There has been much debate on different diets and which work best and how. There is the Atkin's diet, the South Beach diet, the Dukan diet, and many more. The problem is, these diets may help us shed a few pounds in the short run, but studies have shown that dieting may make us fatter in the long run. Dieting Help
New evidence shows that slicing calories alters your brain and your metabolism, causing your body to store more fat when you eat. It also makes your mind go from craving food, to obsessing over it.
Researchers took "50 obese men and women, and coached them through eight weeks of an extreme 500-to-550-calories-a-day diet (a quarter of the normal intake for women)." Dieting or Starving. "At the end, the dieters lost an average of 30lb. Proietto's team then spent a year giving them counselling support to stick to healthy eating habits. But during this time, the dieters regained an average of 11lb. They also reported feeling far hungrier and more preoccupied with food than before losing weight."
Tests on the dieters showed that hormones were working extremely hard, telling the body that it was starving and needed to eat in order to store more fat. "Their levels of an appetite-stimulating hormone, ghrelin, were about 20 per cent higher than at the start of the study. Meanwhile their levels of an appetite suppressing hormone, peptide YY, were unusually low."
Now the correlation between the ghrelin increase at the end of the study may not have been due to the previous strain of dieting because this was an observational study and no variables were taken out. This study could have been much more effective if a variable such as exercise been taken into account. The foods eaten also should have been recorded because they may not have been getting all of their needed nutrients.
The results of the study are due to the evolution and survival of the human race. Humans are able to store much more fat than most other animals when compared pound for pound. Keeping that in mind, dieters need to realize that starving oneself only helps in the short run, but hurts in the long run. Plus there are many other negative effects of too much calorie cutting such as depression, mood swings, and weak immune system as a result of malnutrition.
I have watched as my uncle has struggled with his weight over the years. From being a fit, star wrestler in his younger years, to being over 260lbs. His weight has fluctuated tremendously. He recently put on 20 more pounds after slimming down again. In his early struggles he tried to just diet and my parents said the weight would come back in a few months. Now, when he has combined healthy eating and regular exercise it tends to stay off longer, but when he feels content and stops exercising regularly, he starts to put the weight back on.
To summarize, dieting can end up hurting the body more than helping. The only way to safely lose weight is to exercise regularly and eat healthy (in moderation). If you have any suggestions as to how this study could have been more properly conducted or any other additional information on dieting, inform me in the comments section.
