FORMULAE FOR WEIGHT LOSS
As anyone who has tried to lose weight will know, there are many options available, and most people will often have tried more than one method of weight loss. Basically, weight loss is about burning more calories than you consume. In other words, energy out must be greater than energy in. If you don't use the energy you put into your body as food, then it will be stored, often as fat.
It is important to modify your diet and be involved in physical activities to lose excess weight and maintain the weight loss over the long term. Many people find it difficult to adhere to diets and exercise programs, and if they have lost weight, they often put it back on. Numerous studies have compared weight loss surgery to non-surgical methods of weight loss, and have shown surgery to be the most effective and sustainable method of weight loss. Most weight loss surgeons however, would recommend surgery be combined with a healthy diet and lifestyle, which includes physical activity, for maximum weight loss.
DIET AND EXERCISE
Regular physical activity combined with healthy eating habits is the most efficient and healthy way to control your weight. Physical activity helps to control your weight by using excess calories that otherwise would be stored as fat
Most available weight-loss medications are "appetite-suppressant" medications. Appetite-suppressant medications promote weight loss by decreasing appetite or increasing the feeling of being full. These medications decrease appetite by increasing serotonin or catecholamine - two brain chemicals that affect mood and appetite. Prescription weight-loss medications should be used only when there is increased medical risk because of your weight and not for cosmetic reasonsSURGICAL PROCEDURE
Gastrointestinal surgery for obesity, also called bariatric surgery, changes the normal digestive process. The operations promote weight loss by decreasing the quantity and or absorption of nutrients and thereby reducing the calorie intake. Some of the common bariatric surgeries include:
In this procedure, a hollow band made of silicone is placed around the stomach near its upper end, creating a small pouch and a narrow passage into the larger remainder of the stomach. The band is then inflated with a salt water solution. It can be tightened or loosened over time to change the size of the passage by increasing or decreasing the amount of salt solution.
Sleeve gastrectomy, also referred to as tube gastrectomy, involves removing the lateral 2/3rds of the stomach with a stapling device. It can be done laparoscopically (keyhole surgery) but is not reversible. It basically leaves a smaller stomach tube of 150-200mls volume, instead of a larger stomach sack of up to 1.5 litres volume.
Here a small stomach pouch is created to restrict food intake. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). This bypass reduces the quantity and absorption of nutrients and thereby reduces the calorie intake.
COMPARING METHODS OF WEIGHT LOSS OVER TIME
Many large studies consisting of thousands of patients have been performed throughout the world in the last 2 decades. These studies compared the amount of weight lost following a surgical procedure, compared to the amount of weight lost with dieting and exercise alone. These studies have shown that surgery is the most effective and durable method of weight loss.
