When my casual job cut my hours mid-semester, I made a decision that felt practical at the time: skip lunch to save money. I figured fewer meals meant fewer kilojoules, which meant I might even lose a bit of weight. Neither outcome happened the way I imagined.
What skipping lunch actually produced
By 4pm I was ravenous. I would eat whatever was fast and cheap, usually something fried from the campus outlet or a large bag of chips from the servo. Over eight weeks, I put on weight rather than losing it, and my energy through afternoon classes was noticeably poor.
A 2019 review published in Nutrients found that meal skipping, particularly breakfast and lunch, is associated with higher total daily calorie intake and poorer diet quality in young adults. The body compensates. That is not a moral failing, it is physiology.
What actually worked on a tight budget
I started batch cooking on Sundays. A 2kg bag of rolled oats, a carton of eggs, frozen vegetables, and canned legumes cost under $25 and covered most of my weekday meals. Protein at each meal reduced how urgently hungry I felt by mid-afternoon.
The shift was not dramatic. But it was consistent, and that consistency mattered more than any particular food choice.
