I don't even understand what you're even saying or how you got so much likes saying so many nonsensical misspelled words. 
1. obesity is an issue, also a cause of death to many, so he literally is going through a diet right now, eating mostly low calories stuff + vegetarian food to go back to his healthy body again. The fake food in the game helps him cope with his extreme eating disorder. He also exercise as well before going back to the virtual reality. This can be referenced to the chapter when Kendo was mentioned, and it's clearly working as depicted in the past chapters.

2. He's not relaxing or chilling. He's in the game to have fun and enjoy the food. And this won't put a weight on him and it could make him desires food less since he ate so much already in the game. Since you don't think before you talk while understanding the plot, I'm sure you could re-read the first point and think it over again. Or even what I've said previously and it will make sense.
Also, If you also recall chapter 1 or 2, his dad literally told him to just have fun in the game and to not worry about anything else.

3. You logic makes no sense here. Why would he lose his sanity? Have any streamer or gamer lost their sanity playing games 10-15 hours a day?
