Personally, I've only done intermittent fasting, like 18-24 hrs, it cleanses the body and it's not too demanding. I know relatives who have done extended fasting, for specific health problems and it has done wonders for them. But if you just wanna get in shape I'm not sure you wanna do extended fasting.
I think strength training would be better to get rid of a dadbod. I recommend something like Reg Park's beginner 5x5, Stronglifts 5x5, or Arnie's Golden Six. They are all fairly easy if you get the lifts right technique-wise (make sure you know what you are doing here!), they would get you into better shape and are a better test of willpower. You can still do intermittent fasting on your off days or eat a caloric deficit, you will gain some muscle and lose some fat.
That's just my advice though, you do what you want really.
