A clear protein-to-calorie ratio shows how many grams of protein you get per 100 calories, so you can choose foods that match your goal.

A typical scoop of whey-based protein powder lands around 100–140 calories, shaped by protein grams plus any added carbs, fats, and flavor mixes.

A standard 30 g scoop usually lands around 110–140 calories, but label math can swing it up or down fast.

One gram of protein delivers around 4 calories of usable energy on nutrition labels, with small swings based on food type and digestion.

A simple macro chart pairs calorie totals with protein, carbohydrate, and fat grams so you can portion food with clear numbers.

A large whole egg lands near 70–80 calories with around 6 grams of protein.

A large fried egg lands near 90 calories and 6 grams of protein, and the cooking fat you use can add as much as the egg itself.

Fat provides 9 calories per gram, while carbohydrates and protein provide 4 calories per gram.

Fat packs 9 calories per gram, while protein and carbs each bring 4, which is why portions can rise faster than they look.

Protein has 4 calories per gram, so multiplying protein grams by 4 gives the calories coming from protein.
