Nasi Lemuni is one of those Kelantanese and Terengganu things most Malaysians outside the east coast have never tried, which is a shame because it is genuinely good. A full set comes in at around 580 calories, which is honestly not bad for a plate of rice with protein. The herbal rice cooked with daun lemuni and light santan is the main calorie driver at 350 kcal, with the sambal adding another 90. The hard boiled egg and ikan bilis bring the rest. One honest caveat though: these figures are a rough estimate, bro. Nasi Lemuni is niche enough that there is basically no formal nutritional data on it, so treat these as a ballpark rather than a lab result.
What actually changes the maths here is the sambal and what protein you add. A basic set with ulam, egg, and ikan bilis sits at 580 calories, which is manageable. But the moment you upgrade to ayam goreng berempah, that jumps to roughly 750 calories. Sambal portion matters too as 2 tablespoons is already 90 calories, and some stalls pour it on heavy. The ulam is basically free at 15 calories for 60g, so eat as much of that as you want. If you want to keep this under 500, skip the ikan bilis, go easy on sambal, and stick to the egg as your only protein. The herbal rice itself is the part worth eating lah, so do not cut that.
