I think having too much information can be worse than having none at all. I agree very much with Goldfinch: experiment and see what works for you.
Other than that, I will just add that whatever plan you come up with has to be something you can live with long term if it's going to really work. If you don't like the food you eat and the activities you do, you won't stick with them.
And I think it's easier to make lifestyle changes when you make them one at a time, so you can incorporate one change into a new habit and then after a couple of weeks try changing something else. This won't necessarily lead to "fast weight loss" but gradual weight loss is the kind that tends to stick. And it will help you figure out what works for you and what doesn't.
Good luck!!
