Go to bed at a reasonable hour each night. Normally, eight hours of sleep for an adult is recommended. An adequate amount of good quality sleep actually helps you lose weight. Having enough sleep can help your metabolism get corrected so that you can burn your food.
One trick to try while dieting is to leave the food dishes in the kitchen, prepare your plate and then bring your meal to the table. With the food in the kitchen you will be less likely to eat seconds since the extra food is not sitting in front of you while you are eating.
