Buffalo milk (raw, local dairy)

One serving of Buffalo milk (raw, local dairy) — 1 cup (240 ml) — comes to 259 kcal, 8.9 g protein, 20.2 g carbs and 15.8 g fat. Scaled to 100 g it works out to 108 kcal and 3.7 g protein, which makes it not a meaningful protein source on its own for a dairy item. That single serving is about 17.3% of a 1,500 kcal day and 13% 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 Buffalo milk (raw, local dairy) takes roughly 6,475 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 ₹17 a serving it costs about ₹38.2 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, the evening snack slot and dinner. It's commonly eaten on fasting days (Navratri/Ekadashi-style).

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.
