After about 2 weeks, I'm not surprised that you're not seeing results yet. Speaking from experience, losing weight takes a heck of a lot longer than gaining it.
It works a little like this: A pound of weight gained/lost equals about 3500 calories. In order to lose 1 lb a week, you'd have to decrease your weekly calories by 3500 - or 500 a day.
You can do that by decreasing what you eat, or you can do it with exercise, or (ideally) a combination of the two. But you'd have to make sure to CONSISTENTLY burn 500 calories a day by exercising, every single day, to see a difference that way... and even then, that's one pound a week, which is the rate of weight loss recommended by doctors and such, but it's still "slow" weight loss if you're hopping on a scale and waiting to see a real difference.
I would suggest starting to count calories, honestly. I mean, I've seen your menus, and you don't make bad food choices or anything, so I'm guessing some of it might also be portion sizes. Or, as has been discussed here quite a bit recently, maybe you aren't getting ENOUGH calories, which would send your body into "famine" mode and make you not lose weight. There's a lot of variables. But mostly, it really just takes time, so hang in there and try to be as consistent with the exercise as you can.
