Talk to friends or family about your idea to lose weight or go on a diet to get some added support and external motivation. Eat your meals in peace and take enough time to eat mindfully. If you eat more slowly, you will feel fuller more quickly, and try to stop eating before you feel very full - it takes a while for the body to notice that it is full. Plan your weekly meals ahead of time and go grocery shopping with a list. And don't go shopping on an empty stomach, as you'll be more likely to deviate from your list.
