In order to lose weight successfully, you need a food journal; the more comprehensive it is, and the more you document, the more you will be successful.
Recent studies have shown that if two groups of overweight people go through the same lifestyle intervention, the group that documents all their intake on a daily basis, and then has the information reviewed on a weekly basis, will end up losing more weight in the short-term, and will keep more weight off in the long-term.
So, the key message is a Food Journal, it is a must. It should be reviewed by your Obesity Coach weekly. The more comprehensive your food journal is, the more successful you will be.
