you don't have to eat anything that makes you feel bad. if you do want to try adding in carbs, and it sounds like you were curious to do so, 400 grams of rice is nearly a pound of rice! that's probably overdoing it for one meal, particularly only adding half a can of tuna. after a work out, it's fine to go heavy and carbs and protein, but that's actually quite light on protein, and the macro ratio is kind of... weird.
as for feeling depressed, fatigued and tired after eating that pound of rice, well, that's not really a normal reaction - the depression at least. but if that's what happened, definitely don't do it like that again.
"dean ornish and dr. davis think the palmitic acid our bodies use for fuel while we sleep is poison if we eat it. zero-carbers like charles washington think the oldest fuel in our evolutionary history – glucose - used by organisms a billion years ago and without which the brains of modern mammals cannot survive for more than a few minutes – is an unnatural toxin if you eat it. both views ignore basic facts of medical physiology and defy evolutionary history." - kurt harris
