Hello Lisa,
I hope you've moved forward with your diet plan.
Here are some tips that I follow:
- Getting enough sleep, about 7-8 hours a day.
- Getting the proper nutrition based on your target weight and whether you need to lose, gain, or maintain your weight.
- Exercising & doing some strength training to maintain a proper metabolic rate.
There's also this article that I've recently read about increasing your metabolic rate
