openheart - Given that you can't set the menu to your needs, I suggest eating smaller portions. Load your plate with slightly smaller meals every day, just so it's barely noticeable. By doing that, you'll eat less and clear out the plate, meaning that you won't have the guilt of not eating it all (or at least that's what I have).
As far as exercises go, you should do whatever you find most interesting, otherwise you'll just get bored of it and stop doing it. If you love cycling, hop on a bike and do 5 or 10 kilometers to start with. You'll just increase it gradually. I'm confident that you can do it!
Amazon D - While the described diet may be effective short-term, it's not going to help on the long run. Once you return to your normal meals, you'll gain weight back to the same level, if not even more. Apart from that, the diet is awfully unhealthy as you're not providing your body the vitamins, carbs, fat and calories it needs. By starving yourself out, you're only going to make it harder for you to lose weight because your body will start saving every possible calorie to preserve energy. Losing 1-2 pounds a week is healthy, losing 10 pounds in less than two weeks is very unhealthy. Losing weight slowly will make you keep it down, as well, because you get used to the smaller daily intake.
