Khakhra (plain/methi)

One serving of Khakhra (plain/methi) — 2 khakhras (30 g) — comes to 118 kcal, 3.3 g protein, 18 g carbs and 3.6 g fat. Scaled to 100 g it works out to 393 kcal and 11 g protein, which makes it a moderate protein source for a snack item. That single serving is about 7.9% of a 1,500 kcal day and 5.9% 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 Khakhra (plain/methi) takes roughly 2,950 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 ₹8 a serving it costs about ₹48.5 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's typically eaten at the evening snack slot. It's a common tiffin-box item.

If you want variety without changing the macros much, the closest swaps in the snack category are Cream biscuit (Bourbon/Hide&Seek type), Marie biscuit, Paneer sandwich (home, 50 g paneer), Parle-G biscuits — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
