well i could say the same as ppl who lose weight and gain back more than they lost as the plan backfire.
similar to lose weight. if 1 go on a diet for 1 meal a day. u tries 6 mnths n lose weight and go back to normal meal. boom!
U push yourself in the gym. got injure boom!
u try to save as much as u can. 70% 80% 90%. after mnths you feel miserable and start to spend $ more than you have saved
