|morning cardio training|
After an overnight hunger (8-12 hours), your glycogen depot is almost exhausted. Therefore the body uses as more fat.
Food releases insulin. Insulin interferes and interferes with the process of fat burning. The sutra in the blood of insulin is less, hence, and the fat sutras, during exercise, and you can burn more.
Since the morning in the blood less carbohydrates than in the evening. A small amount of glucose also contributes to a more effective fat burning.
If you eat before exercise, then first you will need to use energy from food eaten.
If you exercise in the morning, then the increased metabolism remains for the whole day. If the training takes place in the evening, then the effect of increased metabolism ("Afterburn") after training is almost gone, because the metabolic rate drops sharply when you go to bed.
Morning training gives a sense of satisfaction, and you all day feel a surge of energy. Because the training contributes to the production of the hormone of joy - endorphin.
Morning training contributes to the emergence of a habit: early wake up.
Morning cardio helps to reduce appetite for the whole day.
You are unlikely to "skip" the morning workout (unlike the evening when you are tired after work, and friends call you to the pub).
You can always find time for the morning training, just putting the alarm clock "early".
The main fear of morning cardio training in a hungry state, especially in intensive mode, is the risk of losing muscle. After a night's sleep you are hungry, the level of insulin and glucose in the blood are low. This is the optimal situation for burning fat.
Unfortunately, this is also the optimal environment for muscle catabolism, because at such low levels of insulin and glucose, a lot of catabolic (cleaving muscle) hormone, cortisol, is produced. Therefore, it may seem that morning cardio is a double-edged sword, but there are ways to prevent loss of muscle mass.
Any aerobic exercise has some effect on muscle growth, but until you overdo it, you have nothing to worry about. The fact is that during exercises aerobic muscles are split and used as energy. But you are constantly synthesizing and splitting the muscle tissue to some extent. This is called the "protein cycle", and this is a daily process, from which you can not escape. Your goal is to tip the scales in the direction of anabolism and weakening of catabolism, in such a way that you will increase and support more than you lose for a long time.
