Gym and Ice cream

Nowadays, most of the obese people believe that exercising is the best to lose weight. However, some of them are not determined enough to stop unbalanced diet. They do exercise, but after that, they consume more. This happens very often. Some of my plump friends describe the reason like this: after exercise, they become more hungry and eat more.
The cartoon above- "They opened an ice cream shop by the gym."- shows the problem facing by obese people. In fact, exercising requires a lot of energy. The concentration of glucose in their blood drops below average. When glucose is in short supply, fats are broken down to provide the energy needed for the exercise. At the same time, people start to feel hungry. Imagine that there is an ice cream shop and you are hungry, what will you do? Ice cream is considered to be a kind of junk food which could raise your weight. As people eat more, the effect of exercise disappear; instead, the fat they consume is more than the one they have used, thus they continue becoming heavier.
It is really important for us to have a balanced diet. Those people who want to lose their weight should try to keep themselves away from junk food.
