How do you say "I can eat whatever I want to eat" in Chinese?

I think it would be more accurate to say:

我随便吃 (wo3 sui2 bian4 chi1)

Loosely translated, it means "I'll eat what I want." This could be used at a table when someone is trying to serve you all the time (which happens often in China). When you say it, it can be received as "I'll eat what I want," or "Let's not stand on ceremony . . . I'll serve myself and eat what I want."

Good luck!

wo xiang chi shen me jiu chi shen me (3-3-1-2-0-4-1-2-0)

simply say: sui bian

What kind of food do Greeks eat?

Sue husband and wife

Will a spiny eel eat pellet food?

随便，吃什么都行

The proper way to say"eat whatever desired" "想吃就吃"

pronounced as "xiang chi jiu chi"

So, "whatever I want to eat, I eat" is 我想吃就吃 (wo xiang chi jiu chi)

Just change the first character for you, he, she, they:
you (singular)- 你想吃就吃 (ni xiang chi jiu chi)
he/she/it - 他/她/牠想吃就吃 (ta xiang chi jiu chi)
we - 我們想吃就吃 (wo men xiang chi jiu chi)
you (plural) - 你們想吃就吃 (ni men xiang chi jiu chi)
them - 他們想吃就吃 (ta men xiang chi jiu chi)

mei you wen ti. - no problems

chi shen me duo ke yi - eat anything is OK

i think i can eat whatever i want to eat is 我可以吃任何我想要吃
and whatever i want to eat, i eat is 无论我想要吃，我吃 or something like that
