Another advice is to abstain from whatever you desire...
Remember the saying of the Prophet Daniel about his fasting: “I ate no pleasant food, no meat or wine came into my mouth” (Dan 10:3)... I say that because many eat a lot of desirable vegetarian food and enjoy it. Therefore, they do not really feel that they are fasting, and then they do not benefit from their fasting, especially if there was a mother or a wife who is expert in cooking vegetarian food and makes it more appetizing than ordinary food.
Therefore, place before yourself two observations during your fast: the first is that you do not ask for specific types of food that you enjoy. The second is that if desirable food is placed before you, do not satisfy your desire and eat from it. Or else take a small amount and leave the rest and control yourself. Or mix the desirable with the undesirable, so that the desirable will not taste that good.
