🔹 Formula Used

1. Protein (g):

Protein (g)=Body Weight (lbs)×Protein Ratio (g/lb)\text{Protein (g)} = \text{Body Weight (lbs)} \times \text{Protein Ratio (g/lb)}Protein (g)=Body Weight (lbs)×Protein Ratio (g/lb)

2. Fat (g):

\text{Fat Calories} = \text{Total Calories} \times \frac{\text{Fat %}}{100}, \quad \text{Fat (g)} = \frac{\text{Fat Calories}}{9}

3. Carbs (g):

Remaining Calories=Total Calories−(Protein Calories+Fat Calories)\text{Remaining Calories} = \text{Total Calories} – (\text{Protein Calories} + \text{Fat Calories})Remaining Calories=Total Calories−(Protein Calories+Fat Calories) \text{Carbs (g)} = \frac{\text{Remaining Calories} \times \text{Carb %}}{4}

🔹 Example Calculation

• Body Weight: 160 lbs
• Daily Calories: 1800 kcal
• Protein: 1 g/lb → 160 g
• Fat: 25% → 450 kcal → 50 g
• Carbs: 100% of remaining → 1190 kcal → 297.5 g

Result:

• Protein: 160 g
• Fat: 50 g
• Carbs: 297.5 g
