Sugar

One serving of Sugar — 1 tsp (5 g) — comes to 20 kcal, 0 g protein, 5 g carbs and 0 g fat. Scaled to 100 g it works out to 400 kcal and 0 g protein, which makes it not a meaningful protein source on its own for a sweet item. That single serving is about 1.3% of a 1,500 kcal day and 1% 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 Sugar takes roughly 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). Cost data for this item wasn't reliable enough to price per gram of protein, so treat it as a calorie source rather than a protein strategy. It fits nearly every Indian diet type, including vegetarian, Jain, vegan. It works at breakfast, lunch, 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 sweet category are Jaggery (gur), Jalebi, Kaju katli, Modak (steamed, coconut-jaggery) — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
