Sorry, I do not know how to break it up into multi-sections to answer.
1) I normally do the whole calorie flip on a macro scale. Normally, I severely cut back on carbs mostly while keeping my Protein intake the same if not more than before. Fat intake is about the same but I eat more almonds to help me stay full. This works out really well for me,
BUT my problems comes in when I workout nonstop for 3-4 hours and continue to eat very little carbs. After that long duration, I would eat a banana (potassium+carbs) and have a scope of protein shake. That would keep me full for about 1 hour and then I would get really hungry but I can manage. My issue is that after that long workout, my mind and it's reaction is slowed; the best remedy for it is to eat tons of fast carbs like fruits but then it feels like I would be putting on the calories back that I worked so hard to burn. Would be like a dog chasing his tail.
(2,34) I have tried to lower my carbs intake slightly only before but the body does not seem to shed the weight or at least as fast as I would like which is 0.75-1.5 lbs per week. I basically reduce my carbs intake by half to be effective. My body runs on carbs and I cannot cut it off completely or near complete otherwise I will always feel hunger and irriatably.
Overall my diet is effective (really effective), its just after a long (2.5 hrs+) training session where getting my HR even to 115 bpm is difficult (drops to below 110 even doing cardio), my mental capacity is awful for next hour or 2. As for over the duration of the day, i do catch myself making more "careless" mistakes that I do not normally make especially driving.
OKay then!
If I can assist you in some fashion, let me know.
I have some experience in low-carbing/adjusting calories, macro-nutrients, etc, and performing depletion workouts (for partial or full depletion), and can give some pointers on how to deal with various issues.
Wish you much success!
I will be watching and posting to your log from time to time to check on the brotha!
