This “vulnerable” time may be influenced by a number of different factors: low energy levels, high stress levels, the feeling of being over worked and the need for recompensing, the feeling of deprivation after a very low calorie day, etc. If you can identify your most vulnerable time during the day and understand what influences the strength of the cravings, then you are one step close to being able to handle even the toughest of temptations.
One of the best tools for helping you to ID what emotion or situation is influencing your eating and food decisions is a food journal. Tracking not only what and how much you eat, but including information about how you are feeling (emotions like stress, sadness and boredom) or whats happening around you (getting dinner together while helping the kids do their homework, or sitting at desk working on a report that is late) can give you valuable insight as how they influence your eating. Patterns may emerge and by understanding what to do to avoid being in a potential trouble situation can make things a lot easier.
Sometimes ignorance is not bliss, and understanding when your vulnerable time is, can help you manage your health and cut down on emotional eating.
