The saying “the road ahead is the one you choose” is also very appropriate for weight loss. Weight loss surgery gives patients a chance to lose weight and develop good eating habits. How the patient chooses to live and develop eating habits during this time is crucial. This is because the choices made during this time may benefit the patient for the rest of their life, or they may sharply diminish the effects of the surgery. Some patients feel that they are eating less to “prevent their bodies from collapsing” and try to supplement their bodies. Not allowed to drink carbonated drinks on drinking freshly squeezed fruit juice, pulsation; meals do not eat, eat more meals; meals eat less, grab a few handfuls of melon seeds to supplement snacks, although the amount of food is not as good as before, but the effect of weight loss is not obvious, because it may be eaten and not quite a lot. There are also patients who are afraid of “white knife” strict control of calorie intake, skillful selection of low-calorie food, not only careful control of calorie intake, at the same time strengthened exercise, to ensure that to achieve a better effect of weight loss. I hardly recognize such patients when they come back for six-month follow-up. With a normal diet, surgery can lose up to 80% of the excess weight, but the “expiration date” of the surgery is three to five years or a lifetime, depending on the patient’s lifestyle and diet. Weight loss surgery only gives obese patients a chance to be “born again”, whether to seize it to live again, or to repeat the same mistakes, depends on the patient’s cooperation and dietary control.
