Then, take into account your regular daily activity. If you take in 1,500 calories, and burn 500 doing P90X, your net after P90X is only 1,000. Again, this is usually in response to previous diet plans that do not require exercise or take into account the calories net of exercise. It can be looked at as being the amount of energy (measured in calories) expended by the body to remain in bed asleep all day! ( Source: )Īll too often, people contact me proposing a calorie intake that is at or below their RMR or BMR.
BMR is the minimum calorific requirement needed to sustain life in a resting individual. Here is a good BMR calculator: BMI-Calculator. BMR is just another way to calculate this, but it is a good number to understand if you are struggling with this issue. Calculate your RMR and use that number in the spreadsheet you’ll find in our breakdown of the P90X Nutrition Guide. You can find a better RMR calculator at . The P90X equation isn’t that precise, because it doesn’t take into account height or age and only relies on weight. RMR and BMR (Basal Metabolic Rate) are designed to provide the amount of calories your body would use if you did nothing, but rest, all day (no exercise). Understand RMR + BMR. Step 1 in calculating your calories with the P90X Nutrition Plan is calculating your Resting Metabolic Rate (RMR).That’s what your body has left to use, so don’t focus on 2,000, focus on 1,500 since that’s what your body has left to run your essential bodily functions and generally power your body through the day. Let’s say you’ve taken in 2,000 calories in a given day and you burned 500 doing Plyometrics X.
One of the most frequent questions I get from people is a concern that they are taking in too many calories to lose weight while doing P90X. Let’s talk about P90X and calorie deficit.
