The reduction in calories deprives these people of a healthy diet. It deprives the body of the essential nutrients necessary for health. Restricting calories that fall well below the required amounts can be extremely harmful to the body. Any person considering dieting in such a way should always be informed about the harmful effects of dieting. Firstly, when the body does not receive the proper nutrients it needs to go about daily living; it results in lack of energy. The body needs a certain amount of calories to function. Depriving the body of these calories results in severe loss of energy. The body is unable to convert foods to energy when a person reduces his or her calorie intake. Sugar levels will decrease exponentially and this leads to fatigue.
When one is tired all the time, one tends to become irritable. Fatigue and irritability go hand in hand with extreme dieting. Some people who go on these diets crave for foods and cheat themselves by consuming all types of unhealthy foods which can be even more harmful for their bodies. The metabolism, naturally, slows down with reduced calorie intake. This occurs because the body tries to conserve energy as much as possible to compensate for the inadequacy. This does not do any good. All it does is maintain weight and stall weight loss. It also leads to loss of muscle. Extreme dieting causes the body to conserve fat deposits and increase muscle wasting. The wasting of muscle is not the way to lose weight. One must lose fat instead. Extreme dieting, therefore, is not the right way to go if a person wishes to lose a few kilos.
Extreme dieting also affects food digestion. For example, the body requires fiber and water from a number of foods for proper digestion. With extreme dieting, a person can prevent these foods from entering the body and this hinders the body’s ability to digest. It slows down digestion, lead to constipation and bloating. Reduced calories affect the function of the gallbladder. Therefore, extreme dieting can also cause the formation of gallstones. A healthy diet provides the body with the nutrients it needs to grow and stay healthy. The body suffers drastically with extreme dieting.
When the body is deprived of its nutrients it starts to show in a person’s outer appearance too. Because of the lack of nutrients hair tends to look slack and unhealthy. The skin loses its healthy glow and starts to take on a wrinkly appearance. People who diet a lot tend to wrinkle faster than others. The appearance of stretch marks is also not uncommon when the skin starts to lose elasticity. There are so many harmful effects of dieting. Yet, many people tend to do so without a thought to the repercussions. This is because they are thinking of the present and not the future. The harmful effects of dieting will only become apparent later. By then, sometimes, it is too late.
