1) Most important, never ever drink calories. Ever. Like Orange juice? eat an orange. Apple juice? Eat an apple. Only ever drink water.
2) Set a drop dead time where you do not eat any calories after a certain time, preferrably several hours before bed. Say three.
3) Eat six to seven times a day. Batch cook something simple on the weekend and chunk it up into capsule meals. Eat every 3 hours. Instant skyrocketing metabolism.
