Sweet lassi (dhaba style)

One serving of Sweet lassi (dhaba style) — 1 glass (250 ml) — comes to 193 kcal, 7 g protein, 30 g carbs and 5 g fat. Scaled to 100 g it works out to 77 kcal and 2.8 g protein, which makes it not a meaningful protein source on its own for a dairy item. That single serving is about 12.9% of a 1,500 kcal day and 9.7% 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 Sweet lassi (dhaba style) takes roughly 4,825 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). At ₹40 a serving it costs about ₹114.3 for every 20 g of protein it delivers, which is a mid-to-high price for protein compared with dal, eggs or soya chunks. It fits nearly every Indian diet type, including vegetarian, Jain, eggetarian. It works at breakfast, lunch and the evening snack slot.

If you want variety without changing the macros much, the closest swaps in the dairy category are Butter, Chaas / buttermilk (salted, thin), Processed cheese slice, Curd / dahi (toned milk) — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
