For those of us who have been blessed with an ample supply of food in our pantries and refrigerators and freezers, one option to fasting is to allow your household to simply run out of a food item that you are in the habit of including with your meals, and then "make do" with alternatives on hand, thanking God for the abundance.

Re: "In Lent, Christians should find ample opportunities to pray...."
Using "should" here is problematic because it results in a statement that is "teaching as doctrines the commandments of men" (Matt. 15:9 ESV). People need not feel guilty for not changing their prayer habits for a few weeks.

"One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind" (Romans 14:6).

Yet this loving exhortation applies throughout the year: "In everything by prayer and supplication with thanksgiving let your requests be made known to God" (Phil. 4:6).

So rather than say "should" to encourage a beneficial practice that God does not require, it is more gracious and persuasive to describe the benefits that people have actually experienced and the anticipated blessings that Scripture speaks of: "And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus" (Phil. 4:7).
