If corn is eaten in moderation at night on an empty stomach, it can generally help with weight loss. If corn is eaten after a meal, occasional consumption will have little effect on weight, but long-term this may increase the risk of obesity. Switching your main meal to a moderate amount of corn in the evening is better for weight loss. Because corn is a coarse grain, its fat content is low, generally lower than the daily consumption of refined rice and flour. In addition, corn contains fiber, which can promote gastrointestinal motility, speed up the body’s metabolism and shorten the residence time of food residues in the body. If corn is eaten after dinner and consumed in excess, the possibility of causing obesity will increase if there is not enough exercise to consume excess energy each day. Because the starch in corn will increase the burden of the gastrointestinal tract, and into the body into glucose, excess energy in the body can not be digested and used, it may be converted into fat, in the body accumulation, and then lead to obesity. Due to the high content of dietary fiber in corn, some people may suffer from indigestion, bloating and diarrhea if they eat a large amount of corn at one time. So each time you eat corn is not recommended to eat too much, and people with a weak gastrointestinal tract are advised to eat less.
