THE CAUSES AND SOLUTIONS TO OBESITY
According to some new nutrition studies, high and frequent consumption of carbohydrates is proved to be the main cause of obesity which is very common in teenagers and young adults. Surprisingly, by controlling the carbs intake, people can make their own healthy diets to fight obesity.
Scientifically, the human body runs on glucose, which is the main source of energy. Any kinds of food taken into our body, like rice, bread, meat, milk, cheese, and sugar drinks, are broken down into glucose. Then, the amount of glucose is carried in our bloodstream to feed trillions of body cells, under the effects of insulin from the pancreas. When the cells are full, the remaining amount of glucose is stored as glycogen in our muscles and internal organs like the liver. When our body needs energy later, the stored glycogen is released into the bloodstream in the form of glucose and continues feeding the hungry cells.
Obesity happens when the body has too much glycogen stored in the bones and internal organs. The glycogen has to be stored in the form of fat under our skin. The body parts used as "a special fridge" for fat are belly, bottom, thighs, and upper arms. For an average person, the more fat they store, the higher their BMI (Body Mass Index). If their BMI is from 25 to 29, they are overweight. If it’s over 30, they are obese.
To prevent and cure obesity, people have to choose what to eat carefully. Food high in carbs and sugar, like artificially sweetened foods and sugary drinks, cause insulin to rise quickly, which makes the body store fat as soon as the body cells are full. Moreover, those foods are highly digestible, which means the body digests them quickly. As a consequence, the body gets hungry just around one hour later, and then, people must eat again. On the contrary, foods rich in protein and fat, like beef, chicken and dairy products, cause insulin to rise very slowly, and they take longer to be digested, which keeps the body full for a longer time and stores fat slowly.
In conclusion, healthy eating is choosing what to eat smartly, and it starts in the kitchen. Keeping track of your daily diet is essential to get you in shape.
