I could write a lot about this issue but of course I say only two little princes. First of all, your brain needs carbohydrates, but also all your body needs carbohydrates for too many reasons, for example, all metabolic processes using carbohydrate as enzymes, nutrients cofactor, second messengers, hormone activators, etc. (eg such as protein synthesis, the citric acid cycle, beta oxidation ecc.) and with a low-carbohydrate diet most of the processes will be blocked.
Furthermore,there is also a risk to a genetic mutation, and predisposition to various diseases, but obviously you don't realize it now, but when you start to age. Today there are few people who avoid carbohydrate, and the few that still insist on avoid them is only because of the lack of medical information, nutrition, biochemistry and so on.
Exercise and nutrition are not bodybuilding magazines where anyone can write. If you want some advise, begins to read some Jeukendrup's studies and some good books of biochemistry, and you'll understand the important of carbohydrate in your diet.
However, I don't say that your diet is too bad, but I think it would be much more efficient for you increase carbohydrates and decrease some grams of proteins, and I'm sure that the performance will increase and body fat rate will reduce, and also you'll feel better and your diet will be more healty.
