Analysis of common misconceptions about dieting rebound, ineffective exercise, and excessive intensity.
Why do women gain weight again after dieting?
Dieting for weight loss is a long-term plan that requires reasonable control of intake, proper proportion of various nutrients, and maintaining good eating habits. Most importantly, consistency is key to effectiveness. Some women are very determined to lose weight, but adopt incorrect dieting methods, eating as little as possible or even nothing at all, resulting in rapid weight loss that harms their health or causes illness. To treat these illnesses, they then need to return to their previous eating habits, leading to rapid weight gain. Other women, while very determined, resort to rigid dieting, experiencing unbearable hunger, insufficient nutrition, dizziness, and weakness, making it difficult to maintain. They give up prematurely after seeing some results, quickly regaining their previous weight. Still other women find it troublesome and, regardless of proportions, only eat small amounts of foods they dislike. This might result in some initial weight loss, but over time, the intake of favorite foods or snacks gradually increases, leading to weight regain. Even if some women successfully lose weight through dieting for a period of time, the admiration from those around them can lead to complacency and a return to their previous eating habits and portions. When they start to gain weight again, they finally think about controlling their diet, resulting in repeated cycles of this pattern and ultimately, weight gain that far exceeds their pre-diet weight. Clearly, dieting requires determination and perseverance. Furthermore, due to the unique physiological characteristics of women, weight gain can occur at any age. Therefore, to maintain weight loss results, dieting must be reasonable. Reasonable dieting is beneficial to the body, not painful, and thus easier to stick to.
***Why is exercise ineffective for some women to lose weight?***
Exercise is undeniably effective for weight loss, and the reasons are easy to understand. However, some obese individuals who have tried exercise have failed. Why is that?
The purpose of exercise for weight loss is to increase metabolism and burn excess body fat. During exercise, the body's metabolic function is very active, and appetite will also increase significantly. If you think that you can eat as usual without restraint because you burn a lot of calories during exercise, you will find it difficult to achieve your weight loss goal. If you eat more than usual due to exercise, you are very likely to gain weight.
Weight loss through exercise doesn't yield immediate results. While exercise burns a significant amount of energy, resulting in the strongest immediate weight loss effect, the body's vigorous metabolism continues for a period after exercise stops-the so-called "aftereffect." This "aftereffect" generally lasts no more than a day. If you consistently exercise daily for a considerable period, weight loss will naturally occur. Some women, due to busy work and housework schedules, exercise intermittently for three days and rest for three days, causing the "aftereffect" to disappear. Increased appetite negates the original weight loss effect, rendering all previous efforts futile. Other women who haven't exercised for years may find it difficult to adapt, failing to meet the required exercise intensity or duration, thus not achieving their weight loss goals despite exercising. Furthermore, exercise for obese women is like weight-bearing exercise for those of normal weight, placing excessive strain on the lower limb joints. This is especially true for middle-aged and older women who may choose unsuitable exercises, increasing the risk of joint injury and forcing them to discontinue their workouts.
Does higher exercise intensity lead to better weight loss for women?
Many people believe that high-intensity exercise burns more calories and leads to faster weight loss, while low-intensity exercise fails to break down fat and burn energy, thus hindering weight loss. However, most women are not accustomed to or suited to high-intensity activities and are therefore uninterested in exercise for weight loss. In fact, in terms of calorie expenditure, endurance is more important than intensity. The higher the exercise intensity, the shorter the duration. When resting, the body experiences a regulatory slowdown in heart rate and calorie expenditure. Calculations have shown that adding half an hour of walking on flat ground daily, without increasing food intake, burns approximately 100 kcal, resulting in a weight loss of 0.5 kg per month and 6 kg per year – a considerable amount. Therefore, higher intensity exercise is not necessarily better for weight loss; slow, steady, and longer-duration exercise is more effective. This is because the body primarily burns carbohydrates in the initial stages of exercise, only gradually starting to utilize stored fat as the exercise duration increases. Insufficient exercise is also detrimental to weight loss; therefore, maintaining a moderate level of exercise for sufficient duration is best. Of course, the intensity of exercise should be determined based on individual circumstances. Young women or women in good physical condition can exercise more in the early stages of weight loss. Once their weight reaches a normal level, they can switch to moderate to low-intensity exercise to maintain their weight. Women who are not in good health or are older can start with moderate to low-intensity exercise and extend the duration of the exercise to achieve their weight loss goals.
Is it true that the longer the exercise session, the better for women trying to lose weight?
In weight loss exercises, regardless of the form, even brisk walking has its limits. These limits are about avoiding overburdening certain organs, especially the heart and lungs. Excessive exertion carries risks. Therefore, each exercise session should not be too long, and a rest period is necessary afterward. During this time, muscle fibers and cardiovascular function can adapt. Thus, the duration of each exercise session should be moderate; as long as the amount of calories burned exceeds the amount consumed, weight loss can be achieved. Especially for those not accustomed to exercise or older women, a gradual approach is crucial. Start with low-intensity, short-duration exercises, gradually increasing the duration until the body adapts.
Why is it that women who replace exercise with physical labor don't lose weight effectively?
Some women work in physically demanding jobs, even heavy ones. Even housework isn't easy, so they believe exercise is only for those with mental labor or leisure time. They feel they're already exhausted from all the work, and exercise might be too much for them. While labor is a form of exercise, it's a passive form of physical exertion. The postures and repetitive movements during labor are necessary for the task. Weight loss exercise, on the other hand, increases energy expenditure to correct the harm caused by passive movement in daily life and work. Therefore, the two are fundamentally different. Although labor does consume energy, the movement it requires is often singular, repetitive, and prolonged. Most labor involves uneven and localized physical activity; for example, some jobs only use the hands, while others require prolonged standing. This results in muscles that develop more and fat accumulation in areas of prolonged activity, while fat accumulates in relatively static areas, leading to an overall disproportionate physique. Furthermore, for most obese women, the passive physical exertion may not be significant, but the fatigue from mental exertion is very noticeable. Therefore, some people believe that they are already very busy and tired from work, so they should be able to lose weight without needing to exercise. However, this is not the case because physical labor cannot replace exercise for weight loss. Therefore, trying to completely replace exercise with physical labor will not be effective.
Does wearing more clothes during exercise help women lose weight?
Some women wear more clothes during exercise to speed up weight loss, believing that this will increase sweating and improve results. However, while sweating during exercise may cause weight loss, this is only temporary water loss. After 24-36 hours, the body's water metabolism returns to normal, and the weight will rebound. Furthermore, effective weight loss exercise requires not only appropriate intensity, duration, and type of exercise, but also comfort to ensure long-term sustainability and achieve both health and weight loss goals. Wearing too many clothes during exercise prevents the body from quickly dissipating heat, leading to poor heat dissipation. Combined with hot and humid weather, this can result in excessive water loss, causing fainting or even coma. Therefore, loose, lightweight, and breathable clothing should be worn during exercise.
***Why do some people experience amenorrhea due to excessive exercise while dieting?***
Some women who exercise for weight loss gradually lose weight, but then experience amenorrhea (absence of menstruation). This is common among young women who are eager to lose weight. Analyzing their exercise patterns reveals that this is because their exercise intensity is too high, leading to an imbalance between energy expenditure and intake. Excessive exercise causes excessive fat consumption, resulting in insufficient estrogen reserves and a decrease in gonadotropins secreted by the pituitary gland. Meanwhile, the levels of endorphins and catecholamines in the blood increase. The combined effect of these factors can lead to the cessation of menstruation. Amenorrhea caused by excessive exercise is usually temporary and reversible. Changing the exercise intensity or increasing nutrient intake will restore menstruation after a period of time. If menstruation still does not return, a gynecologist should be consulted. Regardless of the method used for weight loss, amenorrhea should not be ignored, as prolonged amenorrhea can lead to further endocrine disorders, affecting fertility or causing other illnesses.
