Victor Self, a fitness instructor at Flywheel Sports, said that eating within an hour after exercise is a good way to recover after moving and regaining energy.
Susan Besser, a family medicine specialist, also said that delaying eating shortly after exercise will not do you much harm. But if used to miss it, this could potentially cause a decline in your health condition and your sporting ability.
"This effect does not occur directly, it's a cumulative problem, so just skipping one meal will not have a direct impact," he said.
But, if you exercise in the morning in particular and then do not eat for several hours, your body has no energy reserves to use. This means the body will wait for you to refill it with the necessary nutrients to gain strength.
If it becomes a habit, this is what happens if you do not eat after exercise for a long time.
1. Low blood sugar and feel dizzy
Susan Besser says if we exercise in the morning or evening without eating and replenish energy afterwards, "your body will save energy".
The body will take up the glycogen reserves. This glycogen serves to maintain blood sugar stability and will be replenished when we eat. But, this takes time, so that there can be changes in the body's metabolism.
"Because the brain tries to save energy, it is forced to slow down some of its functions," says Susan Besser.
If the brain runs out of sugar, it can not immediately replace it with another source, so its function decreases. Therefore we can feel dizzy or even faint if we do not eat for a while.
2. Muscles will not form and cramp
Susan explains if the body runs out of glycogen, the body will look for other sources of energy. It can be fat or, if there is no fat, it will move to muscle.
If the body is looking for energy reserves in the muscles, it has the potential to remove muscle mass and make muscle weak.
If you are sweating a lot, you may also lose a ton of electrolytes, which can cause muscle cramps. Of course the sport you do will not bring any benefit.
3. Dehydration
If you do not eat or drink, you will become dehydrated after exercise.
"Exercising hard, even under optimal conditions (not in extreme hot weather, for example) causes increased sweating and loss of body fluids," says Susan Besser.
If the lost fluid is not replaced, it may disrupt the electrolyte balance. This is what causes cardiac arrhythmia or palpitations in severe cases, because the body needs electrolytes to keep the heart and muscles functioning properly.
"But this will not happen unless you are chronically malnourished and then force the body to exercise, or if you are taking diuretics that can cause electrolyte imbalances," says Susan Besser.
Clearly, the body needs to be well hydrated. "Just enough water, you do not really need an electrolyte drink unless you do a very long exercise routine in very hot weather or temperatures," he said.
Victor Self also explains that we also need to consume water before exercising. It aims to keep the body hydrated to be ready for sweating.
In essence, if you do a lot of activity and exercise, do not forget to eat and drink to replace the energy that comes out and speed up muscle recovery. With a note, choose healthy food and in the portion is not excessive
