French fries, medium

One serving of French fries, medium — 1 medium (115 g) — comes to 319 kcal, 4 g protein, 42 g carbs and 15 g fat. Scaled to 100 g it works out to 277 kcal and 3.5 g protein, which makes it not a meaningful protein source on its own for a fast food item. That single serving is about 21.3% of a 1,500 kcal day and 16% 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 French fries, medium takes roughly 7,975 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 ₹110 a serving it costs about ₹550 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, vegan, eggetarian. It's typically eaten at the evening snack slot. It's a packaged/processed item, worth checking the label against this estimate.

If you want variety without changing the macros much, the closest swaps in the fast food category are Veg frankie (roti wrap), McAloo Tikki burger, Veg spring roll, Veg burger (local stall/canteen) — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
