From which lifestyle practice do Mormons refrain as part of their faith?

Mormons, formally known as members of The Church of Jesus Christ of Latter-day Saints, adhere to a health code known as the Word of Wisdom, which explicitly advises against the consumption of alcohol and tobacco. This practice reflects their belief in maintaining a healthy body and spirit, aligning with their values of physical and spiritual well-being. Abstaining from smoking and drinking is a significant part of their lifestyle, as it enhances not only personal health but also their ability to live a life that is in harmony with their religious teachings.

The other options represent lifestyle choices that, while they may be associated with various groups or faiths, are not stipulated by the teachings of the Mormon faith. For instance, while some Mormons might engage in vegetarian diets or fasting, these are not universal requirements or prohibitions within their religious framework. Frequent exercise regimes, likewise, are not specified as a practice to be avoided; rather, they are generally encouraged for good health but are not inherently tied to religious observance.
