What are the major differences between these calorie plans? For the sake of argument, assume that 1000 is TDEE.  
  
I'm mainly concerned with the differences between eating more on particular days and spreading it out evenly.

(Calorie consumption)  
  
 | Day 1| Day 2 | Day 3 | Day 4 | 
---|---|---|---|---|
A | 0000 | 0000 | 0000 | **4000** |
B | **4000** | 0000 | 0000 | 0000 |
C | **1000** | **1000** | **1000** | **1000** |
D | **2000** | 0000 | **2000** | 0000 |  
  
* What happens to the body with each of these plans?
* Assuming calories were sufficient, some of these plans are bad for muscle growth, correct?
* Do over-eating on one day and under-eating on others cancel each other out?
