Gluttony can be affixed as losing your priority to the ‘seductive’ power of food and alcohols. When you are uncontrollable to gastronomy desire, everyone tend to enslave themselves to the sin of gluttony.
Controlling this over-excessiveness in drinking and eating habits dated back in centuries. Most religious figures (monks, priests and some pious people) practised simplicity in their daily diet.
• Nabi Muhammad s.a.w. – fasted during the month of Ramadhan for holy spiritual approach to cleanse soul and mind
• St. Catherine of Sienna – starved herself to death. Considered to be holy aneroxist
Most main religion in the world also underlines the importance of eating in moderate level. It is clearly to stay away of killing animals (food supplies), maintaining control over yourself (body and intellectual) and preventing enslaving yourselves into more negative actions (alcoholism)
Easy known ways nowadays are vow of fasting and being vegetarian. Not to say it will completely root out any form of sins or capable of turning you into better person, but, by following certain rigid diet discipline, harm to ourselves could be decreased. Fasting and vegetarianism could be considered holistic approach of committing penance against the sin of gluttony.
