A food diary is a record where individuals write down everything they eat and drink over a specific period. This tool helps people track their dietary habits, understand their nutritional intake, and identify patterns in their eating behavior. It can be useful for those looking to manage their weight, improve their health, or meet specific dietary goals. Typically, a food diary includes details such as the type of food consumed, portion sizes, and the time of day. Some people also note their feelings or hunger levels, which can provide insights into emotional eating. Using a food diary can promote mindfulness about food choices and encourage healthier eating habits.
