Whenever we turn on the TV or radio, read the newspapers, surf the Internet, we'll be surrounded by the word "diet" everywhere. We have so easily been attracted by the promise of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically（心理上地）and physically.
It's obvious that diet products weaken us psychologically. They allow us to jump over the thinking stage that our weight problems lie not in actually losing the weight, but in controlling the consumption of fat. All we have to do is to swallow or recognize the word "diet" in food labels.
What's more, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves that we don't have to work to get results．Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
As a matter of fact, the danger that diet products bring not only lies in the psychological effects they have on us, but also in the physical harm they cause. Diet foods and diet pills contain zero calorie. oaly because the diet industry has created chemicals to produce these wonder products, And they can indirectly harm our bodies because consuming them instead of healthy foods means we are stopping our bodies having basic nutrients. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.
Losing weight lies in the power of minds, not in the power of chemicals. Think twice before buying diet products. Once we realize this, we will be much better able to resist diet products, 3rd therefore, prevent the psychological and physical harm that comes from using them.
