There are very few advantages of any mono-diets. This is a serious blow to the body. The result appears faster, but disappears even more rapidly after the end of the diet, and the negative impact on the body has already occurred. According to reviews, the banana diet is good because it is tasty, easily tolerated, a person eats up, and, therefore, does not feel constant hunger. But these advantages will not outweigh the test that the body undergoes, depriving a significant set of substances and trace elements it needs. It is better to focus on physical activity and proper nutrition, rather than arrange, albeit short-term, but serious stress for the body.
In general, a banana is a fruit that is rarely recommended when it comes to losing weight. Very sweet. After consumption, insulin jumps sharply. Will soon be hungry again. In addition, if you sit on bananas, protein will not enter the body. So, along with fat, your muscles will melt. So, there are no advantages to such a diet.
There are probably no pluses. Of course, eating only bananas with a total daily calorie content of less than you spend during the day, body weight will decrease. But it is worth remembering that the energy value of a banana is mainly due to carbohydrates. Bananas are practically free of proteins and fats. Bananas are also unbalanced in their macro- and micronutrien composition. It contains B vitamins, but very low in vitamins A and E. Adhering to such a diet, your body will not receive the nutrients it needs. In addition to fat mass, you will also lose muscle (due to insufficient intake of protein), a decrease in immunity is possible, and digestive problems may appear. A balanced hypocaloric diet is recommended for weight loss.
