Two things that are good to have around the house if your in training.
A block of low fat cheese,and pickles
Youd be suprised how far just a little nibble of cheese will take you, and lets face it if your in training,your sweating like a pig,which means your blowing your own salt by the bucket full.If you dont replenish it, you cramp up. Well what makes a pickle?
A cucumber soaked in brine
My wife didnt even used to like pickles,Ive seen her inhale a polish dill since she's been training
But again, no fat,no carbs, and its something your body was dying for anyway.
Now dont get me wrong,your body needs some carbs for energy,but you dont want them being empty carbs, like cookies, and for the love of god avoid cake like the plague it is
