It doesn't need to be expensive. Be creative and use things freely available to you. Also, as Klloydmajestic has already mentioned, 'you don't need the supplements'. Well balanced meals will provide the nutrients and energy you need for a healthier you. So your meal in conjunction with regular exercise should give you some results provided that you are eating a deficit. That is you are burning more calories than you are consuming. I think that naturally when you become active you eat more but keep in mind to eat burn more than you are eating. Some people also find that it helps to eat a lot of smaller meals throughout the course of the day - say 6 or so.
