subject: Dieting [print this page] Obesity results from the interaction of many factors in genetic, metabolic, behavioral, environmental and lifestyle influences. The basic principle behind weight gain is defect/imbalance in energy homeostasis. i.e.; lack of proper dieting. As a result the excess energy is stored in the body and the fat cells increase in size and number.
In a study in the University of New South Wales, animals were offered cafeteria diets (chocolate bars, cheese curls, cookies etc).These animals became obese and began to refuse their natural food .Even more starling, they began to eat these food items even when they were not hungry. Junk food thus has been proved to have the ability to develop fakehunger leading to repeated eating and obesity
Over the years the average fast food consumption and portion sizes has increased.
Ready access to inexpensive snacks, drive through and quick delivery, the popularity of buffet dining, television advertising of unhealthy foods, school contracts with soft drinks and other junk food companies reflects the double edged sword of technological advancements as these can have disastrous effects on our body.
There is a clear decrease in traditional three meals a day pattern and a rise in more frequent, less formal eating occasions commonly described as snacking. While the eating frequency per se may not contribute to obesity patterns, the quality and quantity of these snacks have severe impact on individuals. Studies have shown that consuming increasingly large packets of chips or sandwiches during these snacking is associated with significant increase in appetite and the individual ends up consuming large quantities during the subsequent meal.
Contrary to popular assumption dieting does not refer to starving yourself off calories and cutting out any traces of carbohydrates and fats. In fact when youre dieting youre not expected to give up on any kind of, you only have to cut down on the size of the portions.
An obese person who is dieting is encouraged to have around 1500-1600 Kilo calories a day. This diet should have a major contribution from proteins, vitamins and minerals and less contribution from fats and carbohydrates.
Fats and carbohydrates should never be cut out from the meals as is common among most diets popular on the net. Deficiency of fat may lead to loss of lean muscle which in turn to many health disorders. Also cutting out carbohydrates drains you of energy which only prevents you from exercising and makes you hungrier.
