Australian researchers verified that people suffering from obesity are exposed to changes in the structure of the Heart muscle which affect its proper functioning, even if they did not have any heart disease. These changes might lead to later fall in the heart.
These are main factors that cause obesity and consequently cause dangerous disease like heart diseases, diabetes, blood pressure and cancer. But what about the Islamic teachings which was revealed 1400 years ago?
Allah, the Almighty, had specified a golden rule in diet as He said: " and eat and drink but waste not by extravagance, certainly He (All?h) likes not Al-Musrif?n (those who waste by extravagance)" (31:Al A'raf.). The most dangerous thing is extravagance and as long as the person is moderate he will be at the safe side, this is what stated by the western scientists!
Even, the prophet Muhammad, peace be upon him, had given us a remarkable rule in diet which explains Allah's saying (but waste not by extravagance), he peace be upon him says: (the son of Adam had filled a bowl not worse than a belly! Enough for the son of Adam are small mouthfuls to stand him up, but if he was beaten by himself then a third for the food, a third for drink and a third for breath) (the right sequence 2265). The prophet alienated his companions from overeating and said (the son of Adam had not filled a bowl worse than a belly) in order to have in front of their sight while eating that this food might be harmful to them if they fill their bellies with it!
