Something is wrong!

After several long rides of 100km+ and burning 4000 calories or more, I was expecting to be able to say that my weight had fallen by quite a bit.

It hasn't!

So, what is going on? I know that my muscle mass will have increased and that muscle is heavier than fat as it is more dense but I don't think this will account for the slight increase. If you are exercising for more than 90 minutes then you have to start to take on carbs in the form of sugar but even when I take this into account I should easily be in a negative calorific differential situation, by several thousand calories.

On a ride, I have a pocket full of jelly babies, fox's glacier mints, raisins, cereal bars and the odd gel pack. If you add the calories up, its about 400 calories and it is very high in carbs whilst keeping the fat content low.

I do know that on the following rest day, I am hungry and I eat more than normal, probably 2500 calories compared to my normal 2000. I do this to restore the glycogen stores in my muscles.

So, I just don't know what is going on, and would welcome your comments! I'm going to calorie track my intake for the next few days to see if it will shed any light into the situation.
