Why do we do it!

Well I've had a great week, still feeling the soreness from a full on week of training and a pretty good week of Nutrition, but then...... Along comes Friday night, all is going well until my boyfriend comes home with Pizza and Tim Tams (my favorite!!!!). Normally I could say no but since I had been so good all week and hadn't had or planned to have a free meal I thought I deserved some. So after 2 slices of pizza and way too many tim tams I was left feeling very average. I'm still so confused as to why we do it to ourselves as it really didn't taste that good! Anyway after feeling guilty all day today, I'm over it but still a little confused as why we can put in so much effort in to training (getting up at ridiculous hours and pushing ourselves so hard) only to blow it all with a pure tastebud pleaser! Maybe one day I'll work it out but until then I'll just keep plodding away day by day doing the best I can!
