I eat very unhealthy fods. how do i start cleansing and dieting?

Unhealthy?: Why? Many of the less healthy food choices often taste better and are more satisfying. Making better choices means finding foods that are healthier, and equally satisfying, or choosing to eat foods that are less satisfying. You have choices when going out as well, choose the restaurants that offer healthier foods, smaller potions, more fruits and vegetables. Cut down on carbohydrates.
