1. What is the UK NHS Macro Calculator?

The UK NHS Macro Calculator provides recommended daily macronutrient intake based on the UK National Health Service's balanced nutrition guidelines. It calculates protein, carbohydrates, and fat distribution using established healthy ratios.

2. How Does the Calculator Work?

The calculator uses the UK NHS balanced ratio formula:

\[ Protein = 20\% \times Calories / 4; \quad Carbs = 50\% \times Calories / 4; \quad Fat = 30\% \times Calories / 9 \]

Where:

\( Protein \) — Protein intake in grams per day
\( Carbs \) — Carbohydrate intake in grams per day
\( Fat \) — Fat intake in grams per day
\( Calories \) — Total daily calorie intake

Explanation: The formula distributes calories according to the NHS recommended ratios: 20% from protein, 50% from carbohydrates, and 30% from fat, converting these percentages to grams using the calorie content of each macronutrient.
