If you only rely on bananas to lose weight, you can't. Because eating bananas on an empty stomach is unhealthy. It is suggested that bananas, oats and yogurt should be combined to lose weight, which is not only healthy, but also more full. You can add oatmeal and yogurt in the morning, depending on your personal situation. Eat normally at noon, add yogurt and bananas at night, or it can be the same as in the morning. If you persist in this way for one month, you can lose 10-20 kg.
