Antidepressant medications have helped millions of people cut through the dark fog of depression. Many others try these medications but stop taking them, often because of side effects such as weight gain. A new Harvard-based study, one of the largest and longest studies of the connection between antidepressant use and weight so far, shows that the amount gained is usually small, and that it differs little from one antidepressant to another. Using citalopram as a reference, because earlier studies suggested that it is “average” when it comes to weight gain, bupropion was associated with the least amount of weight gain, close to none. Two others that also appeared to have relatively less weight gain were amitriptyline and nortriptyline. At the other end of the spectrum, citalopram caused the most weight gain. Even so, the differences between the drugs was small. The results of the study were published online this week in JAMA Psychiatry.
By offering the taste of sweetness without any calories, artificial sweeteners seem like they could be one answer to effective weight loss. The American Heart Association (AHA) and American Diabetes Association (ADA) have given a cautious nod to the use of artificial sweeteners in place of sugar to combat obesity, metabolic syndrome, and diabetes, all risk factors for heart disease. As with everything, there’s more to the artificial sweetener story than their effect on weight. One concern is that people who use artificial sweeteners may replace the lost calories through other sources, possibly offsetting weight loss or health benefits. It’s also possible that these products change the way we taste food. Research also suggests they may prevent us from associating sweetness with caloric intake. In addition, the long-term effects of artificial sweeteners on health have not been fully determined.
