There are a number of different surgical procedures which can lead to weight loss and these include gastric band surgery, gastric sleeve surgery, duodenal switch, gastric balloon, Aspire Assist, and liposuction. The last of these is really only for toning certain areas of the body and will not have a significant overall effect.
However, any form or surgery carries with it some risk, so it is not surprising that the majority of those seeking to lose weight will opt for non-surgical weight loss.
Non-surgical weight loss options will obviously include dieting, and there are countless different diets on the market every one of which claims that their diet is the best and will result in permanent weight loss. Some diets do, of course, work, but the truth is that it can take a lot of willpower, which is why many people who diet and lose weight slip back into their old bad habits and not only put the weight back on, but may put on more than they lost in the first place. They may then go on another diet, and can be on a sort of roundabout for years where they are on and off diets.
There are also weight loss pills and some of these have been regarded as safe, but they can have side-effects. Others that have not been approved can actually contain things that are known to be dangerous.
Another weight loss option without surgery is a form of hypnotherapy and this is claimed to be a permanent solution.
