Eating to Bulk Up is as easy Adding

1) Multiply your weight by your activity level to estimate your daily caloric needs for your current weight.

 2) Before you can increase your calorie intake you have to know what it takes per day to function:

 If you are an active man multiply your weight by 15 but if you are inactive multiply by 13. 

• If you are an active women multiply your weight by 12 but if you are inactive multiply by 10.

Add 500 or 1,000 to your calories needed to maintain current weight. Gain 1 to 2 lbs. per week by increasing your calorie intake by 500 to 1,000 per day. For example, if you require 2,000 calories per day but want to gain 1 lb. per week you must lincrease your daily calorie intake to  2,500.
