Don't let it get you down it happens to everyone. The secret is to allow yourself something as a treat for a week's dedication. After a while, the treat is not needed because fitness and the right nutrition becomes part of your lifestyle and you don't think twice about it. You will also find after your body is used to eating good food and then you suddenly put crap in, it does not like it at all,lol. Don't look at it as a struggle look at it as self-improvement and the road to success . I have had 3 months off training because of moving and finances etc but I started again today and I am so happy even after one workout, sore but happy and will be posting the entire process starting in a day or so.
You will never achieve maximum productivity in your life unless you have a good balance with food and fitness that is a fact. So use that reason as fuel to keep plugging away :)...
I like the idea of a weekly treat, it will be something to look forward to and keep me going. My diet hasn't been consistent but my exercise has so that is a big victory right there. Just gotta work on the nutrition and not eat so compulsively. I will keep an eye out for your posts!
