If you're still hungry, drink some water and wait a few minutes first. Sometimes your hunger pangs are a result of thirst or boredom. Go for a fifteen minute walk and have a glass of water. If you feel like you still need to eat then perhaps it may be time to nourish your body.
Exercise is a great complement to your diet when you are trying to lose weight. This could be squeezing muscles while watching television or when you're sitting at a desk. Contracting muscles helps to burn calories, which will help your weight loss program substantially in the long run.
