The blood flow distribution is disordered. After meals is the peak of digestion and gastrointestinal movement. At this time, it mainly involves a lot of blood, but if you exercise, the muscle movement of the whole body also needs a lot of blood, so it is easy to seize the blood volume of digestive organs, and the blood distribution is generally disordered, which not only affects the exercise effect, but also harms your health.

The harm of immediate exercise after meals

Matters needing attention
1, just after eating, the food in the stomach will vibrate up and down and left and right with exercise, which will cause mechanical stimulation to the stomach, lead to stomach cramps, vomiting and other adverse reactions, so it is this reason that you can't exercise immediately after eating.
2, exercise to lose weight requires a lot of blood to transfer oxygen, and after eating, the human body will concentrate a lot of blood in the stomach and digest the food just eaten as soon as possible. This will make the blood that should be concentrated in the gastrointestinal tract disperse to all parts of the body, resulting in insufficient blood supply to the gastrointestinal tract, reduced digestive function, disordered digestion and absorption, and seriously affecting health.
