Nutrition is the most important part of living healthy and if you hope to meet your fitness goals, counting calories is vital. The amount of calories you consumer per day depends entirely on the how active you are and what your fitness goals are, but here’s a great equation to help you get started.
Body weight x 10 = Resting Metabolic Rate (RMR)
RMR x 20% = Daily calories burned outside of exercise
RMR + Daily Calories Burned + 600 = Energy Amount
Now that you have your Energy Amount number, compare it to the list below to figure out which level you’re in and how many calories you should be consuming daily. Keep in mind that this equation was created with P90X in mind so it’s taking into account an extreme daily workout of about an hour per day and 6 days per week.
Level 1
- * 1800-2399 Energy Amount
- * 1800 calories per day
Level 2
- * 2400-2999 Energy Amount
- * 2400 calories per day
Level 3
- * 3000+ Energy Amount
- * 3000+ calories per day
I just referenced this post on my blog that journals my experiences with P90X. http://p90x.teddarr.info/p90x/post/2010/09/20/Is-it-necessary-to-stick-to-the-P90X-Nutrition-Plan.aspx Thanks for the research and getting this information online.
