Alcohol Calorie & BAC Calculator
Calories, alcohol grams, and estimated BAC from drinks.
Alcohol Calorie & BAC at a glance
Standard units are the design rule here: the calculator counts your drinks in standard units, adds 7 calories per gram of alcohol, and applies the Widmark elimination model shown in the code - no hidden adjustments. Rather than a single average, the Alcohol Calorie & BAC below personalizes it - your drink count, body weight and sex feed the same unit math and Widmark formula used in forensic estimates, and every gram of alcohol carries its full 7 calories.
Calories, alcohol grams, and estimated BAC from drinks. The page is written for people who log their drinks: the calorie figure slots into the same food diary Macrition uses for calories and macros, so a night out stays visible next to everything else you record.
About Alcohol Calorie & BAC Calculator
Calories, alcohol grams, and estimated BAC from drinks.
This diet calculator helps you assess, plan, or optimize a specific dietary pattern. Diet quality is one of the strongest modifiable risk factors for chronic disease, research consistently shows that what you eat matters more than precise calorie counting for long-term health outcomes.
Evidence base
This calculator is based on validated dietary assessment tools and evidence from large cohort studies (Nurses' Health Study, EPIC, PREDIMED) and randomized controlled trials. Each dietary pattern has a unique evidence base for specific health outcomes.
Practical application
Use the result to identify areas for dietary improvement. Focus on one or two changes at a time rather than overhauling your entire diet. Sustainable changes produce better long-term results than dramatic overhauls that last only a few weeks.
