Hey man,
After reading your post I realized you have made a few glaring mistakes in your post. The first one being the supposed 'rep range' for specific goals, it is a myth that higher reps are for weight loss and lower reps are for muscle gain. You can gain muscle doing high reps (dynamic effort day, in the West Side barbell program) and you can lose weight doing low reps. At the end of the day if you want to lose weight you have to expend energy, now tell me which one expends more energy doing 25 reps at 50% of your 1RM or 5 reps with 80% of your 1RM? (1RM=1 Rep Max). Now, Vice Versa if you are trying to gain weight/muscle you can both do high reps and low reps, when trying to gain muscle the name of the game is progressive overload. If you progressively overload your muscles they have no option but to grow. You also mention that "animal protein is the main building material for a relief figure". Please show me a study that says that animal protein is the main building material of"a relief figure", which I assume you just meant muscle. Another thing is your claim that "After a workout, the body needs at least 48 hours to recover and become stronger.". Then how do people get stronger and bigger on 6 days a week programs? I think you may have misphrased this sentence though since 48 hours is around how long muscle protein synthesis stays above basal levels therefor being ideal for muscle and strength gains. I could rattle off a few more things but I'd probably just be nit picking at that point.
