The seasons change throughout the year, everyone’s enthusiasm for weight loss has never faded, but also throughout the year are also in weight loss, we often say “three layers of small belly is not a day of greed”, some people are not just simply because of diet and obesity. But the weight base is larger fat friends, in general, the daily routine should be the lack of regular exercise. Thigh muscles are relatively weak. And running, climbing this type of exercise, is a self-weight training against gravity, that is to say, the greater the weight, the need for more powerful muscles and bones to withstand and cushion the impact generated when the foot hits the ground. In addition, obese people due to self-weight, knees withstand greater force, itself is a higher incidence of osteoarthritis of the knee people. It was found that overweight individuals with a BMI of 25-29.9 kg/m2 and obese individuals with a BMI ≥30 kg/m2 had a significantly higher incidence of knee osteoarthritis than those with a normal weight (BMI <25 kg/m2). The study showed that overweight and obese patients had a risk factor of 2.4 and 3.2 for the development of knee osteoarthritis, respectively, compared with those of normal weight. A very important reason for the development of knee osteoarthritis is the uneven force on the joint, which causes cartilage damage. Studies have pointed out that the articular cartilage damage index is closely related to body mass index, and the degree of articular cartilage damage in obese patients (BMI ≥ 30 kg/m2) is more than twice that of non-obese patients. Too fat and go running, have been running, very big possibility is that the weight loss has not yet succeeded, but the knee has begun to rebel. Knowing this message, then weight loss is an imperative act for fat people. How can you lose weight effectively and without hurting your joints? According to Dr. Dai Xiaojiang, director of bariatric and diabetic surgery at Youdao Group, fat people with a BMI of ≥28 should not do exercises such as running, squatting, and jumping rope, etc. When doing such exercises, the pressure of the body weight on the joints increases, which can easily cause damage to the joints. Suitable for obese people are mainly swimming, the buoyancy of the water will share the body's self-weight, but also exercise the whole body muscles; and Pilates, sitting dumbbell exercises and other sitting exercises, although these exercises consume small, but at least will not cause damage to the joints. To remind those with a BMI ≥ 32.5 fat friends, the traditional weight loss methods are difficult to restore your weight to normal, eat less and move more four-word secret has been less applicable to you, not to mention other types of "folk" weight loss. In recent years, more and more obese patients are undergoing bariatric surgery, and have achieved good results. Bariatric surgery is not only effective in reducing the patient's weight, but also in improving and alleviating the comorbidities associated with obesity. By addressing the root cause of food intake and nutrient absorption, bariatric surgery not only reduces weight, but also treats a variety of metabolic diseases associated with obesity. On average, 60-80% of excess body weight can be lost in one year. And by changing the structure of the gastrointestinal tract, obesity can be eliminated from the root, and the long-term regain rate is only 5-10%. The surgery has a history of more than 60 years and hundreds of thousands of successful cases, so fat people can rest assured.
