I am a little confused about the calories counting. I was reading in this book "Lose Weight or Gain Weight? Nutrition & Exercise" that I took from Amazon, that we should not count calories because that it does not help. The author was saying we need to calculate proteins and maybe carbs, but not calories. By the way, the author has a funny name "Samson" , but overall it is not a bad book, has lots of details but I personally don't have the time and will to keep up with those. Can somebody help me with this calories thing?
