Weight loss happens in a similar way whether you risk the dangers of gastric band surgery or go it alone, losing weight naturally through adjusting to a healthier lifestyle, diet and exercise. After you have had gastric band surgery you still have to adjust the foods you eat and drastically reduce the portion sizes. So why not just do that, and lose weight naturally, instead of subjecting your body to the trauma of surgery?
A better question to ask yourself is what has stopped you from losing weight successfully? Or perhaps what changes when you undergo gastric band surgery? The answer of course boils down to the fact that once you have had this type of weight loss surgery you quite simply cannot eat more than small quantities of food; it becomes physically impossible.
And so even if you want to eat more, you cannot. In short, you do not have to have the will power to stick to a diet or pursue an exercise regime or to change your lifestyle when you have had this type of surgery. But the fact remains that your lifestyle does indeed change. You do alter the way in which you eat and the way in which you socialize. All this still has to happen, with or without the gastric band.
