I'm begining to design a meal plan for bulking and gaining muscle mass, but im not sure how many calories i need per day. I know theres an equation for this but i can't find it. Anyways I weight 155 lbs. and I am about 5 ft 9 in.
Here's one formula..
Harris-Benedict formula (BMR based on total body weight)
Men:
66 + (13.7 * (weight in pounds/2.2)) + (5* (height in inches * 2.54)) - (6.8 * age in years) = BMR
BMR * AL = Maintenace
Women:
655 + (9.6 * (weight/2.2)) + (1.8 * (height * 2.54)) - (4.7 * age) = BMR
BMR * AL = Maintenace
Basal Metabolic Rate (BMR)
BMR is the sum total of all the energy used for these basic bodily functions(1), not including physical activity.
(1)Breathing, digestion, circulation, temperature regulation, cell construction, and every other metabolic process in your body burns calories.
Activity Level (AL):
Sedentary (1.2) - little or no exercise, desk job
Lightly Active (1.375)- light exercise/sports 1-3 days/wk
Mod. Active (1.55) - moderate exercise/sports 3-5 days/wk
Very Active (1.725)- hard exercise/sports 6-7 days/wk
Extr. Active (1.9) - hard daily exercise/sports & physical job or 2 X day training, marathon, football camp, contest, etc.
