Before starting exercise, muscles need some energy to start working, and they need to take carbohydrates to get instant energy, and only carbohydrates can do this. At the same time, muscles and blood cells need to be supplemented with protein to provide oxygen and other nutrients. However, although the body needs energy storage, it does not need fat. Fat is difficult to digest, and it takes a long time to convert into energy, which also brings a burden to the stomach. Fiber digestion is also slow, so the diet before exercise should avoid high fiber.

Pay attention to five points before exercise: 1, low fat content; 2. Appropriate amount of carbohydrates and protein; 3. Low fiber content; 4, to add enough water; 5. Try not to try new foods and choose foods that are more accustomed to the body and stomach.

In order to avoid eating something you shouldn't eat before exercise, I will introduce some nutritious recipes suitable for eating before exercise.

Banana: This thing is a natural energy bar. Bananas are rich in digestible carbohydrates and potassium, which helps to maintain muscle and nerve functions. Potassium can't stay in the body for a long time, so the best way is to add some before exercise, so as to ensure that you always maintain a high level of potassium during exercise. Nutritionists suggest that we eat a banana and drink half a cup of yogurt 30 minutes before starting fitness, so that we can basically meet the trumpet required for exercise.

Oats: Oats are rich in fiber, which can help the decomposition of carbohydrates and prevent blood vessels from clogging. At the same time, its fiber content will not be too high, which will not make you fart embarrassed during exercise. Necessary fiber can keep your body alive during exercise. Oats also contain a lot of vitamin B, which can convert carbohydrates into energy. Therefore, it is also a good choice to have a cup of cereal 30 minutes before exercise.

Note: If your diet does not include the above points, there are several things you must remember-first, don't eat foods with high fat content, because fat will stay in your stomach for a long time, so you will always feel full and weak during exercise. Second, although a moderate amount of carbohydrates is necessary, don't think about taking it by eating sugar, which will make your blood sugar rise sharply during exercise. Finally, don't eat too much. These are snacks, not meals. Eating too much and not digesting it will make you want to throw up during exercise.
