Mild exercise is most reasonable one hour after a meal, moderate exercise should be scheduled two hours after a meal, and high-intensity exercise can be performed three hours after a main meal.
Based on this, we can deduce several optimal exercise time slots:
Morning slot: 3 hours after breakfast until before lunch
Afternoon slot: 3 hours after lunch until before dinner
Evening slot: 3 hours after dinner until bedtime
Why is it not advisable to exercise immediately after a meal?
1. After a meal, insulin secretion increases, which can inhibit fat breakdown, restricting the source of energy. Due to less fat breakdown, it is also not suitable for weight-loss exercises during this time period.
2. Stomach stimulation: Exercising after a full meal can mechanically stimulate the intestines, causing the contents to move back and forth and up and down, potentially leading to symptoms like vomiting and stomach spasms.
3. Impact on weight-loss exercise effectiveness: After eating, the body’s parasympathetic nervous system is easily inhibited, so if the body wants to exercise at this time, the exercise effectiveness will be compromised.
4. Disruption of blood flow distribution: After a full meal, the digestive organs require a large amount of blood for digestion and absorption. When the entire body muscles are in motion, they also require a significant amount of blood supply, causing a competition for blood with the digestive organs, leading to disrupted digestion and absorption functions, which not only affects exercise effectiveness but also harms the body.
