The Diet Zone: A Dangerous Place
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 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 (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 chemicals.
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.
