Diets, from their intrinsic nature are restrictive. Duh. And frankly, restrictions suck.
So get rid of them.
Figure out what you can do with your body when you give it free reign. Figure out what your body does when you give yourself permission to make good decisions. Figure out what potentional your body has to be as kick ass as you know it is.
If you're out grocery shopping--go ahead and stock up your fridge. Stuff it full with food! Since you're so interested in health, it's probably going to be all good food, right? YES. Make the choice to fill it to the brim with fruits, veggies, healthy carbs, a box of mac n cheese (if you so desire)--eerything that you would LIKE to be able to eat. And eat it. Discover how easy it is to make good decisions when you give yourself the opportunity. You'll find that you're full faster. You'll find that you have the means to prepare yourself the healthy meal you've been craving.
You'll find that you DO have control, once you GIVE yourself control.
