We really don't all know these.

There isn't anything even remotely close to a scientific consensus on any of those.

There are plenty of scientists who tell you to stop exercising when you want to lose weight, because the exercise leads you to eat more than you would otherwise, and is ultimately self-defeating -- to focus entirely on eating less, and then only add exercise back in once you've reached you target weight. And "processed food" is a highly non-scientific category that is way, way too disparate to be useful at all.

Organic vegetables might be nice, but there's zero evidence that organic vegetables are better at weight loss than non-organic. Also zero evidence regarding lean protein as opposed to fatty -- there's a big argument that fatty meat is better for weight loss, because the fat satiates so you wind up eating less calories overall.
