Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable dict...We are surrounded by the word" diet" everywhere we look and listen. We have so easily been attracted by the promise and potential 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 and physically.

Diet products significantly weaken us psychologically. On one level, influenced by diet products, people tend to watch their weight rather than their diet. Diet products make us Jump over the thinking stage and go straight for the scale(秤）instead. All we have to do is to recognize the word" diet" in food labels in the supermarket. On another level, diet products make people believe that gain comes without pain, and that life can be without resistance and struggle. For example, every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results.

The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.

Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the potential harm that comes from using them.
