The harm of not eating staple food

The appropriate dietary energy composition recommended by WHO is: 55%~65% energy from carbohydrates; 20%~30% energy from fat; and 11%~15% energy from protein. During exercise, the body mainly relies on carbohydrates to supply energy, maintain exercise intensity, and provide energy for muscles and brain.

Unlike protein and fat, the body's carbohydrate reserves are very limited. If the body does not get enough carbohydrates during exercise, it will cause muscle fatigue and lack of motivation. Not only that, if the diet lacks staple foods for a long time, it will lead to low blood sugar levels, causing dizziness, palpitations, brain dysfunction and other problems. In severe cases, it can lead to hypoglycemia coma.
