Sup tulang sits at around 350 calories per bowl for the clear version, and honestly that's not bad at all for how satisfying it is. You're getting 26g of protein, which is solid, but the fat is also 26g and that's mostly coming from the bone marrow. That 22g of marrow packs 170 calories on its own, bro. It's basically concentrated fat in a hollow bone, which is exactly why it tastes so good when you suck it out. The meat off the bone adds another 140 cal, the broth is a light 50 cal, and the tendon and cartilage contribute 30 cal. Worth noting: these are ballpark estimates because detailed nutritional data for sup tulang specifically is quite thin, so treat the 350 cal figure as a reasonable guide rather than a precise count.
The version that actually messes with your tracking is sup tulang merah, which runs around 480 calories per bowl. That extra 130 calories comes from the red rempah sauce made with ghee, tomato puree, chilli paste, and sugar. Same bones, completely different calorie story. So if you're at a gerai and they ask which one you want, the clear broth saves you a meaningful chunk. Practical tips: skip soaking your bread in the broth (that soaked-in roti adds calories fast), ask for less sauce on the merah version, and don't go back for a second helping of the marrow bones if you're watching intake. The soup itself is actually your friend here. It fills you up, it's warm, and the protein from the meat is real.
