If you can provider information about your weight training and cardio it will be easier to help you.
The main reason that peole loose weight is because of their diet not because of their workout. Workout helps to loose the right weight - fat. Because when you regularly train your muscles you make you body think that muscles are imortant fot you. When you are on diet you decrease your source of energy and your body produce energy from burning fat or musleces.
As I mentioned above if you use your muscles, your body "thinks" that they are important for your living and starts melt the fat for energy need it for your daily things as breathing, walking etc.
So about eating. You must aet helthy, not not stop eating. Eat every 2-3 hours in order to have something in your stomach and to prevent cravings. The easiest diet I can recommend is grilled (backed) meat with salad (without sauce). Your muscles needs protein food, which is in meat, and salads will give you vitamins and minerals. Try to eat half a pound (200 gr) of meat and salad 5-6 times a day. Add olive oil, salt and vinegar to the salad.
Another tip - if you gain some muscles (because it is very difficult to gain big muscles) they will burn additional energy, and because you use muscles in workout, you will burn aditional energy from fat.
