No matter which meal, do not eat starchy food, such as rice, noodles, sweet potatoes and so on. It is easy to cause insufficient brain energy and affect attention and memory. Eating too little starch can easily affect thinking and mood.
Starch foods include rice, noodles, buns, bread, sweet potatoes, yams, pumpkins, potatoes and so on. They are rich in carbohydrates, which not only provide energy for the body, but also the decomposed glucose is the only energy source for the brain! Nutritionist Song Minghua pointed out that the brain consumes about 500 calories a day, which is equivalent to about 130 grams of carbohydrates.
Therefore, no matter which meal does not eat starchy food, it will reduce the intake of carbohydrates, resulting in insufficient brain energy, affecting attention, memory, thinking and so on. , and even cause emotional instability, irritability.
The lack of carbohydrates in turn consumes glycogen.
Without energy, the brain will use glycogen stored in the liver as energy in an emergency. But nutritionist Song Minghua said that the storage of liver sugar can only last for about two days at most. Once consumed, the liver will use protein to make sugar.
The liver is also short of glycogen, which consumes muscle but does not lose fat.
At this time, if the protein in the body is insufficient, the body will turn to the protein in the muscle and consume muscle tissue. In other words, the body will "sacrifice muscles for the brain." Therefore, if you don't eat starch staple food during weight loss, it is easy to reduce lean tissue, not fat!
