It is also been stated that the extra fat which covers over the tissues in the body is a place were various types of microbes can form and grow - just like a garbage can which is full and if kept in a place for a long time could lead to sicknesses and the spreading of various diseases. Some of the things which can protect us from such diseases is to burn off all of our excess body fat - and one of the ways that the fat can be burnt off is through fasting.
All people can understand this fact since everyone can discern that when there is excess food in one's body which is not absorbed into itself, then the body stores this excess, and in the end, the job of the heart then increases. In summary we state that when a person becomes heavier, it has a negative effect on all parts of his body and thus the heart and other organs also get sick faster, and naturally the life of the person is cut short.
Therefore, if a person is sincerely trying to attain goodness for one's self, he must abstain from eating too much food and one must habituate himself to eating less, especially those people who do not exercise much.
A doctor once said, “For over twenty years I have been trying to cure sick people and my answer to all of the experiences (over these years) that I have seen can be summed up in two phrases: 'moderation in food' and 'exercise.'” B) The Spiritual Aspect: The tradition we started with points to three very important spiritual aspects that a person who eats too much will face: The first is that a person who eats too much will develop spiritual hardness of his heart.
The second point is that eating too much will lead a person to becoming lazy and lethargic in his worship. When a person eats heavy food, he is not able to easily perform his Salatul Fajr and when he does wake up for the Salat, he resembles a person who is giddy or drunk. However, when a person eats light and simple food, then when the time of the Adhan comes, or even before the time of the prayer, he wakes up and is full of joy and energy.
He would be in a mental condition to study or to perform the worship of Allah (SwT). The third point is that a person who eats too much will have his ears sealed to listening to and taking heed of advice and good council. When a person is fasting, we see that his heart has pity and sympathy for others in it and his level of spirituality increases.
