Why Does Wellbutrin Cause Weight Loss?
I think it depends on the person, as SpecialK intimated, and here’s how: Some people eat more when they are depressed, because food=comfort. Take wellbutrin, stop being depressed, eat less, exercise more as a result (and, by the way, have more sex–wellbutrin is good for that, too), and you lose weight. Some people gain weight on wellbutrin because these are the people who DON’T eat comfort food when they are depressed, the people who instead sleep a lot, or just don’t eat. Once they feel better, they go back to their usual habits.
I think that Wellbutrin has a tendency to reduce addictive cravings in people, which is why it is also marketed as Zyban to help people stop smoking. It also is one of the few ad’s that perks people up, whereas most of the common antidepressants make people kind of sleepy or lethargic. Being perky burns more calories than laying in bed staring at the ceilinig.
