There is actually a lot of scientific debate going on right now regarding
SSRI medications and their effect on weight control. Most studies have found that
SSRI meds have not demonstrated any change in the bodies metabolic rate.
Other studies indicate that in some people SSRI's can cause food cravings and over eating, this resulting in weight gain.
It's really weird. Many have posted here saying that their SSRI caused weight loss, while others report weight gain.
