Bananas have a lot of carbohydrates: about 30 g for one medium banana. A 2008 study showed that carbohydrate ingestion 15 minutes before running enhanced endurance and increased time to exhaustion by nearly 13%.

Despite all beneficial properties, an excess of bananas harms the body. Bananas are not high-calorie fruit, but consuming them too much will cause unwanted weight gain. As mentioned above, the high content of carbohydrates in bananas can complicate blood sugar control for people with diabets.

Bananas, on their own, do not cause weight loss, but they have some properties that can help to reduce bloating, control appetite, and lose extra kilograms and centimeters around the waist faster. One research found that the daily intake of 24 grams of banana starch for four weeks caused weight loss of 1.2 kg while also improving insulin sensitivity.

On the other hand, eating fruit on a regular basis leads to weight loss by increasing fullness and reducing appetite. So, if you want to slim down, avoid sweets and opt for bananas.

The best time for eating bananas is in the morning. In the mornings, our body is more sensitive to insulin. Whenever we eat something, the body produces insulin, a hormone that accelerates the oxidation of sugar in the cells and helps to process food. Bananas, in turn, are a lot of natural sugar absorbed by the body much better, but anyway, it is sugar. Therefore, to help your body process the banana's carbohydrates easier and quickly, consume them until 10 a.m.

Start your day with bananas. Add them to the oatmeal. Firstly, like bananas, oatmeal is bland and easy to eat while providing the calories, vitamins, and minerals you need. Secondly, this mixture causes a feeling of fullness for a long time and supports the work of the digestive system. Finally, bananas are sweet enough to give sweetness to a bowl of oatmeal, replacing the additional harmful sugar.

Besides breakfast, consume bananas after workouts if you want to drop a few kilos. Exhausting training burns calories, and you start feeling hungry. To fix the result in the gym,  refuse cookies, energetic high-calorie bars, salty snacks, and fast food in favor of exotic fruit. One banana can increase your energy because it is rich in carbohydrates.

Avoid bananas at night. As coffee or green tea, bananas affect our bodies like an energy booster. When it's bedtime, and your body needs to relax and slow down all processes of the organism, banana compounds can lead to an energy crash and prevent you from falling asleep.

Also, it's best if you don't eat bananas after lunch. In the late morning, when you have just dined, your body processes the food, which is why the insulin level in your blood becomes higher. Bananas, in turn, increase the amount of sugar in the blood, which will dramatically drop. As a result, you will feel tired, exhausted, and hungry.

There are no strict restrictions on how many bananas per day you can afford. The appropriate number of bananas varies from person to person. However, excessive passion for exotic fruits can cause headaches, elevated sugar levels, drowsiness, and weight gain.

According to the USDA guidelines, you should consume two cups of fruits per day, which amounts to two big bananas. Up to 2 bananas are the average daily dose for adults, which provides all nutritional properties to your body and, at the same time, doesn't prevent weight loss.
