Consumption of a controlled and healthy diet is advantageous for the human body as it reduces the risk of heart diseases, diabetes and obesity.
The human body starts to respond to dietary changes as soon as it adapts to these changes. Dieting improves the over-all well-being of a person and protects the body from the risk of several diseases. A healthy diet controls the sugar level in the blood. Intake of carbohydrates increases the sugar level in the blood, however, this rise depends on the glycemic index in the food. Glycemic index determines the effect of food on blood sugar levels. When this index is high in the food, it is broken down quickly, followed by an increase in blood sugar, eventually leading to higher risk of diabetes, heart diseases and obesity. Thus, a healthy diet excludes intake of foods such as candy, soft drinks and white bread with high glycemic index to lower these risks. A steady blood sugar level is beneficial in in terms of higher energy and improved concentration.
Also, reducing the amount of coffee in daily routine can reduce the stress level hormone, cortisol. A person having high level of cortisol finds it difficult to manage pressure. Caffeine damages the immune system and also increases the adverse effects of the hormone. A healthy diet also restricts the intake of calories but if the restriction is severe it impedes weight loss and ineffectively burns fat and prevents the body from being efficient. Therefore, while maintaining a healthy diet, it is important to maintain a healthy metabolic rate which requires both exercise and a sensible diet. Since an unhealthy metabolic drop can lead to slower burning of fat, it is generally recommended to never restrict intake of calorie to less than 1,000 to 1,200 calories per day.
