I've started field hockey pre-season it's intense! But I've gained 10 pounds! WHY???

Question

Ok. I started like a week ago and i started at about 150. Since then I've been eating the same I've always been eating (breafast, lunch, dinner no snacks) since i've started I've gained 10 pounds and I wanna know what's up! When will I start losing weight??? The practices are intense. They are 2 and a half hours each. I've only missed one practice cuz i pulled a muscle. We usually end each practice by running a mile. When will I lose weight!?

Answer 1

When you exercise to build endurance for hockey, you are building muscle. Muscles weigh more than fat. You should be eating complex carbs, they help your body be stronger, and help with endurance.

Answer 2

You are more than likely gaining muscle not fat. You should probably alter your diet a little so that you make sure you're eating the right kinds of foods that provide energy for intense exercise. You'll probably lose some fat later on but you have to include the weight of your muscles in your total overall body weight.    

Answer 3

You're not going to gain ten pounds of muscle in a week, no matter how hard you work out.  However, it is completely possible to gain ten pounds from swelling, inflammation or water retention.  The muscle that you pulled may have some swelling that you haven't noticed.  When a part of your body swells, the kidneys increase the amount of water in your blood to keep up your blood pressure.  Muscle fatigue also causes inflammation, which is the same as swelling, but is distributed evenly throughout the affected muscles.  I think that a combination of these three factors are causing your weight gain.  Don't worry, you've probably already lost some fat.  You will start losing weight when your muscles adjust to the new exercise.  It is true that muscle weighs more than fat, and if you are losing weight through exercise your weight loss will be very slow.
