It is generally not suitable for eating within 30 minutes after fitness, including oats. The reason is that although the body consumes a lot of water, fat, trace elements and energy after exercise and needs to be supplemented urgently, the digestive function of the body is also inhibited after exercise, and eating at this time is not good for the body. General fitness is more important to lose weight and shape. Eating immediately after exercise will make your previous exercise useless, and even get fat if you eat too much. It is advisable to eat one hour after fitness. At this time, the digestive function of the body is basically restored, and the fat consumed in the cells is almost the same, which has no effect on weight loss and body shaping. Oats can be eaten with milk after fitness, which is better for body shaping! Because milk is rich in high protein, it tastes good with oats and can promote muscle growth.
