“Partial weight loss” where only the stomach is pulled in is an illusion.
When you look at social media or surf the internet, you almost always come across advertisements for diets. Some claim that special workouts or supplements can help you burn fat in specific areas, such as your tummy or upper arms, but experts say these are myths.
Can I actually target areas to lose fat, like my belly?
Nick Fuller, who researches obesity prevention and treatment at the Charles Perkins Center at the University of Sydney, says, ``It's simply impossible to choose where you'll lose fat,'' and he breaks down the reasons for this into three points: I explained it.
◆1: The human body is designed to use all fat as an energy source.
Fat stored in the body is stored in the form of triglycerides , a type of fat molecule that can be used for energy. According to Fuller, about 95% of the fat people ingest from their diet is triglycerides, and unused energy that is ingested but not consumed is also converted to triglycerides.
Triglycerides are taken up by
Instead, your body converts triglycerides into compounds called free fatty acids and glycerol , which are transported to your muscles in your bloodstream through a process called lipolysis. This means that the energy supplied to your muscles for exercise comes from all the fat in your body.
This has been shown in several studies. For example, in an experiment in which 40 obese women were asked to either undergo a diet with only dietary restrictions or a combination of dietary therapy and resistance exercise that puts stress on the abdominal muscles, both groups found that The results showed that there was no difference in the thickness of subcutaneous fat in the abdomen.
Mr. Fuller said, ``Studies that claim that it is possible to achieve partial weight loss have had only a small number of participants, and the results cannot be said to be clinically meaningful.''
◆2: The areas where fat is gained and the areas where it is lost are automatically determined.
According to a 2014 study , up to 60% of your waist-to-hip ratio, an indicator of body fat distribution, is determined by your genes. In other words, most of the tendencies such as how fat is gained and where fat is lost are determined from the beginning by genetics.For example, if your parents had a tendency to gain weight and lose weight starting from the face, there is a high possibility that you will become like that as well. It will be.
Gender is also a factor; in particular, women's bodies are designed to store fat for pregnancy and breastfeeding, so while it is easier to maintain fat around the waist and thighs, it is easier to maintain fat around the waist and thighs, while it is less likely to affect childbirth in the face and calves. , arm fat is easier to lose. Additionally, the speed at which fat falls is affected by changes in muscle mass, metabolism, and hormonal balance due to aging, and middle-aged and older men and postmenopausal women tend to accumulate visceral fat in the center of their bodies.
◆3: Commercially available drugs and supplements cannot effectively reduce fat.
There are drugs and nutritional supplements out there that claim to 'reduce belly fat,' many of which are touted as being backed by clinical trials and scientific evidence. However, independent research conducted by third parties does not support such claims.
Fuller led a research team that examined more than 120
◆Conclusion
For these reasons, it has been shown that spot weight loss is not possible, but this does not mean that it is impossible to lose fat in the areas of concern. Instead of losing fat in specific areas, exercise helps maintain muscle mass and burn overall body fat, which can help with long-term shape changes and weight management.
Fuller says, ``Spot weight loss is a myth and we have no control over what fat we lose in our bodies. However, by targeting overall fat loss, we can target fat loss in specific areas.'' 'We can achieve the desired results.'
