Oh you who believe! Fasting is prescribed to you as it was prescribed to those before you, that you many learn piety and righteousness" (Qur'an, al-Baqarah, 2:183)
"...And it is better for you that ye fast, if ye only knew." (Q 2:184)
Focusing on food; to the extent people begin to worry about eating more then actually fasting. This also goes along with spending tons of money on Iftaars even though a person does not need to eat that much food.
This blessed month is a great opportunity for goodness, barakah (blessing), worship and obedience towards Allaah.
Allaah says (interpretation of the meaning):
The month of Ramadan in which was revealed the Qur'aan, a guidance for mankind and clear proofs for the guidance and the criterion (between right and wrong). So whoever of you sights (the crescent on the first night of) the month (of Ramadan i.e. is present at his home), he must observe Sawm (fasts) that month, and whoever is ill or on a journey, the same number [of days which one did not observe Sawm (fasts) must be made up] from other days. Allaah intends for you ease, and He does not want to make things difficult for you. (He wants that you) must complete the same number (of days), and that you must magnify Allaah [i.e. to say Takbeer (Allaahu Akbar: Allaah is the Most Great)] for having guided you so that you may be grateful to Him." [al-Baqarah 2:185]
