Nutrition & alcohol calculators

Macronutrients and drinks are where nutrition gets practical: how much protein, how much fat, how much carbohydrate, and what a glass of wine or a pint actually costs in energy. These calculators turn a target into grams per day, spread protein across meals, estimate the alcohol in a drink, and show how caffeine clears from the body through the day. They give general guidance, not a diet plan, and they do not account for medical conditions or medication.
