Most athletes who are active need 6000+ calories just to maintain! Guys like myself who are active here and there still need 3000+ cal to maintain...and 4000+ to gain size. As your activity level goes up, so must your calorie intake. Start by adding 500 a day for a week and see if that makes a difference.
Also a VERY important question, how much protein are you getting daily (as in grams)? Most active people who have muscle mass need at LEAST 0.8-1.0grams/lb of lean body mass. That's a hell of alot of protein which you may not be meeting.
Also dont confuse muscle size with muscle. You may be losing stored glycogen from the muscles which will also shuttle out water. (think bodybuilding techniques of pumping up the muscle).
In the end there are lots of variables to IF that you need to be able to analyze and fine tune to make sure you are getting optimal results. My guess is not enough protein. You can also extend your eating hours to say 6-7hours to make sure you do get enough calories in. It's ALL about the daily calories and the adaquate protein intake for your active lifestyle.
Your "tiredness" comment also shows the lack of calories. Don't base it around high carbohydrates as you can use fat for fuel for walking, hiking, and other non-explosive glycogen based activities. Fat (healthy sources) is also a great concentration for calories (9grams/cal vs carbs at 4grams/cal). And as we know...it's about the daily calories.
One last side note about high carb intake. If you take 2 people and put them on a daily restrictive cal diet....one with high carbs, little protein....one with high protein, little carbs.....can you guess which one loses a ton of muscle and which one doesn't?
