Calorie intake restriction while trying to gain strength seems not to be easy, and I have experienced with my own eyes an improvement from one workout to another, by simply eating more than usual in the three days rest in between.
I guess it is time to start tracking down macronutrients and calories. I would like to avoid that, and I am thinking about a complementary approach: not paying much attention to the scale (well, at least within some reasonable limits) for some time until achieving some decent results in my strength training, and then entering a phase in which I might try to loose weight while doing the exact amount of work each workout with the hope of forcing the body not to loose muscle during that phase.
I think that might have something to do with the words "bulking phase" and "cutting phase" that I have read here and there, but I am completely ignorant and the net is full of bad advise motivated by commercial interests.
Can anybody explain a bit on the matter before I do something unhealthy?. To phrase it more specifically: I would like to know if those "bulking" and "cutting" bodybuilding phases are essentially what I am pondering to do, and I would like general guidelines on how to do it, why should I (or should not) do it, perhaps some online references. What are the advantages of both approaches? (trying to gain strength and muscle at constant body weight vs bulking and then cutting).
