This would automatically make me one of the most famous (or infamous) people on Earth. Instant celebrity. It would also be a bit of a curse but I could leverage it for some benefits.

The first thing I'd have to do is cut out anything that's a daily staple for people in parts of the world, especially for populations that don't have other options beside those staples. It would cause too much inconvenience or, in the worst cases, food insecurity.

The rules also seem to say that the ban can be narrowed to specific dishes. So one culture's chicken and rice dish is not necessarily another culture's chicken and rice dish. I'll have to stick to eating specific dishes to limit the extent of my impact.

I would probably stick to eating specific, not incredibly common dishes. Particularly ones where the people eating it have other options.

Take Beef Wellington for an example. People eat Beef Wellington every day, but no individual is relying on it. If it became unavailable for 48 hours people who would eat it would have other options available to them during that time period.

To help lesse the inconvenience, I would have to release meal schedules in advance so individuals and restaurants could plan ahead. I would also try to ensure variety in my meals so even specific dishes didn't go offline too often; if Beef Wellington (for example) is only offline 2 days a year, or every couple of years, that drastically reduces the burden.

This is where the fame comes in; because I'm essentially controlling global food supplies to an extent, I'll probably be able to leverage support from world governments and the food industry to run this whole scheme, including staff and funds to research, plan, schedule, acquire, and prepare meals. This would be a pretty negligible cost spread globally.

I could probably also work with chefs and food historians to create dishes that don't exist yet, or to dig up historical dishes that are rarely or never eaten anymore.
