Many
sugar cravings stem from a blood
sugar imbalance. When your body ingests
sugar, your blood
sugar spikes and your body releases insulin to lower it to a safer level. If the insulin brings your blood
sugar level a bit too low, as often happens, your body craves foods that will raise it and increase your energy.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. 5 In a sense, reaching for sugary, carbohydrate-rich foods can be a way of self-medicating depression.
