Add sunscreen to the list. My pet peeve!A severe weight-loss diet is typically about 1200 to 1500 calories per day, depending on the person's weight and health, and usually has a minimum of about 30 grams of protein. A diet of 400 calories a day means slowly starving to death, with numerous ill effects in the interim. The drama and tension of "Survivor" depend on game play, challenges, strategy, alliances, etc. I just don't see any reason that the players couldn't get at least an unlimited supply of rice, maybe with some powdered milk and a few cans of tuna. Even a lifeboat or a bomb shelter is stocked with survival biscuits. Or if food needs to be part of the game, maybe there should be a competition every day where the winning team gets a great meal and the loser gets gruel. But watching people starve is not much fun.
