Researchers believe that having an imbalance of serotonin in the brain contributes to the development of depression. When you're craving carbs, you're usually being drawn to foods that encourage serotonin production. Craving carbs can be your body's way of self-medicating depression.

Over time, a high-sugar and carbs diet may worsen symptoms of depression (especially if you tend to feel guilty about having or "giving in" to cravings).

Here's why you might be suffering from "chocoholism":

• Alkaloids in chocolate may raise the levels of serotonin (the happiness hormone) in the brain.
• Feeling like you need chocolate might indicate you’re not getting enough magnesium in your diet.
• Chocolate also contains “drug-like” constituents such as anandamides, caffeine, and phenylethylamine, which can wield a powerful influence on mood.

There are some ways you can learn to cope not only with cravings but what is causing them:

• Practice becoming more aware of your emotional triggers for eating. The next time you pick up a "comfort food" ask yourself why you're reaching for it.
• Find new activities to replace snacking or distract yourself from cravings, you may want to try using the opportunity to exercise.
• Mindful eating helps you plan meals and snacks intentionally. You may find it useful to keep a food journal to help you track.
