Caloric Intake Formula

https://www.muscleandstrength.com/tools/bmr-and-daily-calorie-calculator.html 
 = Your Daily Calorie Requirements Are: 2489 Calories Per Day

@ 155lb body mass
1. Set protein intake at 1g/lb of lean body mass = 155g (21 g per 100g chicken breast / 1 large Egg = 3.6g)
2. This individual is moderately insulin sensitive so 
   we’ll set his carbohydrate intake at 
   1.5g/lb of lean body mass: = 232.5g (approx 6-7 cups rice)

3. Since carbohydrates and proteins contain 4 calories per gram, 
   then we have (155+232.5) x 4: 1550 calories from proteins and carbohydrates

4. Therefore, this individual’s fat intake will come from 
   the leftover calories to reach 2489: 2489-1550=939 calories
   
     939/9 (fat calorie) calories per g of fat=~104g of fat per day
