Some ideas that have helped me as I plateaued:
1. Vitamins - for some reason, when I take vitamins I don't have cravings for foods with those nutrients and I eat less.
2. Drink water. LOTS of it.
3. Switch up the activities - each activity only works certain muscle groups, so if you change it up frequently you get a better work out.
4. Monitor calories. I use a site: www.fitday.com
5. Make sure to take days off and give your body a rest
6. Try to vary your caloric intake - some days I am as high as 2700 calories and others I am more like 1500 - this roller coaster keeps your body from budgeting to a certain calorie intake.
