Thats my basic diet plan... my main question is how should I vary it ... like I heard if I eat too much my body will adjust its metabolism or something like that.
Two questions about that:
1) What happens if the metabolism slows down will I just not digest as much and expel or will it turn to fat.
2) what should I do ... just eat a bit less one day... and if so what should I cut down on??
