Earlier quoted context omitted.
This. I eat at my desk because I want that break time to do something else that actually matters to me and furthers my own personal goals
In some places this can develop into the expectation that everyone eats while working at their desk every day. You're not shifting the free time, you're just losing it. Then anyone who announces "okay, off to a cafe, see you in an hour" is seen as slacking.
Nobody will actually enforce it, but employee will know that eating at a normal pace and taking a breather is an option.
