How to Keep a Food Journal
- Record everything you eat and drink, including portion sizes, times of meals, and how you felt before and after eating
- Use a small notebook, smartphone app like MyFitnessPal or Lose It!, or even a simple notes app on your phone
- Log your food immediately after eating rather than waiting until the end of the day when your memory may be less accurate
- Include details about your hunger levels (on a scale of 1-10), your emotional state, and any physical symptoms you experience
Reviewing Your Food Journal

By following these steps and keeping a food journal, you can take control of your eating habits and make positive changes to improve your overall health and well-being.
From the Research
Food Journal Overview
- A food journal, also known as a food diary, is a tool used to track an individual's food intake over a specified period of time 2.
- It is a prospective, open-ended survey method that collects data about the foods and beverages consumed, and can be used to estimate current diet and identify groups at risk of inadequacy 2.
Benefits of Food Journals
- Food journals can provide high validity and precision when used following adequate procedures and considering a sufficient number of days 2.
- They can help individuals become more aware of their eating habits and make healthier choices, which can lead to improved overall health and reduced risk of chronic diseases 3, 4.
- Food journals can also be used to monitor progress and identify areas for improvement in dietary patterns, such as reducing saturated fat and refined carbohydrate intake and increasing consumption of fruits, vegetables, and whole grains 5.
Limitations of Food Journals
- Food journals can be affected by error and have limitations due to the tendency of subjects to report food consumption close to those socially desirable 2.
- They can also be time-consuming and burdensome for respondents, and may influence food behavior in order to simplify the registration of food intake 2.
- Additionally, food journals may not be suitable for everyone, particularly those with limited literacy or cognitive abilities, and may require additional support or guidance to ensure accurate and complete recording of food intake 2.
Using Food Journals for Weight Management
- Food journals can be a useful tool for weight management, as they can help individuals track their food intake and identify patterns and habits that may be contributing to weight gain or loss 6.
- By monitoring food intake and making adjustments as needed, individuals can work towards achieving a healthy weight and reducing the risk of obesity and related health problems 6.
- Food journals can also be used in conjunction with other weight management strategies, such as meal timing and macronutrient composition-based diets, to support overall health and well-being 6.
