Is it better to work out on an empty stomach or after a meal? Why?

Fitness is a way of exercising, and if you exercise, you will have the body's energy expenditure, and there will be the body's nutrient consumption. The purpose and starting point of fitness is to obtain good health and beauty.

The choice of exercise time is not on an empty stomach, or after meals. It's about your body's blood sugar, which is the middle choice between whether you're hungry, or ready to feel hungry, and having eaten a full meal. <>

Fasting means that your blood sugar is starting to drop and your energy is starting to be insufficient, such as after eating at noon, go to exercise at 5 or 6 o'clock after work. The high-intensity exercise will make your blood sugar run out when you are about to run out, and the liver sugar consumption is not enough, forcing the body to enter a compensatory state.

If the exercise is mainly anaerobic exercise, it will definitely break down body proteins. If it is mainly aerobic exercise, it is mainly to break down fat, and at the same time, body protein will also be destroyed.

And the body provides energy under sugar-free digestion, which will produce a large number of intermediate products, lactic acid, pyruvate, purine, pyrimidine, uric acid, etc.

Therefore, it is not recommended to go to fitness and exercise on an empty stomach or in a state of low blood sugar. The good time is at 3 o'clock, 4 o'clock, 5 o'clock, and dinner is eaten after exercising and fitness. <>

Fitness exercise after meals is also not good and is not recommended. Just after eating, the blood flow of the whole body is concentrated to the stomach and intestines, which helps to digest food and absorb nutrients.

At this time, when you go to exercise and fitness, the blood is forced to divert, and the forced concentration is concentrated in the limbs, hands and feet, and the blood flow to the stomach and intestines is reduced, which seriously affects digestion. It can cause indigestion, malabsorption of food nutrients, and gastrointestinal diseases.

It is best to rest for an hour after eating, and then go to exercise and fitness. <>

Sports and fitness are conditional, the so-called fitness exercise, the physiological performance of the body is the consumption of energy and nutrients, if the energy and nutrition can not keep up, the body's consumption will become loss.

Fitness exercises that lack protein deplete the body's muscle tissue. Lack of calcium and magnesium for fitness exercise, the body is prone to osteoporosis and muscle stiffness. Exercise without vitamin B will definitely produce a lot of acidic substances and the body's metabolism will slow down.

Exercise lacking vitamin C makes the body's ligaments and muscles brittle.

It is better to work out after meals, because it can make the body healthier and help digestion, so you can choose to work out after meals.

It's good to work out after meals, but don't eat too much, it's not okay, eat less meals, and then work out half an hour after meals.

It is good to exercise after meals, but it should be noted that you can only exercise after 30-60 minutes after meals, and if you exercise on an empty stomach, it will cause insufficient blood sugar and dizziness.

Fitness, fasting exercises, exercise, muscle gain, fat loss.

It is better to exercise half an hour after meals, and exercise before meals at night is fasting exercise, exercise requires appropriate energy, the body's usual energy mainly depends on the sugars ingested in the diet, but when exercising on an empty stomach, the main energy depends on fat.

When people exercise on an empty stomach, the free fatty acids in the blood will increase significantly, and if the fatty acid muscle activity is excessive, there will be "poisons" that damage the myocardium, causing arrhythmia, and even leading to sudden death. Therefore, drinking a glass of milk or eating some pastries before exercising on an empty stomach can reduce the risk of hypoglycemia.

On the contrary, exercising half an hour after a meal can effectively avoid the harm of fasting exercise, and it is more appropriate not to exercise immediately after eating, and it is better to exercise half an hour after eating.

It depends on the fitness person's own situation, whether you are working out before or after meals, the one that suits you is the best. If you have dinner at 6 o'clock, exercise from 8 o'clock to 9 o'clock is acceptable, and it is OK to go home and relax and go to bed around 11 o'clock.

Evening before and after dinner fitness:

1. Try to work out as early as possible at night, not late, it is best to eat dinner about 1 2 hours before exercising, replenish enough energy, and supplement protein food or whey protein powder after fitness.

2. If you get off work late and want to go straight to the gym, it is best to eat food prepared in advance, such as a bento meal, before getting off work. If you don't have a bento meal, you can have a simple dinner, such as instant oatmeal, bananas, milkshakes, etc. Supplement with protein after your workout.

3. If you get off work early and want to go to the gym directly, you can add a meal around 3 or 4 o'clock in the afternoon, and then add protein + a simple dinner after the workout.

Eating a full dinner and then exercising can indeed replenish good energy and get good training efficiency. But if it's eight o'clock when you're full, exercising as soon as you're full is bad for your health and training efficiency. It's not ideal to start exercising at 10 o'clock two hours after the stomach has digested!

After exercising, 11-12 o'clock is still in a state of excitement"Interfere with sleep", the fitness effect will be affected.
