Tips for Fasting?

Anyone do Fasts regularly? I want to start, but i am pretty weak willed when it comes to food. But I got some issues in life i want to deal with and repeated sin I want to get rid of. As I know there are these types of Fasts 3 day no food no water- That won't happen for me at this stage I think it'd be really rough and I wouldn't be able to make it. 21 day Daniel Fast- Definitely won't happen. 40 day super fast(My title)- This is beyond even Daniel fast won't happen for me. Is there other methods? Perhaps I could start with skipping a meal a day or something. And during that would be meal time make my petitions to the Lord? and move from there? I dunno seeing advice tips and tricks.
