Ice cream sundae / falooda

One serving of Ice cream sundae / falooda — 1 glass (300 ml) — comes to 380 kcal, 8 g protein, 60 g carbs and 12 g fat. Scaled to 100 g it works out to 127 kcal and 2.7 g protein, which makes it not a meaningful protein source on its own for a fast food item. That single serving is about 25.3% of a 1,500 kcal day and 19% of a 2,000 kcal day, so it's more of a filler than a target-hitter on protein without much extra planning.

Walking off Ice cream sundae / falooda takes roughly 9,500 steps, using the rough approximation of 0.04 kcal burned per step (a population-average estimate for a moderate walking pace, not a personalised number).

It's a packaged/processed item, worth checking the label against this estimate.
