Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… 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 (身体上).
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain
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 (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 calories 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 psychological harm that comes
from using them.
