     Diet Coke, diet Pepsi, diet pills, fat diet, vegetable diet. surrounded by the word "diet" everyw we look

and listen. We have so easily 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

(身体上).

     Diet products significantly weaken us psychologically. On one level, we are not allowing our brains to

admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of

fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the  thinking stage and go straight

for the scale c秤) instead. All  we have to do is to swallow or recognize the word "diet" in  food labels.

     On another level, diet products have greater psychological effects. 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. Diet products make people believe that gain comes without pain, and

that life  can be without resistance and struggle.

     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 (营养成分). 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 chemicals 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 medicals. Once we realize this,

we will be much better able to resist diet products, and therefore prevent the psychological and physical

harm that comes from using them.
