Although I had fun making a little joke about this "not eating" phenomenon we see in our society, I do want to take this opportunity to explain the importance of the ofunit we use that measure how od when it comes to your training. Food is crucial to maximize results. Today, I am simply going to cover the topic of calories.
A calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. The amount of calories your body needs to perform its basic functions would be your Basal Metabolic Rate (BMR). Once you know your BMR, you will then be able to manipulate your calories and adjust them according to your goals.
A great site I use to calculate my BMR and my clients BMR is this one. This site will tell you how many calories you need to maintain your weight (without exercise), what you would need to do to maintain your weight with exercise, how to lose weight or gain muscle. It all starts with calories, and later you can break it down to Macronutrients (protein, carbs, and fat) if that is something you can monitor.
Remember one thing: eating fewer calories doesn't necessarily mean that you're eating better! Calories are essential to fuel your body for the day, to recover from workouts, and also to keep your metabolism healthy. If you aren't fueling your body properly, you can do some major damage that is EXTREMELY hard to reverse. More on metabolic damage in a future post!
