There is a clear difference between becoming fit and staying fit, no? Overweight depressed and no prior sports history to fit can easily take a year of hard work. Maintaining basic fitness (not big gym bill or 21k in 90 min fit, but regular happy fit) and a healthy BMI is really just adapting lifestyle and not even having to work out. Walk to the groceries, walk during lunch and f.e. when calling with friends. All true that these last examples are all adaptations of a healthy lifestyle, which I expect to be harder to adapt to for those with mental health issues.
