Eating in itself is not a problem. Rather, it is the addiction to habits and customs related to eating that is the issue. If this has occurred, then we need to break the cycle.
From an Islamic point of view, our bodies are a trust(amanah). As the guardians of our bodies, we have the duty to maintain our health and be in good shape in order to worship Allah. We should fulfil the trust given to us, and this includes ensuring that we keep our bodies safe by observing healthy eating habits.
Islam promotes use to do everything in moderation. It encourages simplicity and frowns upon excessiveness and wastefulness. The predominant idea of eating is to give the body enough nourishment, but not so much that it causes us to neglect our worship of Allah. It does not mean that we are to eliminate all delicious flavours from our food and to just serve bone and gristle – it simply means to keep things under control without transgressing any limits or abusing the bounties that Allah has bestowed on us. Mostly, Islam is about purity of the body and soul, and that purity also covers the purity of what we feed ourselves.
