a healthcare professional or registered dietitian to determine a more personalized daily calorie intake. Additionally, it’s important to note that the quality and types of foods consumed are also important for maintaining a healthy diet.
