Calorie balance is the most important element in weight loss. As the Centers for Disease Control and Prevention puts it: “If you are gaining weight, you are eating more calories than your body is using.” Calories play a big role in controlling your weight. There are hundreds of dieting strategies with various relationships to caloric intake; at the end of the day, weight management still comes down to the calorie in and calorie out in your body.
The best ways to decrease your intake of calories are eating less and eating a healthier diet, while the best way to increase your calorie expenditure is exercise.
Generally speaking, though, it is very difficult for most people to stick to their plan of eating less in the long term. Research has shown our brain has a certain "set point" for our body weight that tends not to budge through dieting alone. When we lose weight by dieting, the set point will try to bring the body weight back by shutting down our base metabolic rate to conserve energy, causing us to burn fewer calories. At the same time, dieting makes us feel very hungry. The end results of many dieting attempts leave most people regaining the lost weight — and some regaining even more.
Bariatric surgery is a way in which we combat the difficulties and downsides of dieting — such as long-term adherence and decreased metabolism — while still working to achieve weight loss.
