Diet & Beauty – Weight loss
Weight loss is the loss of total body mass as a result of efforts, to improve fitness and health, or to change appearance through slimming.
Weight loss is achieved by adopting a lifestyle, in which fewer calories are consumed than are expended. According to the UK National Health Service, this is best achieved by monitoring calories eaten and supplementing this with physical exercise.
Depression, stress or boredom may also contribute to weight increase, and in these cases, individuals are advised to seek medical help. A 2010 study found that dieters who got a full night’s sleep lost more than twice as much fat as sleep-deprived dieters.
Weight Loss Techniques
The least intrusive weight loss methods, and those most often recommended, are adjustments to eating patterns and increased physical activity, generally in the form of exercise. The World Health Organization recommended that people combine a reduction of processed foods high in saturated fats, sugar and salt and caloric content of the diet with an increase in physical activity.
An increase in fiber intake is also recommended for regulating bowel movements. Other methods of weight loss include use of drugs and supplements that decrease appetite, block fat absorption, or reduce stomach volume.
Virtual gastric band uses hypnosis, to make the brain think the stomach is smaller than it really is and hence lower the amount of food ingested. This brings as a consequence weight reduction. This method is complemented with psychological treatment for anxiety management and with hypnopedia. Research has been conducted into the use of hypnosis as a weight management alternative.
Long-term Weight Loss
In order for weight loss to be permanent, changes in diet and lifestyle must be permanent as well. There is evidence that counseling or exercise alone do not result in weight loss, whereas dieting alone results in meaningful long-term weight loss, and a combination of dieting and exercise provides the best results. Meals replacement, orlistat and very-low-calorie diet interventions also produce meaningful weight loss.
