A. Yes. As the amount of intensity of your workouts increases, your body will crave more calories to counteract the caloric burn and nutrients to rebuild muscle tissue. The key is to consume nutrient dense calories rather than calories from fast food and highly processed food.
The best way to counteract the craving for food is to start your day with a high protein breakfast which will fuel your muscles and set the tone for the rest of the day. Eggs and other high quality protein are an excellent way to set the body up for an anabolic state to not only build and repair muscle but will increase you metabolism and give you energy to fuel your day. I recommend eating 4-6 smaller meals throughout the day to prevent gorging on unhealthy food at the end of the day when you have allowed yourself to become ravenous hungry. The ideal is to consume the bulk of your caloric intake earlier in the day and taper down as the day progresses. This will allow for energy to make it through your day without disturbing sleep patterns. Your metabolism slows as evening approaches to allow your body to unwind and prepare for sleep. Consuming the bulk of your caloric intake in the evening may not only disrupt your sleep but will leave you more hungry by the time you are ready to eat later in the evening. The general rule is, "Eat breakfast like a king, lunch like a prince and dinner like a pauper."
Another tip I recommend is to increase your fiber intake. I have mentioned many times in previous blogs, fiber slows digestion which makes you feel full longer. Good sources of fiber include brown rice, oatmeal, various fruits and vegetables.
Keep an eye on your caloric intake for the day by tracking your nutrient intake. I have many of my clients using apps such as myfitnesspal which do all the calculating for you and allow you to keep accurate records. Plan your meals out for the day ahead of time to prevent eating food that will be counterproductive to your fitness goals.
Remember, just because you are working out, you don't have a license to dramatically increase your caloric intake or eat junk. All your hard earned muscle and athleticism will be obscured by a layer of subcutaneous body fat.
