I think you are going about it the right way, baby steps. A lot of people, especially at the start of a year (resolutions) go like gangbusters for a few weeks, and then get sick of it.
And I agree with Chris, at least with how my metabolism seems to work too, having longer lasting exercise sessions seems to do more for me then short more intense ones. For example, if I went to the gym and burned say 300 k/calories in an hour, but “gardened” and burned off 300 k/calories over 3 hours, the 3 hours seems to work better overall.
And yeah “diets” really don’t work in the long run, you have to gradually make lifestyle (food) changes and weed out the junk.
It’s hard for sure. One day I won’t be obese, I will be just overweight š
