When I was a kid, I hated dishes that contained a lot of ingredients. I didn't care if different foods touched each other, but I'd rather eat things separately than all mixed up. This frustrated my dear mother very much, and she would shake her head and say 'but it all ends up in the same place!' So, many years later, with that in mind, as long as you're okay with ingredients separately, combining them should have no effect on weight loss. Unless of course you make something so delicious that you eat more than you intended to!
