If you want to lose weight, it means "keep your mouth shut and open your legs", but girls who lose weight through exercise will struggle with one thing: why do they gain weight after starting exercise? This starts with body composition and weight loss goals. Everyone knows that weighing scale can be used for weighing. But what exactly is weight made of? I'm afraid many people haven't thought about it. There are bones, muscles (including visceral muscles and limb muscles), blood and lymph, and fat. What are the body components of each of the above categories and their proportions are called "body components". Who wants their bones to be too light? Strong bones are a great health advantage. Low bone weight often means the risk of osteoporosis. Who wants too little muscle? Decreased visceral muscles mean decreased metabolic function; Muscle loss of limbs means physical weakness and physiological aging. Generally speaking, the attenuation of muscle is directly related to the decline of metabolic rate, that is, the reduction of energy consumption will make people form a constitution that is "easy to gain weight but difficult to lose weight". Who wants too little water in his body? Blood and lymph are extremely important to human health, and the water in the body is also closely related to the youth of the human body. Babies have the highest body moisture, while the elderly have the lowest body moisture. Knowing these basic principles will make us understand that when we lose weight, we have to lose fat, not bones, muscles and body water. Only too much fat will bring us the risk of illness. Reducing the proportion of body fat to a reasonable range is the real weight loss. If we only pursue weight loss without reducing the proportion of body fat, or even reducing useful parts of the body such as bones and muscles, it will ruin our health, accelerate our aging and reduce our metabolic rate, which is contrary to the goal of weight loss. Then why does exercise to lose weight increase weight? For people with poor physique, exercise not only consumes fat, but also strengthens the function of internal organs and increases the proportion of muscles in the body composition. But the proportion of muscle is larger than that of water, and the proportion of fat is smaller than that of water. If a dieter loses 1kg of fat, but gains 1kg of muscle, then weight gain will inevitably occur. This situation is most obvious in the early stage of exercise. When the metabolic rate returns to a higher level, the fat man's ability to decompose fat will be enhanced, and then he will see a slow but sustained weight loss. A lady said that after she started exercising for two months, she gained 4 Jin, but after putting on clothes, she obviously felt in good shape. Jeans that she can't wear can be put on beautifully, and her waist is thinner, her abdomen is flatter and her hips are upturned. This is a result of losing weight that should be extremely happy, because it means that almost all the fat she lost is fat. Only the weight loss with reduced fat rate is the real weight loss, and it is the weight loss that makes the body beautiful. However, most girls are not in this mood. A girl asked: why did I work hard for two months, and my body really became thinner, but my weight did not drop? I am so depressed! But have you ever thought that if you go on a diet for two months and lose a few pounds, and your figure doesn't get better, will you feel happier? Unfortunately, most people are depressed because they forget the fundamental goal of losing weight and can't see the effect of losing weight in the early stage of exercise, which in turn makes the great cause of losing weight give up halfway. Some people will ask: exercise can really change my body shape, but once I stop, I will rebound! Yes, but wouldn't it be better to lose weight in other ways besides exercise? -Stop exercising and go on a diet? Can you be hungry for life? As long as you stop dieting and eat three meals, your weight gain will be faster and more terrible. -don't exercise, change to medicine? Can you take diet pills for life? The so-called three-point poison, all diet pills have obvious side effects, and so far there is no panacea that can make people lose weight without paying any price. In contrast, exercising three times a week is extremely beneficial to health, vitality and beauty. Why not take fitness as a habit and stick to it? After staying away from youth, until the age of 70, with the growth of age, the metabolic rate gradually declines, and the human body will become more and more prone to gain weight. Keeping a healthy figure is a lifelong career. Don't be eager for quick success and short-term behavior, thinking that you can "finish it in one battle".
