There is no accurate statement on whether it is good to practice in the morning on an empty stomach or with breakfast, and different people can choose the appropriate morning practice according to their own health conditions. Healthy people can do morning exercise on an empty stomach, and patients with low blood sugar and diabetes are recommended to do morning exercise after eating breakfast, but they should not eat too much or do morning exercise immediately after eating breakfast: 1. Healthy people: If the morning exercise group has good physical quality and no symptoms of low blood sugar, they can do morning exercise on an empty stomach. The morning air is fresh and healthy, and the active organism through early morning exercise can strengthen the physical quality and promote metabolism; 2, hypoglycemia and diabetes: people with diabetes or weak constitution are recommended to have morning exercise after eating breakfast. After a night’s rest, all tissues of the body need to replenish energy to complete metabolism, and morning exercise on an empty stomach may accelerate the consumption of sugar, fat and other energy, which may easily lead to hypoglycemia, dizziness, nausea and other uncomfortable symptoms. It is usually recommended to perform morning exercises after breakfast, or you can consume some cookies and candies to replenish energy afterwards to preserve your strength. Blood will be concentrated in the stomach and intestines in large quantities after meals to help digestion. Exercise immediately tends to gather blood in the stomach and intestines and disperse it to all parts of the body, affecting the digestive function; morning exercise immediately after breakfast, undigested food will easily cause stimulation to the stomach and intestines and cause vomiting, so morning exercise activities immediately after breakfast should be avoided. It is recommended that 1-2 hours after breakfast for morning exercise, running, weight-loss exercises, rope skipping and other exercises can be carried out.
