As Steve mentioned, some people have trouble wrapping their mind around the idea that living a fit life isn't about calorie restriction—or restriction of any of the three major macronutrients, for that matter. It's about taking adequate amounts of healthy food to fuel your training. That may sound like what you're doing now, but to be safe, check out ON athlete Alex Carneiro's list of common fat-loss mistakes to make sure you're not sabotaging your results.
You don't want to end up overfed but undernourished. So you're going to start your journey by determining your basal metabolic rate, which is how many calories your body burns at rest. Then determine what's known as your "estimated energy requirements" using this calculator.
Total Calories Including Exercise
* Mifflin-St. Jeor Equation
This number is the amount of calories you use up over the course of an average day, including normal bodily functions and any training you might do. Don't worry about trying to stay above or below that number just yet. We'll get into that later in the trainer, on Day 22. For now, stay focused on learning.
If you've decided to continue tracking your food, then your challenge is to learn to use the apps, reference books, or one of the numerous helpful online databases to calculate how many calories you took in yesterday, today, or even better, both. Two of the most popular databases are NutritionData.com and the USDA's National Nutrient Database for Standard Reference, but there are a growing number of apps that utilize restaurant data if you're not near a computer.
