Like everyone else, I'm interested in maximum muscle retention and development while pursuing low body fat levels. I've got muscle to gain and fat to lose. So, in terms of nutrition, how low should I go in terms of carbohydrates and fats. Correct me if I'm wrong, but those who prescribe to a higher carbohydrate load (i.e., Zoners) seem to have to worry more about macronutrients and precise balances and caloric consumption, while those who eat low carb and are fat adapted tend to have an easier time remaining lean, but what they have to worry about is training capacity. Am I right in this? I guess I'm looking for the "magic number" in terms of carbohydrate consumption that would give one adequate energy but also not enough to sabotage the "fat adapted" model. I hope this clarifies the question. If not, please let me know.
