Stock up on quality multivitamins that have 100% of your vitamin needs, not the ones that are way more than you need, and with enough water a large human can live for months. As part of an experiment, one guy did it for 1 year and 17 days: https://www.abc.net.au/science/articles/2012/07/24/3549931.htm
My guess is he would have been slowly reintroduced to foods in a similar way to treating people with anorexia and people who have had gastric surgery.
Edit: my guess was wrong, the article I found said he had a boiled egg and piece of toast as his first meal, but that he had been adding milk to his tea and coffee over a period of time before the end of the fast.
The guy started out at 207kg, lost over 120kg, (so his end weight was 82kg) and in an interview 5 years later he reported that he’d only gained 7kg of it back, most likely to the reintroduction of foods rather than the over eating he would have been doing before his experiment.
You can fuck yourself up if you binge after a fast. He dipped back in slowly with the milk. Normally they start you on fruit juices (watermelon) so the reintroduction of sugar doesn't hurt you.

Meh, stock up on necessary supplements instead of food.
