When you go on a diet to lose weight, once you return to a normal diet, you will soon regain your original weight. Due to long-term dieting, the body's basal metabolism declines, and the consumption of calories will be slower, which makes it impossible to maintain normal operation. However, if you suddenly return to a normal diet and let the body with low metabolism accept a high-calorie diet, it is only a matter of time before you regain your weight. Obese people have too much body fat. When they are beyond the body's carrying range, blood also contains a lot of lipids, including high cholesterol, high triglycerides and saturated fatty acids. Low-density lipoprotein will increase, while high-density lipoprotein will decrease, and the body's ability to transport lipids will decrease.

The increase of blood pressure is definitely not a good sign, mainly because the increase of fat content in body tissue leads to forced contraction of blood vessels, which increases the blood flow back to the heart, indirectly stimulates the pumping function of the heart, and further leads to the increase of blood pressure. Over time, this may lead to damage to other organs of the body. Excess fat in the body will be transported by blood to the liver for treatment. In the liver, fat will be decomposed into other substances, but it will also accumulate in the liver. If the decomposition rate of fat is slower than the synthesis rate, fat will accumulate in the liver and affect the liver function.

Fat metabolites can produce free radicals, which are very harmful to cells and even one of the causes of cancer. If there is too much fat, the body will continue to decompose and produce more free radicals, and the probability of cancer will continue to increase.

The problems brought by obesity are far more than the above six points, but these six points have a great influence on our life and work. We should stop it. In fact, it is not difficult to prevent obesity and lose weight. As long as the method is proper, I believe that good weight control can be achieved. First of all, we should control our diet, quantify each meal regularly, and pay attention to two or more nutritious things at the same time, so as to lose weight scientifically.
