Keep a food and weight diary

Self-monitoring is a critical factor in successfully losing weight. People can use a paper diary, mobile app, or dedicated website to record every item of food that they consume each day. They can also measure their progress by recording their weight on a weekly basis. Those who can track their success in small increments and identify physical changes are much more likely to stick to a weight loss regimen. People can also keep track of their body mass index (BMI) using a BMI calculator.
