Creatine monohydrate

One serving of Creatine monohydrate — 1 scoop (5 g) — comes to 0 kcal, 0 g protein, 0 g carbs and 0 g fat. Scaled to 100 g it works out to 0 kcal and 0 g protein, which makes it not a meaningful protein source on its own for a supplement item. That single serving is about 0% of a 1,500 kcal day and 0% 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 Creatine monohydrate takes roughly 0 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 and 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 supplement category are Electrolyte / ORS drink, Peanut butter, high-protein (MyFitness/Pintola), Plant protein (pea+rice), 1 scoop, Sattu (roasted chana flour), plain — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
