Weight loss rebound has always been one of the inevitable topics in weight loss. I believe that many people have had the experience: hard work to adhere to diet, exercise for several months, finally the weight loss to their ideal state, they began to pay less attention to diet and exercise, relaxed on their own requirements, the results after a period of time a weight, but found themselves back to the state before the weight loss, so they had to start their weight loss program again …… This cycle of weight loss – re-fat – weight loss again is also known as the “yo-yo effect” and is an inappropriate way to lose weight. The weight loss process is like playing “yo-yo” in general, weight “up and down”, can not reach the intended goal, so he became a very difficult to “lose weight” physique. Many studies have found that this type of dieting is very easy on the self-confidence of the dieter, and many people will gradually give up losing weight in this cycle, making weight loss out of control. At the same time, the weight fluctuations caused by this type of weight loss will also affect the incidence of a variety of diseases, and its harm may be greater than obesity itself. In recent years, after a large number of case comparisons, many experts have found that, compared to obesity itself, weight fluctuations can also increase the incidence of many diseases, especially cardiovascular diseases. In a study published in the New England Journal of Medicine, it was found that the risk of coronary heart disease, cardiovascular disease and stroke was significantly higher in people with higher weight fluctuations than in people with stable weight, and the risk increased with the increase in weight fluctuations. Many studies in China have also found that weight fluctuations increase the load on the heart, the pancreas and other organs, and that people with frequent weight fluctuations are more likely to develop heart disease and type 2 diabetes, hyperuricemia, endometrial cancer in postmenopausal women and other diseases. In an article in the Chinese Journal of Diabetes, it was stated that people with greater weight fluctuations are more likely to gain weight and have more difficulty losing weight. And it also affects the probability of developing a variety of diseases. For example, people with lower weight fluctuations have a lower risk of developing hyperuricemia, and people with higher weight fluctuations have an increased risk of developing type 2 diabetes. Also, weight fluctuations can lead to an increased incidence of endometrial cancer in women, indicating that weight fluctuations may also affect the incidence of tumors. Although there is no definite conclusion on the effect of weight fluctuation on the risk of various diseases, there are data that show that weight fluctuation increases the probability of developing some diseases, so we need to pay enough attention to it. The causes of weight fluctuations can be attributed to two things: one is the use of the wrong weight loss method; the second is not to stick to the weight loss, after reaching the weight loss goal began to relax themselves. Choosing the right weight loss method depends on the person, everyone’s situation is different, only to find the right weight loss method to effectively lose weight and stick to it. And more importantly, it is important to strengthen the awareness of weight loss and healthy living. Fat is accumulated little by little by the usual poor living conditions, only to strengthen their own health management awareness, the weight loss into a habit, in order to effectively prevent re-fat, but also to avoid the possible harm brought by weight fluctuations. For moderate or severe obesity fat friends, if you try a variety of ways to lose weight is still ineffective, you may wish to consider weight loss surgery, which can effectively reduce excess fat 60-70 percent, for obesity caused by metabolic diseases such as: diabetes, sleep apnea syndrome, polycystic ovary syndrome, fatty liver, etc. have treatment and control effect.
