As per a study being published in the Journal of the Academy of Nutrition and Dietetics, it has been revealed that people, who have been thinking of losing weight and are quite serious about it, should maintain a food diary.

A group of study researchers from the Fred Hutchinson Cancer Research Center in Seattle reached at the above given result, after conducting an experiment on 123 people, who were considered to be obese. All the enrolled participants were females, who aged between 50 and 75.

The total number was divided in two groups, as one of the groups was asked to perform exercise with control diet and other group was asked to have controlled diet and maintain a food diary. Though both the groups performed well, the group which had food diary was able to lose 6 more pounds.

The study researchers were of the view that if people would maintain food diaries then they will able to know about what things they have been consuming. This will help them to decide what to consume and what not to.

"When they went through the process of doing their journals and met with a dietitian, they were really surprised at how many extra calories they were taking in", said study researchers.
