It's hard to exercise when you are overweight. It puts more strain on your joints, makes injury more likely, and it's all around harder.

Maybe there is a path to using these drugs in a manner to get people healthier so they can exercise more, establish good habits and taper down.

Weight gain makes it harder to exercise. In any particular day, eating more also makes exercise harder (because it tanks your energy levels).

This is especially true if you count light exercise.

Oh, no sorry, the study I read had people on Wegovy, but it also had them exercise 2.5 hours per week at the same time.

The point was that the 15% weight lose in a year is in the high end of what you can expect, especially if you change nothing else.

That's probably counting 'light exercise', aka walking around. That works out to 20 minutes a day, so it could just be the side effect of people being lighter and so walking places being more comfortable.
