Sorry - I think there's complexity with insulin at play that you're overlooking. When I did caloric restriction, I was constantly battling hypoglycemic events that made me not want to exercise. I don't get that with the GLP-1s. In online discussions, people tend to conflate GLP-1 with appetite suppressants - but there's also insulin stabilization that occurs.
Exercise to the extent that obese people will do usually does not a very sizable impact on weight compared to the effect of proper diet, and weight loss is very achievable with zero exercise.
