Weight Loss

Last updated:

Weight loss is the process of decreasing total body mass. While intentional weight loss to cut excess body fat has many health benefits, losing too much weight can have negative effects on health.

The process of losing weight can be the result of an intentional effort by the person, or it can be unintentional, which may be a cause for concern.

Weight loss is more commonly associated with intentional weight loss, as people generally want to reduce their body fat levels either to improve their health or to achieve a certain appearance, or both. Although weight loss is generally thought of in a positive way, there are cases where a person may be losing weight unintentionally. In these cases, underlying health issues may be the cause for weight loss, and it can lead to further health complications if left untreated.

Losing weight is a term used to describe when the body mass of a person decreases. While weight loss is commonly associated with losing fat, the truth is that it may also be due to the loss of muscle mass, body fluid, bone minerals, and other tissues. Some intentional weight loss programs aim to reduce body fat while minimizing the loss of lean mass. 

Many techniques have been developed for people who want to intentionally lose weight. The most common techniques involve dietary changes and increased levels of exercise. These types of programs are generally regarded as the best way to lose weight because they are typically in line with a healthy dietary and fitness regimen. 

The success of dietary weight loss programs derives from the fact that they are generally based on scientific evidence that the body loses weight when it burns more calories than it consumes. The body makes up for the calorie deficit by using the energy stored in fat tissue, which leads to a decrease in body fat levels. As a result, many programs use tools like a weight loss calculator, a weight loss percentage calculator and a body measurement chart to aid people who are interested in losing weight. They also typically make a recommendation for how many calories you should eat to lose weight.

While eating fewer calories to lose weight is a common practice in most dietary programs, many of them set unsustainable goals. These are generally referred to as crash diets. Although they may be effective in the short term, they commonly lead to people regaining weight in the long term. People that are seeking for the fastest way to lose weight typically follow crash diets, even though they are aware they are not necessarily the best option. Crash diets are easy to identify as they commonly use attention-grabbing headlines such as “how to lose weight fast for men” or “how to lose weight in a week”. Unfortunately, the weight rebound effect after a crash diet has profound psychological effects on the person, as they may falsely believe that they simply can't lose weight. In fact, some of the most popular searches on Google include “why can't I lose weight and keep it off” and “why I put on weight again”.

Successful dietary programs for losing weight pay close attention to macronutrient intake, as it is crucial for the body to receive the proper nutrients on a daily basis. General guidelines establish daily intake recommendations for carbohydrates, protein, and fats. The most successful dietary programs slightly restrict calorie intake, typically in the form of carbohydrates, while still ensuring that the person consumes the minimum daily nutrient requirements.

Professional bodybuilders take the science of weight loss to the extreme as their goal is to reach the lowest levels of body fat percentage possible. Although it is proven to be an unhealthy practice, bodybuilders even go so far as to follow methods on how to lose water weight, so they can appear even leaner in competition events. 

Other techniques for losing weight include surgical procedures, psychological treatment, and dietary supplements. However, they are not recommended because they are not as safe and effective as programs that combine healthy eating habits with increased exercise.

Surgical procedures are also available for people who want to lose weight. Common procedures include gastric bypass and gastric banding which alter the digestive process by restricting how much food a person consumes before they feel full. However, these types of techniques are not without risk, as they may lead to health complications.

Dietary supplements may also be used to decrease appetite or to prevent the body from absorbing fat. However, they are considered unhealthy and they are not an effective solution in the long term.

Psychological treatment options include hypnosis therapy and anxiety management therapy. They are typically used in conjunction with other techniques, to reinforce the success of the weight loss program.

Underlying health conditions may also be the cause of unintentional weight loss. Diseases such as cancer, AIDS, cardiac disease, renal disease, and gastrointestinal disorders are frequently associated with weight loss.

Other unintentional causes may include malnutrition, which can result from the lack of access to food or the inability to purchase it. People who suffer from depression may also inadvertently eat less than their body needs, leading to weight loss. Some medications and medical treatments have also been associated with the loss of body mass as they may reduce a person’s appetite or affect the body’s digestive system. 

Excessive weight loss can lead to serious health complications. A healthy body fat percentage range is between 15% and 20% for men and between 20 and 25% for women. However, if the body fat percentage drops too low (below 3% for men and 13% for women), bodily functions will start to fail, which can ultimately lead to death.

When in nutritional deficit, the body obtains its energy from body fat. However, if the body fat percentage is too low, the energy is obtained by breaking down muscle tissue instead. The loss of muscle and bone tissue and the slowing down of the metabolism are common side effects of excessive weight loss. Taken to the extreme, other health complications can include organ failure and heart problems.
