Carb Counting Calculator
Net carbs = total carbs - fiber - (sugar alcohols × 0.5).
Carb Counting at a glance
Rather than a generic budget, the Carb Counting below personalizes it - your own carb total, fiber and sugar alcohols combine into net carbs, and your insulin-to-carb ratio turns the meal total into a dose. Net carbs are the design rule here: the calculator subtracts fiber and sugar alcohols from the total you entered, then applies your insulin-to-carb ratio, with every step shown in the code.
Net carbs = total carbs - fiber - (sugar alcohols × 0.5).
About Carb Counting Calculator
Net carbs = total carbs - fiber - (sugar alcohols × 0.5).
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.
