The set point for weight regulation can be modified by environmental changes, but the body may revert to previous weight levels if the environmental change is removed.

“so i think there are things we can do to change the set point however that person that doesn't mean that they are cured so if they went back to their other diet if they just went back to how they used to be eating so they're not maintaining this attempt for weight reduction anymore they generally will go back to where they were so it's not that there's a durable resetting of the set point to like flipping a switch and resetting like restarting your you know computer it's more like the set point has been modified because it's in a different environment and as long as you maintain that change you can maintain the effect but if the change goes away then the effect goes away”
