There can definitely be a link between stress and weight gain. Certain medications for depression are often linked to weight gain. If this is a concern, talk to your healthcare provider about your medications and their likelihood of causing weight gain. Often times when individuals are depressed, they crave sweets. Sweets can elevate serotonin levels in the brain which can have a temporary calming effect. Unfortunately if this happens often, excess weight will appear. Depression often leads to sluggishness and decreased motivation which can derail any exercise plan. Exercise burns calories and increases endorphins which can help lighten depression.
